DACS Clarity HeadLite III B - Four Channel Headphone Amplifier with Balanced Inputs

DACS Clarity HeadLite III B - Four Channel Headphone Amplifier with Balanced Inputs


DACS Clarity HeadLite III B – 4-channel Headphone Amplifier

Headphones are increasingly important for many aspects of audio production. The quality of headphone design and manufacture is higher now than it has ever been. Ensuring the very best performance from these headphones requires they be driven by a dedicated headphone amplifier. These days “making do” with the headphone socket from the mix board just doesn’t really do at all.  Especially when there is more than one set of ears which need to listen in.

Clarity and Sound Quality

Whatever the headphone task the quality of the final result begins with whatever you can hear in your ears. Accurate representation of the whole audible frequency range is essential and any over-emphasis of certain bands, or overall mud or indistinctness in the sound, will inevitably affect both the overdub and the overview. The metering added to the busses that feed the amplifiers allows users to set their input levels, making sure what goes in to the amplifier will give optimum output performance.


Amplifier power is not just about level (sound pressure level) it is about clean level (sonically pure level). A cheap headphone amplifier when pushed beyond its narrow limits can begin to distort before your headphones or your ears. Something that not only compromises the sound you can hear, it can also damage your hearing. A headphone amp which has enough power should be `cruising’ for the whole of its useable range. So the output signal is always as clean as the technical specifications indicate it should be.


The DACS Clarity HeadLite III B like all of our products are designed in the field by working engineers and developed by industrious boffins. It scores top marks in all of the above: Excellent Clarity and Sound Quality is ensured by the design of the amplifier which produces very low distortion and an extended and flat frequency range.

The Power of the output on the standard channels is more than sufficient to drive any headphone of any impedance. Special higher power channels can be specified to drive multiple headphones without loss of volume.


In a studio you might use more than one set of headphones, without every listener wanting the same source. So a good headphone amplifier will provide multiple outputs with individual amplifiers for each and a choice of inputs.

In the HeadLite III B this is provided by four bussed inputs selectable in combination on each of the four stereo output amplifiers and eight physical outputs. The standard channel amplifiers of HeadLite III B have power to spare. 125mW RMS into 150 Ohms – and each will easily and cleanly drive 400 Ohm headphones at possibly unwise maximum output levels. We can fit HeadLite III B with high power channels for driving multiple headphones.  In tests six 400 Ohm headphones were powered with no loss of level (a number of channels can be specified with order or retro-fitted) – and has overall power output of over 200mW RMS into 600R.


Outputs for each channel appear on both the front and rear of the unit, and are able to drive long audio lines to remote headphone outlets such as in vocal booths or over-dub rooms. Users can select from the four inputs (A, B, C and D) to hear A and B, or C and D as stereo, and A, B, C or D as mono. This means you can send two different submixes to the HeadLite from the mixer aux-outs to suit two different purposes. For example, the drummer and the singer might well need to hear different balances in their headphone feeds.

HeadLite III B offers excellent signal to noise ratios, low cross talk, very low distortion and a bass response that is flat well under 20Hz. The unit’s frequency response (-0.5dB at 3hz to 35kHz) is substantially flatter (within 0.1dB over the 22Hz to 22kHz band) than its predecessor. Because of the design of the amplifier’s output stage, its high frequency response does not suffer significantly, even down very long lines.

HeadLite III B delivers all a recording professional needs in a rugged and reliable package that will last for many years.
