Music cuts out using Rotel amp and Sonos connect

I’m using a 100watt/channel Rotel amp to power B&W ceiling speakers. Occasionally the music cuts out at low volumes and randomly comes back on. I’ve checked all of connections on the professionally installed rack and consulted with Rotel yet nothing seems to work.

The Rotel is RMB1512 digital amp, there is no volume control on it. By 80% volume level on the Sonos connect side I assume you mean adjust the volume limit to 80%?

Yes, but since the Rotel has no volume control being a power amplifier, 80% will be too loud. Is it possible that there is some signal auto sensing and going to standby happening with the Rotel at low signal levels?

PS: what happens if the auto turn off/signal sense switch at the back of the Rotel is set to off?

In my case, I had to increase the Denon 3700H receiver speaker levels by 9dbs each and turn the adjusting screws of the Rotel a quarter clock-wise from their off position. It doesn’t go into sleep anymore.

If not going into sleep mode is acceptable, can that not be achieved by just toggling the signal sense switch to OFF? What the OP has done, accepting the need to do power cycling of the Rotel manually whenever needed as the trade-off.

No because then your amp uses more power even when you do not use it. It should not go to sleep even at lower volumes. I actually gave up on adjusting the sensitivity and just bought a signal gain inline amp and fed it back to an unused channel on the amp.
