Description
The GS-HA013 like other units in this range is small, robust and economical. It provides 1 off headphone amplifier in a compact format. It builds on the successful GS-HA001 and adds switches to allow each input to be routed to the left ear, right ear, or both. 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.
