I read this several times and still it's clear as mud. Probably a poorly written manual, it doesn't say bridged mode is for mono only. Well, if you “combine both channels” (first paragraph) and put the input signal into the “left channel only” (fourth paragraph), I’d say it goes without saying that you end up with a mono amp. As far as how to accomplish the bridging, it says to: * Activate the bridged mode switch * Connect the speaker to the two red terminals only, right for (+) and left for (-) * Use the left-channel input for the signal. Seems straightforward to me, not sure why you think it’s “poorly written.” Regards, Wayne A. Pflughaupt
