The heat being generated in the unit has to be
removed via air circulation. Therefore, the air vents
at the housing must not be covered.
G
Do not set the unit into operation, and immediately
disconnect the mains plug from the mains socket if
1. there is visible damage to the unit or to the mains
cable,
2. a defect might have occurred after a drop or simi-
lar accident,
3. there are malfunctions.
The unit must in any case be repaired by skilled per-
sonnel.
G
A damaged mains cable must only be replaced by
skilled personnel.
G
Never pull the mains cable to disconnect the mains
plug from the mains socket, always seize the plug.
G
For cleaning only use a dry, soft cloth, never use
chemicals or water.
G
No guarantee claims for the unit and no liability for
any resulting personal damage or material damage
will be accepted if the unit is used for purposes other

Important for U. K. Customers!
The wires in this mains lead are coloured in
accordance with the following code:
green/yellow = earth
blue = neutral
brown = live
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured
markings identifying the terminals in your plug, pro-
ceed as follows:
1. The wire which is coloured green and yellow must
be connected to the terminal in the plug which is
marked with the letter E or by the earth symbol ,
or coloured green or green and yellow.
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.

Applications
This PA amplifier is suitable for small PA systems.
Either PA speakers (100 V/ 70 V/ 25 V) or low imped-
ance speakers (minimum impedance 4 Ω) may be
used at its output. It is equipped with:
2 × microphone input, channel MIC 1 with a priority cir-
cuit for automatic attenuation of the volume of the
other channels
1 × line level input for connection of an audio unit
1 × CD player
1 × button for chime and alarm siren
The amplifier can be operated with 230 V~ or 12 V .

Setting-up and Connecting the Unit
Place the amplifier so that no heat accumulation can
occur and the vents will not be covered.
Prior to connecting or changing connections switch
off the PA-802CD and the units to be connected.
The terminals for the speakers and the 12 V supply
are below the protection cover (17). For connecting,
remove the cover.
1) Microphones may be connected to both inputs
MIC 1 (3) and MIC 2 (4).
The input MIC 1 is equipped with a priority circuit
(talkover). If talking into the microphone is made at
sufficient volume, the volume of all other input
channels will be attenuated so that the announce-
ment can be heard better.
2) An audio unit with line level output (mixer, MP3
player, tuner, etc.) may be connected to the mono
jack LINE (5). When connecting a stereo unit, a
stereo-to-mono adapter must be used, otherwise
the right channel will not be reproduced (e. g. SMC-1
from MONACOR).
3) To the terminals of the speaker output (19)
either
connect 100 V, 70 V or 25 V speakers (figs. 4a, 4b
and 4c) – the amplifier output can be loaded with
18 W as a maximum by the speakers, otherwise it
may be damaged
or
connect a speaker or a speaker group with a total
impedance of 4 Ω as a minimum to the terminals
“4 Ω” and “COM”. Figures 4d to 4g show different
ways to obtain the correct impedance. However,
there are still further possibilities.
When connecting the speakers, always observe the
correct polarity, as shown in the figures.
4) For operation with 12 V connect the 12 V voltage
source to the terminals 12 V (18).
However, as an alternative it is also possible to
connect a 12 V emergency power supply to the ter-
minals. In case of a mains failure the amplifier con-
tinues to operate.
5) For mains operation connect the plug of the mains
cable (23) to a socket (230 V~ / 50 Hz).
WARNING
Never operate the amplifier without the
cover (17). Otherwise there is an elec-
tric shock hazard when touching the
connections.
If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.
