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

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 .
