I've got some contact cleaner out in my truck. I had an SI with a couple channels out, similar to what you describe. Most of the multiroom audio companies don't. I wouldn't have found it if it were not for the test rig Mac made me make a couple of years ago. My guess is that Niles doesn't release schematics. If that's ok I would suspect an input board problem. You would think there would be an F1 but who knows.
Take a look at the SI channel; three turn-on modes: music sense, voltage trigger and manual; binding posts spaced to Niles SI owner's manual.

Ooooh yaaa, that works for me I'll keep poking around.
Assuming you have all the bridge and dip switches in their proper location. The only connections to the input board are a 3 wire power connector at each end and 12 two wire outputs to the amps. A quick look and I could not find one.
What are the odds of that. All six bridging switches were bad.

I've got some contact cleaner out in my truck.
One or two, but all six??? Ended up soldering in some jumpers to bypass them.
I swapped channel 1 and 2 molex connectors at the amp board from the input board and got sound out of amp channel 1 so the amp is fine. If that's ok I would suspect an input board problem.
What voltage would you expect to see when probing Vcc and Vee 4 and 8?
