5.3 Problem: Hiss / Noise
Unplug the amplifier input to confirm that the hiss is coming from the
source or from a device upstream. Erratic or popping noises indicate an
electronic fault in the offending unit.
To keep the noise floor low, operate the primary signal source at full level
without clipping.
Avoid boosting the signal further between the source and the amplifier.
5.4 Problem: Squeals and Feedback
Microphone feedback should be eliminated with mixer controls. If noise
continues to build up with no microphone gain, there is a serious fault
in the signal processors or cables. Working in succession from the signal
source towards the amplifier and check each device in the signal path by
reducing its gain or by unplugging it.
