I have several, what I thought to be, simple systems in three different homes that continute to haunt me.

11 rooms of music (2 speakers, Russound impeadance matching volume controls, in each room)

Russound speaker connector blocks (1 for each amplifier - 2 total)

2 Audio Source AMP300 150w amps (1 for 6 rooms and one for 5 rooms)

1 1x4 CE Labs Amplified Audio Distribution module

Harman Kardon HK3385 Stereo Receiver.

Now, I have the Amps connected via r/w cables to the CE Labs module (out)
and I have the receiver (pre-amp out) connected to the CE Labs module (in). The same problem is occuring in each home at any givem time. One of the amps the left or right channel will stop working or the amp will shut off all together. I have checked rverything in the system at least 10 times.

I was told that possibly the receiver cant feed the amps and is losong the siginal (so I put in the CE labs audio module) Still did'nt fix the problem.

Does anyone have any suggestion on this and any future systems?

If the amps are shutting down, I would guess your total impedance is too low.

Do the Russound VC's have controls on them to set the impedance? If so, how are they set?
