How do I use the THRU outputs on PCH?
The THRU outputs are 1/4″ unbalanced, Left and Right, TS outputs. Use them to pass your buffered input sources to amplifiers, effects, or other devices.
When connecting a stereo source to both Left and Right Ins, keep the SUM switch disengaged for stereo THRU output. Or, engage SUM to merge the stereo input to a mono signal fed to both THRU Outs.
- When connecting to the Left In only, its mono signal is routed to both THRU Outs, unaffected by the SUM switch.
- The XLR Outs are unaffected by the SUM switch.
