The Glensound GS-HA001 like other units in this range is small, robust and economical. It provides a 1 off headphone amplifier in a compact format.
A toggle switch turns the unit on/off and a bright blue LED indicates that the unit is on and flashes when the battery is getting low.
Audio input is on 2 XLRs normally feeding left & right channels of the headphone amp. A switch is provided to allow an unbalanced stereo signal input on just 1 off these XLRs to be feed to both channels of the headphone amp.
A phase reverse of the right ear facility is provided (operation by a small toggle switch).
2 off headphone jack connections are provided (in parallel) each connector is suitable for use with both A and B gauge jack plugs.
