2 Introduction Congratulations on your purchase of this Precision Architectural Loudspeaker system and thank you for choosing Parasound. The PAL-80, PAL-65, and PAL-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 Òhome runÓ 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.

3 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 W 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 W 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 ÒParalleled InputÓ 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 ÒIndependent InputsÓ position, there will be no output. Monaural Operation, 8 W 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 ÒIndependent InputsÓ position. Independent Stereo Operation, 8 W 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 ÒIndependent InputÓ position.
