2 Introduction Congratulations on your purchase of your PAL-380 Precision Architectural Loudspeaker system and thank you for choosing Parasound. The PAL-380s were developed using the finest loudspeaker and crossover components available. Countless hours of computer modeling were spent to insure accurate audio reproduction in a variety of installations where placement compromises must sometimes be made. The PAL-380 Precision Architectural Loudspeakers deliver the high-fidelity audio reproduction you have come to expect from high-end loudspeakers in a cabinet. Please take a few minutes to read these instructions thoroughly to make the installation easier and insure optimum performance. Unpacking and Inspection Carefully unpack your PAL-380 loudspeakers locate the enclosed accessories: Qty Description 2 PAL-380 baffle and loudspeaker assembly 2 Removeable bezels with mounting dogs 2 Metal grilles 6 #8 x òÓ screws 6 Rubber shoulder washers 2 Foam grille inserts Be sure to carefully inspect the speakers 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-wall 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. The PAL-380 Precision Architectural Loudspeakers mount into standard 4 inch (or greater) stud depth walls. 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 conflicting material that might be damaged before beginning the installation. Prewiring Before you purchase loudspeaker wire, check local building codes to make sure that the wire is rated to comply with applicable local safety codes such as UL or CL-2. Use only stranded wire no thinner than AWG 16. For runs longer than 100 feet, we recommend minimum of AWG 14. When pulling wire, take care not to pull the wire too fast to prevent 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. When securing the wire inside the walls, be careful not to pierce the insulation with nails or staples.

3 For best performance and easier troubleshooting, always Òhome runÓ wiring when installing multiple speakers rather than connecting from one speaker to the next. When connecting multiple speakers, make sure that the power amplifier is capable of adequately driving the combined impedance of the speakers. If not, you may need additional amplifiers or an impedance protection device that are often built into loudspeaker selection boxes. Mirror Image Midrange and Tweeter Assembly The PAL-380 midrange and tweeter assembly are mirror imaged so you can position them for best sonic imaging. Ideally, the listening position should be at one point of an equilateral triangle with the left and right speakers positioned at the other two points. If you need to mount the speakers outside this idealized equilateral triangle, position the tweeters toward the middle. If you need to mount the speakers inside this idealized equilateral triangle, position the midrange drivers toward the middle. Installing the PAL-380 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 ceiling or floor. 3. Use a level or the included templateÕs self-leveling feature so the cutout will be level. 4. Trace around the perimeter of the template. 5. Before making the final cutout, make a small 6-inch square Òtest cutoutÓ 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. 6. 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. Terminate the speaker wire with 1/4" spade lugs or banana plugs. You can also insert bare wire up to AWG 12 into the holes on the sides of the binding posts. 9. Carefully separate the removable bezel from the baffle and loudspeaker assembly. The bezel can be mounted in the wall and painted if desired while the main part of the loudspeaker is stored away safely until you are ready to mount it. Note: The grilles should be painted separately rather than while mounted in the separate bezel. 10. Insert the PAL-380 bezel into the cutout to make sure it fits easily without forcing. 11. Evenly tighten the mounting screws on the bezel. The mounting Òswing-armsÓ (also known as mounting ÒdogsÓ) 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 speakerÕs mounting frame. 12. We recommend that you add a ÒblanketÓ 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. 13. Install the main loudspeaker assembly into the bezel. 14. Install the six rubber shoulder washers into the holes in the bezel 15. Use the six supplied #8 x òÓ screws to fasten the loudspeaker assembly into the bezel.
