The GSGC25 is a very simple ISDN unit that contains two G.722/G.711 codecs. Each of the three mic/line inputs can be fed with 12v phantom power.
 
Calls can be made using the keypad and levels monitored with a 7-segment LED display.
 
Comprehensive headphone monitoring is available from four sources, each with its own level control. The headphone amp output is on three front panel A/B gauge headphone jack sockets, one wired to only the left channel of the headphone amp, one wired only to the right channel & one wired to both. A record output (on a rear panel ‘bantam’ jack) is a mix of the output of the GSGC25’s mixer and the return programme cue line.
 
The GSGC25 can be powered from 2 ‘D’ cells (approximate battery life of 4 hours) or an external plug-top power supply. 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.
