My amplifier makes white noise, what should I do? - …

No. White noise is the name for a signal with equal power at all frequencies. What OP is experiencing is like white noise, in other words a broadband interference. If you were to swap the input to a portable device, and move the cable so that it goes directly from the phone/mp3 player to the speakers and avoids other cables, does the sound persist?

Secondly, noise is commonly referred to the input of an amplifier circuit. This allows the instant calculation of output noise by simply subtracting the dB figures. So an amplifier with an 'Equivalent Input Noise' (E IN) of -120dBu having a gain of 40dB will have an output noise of -80dBu (120 - 40).
White Noise Problem from Amp - Sound, Stage, and …

All electronics have noise. The question really is how loud above that noise can the piece get. That's called "signal to noise ratio" and guitar amps are not known for having a large s/n ratio. It gets worse the higher gain you have your amps set at as well So the question is do you have defective gear or just a amp that is normally noisy?

Audio Amplifier circuit with noise filtering Abstract This project gives an insight into the practical use of audio amplifier along with a noise filtering circuit. Any random signal given to input containing any noise can be filtered using the noise filtering circuit and then provided to the audio amplifier for amplification of the inputted signal.

Remember, he said only the noise appeared in his rear speakers. Let him respond to my post - see if it occurs on discrete 5.1 soundtracks or on prologic or other dsp modes. I get noise from my amplifier when I have a toslink cable as my only input. If I turn the gain on the amplifier to around -15dB I can hear noise. When at 0dB it is quite loud.
