2 Safety Notes
The unit corresponds to all relevant directives of the
EU and is therefore marked with .
WARNING
The unit uses dangerous mains
voltage . Leave servicing to skilled
personnel only and do not insert
anything into the vents! Inexpert
handling or modification of the unit may result
in electric shock .
During operation there is a hazard of contact with
a voltage of up to 100 V at the speaker connec-
tions (23, 25) . Never use the amplifier without the
protective cover (22) .
Always switch of the PA system when making or
changing any connections .
•
The unit is suitable for indoor use only . Protect
it against dripping water and splash water, high
air humidity and heat (admissible ambient tem-
perature range 0 – 40 °C) .
•
Do not place any vessels filled with liquid, e . g .
drinking glasses, on the unit .
•
The heat being generated inside the unit must
be carried off by air circulation . Therefore, the
air vents at the housing must not be covered .
•
Immediately disconnect the mains plug from the
mains socket if
1 . the unit or the mains cable is visibly damaged,
2 . a defect might have occurred after the unit
was dropped or suffered a similar accident,
3 . malfunctions occur .
In any case the unit must be repaired by skilled
personnel .
•
Never pull the mains cable to disconnect the
mains plug from the mains socket, always seize
the plug .
•
For cleaning only use a dry, soft cloth; never use
chemicals or water .
•
No guarantee claims for the unit and no liability
for any resulting personal damage or material
damage will be accepted if the unit is used for
other purposes than originally intended, if it is
not correctly connected or operated, or if it is
not repaired in an expert way .
If the unit is to be put out of operation
definitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment .
3 Applications and Accessories
The amplifier is especially designed for application
in 100 V PA systems . 100 V outputs for six PA zones
are available, the volume of which can be adjusted
individually . Via three inputs with individually
adjustable priority, microphones or units with line
output may be connected . Two further line inputs
complete the connecting possibilities .
