More Posted September 10, 2019 Report Share Posted September 10, 2019 I just realized this a "minute ago"... I brought my home system out for an event that I do once a year and in hindsight messed up . I changed out my normal sub amp setup from 2x ep4000 running bridged at 8 ohm (running 4x 4ohm loads in dual series) yes channel B was always muted/left to do bridged mode. I changed that to 4x EP4000's running one 4ohm bridged load per amp. Or so I thought. When i disassembled that rack to give an amp to a friend, I noticed the the dip switches on all 4 were configured to accept and output stereo! Not parallel inputs so that I could run one xlr to each A channel of the 4 amps from 4 channels of a dcx2496, Ugh I screwed up and didn't use the dip switches to flip phase on channel B. I had changed my 2 bridged amps dip switches to the stereo amps settings instead of making all 4 bridged amps, but wired them in proper phase red and red. I have wired like 3 things out of phase in my life.... mmmm Grrrrrrr. So my question is: What effect does using channel A's positive along with using a maximally attenuated channel B's red/hot side as the negative without sending a signal to "B" have on an amp?
