Question about Audio Players & Recorders
There has been a sudden loss of output to the main/front speakers which are driven by an external amp the signal of which comes from the Pre-Out. The external amp is fine, and the receiver is otherwise OK. If have the receiver set itself up automatically using the microphone, it has to increase the output to the main/front speakers by the max (10db) and decrease the surround and center speakers by the max (10 db) but then the mains are bass-heavy and muddy and still the output is low. Previously everything worked fine and all speakers balanced out to within 2 db of each other. I cannot correct this with any of the settings. Is this a setup issue or does this represent a component failure?

Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd

The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.

SOURCE: Speaker output
Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.

It is possible then that the root cause may not be electrical, but acoustic if you're noticing the issue from your listening position.
If you can run a channel test signal identically one channel at a time by positioning your meter less than a foot away and exactly the same distance with each speaker and the level differs by more than 1/2dB, then it's not the acoustics.
