As the manual states - you must flip the switch to "bridge" and use the left speaker output. However, I was playing around with the switch the other day and and switched it to stereo and there was no difference
Is there another way that I dont know about to bridge the amp?
Using the switch allows the amp to be used in a single mono set up , with one INPUT, the bridge is actually on the OUTPUT side with L+ve and Right -Ve .
When using the switch it allows both inputs to be used, but will mono the signal.
Thanks for the insight. But to run the amp mono, which speaker output do I use? Just the left channel? Or use + for left ch and - from right ch, like most amps?
