Description

GS-HA010 is a portable, belt pack style single channel headphone amplifier. Audio input is via XLR with a loop through XLR output. Two headphone sockets are offered, 1 on 6.35mm and the other on 3.5mm. These are wired tip & sleeve to allow connection of regular stereo headphones (with audio on both ears) or a single ear piece. There is a volume control for adjusting level to 32 - 1000 Ohm impedance headphones.

Power is via a 9V PP3 battery (> 18 hours use) or via external DC power. There is an on/off switch and a low power LED light. Glensound belt pack cases are very rugged to withstand the rigours of portable use. There are loop anchor points on each of the front corners for shoulder straps or tying down, and there is a belt clip.
