5) Output

The output signal is adjusted per default to 100 V. Optionally, an adjustment to
50 V or 70 V can be made. For this all that is needed is that a jumper be sol-
dered onto the backplane of the DVS-21 system. The signal is switched over
the closed circuit contact of relay 1.

6) Disaster Switch

In the case of a disruption, depending on the system, one or multiple amplifi-

ers can be used as emergency amplifiers. One amplifier can assume the
disaster function for up to 6 amplifiers. In the case of a disruption the dam-
age relay (relay 2) and the output relay (relay 1) of the defective V100 drop
out. The loudspeaker circuit of the failed amplifier is connected with the out-
put of the disaster amplifier over the normally closed contact of relay 1. Allo-
cation of the disaster amplifier is done using solder bridges on the back-
plane.

7) Wire Breakage and Short-Circuit Monitoring

Output voltage and current in the loudspeaker line are measured for wire

breakage and short-circuit monitoring. An error message is issued if pro-
grammed limit values are underrun or exceeded. A TG01 and a 4LSL are
required for more precise monitoring of impedance in individual loudspeaker
circuits.
