2. The wire which is coloured blue must be con-
nected to the terminal which is marked with the
letter N or coloured black.
3. The wire which is coloured brown must be con-
nected to the terminal which is marked with the
letter L or coloured red.
Warning – This appliance must be earthed.
3 Possibilities of Application and
Installation
The PA amplifier PA-120T is especially designed for
use in small PA systems. Two microphones and a unit
with line output (e. g. CD player, tuner, mixer, etc.) can
be connected. The installed cassette player can e. g.
be used for PA applications with background music.
The PA-120T can be placed as a table top unit or be
screwed with the mounting bracket (10) below a con-
sole.

4 Connecting the Amplifier

All connections should only be made by qualified per-
sonnel and in any case with the amplifier switched off.
4.1 Speakers
PA speakers which operate with 100 V or 70 V tech-
nique (figs. 3a and 3b) or low impedance speakers
(figs. 4a – 6b) can be connected. For the connection
screw off the protection cover (21).
4.1.1 PA speakers
Caution! In case of PA speakers (figs. 3a and 3b)
the total load by the speakers must not
exceed 15 W
will be overloaded and possibly damaged.
Connect the speakers to the corresponding speaker
terminals (20) for the positive pole and COM (18) for
the negative pole. The positive connection of the
speaker cables is always especially coded.
4.1.2 Low impedance speakers
Figs. 4a to 6b show the different possibilities to con-
nect one or two speakers with corresponding im-
pedance. Connect the speaker/s to the terminal COM
(18) for the negative pole and to a terminal correspon-
ding to the impedance (19) for the positive pole. The
positive connection of the speaker cables is always
especially coded.
4.2 Microphones
Connect one microphone each to jack MIC 1 (6)
and/or to jack MIC 2 (8).

4.3 Audio unit with line output
If the built-in cassette recorder is not used, it is possi-
ble to operate a unit with line output (e. g. CD player,
tuner, mixer, etc.) via the input AUX (15).
4.4 Power supply and emergency power
supply
For a permanent operation with power failure back-up
connect a 12 V rechargeable battery to the terminals
"+" and "-" (17). These terminals can also be con-
nected if only a 12 V source (rechargeable battery, elec-
tric system of a car) is available for the power supply.
Finally connect the mains plug of the cable (12) to a
mains socket (230 V~/50 Hz).
5 Operation
Attention! Prior to switching-on, tightly screw on the
protection cover (21) in any case. Without
it the amplifier must not be operated!
When touching the connections (20) there
is a danger of an electric shock.
1) Prior to switching-on, set all three controls AUX/
TAPE (4), MIC 1 (5), and MIC 2 (7) to the left stop
to zero. Thus, switching-on noise will be prevented.
2) For the operation with 230 V mains voltage switch
on the amplifier with the POWER switch (9). With
the 12 V emergency power supply connected, addi-
tionally set the 12 V
the unit is only supplied with 12 V, only actuate the
12 V switch. With the unit switched on, the power
LED above the POWER switch lights up.
Note: If an emergency power supply is connected,
the amplifier is always in operation. With the
POWER button it is only possible to switch over
between mains supply and emergency power sup-
ply. For normal operation switch the POWER button
to mains supply (position ON). In case of mains fail-
ure the amplifier automatically switches to emer-
gency power supply.
3) For microphone announcements turn up the control
MIC 1 (5) and/or MIC 2 (7) according to the desired
volume.
4) To adjust the volume of the cassette player or of
one of the units connected to the jacks AUX (15),
turn up the control AUX/TAPE (4).
When operating the installed cassette player,
the connected unit must be switched off. Otherwise
both signals can be heard.
5.1 Playing a music cassette
1) Insert the cassette with the open side to the right
and with the blank tape spool pointing to the rear
into the compartment (3). The button PLAY/FF/
EJECT (2) jumps out. The indicating LED (1) above
the button lights up and the cassette is played.
2) At the end of the cassette the indicating LED (1)
extinguishes and the replay stops. To eject the cas-
sette, press in the button PLAY/EFF/EJECT com-
switch (16) to position ON. If
