disconnecting the inputs to the integrated amplifier. If the noise is still there when
the inputs are disconnected, then your amplifier may need service. If the noise is not
there when the inputs are disconnected, try putting a cheater plug (ground isolator)
on one component at a time in order to locate the source of the ground loop. Once
the source is located you can contact the manufacturer for further information
regarding a solution. NOTE: We only recommend using a ground isolator for trouble
shooting purposes, and should be removed after the problem has been found and
resolved. Having the ground of any unit disconnected can potentially create a
dangerous situation.
An easy way to locate a noisy component is to replicate the problem then
start disconnecting components one at a time, starting with a source. Digital cable
boxes and satellite receivers are notorious for making ground loop hum. This is
normally caused by the potential difference on the input wire (shield side) for either
of the boxes when referenced to ground. If this is the case in your system, the
installation of an isolating transformer would be the easiest solution and are
normally readily available at your local electronics parts store. A better solution is a
power strip with grounded and surge protected F-connectors that you can pass a
signal through.
