Disconnect your RCA output leads and if you have XLR output leads disconnect them too. Place the leads of your multi meter on the RCA output connectors and measure for DC volts. Then do the same to the XLR output connectors if you have them. On the XLR connectors measure Pin 2 (+ signal) and Pin 1 (Signal Grd) then Pin 3 (- signal) and Pin1. Ideally it should be O volts or a few millivolts. Anything larger may damage to your speakers particularly if your amp is DC coupled.
How to check my preamp for a DC leak
Hello,
After posting in a previous thread about my amp cutting out every now and then, it was suggested to me that mu preamp may have a DC leak.
I bought myself a multimeter, but I'm not sure how to check for a DC leak. Would anyone be able to tell me where the leads should be connected, and whether I need signal coming into the pre to test for this?
