Well I got my Audison AV5.1k amp up and running. I don't have an O scope or access to one so I tried to set my gains with a DMM. Now the 2*75w and 2*140w channels worked out to the watts times ohm load square route calculations but I had an issue with the sub channel. It is a 600 watt at 4 ohm mono channel. Or 1000 at 2 ohm.
I disconnected the speaker wires and tested. It should have been 48.8 volts but I was getting closer to 90 volts unless the gain was all the way off. Is there something I am missing with this being a mono channel or?????
