When I use one of the multichannel inputs the sound is very loud and cannot be turned down. The Display shows “Theater Bypass” instead of the volume level.

Go back to the Setup menu and change the Theater Bypass setting to “No.” When one of the Multichannel inputs is set to Bypass, it should never be connected directly to a source component (CD, DVD, SACD, HD disc player, etc.).

Although your P 7 will sound spectacular when you fi rst turn it on, you will come to appreciate it even more as your listening hours accumulate. You’ll discover additional musical details you may not have known were present.
