Troubleshooting
Hum on analogue input
There is no reason for the 568 to produce hum on the analogue
input.
❍ Check the source equipment. Disconnect each source in turn.
❍ If the hum originates from a ground loop, an antenna or cable
supply may be the cause. In this case an antenna-lead isolator
should be fitted.
❍ If the 568 seems to be the cause of hum consult your dealer.
There is radio interference
The 568 is a digital audio and computing device which has been
designed to very high standards of electromagnetic
compatibility.
If this equipment does cause or suffer from interference to/from
radio or television reception then the following measures should
be tried:
❍ Reorient the receiving aerial (or antenna) or route the antenna
cable of the receiver as far as possible from the 568 and its
cabling.
❍ Ensure that the receiver uses well-screened antenna cable.
❍ Relocate the receiver with respect to the 568.
❍ Connect the receiver and this product to different AC outlets.
❍ If the problem persists contact your dealer.
