Tested and modified the TDA7492P Bluetooth Amplifier module

I have bought the new blue version of the popular TDA7492P module. Compared with the older red one, made some tests and measurements. As it was a bit noisy I have modified it by removing the gain jumpers to achieve a lower amplification level, so also the noise will not be amplified so badly.
