Observing Correct Speaker Wire Polarity
When you connect speakers to your amplifier, you will notice that one side of the two
conductor speaker wire will have some sort of mark: either printing, a raised ridge on the
insulation, or a different color of conductor to let you know which wire to connect to the
positive and which to the negative speaker terminals so you can repeat the connection on the
power amplifier's binding posts.
Configuring the PAL-80, PAL-65, and PAL-45 for Stereo or Monaural Operation
Refer to the Drawing on Page 5
Parasound in-ceiling loudspeakers are two speakers in one: with dual tweeters, dual woofer
voice coils, dual crossovers, and separate 8 Ω terminals for both inputs. When using the
speaker input assignment switch, you can configure the PAL-80, PAL-65, PAL-45 for three
different installation requirements.
Paralleled Stereo Operation, 4 Ω
This is the most typical configuration where each speaker is used to reproduce the left or
right channel signal from the amplifier. This usually means that at least two speakers will be
used in the room or zone.
1. Connect the output of the appropriate channel of the power amplifier to the speaker
terminals on the left side of the crossover PCB.
2. Set the input assignment switch to its “Paralleled Input” position.
3. Repeat steps 1 and 2 for the other speaker which will reproduce another channel.
IMPORTANT NOTE: If you connect the amplifier to the speaker terminals on the right side
of the crossover PCB while its switch is in the “Independent Inputs” position, there will be
no output.
Monaural Operation, 8 Ω
In this configuration, the left and right amplifier signals are reproduced by the dual speaker
elements so you can hear both channels from one speaker. This is useful for a small area
such as a bathroom or short hallway where there is no advantage to using two speakers. You
can also use this configuration in a large room with multiple speakers where uniform coverage
is a higher priority than creating a stereo image.
1. Connect the left channel output of the power amplifier to the speaker terminals on the
left side of the crossover PCB.
2. Connect the right channel output of the power amplifier to the speaker terminals on the
right side of the crossover PCB.
3. Set the Input assignment switch to the “Independent Inputs” position.
Independent Stereo Operation, 8 Ω
In this configuration, one amplifier channel drives only one woofer voice coil and tweeter.
Use this configuration only if you want to reduce the load on the amplifier or if you want to
control the high frequency dispersion by selecting the channel corresponding to the direction
of only one of the tweeters.
1. Connect the left output of the power amplifier to either pair of speaker terminals.
2. Set the Input assignment switch to the “Independent Input” position.

Three Position Treble Adjustment
The High adjustment slide switch on the front of the speaker allows you to adjust the
tweeter level - 3 dB or +3 dB from its 0 dB middle position. If you are mounting the
speaker in a “live” room with many reflective surfaces, you may want to attenuate its
treble response. Conversely, if you are mounting the speaker in a “dead” room with many
absorbent surfaces, you may want to boost its treble response.
Installing Precision Architectural Loudspeakers
1. Confirm that there is at least 1 1/2" of clearance between each edge of the planned
cutout and adjacent studs or joints.
2. Fasten the supplied cardboard template to the wall or ceiling with tape or thumbtacks.
Check again for equal distance of both speakers from the wall.
3. Trace around the perimeter of the template.
4. Before making the final cutout, make a small “test cutout” in the center of the penciled
outline. Reach inside the test hole to verify that there are no obstructions in the way of
your planned cutout.
5. Before cutting the hole, first score the drywall with a razor knife and use a keyhole
saw to complete the cut. Remove debris from the edge of the hole.
7. Secure the speaker wire to a stud near the cutout so its weight will not tug on the
terminals of the speaker after it is connected. This also keeps the wire from dropping
behind the wall before you can connect it.
8. Push down the tab on the speaker terminals and insert the speaker wire into the
connector.
9. Insert the speaker into the cutout to make sure it fits easily without forcing.
10. Evenly tighten the mounting screws on the bezel. The mounting “swing-arms” will
automatically swing out 90 degrees.After they swing out, the arms then clamp against
the drywall from behind the wall. Avoid using excessive force to prevent deforming
the drywall or cracking the speaker’s mounting frame.
11. We recommend that you add a “blanket” of sound absorbing material such as ceiling
insulation behind the woofer to reduce sound transmission into the adjoining room.
Additionally, any sound leakage from behind the molded frame can be blocked with
foam weather-stripping directly behind the plastic speaker bezel.
