3 Applications
The amplifier PA-704 provides a maximum out-
put power of 70 W and is specially designed for
small PA systems . 100 V speakers, 70 V speakers or
low-impedance speakers can be used (please refer
to the examples on page 3) . For the connection of
audio sources, 4 inputs are available:
2 microphone inputs
1 input for audio units, such as CD / MP3 player,
radio or tape deck
1 input for turntables with magnetic system
4 Setup Options
When setting up the amplifier, make sure that
the cooling fins are not covered and that air will
be able to flow freely to ensure sufficient cooling .
5 Connecting the Amplifier
The inputs and speakers may only be connected
when the unit is switched off!
5.1 Inputs
AUX (13)
Connection for a unit with line
output, e . g . CD / MP3 player,
tape deck or turntable with
ceramic system
PHONO (14)
Connection for a turntable with
magnetic system
MIC 1 and 2 (15) Connections for low-imped-
ance microphones
5.2 Speakers
Numerous connections, e . g . those for the speak-
ers, are underneath the protective cover (11) . For
connection, unscrew the cover .
WARNING
Do not operate the amplifier with-
out the protective cover (11) . During
operation, there is a hazard of con-
tact with a dangerous voltage of up
to 100 V at the speaker terminals (10) . After con-
necting, screw on the cover again so that the
terminals are protected against any accidental
contact .
The speakers can be connected as shown in figs . 3
and 4 . Connect them to the screw terminals (10)
accordingly . When connecting, observe the cor-
rect individual or total impedance of the speakers
and their correct polarity (positive and negative
connections as shown in figs . 3 and 4) . The pos-
itive connection of the speaker cable is always
specially marked .
Attention!
When PA speakers with 70 V or
100 V audio transformers (fig . 3) are used, the
total load of all speakers must not exceed 35 W
RMS; otherwise, the amplifier will be overloaded
and may be damaged .
