SSL pre-amp and Legacy 4K

Channel 1 is a bus-powered, low-noise SSL microphone pre-amp with a 63 dB gain range and an EIN of -130.5 dBu (A-weighted), with +48 V phantom power and a 75 Hz, 18 dB/octave high-pass filter. Legacy 4K Analogue Enhancement distils two key elements of the 4000-series console sound into a single analogue circuit: a carefully controlled amount of sweet-sounding harmonic distortion and a forward yet musical high-frequency boost, particularly pleasant on vocals and acoustic guitar.

Instrument and line input

Channel 2 captures DI guitar and bass on its 1 MΩ instrument input, or synths, drum machines and samplers with LINE engaged (10 kΩ, up to +24.5 dBu), keeping every take rich, dynamic and full of tone.

Monitoring and loopback

The MIX button sums the near-zero latency inputs (under 1 ms) with USB playback for comfortable monitoring while recording. Three stereo loopback pairs route the interface outputs back into inputs 3-8 internally, so system audio, music beds and effects can be captured alongside the microphone for podcasts and live streams.

Built to move with you

Rugged and compact, SSL 1 is class compliant on computers and USB Audio Class 2.0 mobile devices, with an ASIO / WDM driver for the other main computer platform. Power it over the USB port, or from a 5 V phone charger or power bank on the 5V EXT port to save the battery of a mobile device.

SOLID STATE LOGIC SSL 1: frequently asked questions

Does SSL 1 need a separate power supply?

No. It is powered by the computer over USB, or by a 5 V source such as a phone charger or power bank on the 5V EXT port.

Can I record a guitar directly?

Yes. Plug the guitar or bass into input 2 with the LINE switch off: the instrument input offers 1 MΩ impedance.

Can I use SSL 1 with a phone or tablet?

Yes. SSL 1 is plug-and-play with USB Audio Class 2.0 mobile devices; power it from 5V EXT to reduce battery drain. It does not charge the connected device.

What is loopback for?

It records computer audio, such as a media player or application sound, into inputs 3-8 without cables: ideal for streaming, podcasting and content creation.

Where can I buy the SOLID STATE LOGIC SSL 1 in India?

The SOLID STATE LOGIC SSL 1 is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.
