PRODUCT OVERVIEW\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe MOTU 848 is a professional Thunderbolt 4 \/ USB4 audio interface representing the latest generation of MOTU's flagship studio product line. Occupying the top of MOTU's rack-mount interface range, the 848 delivers 28 inputs and 32 outputs — 60 simultaneous audio channels — in a standard 1U rackmount chassis, combining cutting-edge converter technology, a built-in 64-channel DSP mixer, onboard AVB audio networking, and universal Thunderbolt 4 \/ USB4 connectivity. The 848 is designed for professional recording studios, post-production facilities, broadcast environments, houses of worship, educational institutions, and live sound applications where channel count, audio quality, and system flexibility are paramount.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eMOTU has been a pioneer in professional audio interface technology since 1986, and the 848 carries forward decades of proven driver engineering and system design. Its headline feature is the adoption of Thunderbolt 4 and USB4 (USB 4.1 Gen 3) connectivity, operating at up to 40 Gbps — delivering 256 channels of computer I\/O (128 in \/ 128 out) over a single cable at sample rates up to 96 kHz. This positions the 848 as one of the highest-bandwidth audio interfaces available to working professionals. The included 40 Gbps USB-C cable negotiates the fastest connection speed supported by the host computer, providing backward compatibility with Thunderbolt 3, USB3, and USB2 hosts without any hardware reconfiguration.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eAt the heart of the 848's audio performance is ESS Sabre32 DAC technology — the same converter architecture found in reference-grade digital-to-analogue converters used in high-end audiophile and broadcast equipment. ESS Sabre32 converters are renowned for their use of Hyperstream modulation and time-domain jitter elimination, producing a measured dynamic range of 125 dB (A-weighted) on the line outputs, THD+N of -114 dB (0.0002%) on both line inputs and outputs, and an equivalent input noise (EIN) of -129 dBu on the four microphone preamp channels. These figures place the 848 at or near the top of its class in any objective measurement.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eBeyond raw audio performance, the 848 integrates a 64-channel 32-bit floating-point DSP mixer with 4-band double-precision parametric EQ, high-pass filters, gate, and compression on every channel and bus — all controllable via the CueMix Pro application on macOS, Windows, and iOS. Onboard AVB networking through dual Gigabit Ethernet ports allows multiple 848 and compatible MOTU AVB devices to be networked together across a facility, with AVB's guaranteed 2 ms network latency and support for up to 128 channels per device. A 3.9-inch 480×128-pixel 24-bit RGB TFT display on the front panel provides at-a-glance metering, signal status, and hardware configuration access.\u003c\/p\u003e\n\n\u003chr style=\"border: none; border-top: 1px solid #E8E8E8; margin: 28px 0;\"\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003e2. COMPUTER CONNECTIVITY\u003c\/h5\u003e\n\n\u003ch5 style=\"font-size: 15px; font-weight: 700; color: #006D77; margin-top: 20px;\"\u003e2.1 Thunderbolt 4 \/ USB4 Universal Interface\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe 848 features two Thunderbolt 4 \/ USB4 Type-C ports, each capable of operating at up to 40 Gbps. This is not merely a USB-C interface with Thunderbolt branding — the 848 fully implements the Thunderbolt 4 specification, including Intel's guaranteed minimum bandwidth allocation, daisy-chaining support for up to six Thunderbolt devices, and compatibility with Thunderbolt 3 hosts. The second Thunderbolt port is available for daisy-chaining peripherals such as additional MOTU interfaces, external storage, USB hubs, or Thunderbolt docks, all sharing the 40 Gbps pipe.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe included cable is a 2-metre, 40 Gbps \/ 240W USB-C cable that is Thunderbolt-compatible. This single cable connection carries all audio I\/O data to and from the host computer while also delivering up to 15W of power downstream for compatible peripherals. When connected to a USB3 host (without Thunderbolt), the 848 automatically negotiates USB3 operation, delivering 128 channels of host I\/O at 44.1\/48 kHz or 88.2\/96 kHz. USB2 class-compliant operation (no driver required) delivers 64 channels at 44.1\/48 kHz. The ability to operate as a USB audio class-compliant device means the 848 works immediately with any macOS or iOS host without installing any drivers — an important advantage for touring and rental applications.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eRound-trip latency (RTL) is measured at approximately 1.8 ms at 96 kHz with a 32-sample host buffer in a high-performance DAW such as Digital Performer. This figure represents the total latency from analogue input through the ADC, through the host computer's audio engine, through the DAC, to analogue output — the most relevant latency measurement for live monitoring and overdubbing applications. At 44.1 kHz or 48 kHz with larger buffers, the 848 delivers stable, glitch-free operation even on complex sessions with many plug-ins.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700;

ESS Sabre32 converters utilise a 32-bit Hyperstream DAC modulator — a proprietary multi-bit sigma-delta topology that processes audio at 32 bits of internal resolution before noise-shaping and filtering. Unlike conventional multi-bit or single-bit sigma-delta DACs, Hyperstream minimises noise across the entire audio band by distributing quantisation energy far outside the audible range. The result is a measured dynamic range of 125 dB (A-weighted) on the line outputs — a figure that approaches the theoretical limit of 24-bit audio (nominally ~144 dB at 0 dBFS) while reflecting the real-world limits of analogue circuit noise floors.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eTotal Harmonic Distortion plus Noise (THD+N) on both line inputs and outputs is specified at -114 dB, equivalent to 0.0002%. This is an exceptionally low distortion figure that can only be achieved through careful circuit design: shielded power supply topologies, matched differential input stages, precision voltage references, and thermally stable gain stages. The microphone preamps achieve the same -114 dB THD+N figure, which combined with an Equivalent Input Noise (EIN) of -129 dBu places them among the quietest preamps in any interface product at any price point.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe analogue-to-digital converters (ADC) for the line inputs achieve a dynamic range of 120 dB (A-weighted) — 5 dB below the DAC figure, which is typical and physically expected, as ADC noise floors are constrained by the thermal noise of the input circuitry preceding the converter. The +21 dBu maximum signal level on all analogue inputs and outputs provides approximately 21 dB of headroom above a nominal 0 dBu operating level, ensuring the 848 can accommodate the hot output levels common in professional-grade outboard gear and mixing consoles without clipping.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px;

Each preamp delivers +74 dB of gain range in 1 dB increments — an unusually wide range that accommodates everything from hot line-level sources (gain near minimum) to passive ribbon microphones requiring 60–70 dB of clean gain. The -20 dB pad on each channel extends the effective input range to handle signals up to +20 dBu without engaging the preamp's gain structure, useful for high-output condenser microphones placed close to loud sources.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe EIN of -129 dBu is the critical figure for evaluating microphone preamp transparency. EIN is the noise voltage at the preamp input referred back to a theoretical noise-free measurement point, expressed in dBu. A value of -129 dBu means that with maximum gain applied and the input terminated with a standard 150-ohm source impedance, the preamp adds less self-noise than the Johnson-Nyquist thermal noise generated by the source impedance itself. In practical terms, this means ribbon and passive dynamic microphones — notoriously challenging loads requiring 60–70 dB of gain — will be amplified with inaudible self-noise even in quiet studio environments.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eEach XLR\/TRS combo jack alternatively accepts a 1\/4-inch TS high-impedance (hi-Z) guitar input on the TRS insert, with an input impedance of 1 MΩ on the line\/instrument inputs. This allows direct injection (DI) recording of electric guitar or bass without an active DI box — the high impedance correctly loads the guitar's passive pickups, preserving the instrument's natural tonal character. Microphone inputs 3 and 4 each include a dedicated send\/return insert loop for outboard gear: patch a hardware compressor, EQ, or noise gate into the signal chain before the ADC, operating via balanced TRS connections. When mic inputs 3–4 are not in use, their insert returns serve as two additional balanced TRS line inputs.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eAll four preamp channels include 48V phantom power (independently switchable), -20 dB pad (independently switchable), and phase invert — all remotely controllable from CueMix Pro running on a connected Mac, PC, or iOS device. This remote control capability is practically valuable in studio environments where the engineer is seated at a mixing position away from the rack-mounted 848.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px;

A +20 dB digital gain trim is available on each input channel from CueMix Pro, allowing calibration for sources operating at different nominal levels (e.g., +4 dBu professional gear versus -10 dBV consumer equipment). Combined with the four mic\/instrument channels, the 848 offers a total of 12 discrete analogue inputs (plus two additional insert returns), providing flexible connectivity for mixing consoles, outboard processors, synthesisers, drum machines, and other line-level sources.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe 848 features 12 balanced 1\/4-inch TRS analogue outputs, all DC-coupled. DC coupling — the absence of an output coupling capacitor — is normally reserved for laboratory and test equipment, where it allows measurement of signals down to DC (0 Hz). In a professional audio context, DC coupling serves a different purpose: it permits the 848's line outputs to be used as Control Voltage (CV) sources for Eurorack and other modular synthesiser systems. By routing DAW automation data to an output channel, a user can transmit precise voltage signals that modulate oscillator pitch, filter cutoff, envelope timing, or any other voltage-controlled parameter in a modular system — without any additional hardware. A -99 dB digital trim is available on each output channel for fine-level calibration. The twelve outputs support configurations up to 7.1.4 Dolby Atmos, making the 848 directly compatible with immersive audio production workflows.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700;

The headphone outputs deliver a maximum of 13.3 dBu into a standard headphone load, with an output impedance of less than 1 Ohm. A sub-1-ohm output impedance is significant: it ensures that the headphone driver can accurately control the headphone transducer regardless of the headphone's own nominal impedance (whether 32 Ohm consumer-grade or 250 Ohm professional studio headphones), preventing the \"damping factor\" degradation that causes headphones to sound loose or resonant when driven from high-impedance sources.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eEach headphone output can be independently assigned to any audio source: the main stereo output pair, any other analogue output pair, any mixer bus, any computer output channel pair, or a completely custom mix created in CueMix Pro — including live microphone feeds with built-in reverb for comfortable monitoring during tracking.

At 1x sample rates (44.1\/48 kHz), each bank carries 8 channels of ADAT Lightpipe audio, for a total of 16 ADAT channels in and 16 out. ADAT Lightpipe is the industry-standard optical protocol for digital audio expansion, supported by a vast ecosystem of devices including outboard AD\/DA converters, digital mixing consoles, optical expanders, and other audio interfaces. At 2x sample rates (88.2\/96 kHz), each ADAT bank switches to S\/MUX (Sample Multiplexing) mode, which carries 4 channels per bank (8 total) by interleaving adjacent sample frames across adjacent ADAT channels. This halving of channel count at double sample rate is a fundamental property of the S\/MUX protocol and is reflected in the 848's total channel count figures.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eBank A additionally supports optical S\/PDIF (TOSLink) I\/O, switchable via CueMix Pro. This allows the 848 to connect to consumer DAT recorders, CD players, optical-equipped mixing consoles, and any other TOSLink device — at sample rates up to 96 kHz. The Word Clock I\/O via BNC connectors enables the 848 to lock to an external master clock or to act as master clock for an entire digital audio system, supporting all sample rates from 44.1 to 192 kHz. Proper word clock synchronisation between multiple digital devices is essential to prevent the sample-rate discontinuities and jitter-induced noise artefacts that result when converters operate on unsynchronised clocks.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003eDIGITAL I\/O SPECIFICATIONS\u003c\/h5\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 18px 0; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #0D1B3E;\"\u003e\n\u003cth style=\"text-align: left; padding: 10px 14px; color: #FFFFFF; border: 1px solid #0D1B3E;\"\u003eSPECIFICATION\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 10px 14px; color: #FFFFFF; border: 1px solid #0D1B3E;\"\u003eDETAILS\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eOptical Banks\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e2 (Bank A and Bank B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eADAT Channels @ 44.1\/48 kHz\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e8 ch per bank = 16 ch total in \u0026amp; out\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eS\/MUX Channels @ 88.2\/96 kHz\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e4 ch per bank = 8 ch total in \u0026amp; out\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eTOSLink \/ Optical S\/PDIF\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eBank A: switchable to stereo TOSLink up to 96 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eOptical Connector Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eTOSLINK (JIS F05; standard optical audio)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eWord Clock In\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e1 × BNC, all sample rates 44.1–192 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eWord Clock Out \/ Thru\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e1 × BNC, all sample rates 44.1–192 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eWord Clock Sync\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eLocks entire digital system to external master clock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eInternal Clock\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eCrystal-based; acts as master clock for connected digital devices\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003chr style=\"border: none; border-top: 1px solid #E8E8E8; margin: 28px 0;\"\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003e8.

The 32-bit floating-point processing format provides over 1,500 dB of theoretical headroom, ensuring that even complex mix matrices with multiple summed channels never clip internally.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe 64-channel mixer accepts inputs from any combination of sources: the 848's physical analogue inputs, its optical digital inputs, computer playback channels (DAW tracks routed to the interface), and AVB audio network streams from other connected devices. All 64 inputs can be routed to any combination of the mixer's 32 output buses. The bus architecture includes 26 auxiliary buses for headphone cue mixes, monitor feeds, and effects sends, plus dedicated main, reverb, monitor, and solo buses. This is equivalent to the busing architecture of a mid-size hardware mixing console.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eEvery input channel and every output bus in the 64-channel mixer includes a four-band double-precision parametric EQ. \"Double-precision\" in DSP terms means that the EQ computations are performed at 64-bit floating-point resolution internally, preventing the coefficient rounding errors and limit cycles that can cause subtle artefacts in 32-bit-only EQ implementations, particularly in high-Q filter configurations at low frequencies. Input channels additionally include a high-pass filter and a gate. All channels and buses also include a compressor with threshold, ratio, attack, release, and gain controls. The reverb processor is a separate send effect available to all channels.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px;

PATCHBAY, ROUTING \u0026amp; ROUTING GRID\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eCueMix Pro's Patchbay view provides a visual, virtual patch-cord interface for routing any signal source to any destination in the 848 system. Sources include the 848's analogue inputs, optical digital inputs, computer playback channels, mixer bus outputs, and AVB network audio streams. Destinations include analogue outputs, headphone outputs, optical digital outputs, computer record inputs, mixer inputs, and AVB network streams. Unlike a fixed mixer architecture, the Patchbay allows arbitrary point-to-point connections and — critically — source splitting: a single mono source or stereo pair can be simultaneously routed to an unlimited number of destinations without any signal degradation, since digital splits are arithmetically lossless.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe Routing Grid provides a matrix-style \"bird's-eye\" overview of all signal routing in the system, displaying all sources and destinations in a two-dimensional grid. Activity meters on each grid intersection allow engineers to verify signal presence without returning to individual channel views. The Routing Grid is particularly valuable when managing large channel-count sessions where multiple optical banks, computer channels, and network streams are all active simultaneously — a session topology common in broadcast studios, post-production facilities, and large educational institutions.\u003c\/p\u003e\n\n\u003chr style=\"border: none; border-top: 1px solid #E8E8E8; margin: 28px 0;\"\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003e10.

Unlike standard Ethernet, which operates on a best-effort delivery model, AVB allocates guaranteed bandwidth reservations on the network — ensuring that audio streams are never delayed or interrupted by competing network traffic. The 848 implements a fully compliant AVB stack with two built-in Gigabit Ethernet ports that function as an integrated two-port AVB switch, enabling daisy-chaining of up to eight AVB-compatible devices without external switching hardware.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eAVB network latency — the point-to-point audio transmission delay — is fixed at 2 ms throughout the network, regardless of cable length (up to 100 metres per segment with standard CAT-5e or CAT-6 cable, or far longer with fibre-optic cable), the number of daisy-chained devices, or the number of AVB switches in the signal path. This deterministic latency is a fundamental property of AVB's Credit-Based Shaper mechanism, which paces audio packet transmission to prevent buffer overflow. A 2 ms network latency is imperceptible in live monitoring applications and well within the tolerances required for synchronous multiroom recording.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eEach 848 can transmit and receive up to 128 audio channels to and from the AVB network at sample rates up to 96 kHz, organised as 16 configurable streams of 1–8 channels each. At 176.4\/192 kHz, the stream count reduces to 8 streams. The 848 is fully compatible with all previous-generation MOTU AVB devices (16A, 8M, 112D, 1248, etc.), enabling mixed-generation networks where older devices expand a new 848 installation. CueMix Pro's 1722.1 controller functionality also allows management of third-party AVB devices on the same network.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E;

This display provides real-time metering for all analogue and digital I\/O simultaneously, with customisable meter views that can show analogue I\/O only, digital I\/O only, or any combination. The 24-bit colour depth allows the display to use colour-coded signal status indicators (e.g., green for nominal levels, amber for approaching clip, red for clip) with full colour fidelity rather than the limited palettes typical of OLED or character-LCD displays.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe front panel provides extensive hardware control: four encoders for preamp gain (one per mic channel), two encoders for headphone volume, one large encoder for main output volume, one encoder and two switches for menu navigation, four switches for -20 dB pad (one per mic channel), four switches for 48V phantom power (one per mic channel), and six control room switches. The control room switches include A\/B\/C monitor select (for switching between three monitor sets), mute, mono (sum to mono), and talkback.

It provides complete access to every 848 function: device settings, preamp gain and phantom power control, signal routing in both Patchbay and Routing Grid views, the full 64-channel mixer with EQ, dynamics, and effects, and AVB network management. CueMix Pro can run simultaneously on multiple devices — for example, an engineer at a macOS workstation and a musician with an iPhone can both access the mixer at the same time, with changes from either device reflected immediately on all connected CueMix Pro instances.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe 848 is controllable over Wi-Fi through CueMix Pro, provided the controlling device and the 848 (connected to the same computer on the network) share a common Wi-Fi network. This wireless control capability is particularly valuable in live performance, education, and large-facility scenarios where walking to the rack to adjust a preamp gain or monitor mix is impractical. The iOS version of CueMix Pro supports iPad models with M-series processors for full low-latency Thunderbolt operation, extending the 848's utility to iPad-based professional audio workflows.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eIncluded software also comprises MOTU Performer Lite — a full digital audio workstation based on Digital Performer technology — providing multitrack recording, editing, mixing, and mastering capability immediately upon unboxing.

BUILD QUALITY \u0026amp; FORM FACTOR\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe MOTU 848 is housed in a standard 1U, 19-inch rack-mount chassis — the universal form factor for professional audio equipment that mounts in standard EIA 310-D equipment racks. At 1U height (1.75 inches \/ 4.44 cm), the 848 occupies the minimum possible rack space while providing 28 inputs and 32 outputs. The chassis depth of 12.25 inches (31.1 cm) is compatible with standard 14-inch and deeper equipment racks. At 11 lbs (5 kg), the 848 is a solid, road-worthy unit suitable for both permanent studio installation and touring racks.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe chassis is constructed from steel with a powder-coat finish typical of MOTU's professional product line. The rear panel carries all permanent signal connections — TRS line inputs, TRS line outputs, optical I\/O banks, BNC word clock connectors, and dual Gigabit Ethernet ports — allowing the unit to be rack-mounted with all cabling at the rear in a tidy, professional installation. The internal power supply is a universal auto-switching unit (100–240V, 50–60 Hz), eliminating the need for a voltage converter when deploying the unit in international environments, a common requirement for touring and broadcast production.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003ePHYSICAL SPECIFICATIONS\u003c\/h5\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 18px 0; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #0D1B3E;\"\u003e\n\u003cth style=\"text-align: left; padding: 10px 14px; color: #FFFFFF; border: 1px solid #0D1B3E;\"\u003eSPECIFICATION\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 10px 14px; color: #FFFFFF; border: 1px solid #0D1B3E;\"\u003eDETAILS\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eRack Height\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e1U (1.75 inches \/ 4.44 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eRack Width\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e19 inches \/ 48.26 cm (standard EIA 310-D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eDepth (enclosure only)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e12.25 inches \/ 31.1 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e11 lbs \/ 5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003ePower Supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eInternal; universal auto-switching 100–240V, 50–60 Hz, 1.0A max\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003eMax 100–240V × 1.0A = up to ~240W draw (actual significantly lower)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eDownstream Power (USB)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e15W to connected downstream USB peripheral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eFront Panel Connections\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e4 × combo XLR\/TRS; 2 × 1\/4\" TRS headphone; display; encoders; switches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #F7F7F7;\"\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0; font-weight: 600;\"\u003e\u003cstrong\u003eRear Panel Connections\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 14px; border: 1px solid #E0E0E0;\"\u003e8 × 1\/4\" TRS line in; 12 × 1\/4\" TRS line out; 2 × ADAT optical I\/O; 2 × BNC word clock; 2 × Gigabit Ethernet; 2 × USB-C (Thunderbolt 4\/USB4)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003chr style=\"border: none; border-top: 1px solid #E8E8E8; margin: 28px 0;\"\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003e14. LOOPBACK, LIVE STREAMING \u0026amp; ADVANCED FEATURES\u003c\/h5\u003e\n\n\u003ch5 style=\"font-size: 15px; font-weight: 700; color: #006D77; margin-top: 20px;\"\u003e14.1 Loopback Recording and Live Streaming\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe 848 supports loopback routing — the ability to route the computer's own audio output back into the computer as a record input. This is the fundamental requirement for live streaming and podcast production workflows where the engineer needs to mix computer audio (backing tracks, software instruments, remote guest audio via VoIP) together with live microphone inputs and present the combined signal to streaming software such as OBS Studio, StreamYard, or Zoom. The 848's patchbay makes loopback routing fully configurable: any number of computer output channels can be looped back as computer input channels, mixed with live sources in any proportion.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 15px; font-weight: 700; color: #006D77; margin-top: 20px;\"\u003e14.2 Guitar Re-Amping\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eThe hi-Z inputs on the 848's combo jacks are designed for professional re-amping workflows. During a recording session, the guitarist connects directly to the 848's hi-Z input, and CueMix Pro routes the signal through the near-zero-latency DSP mixer to a line output connected to a guitar amplifier, while simultaneously recording the dry DI signal to the DAW. The guitarist monitors through the amplifier in real time with negligible latency. After the session, the dry DI track can be routed back through the same line output to a different amplifier — or through amp modelling software — for tonal experimentation without re-recording the performance. A re-amp box (impedance adapter) may be inserted in the signal path when required for proper impedance matching.\u003c\/p\u003e\n\n\u003ch5 style=\"font-size: 15px; font-weight: 700; color: #006D77; margin-top: 20px;\"\u003e14.3 CV \/ Modular Synthesis Integration\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eDC coupling on all 12 line outputs means the 848's analogue outputs can pass signals from 0 Hz (DC) through 20 kHz without attenuation. Eurorack modular synthesiser systems use control voltages typically in the range of 0–10V or ±5V to control pitch (1V per octave), filter cutoff, amplitude, and other parameters. By routing DAW automation lanes or dedicated CV generator plug-ins to the 848's line outputs and connecting those outputs to a Eurorack system via appropriate voltage-scaling hardware, a composer or sound designer can drive modular systems with precise, repeatable, time-aligned control voltages synchronised to the DAW session clock.\u003c\/p\u003e\n\n\u003chr style=\"border: none; border-top: 1px solid #E8E8E8; margin: 28px 0;\"\u003e\n\n\u003ch5 style=\"font-size: 18px; font-weight: 700; color: #0D1B3E; border-bottom: 2px solid #006D77; padding-bottom: 8px; margin-top: 32px;\"\u003e15.

PRODUCT CONTEXT: MOTU 848 VS. SIBLING MODELS\u003c\/h5\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eWithin MOTU's current professional interface range, the 848 sits above the 828 (which offers a similar I\/O footprint with USB\/Thunderbolt connectivity but without the 848's Thunderbolt 4\/USB4 bandwidth tier) and above the 16A (an AVB-primary interface designed for networked expansion rather than direct computer hosting). The 848's defining advantage over both is the combination of Thunderbolt 4\/USB4 at 40 Gbps with the ESS Sabre32 DAC technology's 125 dB dynamic range — specifications not previously available together in a single-rackspace MOTU interface. The 848 retains the 828's operational model (direct USB\/Thunderbolt host connection with full standalone mixing capability) while adding the next generation of conversion quality and connectivity bandwidth.\u003c\/p\u003e\n\n\u003cp style=\"margin: 14px 0;\"\u003eCompared to competitor interfaces at a similar channel count and price point, the 848's distinguishing features are the integrated AVB networking (unusual in this class), the DC-coupled outputs (enabling modular synthesis without add-on hardware), the 64-channel onboard DSP mixer with full dynamics processing (reducing dependence on host CPU resources), and the 3.9-inch colour TFT display (providing real-time visual feedback without opening a software application). The combination of all these features in a single 1U chassis positions the 848 as one of the most comprehensively featured professional audio interfaces available at any price.\u003c\/p\u003e\n\n\u003c\/div\u003e","brand":"Shivansh Electronics","offers":[{"title":"Default Title","offer_id":52780886524271,"sku":"MOTU-848","price":170000.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/4766\/0399\/files\/MOTU-848-SHIVANSH-ELECTRONICS-KOLKATA-THUMBNAIL.svg?v=1787000607","url":"https:\/\/shivanshelectronics.in\/products\/audio-interfaces-motu-848","provider":"Shivansh Electronics","version":"1.0","type":"link"}
