General Observations:
1)Snaps from Cable are easily audible from 10-15 feet away with the volume set to ~57
2)With source (Scientific Atlanta and Pioneer) turned off, there are no snaps from any speakers with any input and any DSP setting
3)Snaps when input is set to DVD are much lower than the snaps heard when the input is set to cable.
4)Pops also heard from CD input setting as well as tuner.
5)Tried power on/off. Reloading firmware, did not affect results of tests.
6)Also hear “snap” intermittently when changing sources, changing DSP modes, and selecting compression levels for Dolby Digital sources. “Snap” always comes from Center or Left Rear Surround channel.
7)“Snap” also randomly occurs when changing cable channels from a channel that is DD 5.1 to a channel which is 2-Channel.
