My NAD C272 C has got a 2 Prong AC Input cable. When it's on I get a high pitch Noise how do I place a Earth Lead to this amp to get rid of the Ground Loop Him.
It's problem come on due to a fault on the speakers or wiring or connections especially shorts!
Clear that and it should come back on. If not then you have a fault in the main power amp section.
SOURCE: I think the amplifier protection circuitry has
Check the audio amplifier IC maybe are damaged and need to be replaced
SOURCE: I have a Tevion 7.1
The protect indication is due to a overload on the power amplifier unit. So you need to check the speakers to see that they are not shorted. remove all the speaker lines and switch on.
if there is a processor reset, power off the set and switch on while holding the selector/standy by switch. if not there is damage in the output within the amplifier.

My Jamo AVR793 works only in analog mode like pure audio and Direct Audio mode. It doesn't output any sound from any digital input and digital audio mode. Pls give me suggestion.
