output level.
One internal headphone amplifier is provided, with the output in parrallel on 2 front panel A or B guage jack
sockets. Two front panel pots control the level to the headphone amplifier of the output of the mixer and the

when an ISDN line is open.
The GSGC24A can be powered from 2 ‘D’ cells (approximate battery life of 4 hours) or an external plug top
psu. If it is being powered from the external supply and the supply fails the batteries will automatically take
over. A front panel LED shows when the GSGC25 is switched on and flashes to indicate when battery level is
low.
