Bridged amp operation and parallel inputs brief description
Ok, here's a brief tutorial on bridged operation...The signal goes into the channel 1 input and through the first amp stage... the output from channel 1 is inverted and then sent into the channel 2 input (internally) and is then sent through the #2 channel to the outputs where 1+ and 2+ or both red output terminals become the outputs...(remember to observe polarity... channel 1/A is typically the + channel) if you were to use the #2 inputs for paralleling the signal would be inverted...the second channel volume control also should be fully counterclockwise (off), and the parallel inputs off...the reason for this is that the parallel inputs switch allows you to take a signal into the #1 input and drive the #2 channel as well, (as in a mono sub signal feeding a pair of 4 ohm subs on a single amp.. you can't bridge an amp under 4 ohms but dual 4 ohm mono is acheivable this way...) so, if you engage it when in the bridged mode the signal will be sent inverted AND sent parallel to the same input in normal polarity...NOT GOOD!
Parallel inputs means that the same signal that is sent in on the XLR is available at the 1/4" input... that way the signal could be sent in via an XLR or 1/4" cable... so, that being the case, if you use a balanced 1/4" cable from the #1 channel input on the first amp to the 1/4 " input on the second amp (this would also work even IF you weren't using a bridged setup.. it could be fed to any amp, any channel whether in parallel, bridged, or stereo operation) you will be sending the signal that is coming in on the XLR input back out through the 1/4" input to the second amp...
DO NOT USE TS 1/4" cables use TRS 1/4" cables!
