AMPLIFIER 8 W/2 Ohm - P6241
To be installed on 8" loudspeakers
DESCRIPTION
Amplifier for 8" loudspeakers, which can supply 8W over a load of 2 Ohm. It comes in
the same plastic support as the ceiling units, but without a loudspeaker, so that several
different loudspeaker and power combinations can be created.
The amplifier’s sound level can be controlled by the sensitivity adjustment potentiome-
ter.
As an example, the enclosed table shows some possible combinations and the watts per
sound point that would be obtained.
The amplifier is attached to one of the loudspeakers in order to form a ceiling
speaker-like assembly which can be fitted onto the ceiling. First, the Red and Black
wires are connected to the loudspeaker’s + and - terminals; next, the amplifier is
firmly attached to the loudspeaker magnet with the supplied special adhesive that
is on its inner part. The remaining loudspeakers are to be connected in parallel to
terminals A and M which are on the connecting strip. The connection of this assembly
is identical to that of a simple ceiling loudspeaker.
a) Installation 1 stereo music channel.
(J1 bridge uncut). Connection to control unit via
three cables (Terminals 3,4 and 05/06).
With this type of connection, all of the amplifier’s power
is obtained through terminal 3 of the control unit, and
it is recommended that a maximum of 2 amplifiers are
connected to the control.
One control can only supply enough power for 2 ampli-
fiers, (estimating that with music + announcements,
the amplifier’s power consumption is only 65% of its
maximum).
The diagram shows an installation of 1 stereo channel
with two amplifiers, one for the right channel and one for
the left, to which two P4711 (8"/4 Ohm) loudspeakers
have been connected, thus obtaining 4W per sound
point, 16 W in total.
Note: The control unit could be any one of the Prestige
series. Do not forget to set the mono/stereo control
switch to the stereo position.
ASSEMBLY
CONNECTION
(*)Note:
This amplifier comes with terminals 2 and 3 internally connected via the J1 bridge, which may be optionally cut and allows the possibility of two
methods of connection.
With J1 uncut (see example “a”):
the power supply may be connected to either one of the terminals 2 or 3.
With J1 cut (see example “b”):
terminal 2 acts as power supply input and 3 as the power on-off control.
1 - Adhesive label to secure assembly to
loudspeaker
2 - Wires for connection to loudspeaker
terminals
3 - Connector strips

5 - “J1” bridge. See Note (*) in
“CONNECTION” section
TERMINALS
-terminal 2 – Power 16V
-terminal 3 - Input power 16V. See Note (*)
-terminal 4 - Ground
-terminals 05/06 - Audio input
-terminals A and M - Output for set of loudspeakers to be connected
in parallel.
-Red and black wires - Audio output to be connected to the + and - ter-
minals of the 8"loudspeaker, on top of which the amplifier is placed
.
