We have a retail shop - 4 audio zones. In our Primary room we have 4 JBL Pro Pendents. It's been working fine. Lately and NOT consistently, the audio will go from 70 to 0 in a slow fade, like someone is turning an Audio Volume dial. When it's turned back up to 80+, you can faintly hear the audio, yet distorted. We then try an audio all off - system all off - system all on and most of the times it doesn't come back. Low and behold 5 hours later, it will kick on and work fine.
All other zones no issues.
I'm not sure how C4 Amps act if they are in protection mode?
Anyone have this experience?
