G-Lab GSC-3 Firmware Instructions

Firmware 2.25 version for GSC-3 and GSC-2

New functions:
- added two SWITCH outputs working modes for amp controlling,
Amp controlling
Controller enables the SWITCH outputs to work on SF1 – latching type mode, SF2 – pulse mode and
SF3 – momentary switch mode or SF-4 and SF5 - mixed modes (see SWITCH button settings, footswitch
No 8). Mostly used mode is the SF1 - latching type mode. In this mode the indicators SWITCH 1 to 4 lit
what means contact short-circuit of corresponding relay. Other modes are applied in selected amp models
for which is required other functionality of outputs. In case of controlling the amp with momentary switch
input (SF3 mode) the amp should have the switch which enables switching the functions in order to
synchronize the controller and the amp states.
