Powered from either an external power supply of between 9VDC to 18VDC, or from 48V phantom power. Three looped ¼” input / through sockets are provided, two on the front and one on the rear. 20dB and 40dB pads, and earth lift. For maximum versatility we have also included our CabSim circuit, which can be switched off via the front panel switch.
 
The CabSim replicates the frequency response of a Celestion filled quad box. We also included the DRIVE control to replicate power amp compression and speaker breakup. For best results adjust the DRIVE control until just around “edge of breakup” and tweak to taste
