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 before switching off the units con-
nected.
1) Before switching on the amplifier for the first
time, set all volume controls (2) to zero so
that the volume will not be too high. Before
switching on the amplifier, always make sure
that the selector switches OPERATING
MODE (10) and BRIDGE MODE (11) have
been set to the correct position,
ter 5, step 3.
2) Use the POWER switch (4) to switch the
amplifier on and off. After switching on, the
yellow power LED ON (3) will light up. In addi-
tion, the red LED PROTECT will light up for a
few seconds. During this time, the amplifier
will be muted to prevent any switching noise
(switch-on delay). When the bridge mode has
been activated, the green LED BRIDGE will
light up to indicate this mode.
3) Use the volume controls (2) to adjust the
desired volume. The green LED SIGNAL (1)
will light up when a certain volume has been
reached. In case of overload of a channel, 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.
7 Protective Circuit
The protective circuit will prevent damage to the
speakers and to the amplifier. When the protec-
tive circuit has been activated, the speakers will
be electrically separated from the amplifier. The
red LED PROECT (3) will light up
1. for approx. 3 seconds after switching on
(switch-on delay)
2. in case of a short circuit at a speaker output
(9 or 12)
3. in case of a DC voltage at a speaker output
4. in case of overload of the amplifier
When the red LED PROTECT lights up during
operation or when it is not extinguished after
switching on, always switch off the amplifier and
eliminate the fault.
In case of overheating, the red LED OVER-
HEAT will light up. Switch off the amplifier and let
it cool down. To continue operation, reduce the
output power (turn back the volume control) or
improve the ventilation of the amplifier (e. g.
insert a ventilation unit into the rack).
