NEUMANN KH 310 A

Product overview

The NEUMANN KH 310 A is a three-way, tri-amplified active nearfield studio monitor with a dedicated midrange dome, a sealed cabinet and a Mathematically Modelled Dispersion (MMD) waveguide: expanded midrange precision and a dry bass sound.

With its specially designed midrange driver, the compact KH 310 is particularly suited for precise work with speech, vocals, guitars and other instruments that have a midrange emphasis. Its closed design enables a very fast transient response, and the associated low harmonic distortion guarantees a neutral reference sound. Thermally protected Class AB amplifiers deliver 210 W and two times 90 W. It comes in a left-hand and a right-hand version.

Key features

• Dedicated midrange driver: 75 mm fabric dome with neodymium magnet and low stray field, for speech and vocals
• Sealed cabinet: lower group delay, precisely controlled transients
• Bass down to 34 Hz and up to 116.3 dB SPL
• In-house simulated alloy fabric dome tweeter with metal grille in an elliptical MMD waveguide
• Long-throw woofer with ELFF, magnetic shielding and die-cast basket
• 4-position bass, low-mid and treble acoustical controls; dimmable two-colour logo; ground lift
• Universal switched-mode power supply (100 - 240 V)
• Any KH 310 is pair-matched to any other KH 310 thanks to individual hand alignment

A solid bass foundation, high impulse fidelity

With its powerful switched-mode power supply and tri-channel amplifiers, the KH 310 reaches up to 116.3 dB while keeping a high-resolution, neutral reproduction across the whole frequency range, with bass down to 34 Hz. For most applications the bass extension is enough to work cleanly on the mix without a supplementary subwoofer, and the closed cabinet reproduces almost the entire frequency range at the same time.

Ultralight midrange dome

The fabric midrange dome captures the middle frequencies with utmost precision: its ultralight material and powerful neodymium magnet give a significantly better transient response with considerably less distortion. The alloy fabric dome tweeter ensures distortion-free clarity in the treble.

Applications

Nearfield applications in project, music, broadcast and post-production studios for recording, mixing and mastering, as front loudspeaker in mid-sized multichannel systems, as rear loudspeaker in larger ones and in OB vans. Connected to a KH 750 DSP subwoofer, it can be included in MA 1 room correction.

NEUMANN KH 310 A: frequently asked questions

What is the difference between the left and right versions?

The driver layout is mirrored. Neumann notes that a left can also be used in the right position and vice versa, and both can be used as a centre loudspeaker.

Is the KH 310 A ported?

No. It has a sealed (closed) cabinet, which gives a lower group delay and precisely controlled transients.

Which acoustical controls does it have?

Bass 0 to -7.5 dB, low-mid 0 to -4.5 dB and treble +1 to -2 dB, each in four steps.

What is the recommended listening distance?

1.0 to 2.5 m (feasible 0.75 to 6.0 m).

Where can I buy the NEUMANN KH 310 A in India?

The NEUMANN KH 310 A is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: Vocal and speech mixing

Engineers working on vocals, dialogue and voice-over.

Connections

Setup

1. Place the left version on the left and the right version on the right, at ±30°.
2. Point the acoustical axis at the listener.
3. Set bass, low-mid and treble for the room.
4. Set the level.

Tip: The dedicated midrange dome is made for speech and vocals.

Workflow 2: Nearfield mixing and mastering

Music studios that want bass without a subwoofer.

Connections

Setup

1. Set up the pair at 1.0 - 2.5 m.
2. Use the acoustical control starting points of the manual.
3. Calibrate with pink noise.
4. Mix and master.

Tip: Bass extension to 34 Hz is enough for most applications without a subwoofer.

Workflow 3: Setting the acoustic level

Anyone calibrating a monitoring level.

Connections

Setup

1. Set OUTPUT LEVEL to 94 dB SPL and INPUT GAIN to -15 dB.
2. Play pink noise at -18 dBFS (Europe) or -20 dBFS (USA).
3. Measure at the listening position with a C-weighted, slow sound level meter.
4. Set OUTPUT LEVEL and INPUT GAIN for the desired level.

Tip: Film: 85 dB(C); broadcast: 79 to 83 dB(C).

Workflow 4: Adding a KH 750 DSP subwoofer

Rooms that want room correction for analog monitors.

Connections

Setup

1. Connect the KH 310 A pair to the subwoofer outputs.
2. Activate bass management.
3. Run the MA 1 automatic alignment through the subwoofer.
4. Fine-tune levels.

Tip: The subwoofer's DSP makes MA 1 room correction available to the analog KH 310 A.

Workflow 5: Multichannel post production

Post and broadcast rooms.

Connections

Setup

1. Use KH 310 A monitors as front loudspeakers in mid-sized systems or as rear loudspeakers in larger ones.
2. Arrange to the surround standard.
3. Use left / right versions symmetrically; both can serve as centre.
4. Calibrate all channels.

Tip: Any KH 310 is pair-matched to any other.

Workflow 6: Dark rooms and behind-screen use

Film mixing stages and dimmed control rooms.

Connections

Setup

1. Set the logo brightness to 60 %, 30 % or off.
2. Use GROUND LIFT if hum comes from the source cabling.
3. Fit the optional GKH 310 grille to protect the drivers.
4. Check the level.

Tip: The dimmable logo suits low light and behind-the-screen installations.
