Furman HA6AB Headphone Monitor Amplifier

The HA-6AB 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-6AB is basically an economical 20-watt per Channel Stereo amplifier. Unlike a conventional power amp, however, it has 6 headphone outputs (stereo phone jacks) on the front panel, each with an associated volume control. When used for overdubbing or rehearsal, this provides more than adequate loudness in all Headphones (even older low-impedance models), and allows each musician to set his or her own comfortable volume level. When the overdubbing is complete and the musicians remove their headphones, the HA-6A can power the tape playback through either (or both) of 2 sets of studio monitor speakers, selected by pressing front panel pushbuttons. Without the HA-6AB, a separate amp would be needed for the studio speakers.
The HA-6AB also features a convenient Input level control on the left side of the front panel. A pair of yellow LEDs one for each channel-light up whenever signal is present (threshold -28 dBu). Another pair of red LEDs show an overload condition in either channel.
