Product Details (For Working Units Only)

The HA-6A Headphone/Monitor Amplifier is a unique combination of a headphone amp and a conventional power amp. This combination of functions can save the expense of an extra power amp in many recording studios.

The HA-6A is basically an economical 20 watt per channel stereo amplifier. Unlike a conventional power amp, however, it has six headphone outputs (stereo phone jacks) on the front panel, each with an associated volume control. When used for overdubbing, rehearsal, or in libraries and educational centers, this provides more than adequate volume for all headphones, allowing up to six people to set their own volume level. In the studio, when overdubbing is complete and the musicians remove their headphones, the HA-6A can power the recorded playback through either (or both) of two sets of passive studio monitor speakers, selected by pressing front panel pushbuttons. Without the HA6A, a separate amp would be needed for the studio speakers.

The HA-6A also features a convenient input level control on the left side of the front panel. A pair of yellow LED's - one for each channel - light up whenever signal is present (threshold -28 dBu). Another pair of red LED’s show an overload condition in either channel.

The Furman HA-6A's 20 watts-per-channel make it ideal as a low distortion headphone driver for the most critical listening situations. While most headphone amps provide half a watt or less per headphone channel, the HA-6A’s higher power can drive headphones of any impedance to their full rated listening level, and do so with minimal noise and distortion. Its power capacity is also just right for small near field monitor speakers used in most recording studios as a comparison with the main control room monitors - it can power them without overpowering them. On the studio floor, a set of small monitor speakers driven by the HA-6A can make a session progress more efficiently by giving the musicians a chance to hear a playback without needing to disconnect themselves from their equipment and walk into the control room. The HA-6A utilizes an efficient toroidal power transformer for low noise operation and low magnetic leakage, as required in a studio environment. It is fully protected against thermal overload, and it can withstand a short circuit on any or all outputs for an indefinite time without damage.
