Power Supply - Monacor PA-400 Manual De Instrucciones

A Y cable is required for stereo units with two outputs
so that both outputs are led to the corresponding com-
mon amplifier input.
If the turntable has a separate ground cable, connect it
to the GND screw (12).
5.2 Speakers
The speakers can be connected as shown in fig. 3-8.
Connect them to the terminals (10) accordingly. Pay
attention to the correct individual resp. total speaker
impedance as well as to the correct phase connection
of the speakers (positive and negative connections, as
shown in fig. 3-8). The positive connection of the
speaker cable is always specially marked.
The total load of all speakers must not exceed
20 W when using PA speakers with 100 V audio
RMS
transformer (fig. 8), as otherwise the amplifier will be
overloaded. This may result in amplifier damage.

5.3 Power Supply

Finally, connect the amplifier to a power supply:
1. either via the power cable (8) to a mains supply
(230 V~/50 Hz)
2. or via the DC voltage jack (9) with 12 V . In this
case, the mains plug must not be connected to the
mains socket. When installing in a motor vehicle
pay attention that the vehicle chassis is connected
to the negative pole of the car battery. Otherwise
connect the connection cable to the adapter of the
cigarette lighter. The adapter is equipped with a
fuse which also melts when the poles are connect-
ed wrongly. If necessary, replace the fuse with ano-
ther of the same electric values (fig. 9).
6 Operation
1) Turn the MASTER VOLUME control (5) to zero
before switching on. Switch on the amplifier via the
POWER switch (6).
2) Set the Phono/AUX selector (11) to the AUX posi-
tion. The selector must be set to PHONO position
only if a turntable with magnet system is used.
3) Slightly turn up the MASTER VOLUME control (5).
Adjust the desired volume in relation to each other
via MIC 1, MIC 2 (2), and PHONO/AUX (3). Set all
controls which are not connected to a source to
zero.
4) Adjust the tone with the TONE control (4) and the
total volume with the MASTER VOLUME control (5).
5) If desired fade the microphones in and out with the
MIC 1 and MIC 2 (2) controls resp. the music
source with the PHONO/AUX control (3).
