Can I use my PowerStage 100s or PowerStage 700 in dual mono?
Yes, but it is different for each of these models
PowerStage 100s: Plug your mono signal to input 1. This signal will appear in Speaker Out 1 as well as Speaker Out 2. If you are using only 1 cabinet, use Speaker Out 1.
PowerStage 700: In the PowerStage 700, the signal coming in to the Left and Right Inputs come out of their respective outputs.
For dual-mono operation, a Y-cable must be used to connect both inputs to a mono effects box/pedal board.
For straight mono operation, either left or right channel can be used. The unused channel can always act as a back-up. If you have connected the left channel speaker out, be sure to use the left input channel, and vice-versa.
