Support for the mains fuse

Always replace a blown fuse by one of the
same type .

Terminal strip for speakers to be switched
on all the time, i . e . for speakers not to be
switched on and off via the buttons ZONES
(7);

always observe chapter 5!

Line level input EM INPUT (screw terminals)
for important announcements

As soon as a signal is present at this input,
the signals of the inputs INPUT 2 to INPUT 5
(11, 19, 20, 21) and of the MP3 player will
be faded out .

Control MUTE LEVEL to adjust the level of
volume attenuation (0 – 30 dB) for the inputs
INPUT 2 to INPUT 5 (11, 19, 20, 21) and for
the MP3 player when an announcement is
made via the input MIC 1 (2)

6 .3 mm jacks (unbal .) of the inputs INPUT 2
and INPUT 3 for microphones; as an alter-
native to the XLR jacks (11) and the RCA
jacks (20)

RCA jacks of the inputs INPUT 2 and INPUT 3
to connect audio units with line level output
(MP3 / CD player, radio, tape deck etc .); as an
alternative to the microphone inputs (11, 19)

RCA jacks of the inputs INPUT 4 and INPUT 5
to connect audio units with line level output
(MP3 / CD player, radio, tape deck etc .)

Line level output OUTPUT for the mixed sig-
nal to connect, for example, an additional
amplifier if more speakers are required than
the PA-312DMP can handle

minal strip ZONES OUTPUT (10) – refer to
fig . 4 . The

maximum

load of the amplifier by

the speakers must not exceed

120 W

2 . Connect 70 V or 100 V speakers to be

switched on all the time to the terminals 70 V
or 100 V and COM of the terminal strip OUT-
PUT (16) – refer to fig . 5 or 6 . The

maximum

load of the amplifier by the speakers must not
exceed

120 W

3 . The connection methods 1 and 2 may be com-

bined if a total load of

120 W

is not exceeded

by the speakers connected .

4 . Connect a speaker or a speaker group with

a total impedance of at least 4 Ω to the ter-
minals “4-16 Ω” and “COM” of the terminal
strip OUTPUT (16) . The speaker is (the speak-
ers are) switched on all the time . Figures 7 to
10 show different methods to observe the
minimum impedance; however, there are also
other possibilities .

As a protection against contact, each speaker
terminal strip (10, 16) is provided with a trans-
parent cover . To connect the speakers, fold up
the corresponding cover .

WARNING

Always fold down the covers
of the speaker terminal strips
(10, 16) before operation . Dan-
gerous high voltage is present at

the terminals; avoid any contact . Risk of elec-
tric shock!

4.4 Infrared remote control

Power supply of the remote control (fig . 3) for

the MP3 player is provided by means of a 3 V

button cell . If the remote control is supplied with

the battery inserted, remove the protective film

(to protect the battery against discharge) from

the battery support: The remote control will then
be ready for operation . When you press a button
on the remote control, always point the remote
control at the amplifier . Make sure that there
are no obstacles between the amplifier and the
remote control .

If the remote control is not in use for a

longer period of time, always remove the bat-
tery to prevent damage due to battery leakage .

Replacing the battery

1) Push the latch of the battery support to the

right (arrow 1 in the figure below) and pull
out the support (arrow 2) .

2) Remove the discharged battery and insert

the new battery (3 V button cell of the type
CR 2025) into the support, positive pole fac-
ing up .

3) Push the support back into the remote con-

trol .

Never put discharged batteries in
the household waste . To protect the
environment, always take them to a
special waste disposal, e . g . collection
container at your retailer .

5 Important Notes:

Speaker Connection

Only use one of the four connection methods
described below; otherwise, the amplifier may
be damaged! In case of overload, the protective
circuit will respond: The LED PROT (8) will light
up and the speakers will be muted .
1 . Connect 100 V speakers to be switched on

and off via the buttons ZONES (7) to the ter-
