Is there too much hum or hiss coming out of your speakers? If you put your ear right next to the tweeter
of your speaker, you should barely be able to hear any hiss in normal conditions, depending on amps. If the
noise is easily heard at a distance, try putting your source on mute, or pause. If this eliminates the noise, it’s
inherent in the source. If the noise is still there when the preamplifier is muted, try disconnecting the inputs to
the amplifier. If the noise is still there when the inputs are disconnected, and the inputs are shorted with shorting
plugs, then your amplifier may need some servicing. If the noise is not there when the inputs are disconnected,
try putting a cheater plug (ground isolator) on one or all components in order to eliminate a ground loop issue.
NOTE: We only recommend using a ground isolator for trouble shooting purposes, and should be removed after
the problem has been found. 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.
Where possible, use the Toslink inputs. Because of the optical transmission, there isn’t any audio connection
path to ground between components, and the possibility of a ground loop should disappear.
