6.6 Problem: Hiss
Unplug the amplifi er 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 fl oor low, operate the primary signal source at full level,
without clipping.
Avoid boosting the signal further between the source and the amplifi er.
6.7 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 amplifi er and check each device in the signal path by reducing
its gain or by unplugging it.
