4. Installation

WARNING: Make sure that the speaker is
installed in a stable and secure way in
order to avoid any conditions that may be
dangerous for persons or structures.
Check to make sure that the support surface (e.g.
wall, etc.) has the necessary mechanical characteri-
stics to support the weight of the speaker without the
danger of it falling.
Before suspending the speaker, carefully check all
the components to be used to make sure that there is
no damage, deformation, corrosion and/or missing or
damaged parts that could reduce the safety of the
installation.
In outdoor use, avoid installing the speaker in pla-
ces exposed to harsh weather conditions.
The PL 60 is designed for flush-mount installation
in false ceilings. Before installing the speaker, make
sure that there is sufficient space behind the false
ceiling panel to hold the speaker: with respect to the
support surface of the front flange of the speaker, a
free space of 65 mm (2.56") depth is necessary.
1. Drill a hole of diameter 182 mm (7.16") in the
false ceiling at the point chosen for installing the
speaker.
2. Insert the speaker in the hole as shown in point 1
of Figure 1 on page 22.
3. Screw in the three screws that tighten the three
attachment terminals A of the speaker, as shown
in point 2 of Figure 1 on page 22.
4. Fit the metal protective mesh onto the front of the
speaker as shown in point 3 of Figure 1 on page
22.
The A1360 adapter accessory can be requested for
surface mount installation. To view the complete
updated range of accessories available, contact your
nearest sales point.

5. Connections

WARNING: To prevent the risk of electric
shock, do not connect the speaker with
the amplifier switched on.
Before using the speaker, carefully check that all
the connections have been made correctly to make
sure there are no accidental short circuits that could
cause electrical sparks.
The PL 60 speaker can be connected to constant
voltage audio lines at 70 V or 100 V. Connections are
made using the 5-pin input terminal strip on the rear
part of the speaker.
1. Using the legend in Figure 2 on page 23, locate
the input conductors to be used.
2. Connect the BLACK conductor of the speaker to
the negative conductor (-) of the audio line that
leads from the amplifier terminal marked -, 0, or
COM (Fig. 2).
3. Connect the other speaker conductor located
using the legend to the positive conductor (+) of
the audio line (Fig. 2).
VERY IMPORTANT: To prevent speaker
damage, never use the GREEN conductor
when the speaker is supplied with 100 V
lines.
4. To prevent the risk of electric shock, situate the
terminal strip in an inaccessible position (e.g.
inside the speaker when it is used with the acces-
sory for surface mount installation).
When making the connections, keep the following
indications in mind (Fig. 3, page 23).
• The input voltage selected on the speaker must
correspond with the voltage selected on the ampli-
fier.
• The sum of the operating power values of all the
speakers connected to the audio line must not exceed
that of the amplifier.
• To ensure correct audio reproduction, the con-
nections should be made "in phase", where the +/-
polarities of the amplifier output correspond with the
+/- polarities of the speaker input.
A CLOSER LOOK: When two speakers
reproduce the same frequencies but with
phase differences, these frequencies may
be annulled. In sound systems, speakers are often
situated in adjacent positions and the sound waves
produced interact with each other. If a speaker is con-
nected incorrectly; i.e. the polarity of the audio line
conductors is inverted, the audio signals are tran-
smitted with differences in phase and correct repro-
duction is therefore jeopardized.

6. Service

If the product seems to be not operating correctly,
before contacting the service centre, carry out all the
tests the may confirm the malfunction. In many pro-
ducts taken to the service centre, it is not possible to
reproduce the malfunction indicated because the pro-
blem is probably to be found elsewhere in the sound
system. If the product does require service, place it in
its original packaging and take it to your local dealer
or to the nearest service centre.
