5.2 Signal source

As a signal source, connect a unit with a line
output (preamplifier, mixer, PA mixing am-
plifier, etc .) to the XLR input (13) or to the
terminal strip (14) .

5.3 Additional amplifier

If the number of the required speakers is
higher than the number admissible for the
amplifier, an addition al amplifier will be re-
quired . Connect the input of the additional
amplifier to the jack LINE OUT (11) . The out-
put level of the jack depends on the MASTER
VOLUME control (2), however, not on the
tone controls BASS and TREBLE (1) .
5.4 Power supply and
emergency power supply
For continued operation of the amplifier after
a possible mains failure, connect a 24 V emer-
gency power supply unit (e . g . MONACOR
PA-24ESP) to the terminal strip DC INPUT (9) .
To facilitate handling, the terminal strip can be
removed from its plug-in connection .
Finally connect the supplied mains cable
to the mains jack (6) first and then to a mains
socket (230 V/ 50 Hz) .
Notes:
1 . With a voltage of 24 V applied, the amplifier will
be in operation immediately and the LED ON (4)
will light up . It will not be possible to switch off
the amplifier with the POWER switch (5) .
2 . With emergency power supply, the amplifier
will deliver less power than with mains supply .

6 Operation
1) Prior to switching on the amplifier for the
first time, set the MASTER VOLUME con-
trol (2) to position "0" for the time being .
2) Switch on the amplifier with the POWER
switch (5) . The LED ON (4) will light up .
With an emergency power supply
connected, the LED ON will light perma-
nently and the amplifier will always be in
operation . With the POWER switch, it will
be only possible to switch between mains
supply and emergency power supply in
this case . For normal operation, set the
POWER switch to position "On" . In case of
mains failure, the amplifier will automat-
ically switch to emergency power supply .
3) Set the MASTER VOLUME control (2) to the
desired volume . The 5-step LED VU-meter
(3) will show the output level .
4) Adjust the tone controls BASS and TREBLE
(1) to optimum sound . Readjust the vol-
ume with the MASTER VOLUME control,
if required .
5) In case of unwanted low-frequency inter-
ference (e . g . hum noise), press the button
LOW CUT (12) .
