Need advice on a faulty c audio ra3001!!

when you say 'bi-amp' do you mean 'stereo' (2 channel) or bridged (mono) ?
.
the mode switch may be broken, 1 set of contacts just works the mode LED, the other set does the linking.
Hi,

I've not fully tested yet. Will hopefully get some proper tests on it soon.

When I say Bi-amp, I mean 1 channel is HF and the other LF.

Interestingly the reported fault from the seller was that switch being stuck. Will defo be my first area of looking at.

I will be back on here when I've got more of an idea of what's going on.
