6 Operation
Hint: To prevent switching noise, switch on the units
connected to the amplifier before switching on the
amplifier . After operation, switch off the amplifier be-
fore switching off the units connected .
1) Before switching on the amplifier for the first
time, set the two volume controls (2) to zero
to make sure that the volume will not be
too high .
2) Use the POWER switch (5) to switch the am-
plifier on and off . The power LED ON (4) will
light up a few seconds after switching on .
This delay will prevent any switching noise .
3) Use the volume controls (2) to adjust the de-
sired volume . In case of overload of a chan-
nel, the corresponding red LED CLIP (1) will
light up . Turn back the control accordingly .
CAUTION Never adjust a very high vol-
ume . Permanent high volumes
may damage your hearing!
Your ear will get accustomed
to high volumes which do not seem to be
that high after some time . Therefore, do not
further increase a high volume after getting
used to it .
4) In case of malfunction (overheating of am-
plifier or short circuit at a speaker terminal),
the LED PROTECT (3) will light up and the
amplifier will be muted . In this case, switch
off the amplifier and consult skilled personnel
for fault elimination .
