Hi All,

When play content, speaker volume unstable too loud and too soft. What I can do for this issue?

System:
-Barco 2 series with Dolby IMS2000
-Dolby CP650

Izit CP650 out of control cause this problem?

Does the issue occur on all channels, or only one channel, like center?

Can you run pink noise on the CP650 and still hear the problem?

Are you sure that what you are noticing isn't just the dynamic of a digital soundtrack?

Probably bad encoder (fader) in the CP-650. This happens.
