A switch-on delay connects the loudspeakers to the loudspeaker output, when all
capacitors in the device are charged. Thus, a click in the loudspeakers during power
up is avoided.
The protective circuit responds to short circuit, output direct voltage and prevents
overheating.
Additionally, a headphone can be connected to the headphone jack on the front plate.
Initial operation
To ensure correct initial operation, please read these operating
instructions and the safety instructions through carefully before
using the appliance!
Before connecting the amplifier, turn it's power switch to the off
position and disconnect and turn off any other appliances that are
connected with it.
Repeat the above procedure when re-wiring.
Installing/setting-up
The amplifier can either be set-up on a flat surface or installed into a rack system.
To install into a rack screw onto the rack rail through the fastening holes on the front
plate of the amplifier. Due to it's heavy weight you should always install the amplifier
at the lowest point in the rack.
Take care not to place your amplifier in direct sunlight and protect it
from vibration, dust, heat, cold and moisture. Keep the appliance
away from strong transformers or motors.
The cooling fins on both sides of the amplifier must never be cov-
ered. If installed in a rack system always remove the rack covers
before operation!
Always operate the amplifier on a steady surface, and one that is
not heat sensitive and make sure it is upright and has enough air
circulating around it.
Carelessness in following these instructions could lead to the
appliance becoming damaged.
The amplifier is heavy so make sure that it is well mounted or on a
stabile surface to avoid unnecessary accidents.
Connection of signal in and outputs
This amplifier is equipped with symmetrical inputs with XLR and 6.3mm mono jack
bushings that accept unsymmetrical signals, too.

Having made this setting all further
adjustments are only made with the
volume control on the audio source.
When switching the system off start
with the amplifier mains switch POW-
ER (5) and only then the audio
sources.
Protective circuit
The protective circuit responds to short circuit, output direct voltage and overheating
This is indicated by the LEDs PROTECTION (3).
If one or both LEDs PROTECTION (3) are flashing, clear the cause of errors and than
press the RESET (6) key to continue with the operation.
Handling
• Never plug the power plug into a mains socket immediately after the appliance has
been taken from a cold to a warm environment. The condensation water that
develops may lead to the appliance malfunctioning.
Allow the appliance to reach room temperature before connecting it to the
power supply. Wait until the condensation water has evaporated.
• Never connect or disconnect power plugs with your hands wet.
• Never disconnect power plugs from the mains socket by pulling at the cable.
Always pull out the power plug, holding it at the contact surfaces provided for this
purpose.
• Always disconnect the power plug from the mains socket if the device is not going
to be used for long periods of time.
• To ensure adequate ventilation, the cooling fins on both sides of the amplifier must
never be covered. Apart from this, the air circulation may not be obstructed by
objects such as magazines, table cloths, curtains or similar. If installed in a rack sys-
tem always remove both rack covers during operation!
• For safety reasons, always disconnect the power plug from the mains socket dur-
ing thunderstorms.
• Do not listen to excessively loud music for long periods of time. This can damage
your hearing. This is especially the case when using headphones.
Servicing
Periodically check the technical safety of the amplifier, e.g. check for damage to the
power cable or the housing.
The setting up procedure should be
repeated for every re-wiring.
If you don't follow the instructions
step-by-step clicking sounds may
result that could damage the loud-
speakers.
