TDA7492 Digital Audio Amplifier Board 2x50W
Have a 27v 2.4Amp power supply. Would that exceed the powers required by this board? Will it work or will it damage it?
Going by the manufactures specs 27V will be too much for this amplifier and I can not recommend going above 26V.

Basic wiring question; I get a full-volume buzz from my speakers until I have the input plugged into my 3.5 jack. Is there a way around this? Also wired a 500k pot (had it on hand) and get the buzz until the volume is about half way up.

How would you go about using RCA cables as inputs? What parts would I need and how would I wire it? I don't see any switches - how is volume controlled and the board turned on? If it's receiving power, it's on?

Will this run good on a 12 volt power supply? Also I am looking for something like this that has Bluetooth built in? What do you have that will work for a volume control nob with on off built in?
Regarding voltage supply, I would use a p/n 320-6546 to step up the 12v supply to a more appropriate voltage based on your impedance load (see product description above for voltages). I've used that voltage converter to step up to 24v from a 12v SLA battery and power a Lepai p/n 310-298 amp (with built in bluetooth), and it works great.

How can i run in mono this amp for a 4ohm load speaker ? Can it give 100w in mono?
The amp can run at 4 ohms into a channel and it will give you a bit more than 50 watts but it is not bridgeable. only the inputs can be paralleled for dual mono setup.

Can the amp handel the signal in as a high level, like an amplified source? Should the level line input be more in lign with a mA source, like an rca type?
This amplifier cannot handle a high level input. It needs a line level such as an RCA level input.
