I own a Pioneer DEH-6400. Everytime I lower the volume all the way down to 0 it generates a "pop" on the Left Rear channel both on the hi level and lo level outputs. This also happens when i switch sources and use the Easy EQ button. It is only one pop per button press not a constant popping. It is very annoying and you can imagine what a simple pop sounds like when its run through 1200 watts of power. I tested everything. The patch cables, power connections etc. and nothing. My co-worker suggested it might be the internal power supply. Are there any other suggestions? Thanks in advance.
