Introduction
Congratulations on your purchase of this Precision Architectural Loudspeaker system and
thank you for choosing Parasound. The P AL-80, PAL-65, and P AL-45 Precision Architectural
Loudspeakers were developed using the finest driver and crossover components available.
Countless hours of computer modeling were spent to insure accurate audio reproduction in
a variety of installations where placement compromises are sometimes unavoidable. The
PAL-80, PAL-65, and PAL-45 are virtually identical in operation and installation, except
that the larger woofers provide more extended low frequency response and higher power
handling capability . Please take a few minutes to read these instructions thoroughly to make
the installation easier and insure the best performance of your new Precision Architectural
Loudspeakers.
Unpacking and Inspection
Unpack your loudspeaker and the enclosed accessories:
Quantity Description
1 Baffle and loudspeaker assembly
1 Metal grille
1 Foam grille insert
1 Paint Shield
1 Cutout Template
Be sure to inspect the speaker for any signs of shipping damage. If you notice any, contact
your Parasound Dealer immediately.
Precautions
If you have any doubts about your ability to properly install in-ceiling loudspeakers, you
should consider the services of a custom installer. If you plan to install them yourself, always
use good quality tools to save time and make the installation go more smoothly . You should
determine the final location of both left and right speakers before cutting any holes since
changes to one speaker may affect the other either aesthetically or acoustically. Look for
pipes, wiring or any other material that might interfere with the installation.
Prewiring
Before you purchase loudspeaker wire, check local building codes to make sure that the
wire is rated to comply with applicable safety codes such as UL or CL-2. Use only stranded
wire no thinner than AWG 16 (lower AWG numbers equate to thicker wire). For runs longer
than 100 feet, we recommend minimum of AWG 14. When pulling wire, take care not to
pull the wire too fast. This prevents stretching the wire or scorching the insulation from
friction. Leave 2 to 3 feet of excess loudspeaker wire at both ends; it is easier to trim off
excess wire than to splice additional wire later . When securing the wire inside the walls, be
careful not to pierce the insulation with nails or staples.
For best performance and easier troubleshooting, always “home run” wiring when installing
multiple speakers rather than connecting one speaker to the next. When connecting multiple
speakers, make sure the power amplifier is capable of adequately driving the combined
impedance of the loudspeakers. If it cannot, you may need additional amplifiers or an
impedance protection device.

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.
