I just purchased a Marantz PM6006 amplifier, and noticed that there is a very odd issue with the source direct button. I have a very simple setup. This being a Marantz CD6006 compact disc player, plugged into the PM6006 receiver via RCA cables into the CD port. I also have a turntable plugged into the Phono port. Now, I know when the source direct button is on, it's bypassing the circuitry and sound shaping that the amplifier has to offer, in which it disables tone controls and loudness. When I have the button on, it sounds fine. However, when I turn it off, the volume increases significantly, and it's all distorted and inaudible. Sort of like everything is going through an echo chamber. Even if I have volume all the way down, and then turn off source direct, the volume is boosted, as well as all the distortion and weird sounds. The same thing happens when I use the turntable. I even tried connecting the CD player to the amplifier via an optical cable to bypass the DAC, and it produces the same problem. Is there something wrong with the amplifier, or is there something I'm not doing correctly. Anyone else experience this?
