Possible Cause
The cable connections are not tight, the con-
nectors are dirty or a cable is defective.
A record player has been connected to a line
level input of the preamplifier without using a
phono preamplifier.
An audio source with standard line level out-
put (example: CD player) is connected to the
power amplifier direct input "INPUT" (5).
One speaker pair is connected in bi-wiring,
but not both speaker outputs (SPEAKER A and
B) are activated on the front panel
See section "Net frequency noise"
in the chapter "Tips".
TECHNICAL SPECIFICATIONS
