When I spoke to Axiom about it they said that there's enough protection built in that it wouldn't be an issue. Plus they said that if when the Amp is powered up: Button in the back, then front switch....then a clicking should with all LEDs Blue...it means it's fine and working.
My reason for posting here is to find out if someone possibly had do do some configuration with the Yamaha AV rec... I wasn't holding that info back for any reason.

What you were told is at variance with what Axiom told Gene when evaluating one of those Axiom Class D amps. He blew up two in the evaluation and one failure was incendiary. According to Gene they told him they could not provide protection due to the very high frequencies in the power supply.
I'm sorry but this is where the customer has to do due diligence to avoid a bad purchase.
Axiom is a speaker company and a relatively small one. Their speakers are not held in high regard to state it mildly.
So this company decides to design and produce very difficult to design class D amps. Not only that they make it run at a higher frequency than anything else. It is hardly surprising if the end result is problematic.
Gene found that these amps blow up when not connected to a load and as soon as there is even a brief short in a speaker lead. This is not acceptable performance.
I agree that the user manual makes no reference to these amps vulnerabilities. Not only should they disclose this, unless there has been a reliable revision, but there should probably also be some sort of warning to the effect that under certain circumstances this unit can become an incendiary device. After purchase the owner is advised to contact his insurance agent, as increased rates for home owner hazard insurance may apply.
As you might gather this company is well up my list of non recommended companies.
