I've noticed that the Peak level LED on the front display flickers on and off when in CD mode. I'm using my Toshiba SD210E DVD player connected to the amplifier's analogue CD input. If I switch to DVD mode, which is the same player connected by digital coaxial, then no flickering. Also in CD mode pressing the ATT (Attenuate) button on the remote reduces the volume slightly and again the light stops flickering. Anyone have any ideas? Thanks.
