5.6 Problem: Hiss
• Unplug the amplifier input to check 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.
5.7 Problem: Squeals and Feedback
• Microphone feedback must be eliminated by the 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 stages from the signal source
towards the amplifier and check each device in the signal path by reduc-
ing its gain or by unplugging it
