MAIN UNIT P4018SE
2 STEREO CHANNELS, WITH A BUILT-IN TUNER PCD3666
DESCRIPTION
Main unit with 2 stereo channels, 1 stereo channel with manual regu-
lation of audio level and LED indicating optimum output level, 1 stero
channel when including an tuner PCD3666.
GENERAL CHARACTERISTICS
Front audio inputs with CINCH connectors (2,3)
Strip for internal audio input connection
Internal Mono/Stereo selector switch (17).
Built-in power supply unit, 25 VA, supplying 16 Vdc with electronic
filter for general supply of the system (terminal 2) (The unit is normally
supplied to operate at 220/230V although, on order, it can be supplied
at 110V).
Electronic protection against short circuits and overloads in the supply.
Protection against overloads in the audio outputs.
LED indicator (7, red) to activate protection in supply output).
Telecontrol. When any of the controls of the system are activated, the
socket outlet (12) connects automatically supplying the mains voltage
to the sound source. When all the system controls are switched off
this socket outlet automatically disconnects, switching off the sound
source, with the subsequent energy saving. It can also be connected
manually. Optionally it can include an internal strip for telecontrolled
mains output connection.
Selector switch (8) for manual ignition of the outside sound source
regardless of the state of the installation controls.
Mains bipolar switch (11) to totally disconnect the system. Main unit
operation indicator led (6).
It includes a protection fuse for mains input and telecontrolled soc-
ket outlet, and protection of the supply output in low voltage for the
system (apart from the electronic protection). The mains fuse is not
accessible from the outside. To replace it, just remove the front of the
main unit (13). It is not necessary to remove the main unit from its
flushmount box.
All the components used in the connection to the electrical mains are
approved, satisfying the strictest safety standards.

The Main unit will be installed in a flushmount box P4902, preferably
close to the place where the sound source is situated.
The connection to the 220/230V mains will be made with at least 1-mm2
section wires and double insulation. For safety reasons it is also neces-
sary to connect the earth tap.
NOTE: It is advisable for the mains cables to be as far away as pos-
sible from the circuits of the main unit.
The connection to the distribution line can be done with cables, Mod.
P9910 or P9940 (in the case of messages and intercom) for the supply
and music channels. The excess wires can be used if necessary for any
of the auxiliary functions.

TERMINALS:
F
- Phase (220/230 V AC)
N
- Neutral (220/230 V AC)
- Earth (protection conductor)
2
- Positive – 16 VDC rated voltage output / 1.5 A maximum
4
- Negative – Supply and signal mass.
15
- Audio output – Left channel – 3 V RMS max.
16
- Audio output – Right channel – 3 V RMS max.
R
- Auxiliary terminal for telecontrol.
CONNECTION TO MAINS:
Through the slot situated in the base plate
(on the right of the mains switch) screw the mains and earth cables to
the strip (15) situated in the printed circuit.
CONNECTION TO THE SOUND LINE:
Connect the cables of the sound
line making sure you do not make a mistake in the order of the strips
and that you tighten them as much as possible. Place the stereo mono
selector switch M/S (17) in the correct position for its installation.
CONNECTION TO THE SOUND EQUIPMENT:
Connect the mains
supply plug to the telecontrolled mains socket outlet (12). Connect the
audio output of the equipment to the CINCH connectors (2,3) of the front
of the main unit. To do this, use a stereo connection cable (not supplied
with the mains) with CINCH connectors on one end and with the connec-
tors used in your music equipment.
NOTE: The terminal R permits the remote operation of the tele-
control. It is used if two or more units are installed together.
Interconnecting their terminals R, if the telecontrol of one of the
units trips the telecontrol of the others trips at the same time. In
addition, this terminal can be used for the remote trip of the tele-
control. If the terminal R is connected to mass (terminal 4) the
telecontrol trips, exactly the same as if we place selector switch 8
in the LOCAL position.
START-UP:
Once the main unit has been installed in its flushmount box, screw the
base plate to the box and fit the trim frame. Then connect the on/off
switch of the system to supply 220/230V to the main unit.
Apply the mains switch (11) and check that the ON led comes on (6).
Led 7 must not come on, or come on GREEN (indicating activated tele-
control).
Check the telecontrol connecting one of the controls of the system or
applying the selector switch (8). When the telecontrol is activated, led 7
must light up GREEN and the mains socket be activated (12).
Adjust the level of the input signal with the adjustment potentiometer (5)
until the level led (4) gently flickers to the rhythm of the music. Check
that when all the system controls are off (selector switch 8 on REMOTE)
the sound source automatically disconnects after about 30 seconds.
IMPORTANT NOTE: Before connecting this unit to the
electrical Mains the ON/OFF switch of that system must
be disconnected in order to make the connection with
due safety guarantees. Under no circumstances must the unit be
manipulated outside its flushmount box if connected to the alter-
nating current mains. Make sure that the Unit has been correctly
connected to earth.
