Audio Problems - Meridian 565 Installation Manual

Audio problems

Hum on analogue input
There is no reason for the 565 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 which case an antenna-lead
isolator should be fitted.
If the 565 seems to be the cause of hum consult your dealer.
Poor sound quality
Poor sound quality will usually result from driving an analogue
input too hard.
Turn down the analogue input level.
To optimise this use the ADC Check procedure; see ADC
Check, page 43.
There is radio interference
The 565 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 565 and its
cabling.
Ensure that the receiver uses well-screened antenna cable.
Relocate the receiver with respect to the 565.
Connect the receiver and this product to different AC outlets.
If the problem persists contact you dealer.
