Hi

Without any warning and ok last switched on one of my rear 3200 speakers has suddenly produced a very loud constant buzz.

l have done all the obvious things swapped speakers over changed left to right etc. but buzz remains with that speaker.

All SpeakerLink connected.

Also if l switch on system in direct mode ie the 3200 though on but in standby no buzz. Buzz only when all 5 speakers are fed a signal. Buzz still continues even if l go back into Direct mode. Can only stop by going back to standby and starting up in Direct mode.

Any thoughts apart from “something” has suddenly failed!?
