Question about Cambridge Audio Audio Players & Recorders
The first thing I would try is swapping the speaker wires on the back of the amp and see if the problem moves as well. Then you know what your speakers or speaker wire. If that's not the case, then try switching the left and right
from your sources and see if the problem follows. This should get you a pretty good idea of what's wrong

Yes, you are right. That's a protection feature to prevent burnouts. Typically it appears when your speakers are sucking up a lot of load from the amp. Please check your speaker impedance and the amps' output impedance and ensure the wiring are properly done. Some amps are soo sensitive that they may cut-off after certain level due to overload.

Looks like the fuse blown.. or the classic symptom of electrical fault inside the amp. 640A uses a sensitive protection circuit often ends up in this irritating situation. Normally, there is nothing much you can do, but just check your wall plug connection for Open Ground or Left & Neutral reversed issues. If the wall plug is free of error, then you should better contact CA technical support.

Switch the channel on the phono to isolate the problem within or outside of the amp.
