2 Safety Notes
This unit corresponds to the directive 89/336/EEC for
electromagnetic compatibility.
The unit is suitable for indoor use only. Protect it
against humidity and heat (admissible ambient tem-
perature range 0 – 40 °C).
For cleaning only use a dry, soft cloth, by no means
chemicals or water.
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 other purposes
than originally intended, if it is not correctly connect-
ed, operated, or not repaired in an expert way.
If the unit is to be put out of operation definitively,
take it to a local recycling plant for disposal which is
not harmful to the environment.
3 Applications
The amplifier PA-302 has especially been designed for
12 V or 24 V DC operation. It can be used for an-
nouncements, for PA music applications, and as an
intercom system. To activate a sound, the PA-302 is
equipped with an audio generator for siren and fog
horn.
4 Mounting
For mounting, two brackets (1) are supplied with the
unit. They can be fastened with screws to the sides of
the amplifier (shown in figures 1 and 2). If the internal
speaker is used, leave some space above the ampli-
fier for the output of the sound while mounting. For the
microphone a support (16) is supplied which accom-
modates the microphone when it is not in use.
5 Making the Connections
All connections should only be made by qualified per-
sonnel and in any case with the amplifier switched off!
1) Connect the supplied microphone to the jack
MIC (2).
2) Connect the speakers (min. impedance 4 Ω) for PA
applications to the terminal strips LSP 1 and LSP 2
(13). These speakers are also used as micro-
phones for the reply during intercom operation.
