SPEAKER PLACEMENT Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. These recommendations are for the optimum placement of the loudspeakers. Use these placement recommendations as a guide. Slight variations will not diminish your listening MODEL: L810 As front speakers As surround speakers pleasure. All of the Studio™ L Series loudspeakers referred to in this guide are videoshielded and may safely be placed near a television. 5–6 ft. (1.5m–1.8m) MODEL: L820 The L820 loudspeakers are designed to be oriented horizontally, as shown in the illus- trations below. Although these loudspeakers are designed as a mirrored pair, the decision as to which one is left or right will depend on the amount of space left between them. A wider stereo image is presented with the tweeter/ midrange array outboard, and a tighter image is presented with the array inboard. For stereo-only applications: Less than 6–8 feet (1.8m–2.4m) More than 6–8 feet (1.8m–2.4m) For home theater applications: 0–2 ft. (0–0.6m) This placement provides a wide spread in sound, supplemented by the center channel speaker. MODEL: LC2 The LC2 center channel loudspeaker is designed to complement all of the Studio L Series loudspeakers. This speaker is ideal for re-creating the cinematic experience in your home. 5–6 ft. (1.5m–1.8m) ® ™ STUDIO L SERIES L810, L820, LC2 OWNER’S GUIDE SPEAKER CONNECTIONS MODELS: L810, L820 RIGHT – LEFT + – – + RIGHT – + + LEFT Receiver’s Speaker Speaker Outputs Receiver’s Outputs MODEL: LC2 – + – + Receiver’s Speaker Outputs Speakers and electronics have corresponding (+) and (–) terminals. It is important to connect both speakers identically: (+) on the speaker to (+) on the amplifier and (–) on the speaker to (–) on the amplifier. Wiring “out of phase” results in thin sound, weak bass and poor imaging. To use the binding-post speaker terminals, unscrew the colored collar until the pass-through hole in the center post is visible. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. The hole in the center of each collar is intended for use with banana-type connectors. To comply with European CE certification, these holes are blocked with plastic inserts at the point of manufacture. To use banana-type connectors requires the removal of the inserts. Do not remove these inserts if you are using the product in an area covered by the European CE certification. SPEAKER SETUP MODELS: L810, L820, LC2 The supplied self-adhesive rubber feet may be attached to the bottom corners of your speakers to protect your furniture. Place pads here BI-WIRING The bi-wire connection method requires one amplifier and two sets of speaker wires. By removing the shorting bars, connections may be made to the individual network sections using four conductors, one for each of the four terminals. For single-wire connection, leave the shorting bars in place and connect only a single set of speaker wires (two conductors) to the two upper terminals.

Distance Between Pilot Holes L810 6" (152mm) L820 8-1/2" (216mm) LC2 14-1/2" (368mm) • This product is not intended for ceiling mounting. Two Number 8 roundhead or panhead screws should be used for each loudspeaker. The screwhead should be between 5/16" (8mm) and 1/4" (6.3mm) in diameter, and the screw should be at least 2" (50mm) in length. When installing screws in any wall, it is always preferable to screw them into a wall stud. If none is available, it is important to always use properly selected wall anchors. Attach two of the four selfadhesive rubber pads that came with the loudspeaker to the back of the enclosure in the two bottom corners so that the cabinet is spaced evenly from the wall. Select a suitable mounting location on a wall. (The ceiling is not a suitable mounting location.) Drill two pilot holes, appropriately sized for the specific self-tapping screw or wall anchor that you will be using. A template is included with your loudspeaker that indicates the proper locations for the pilot holes. In the event that the template is missing, refer to this chart: See Figure 1. The holes should be 2-1/4" (57mm) below where you want the top of the enclosure to be positioned. Use a carpenter’s level to ensure that the holes are even and that the speaker will mount on the level. Install the two screws into either a wooden wall stud or anchor, and tighten them until the back of each screwhead is about 1/8" (3mm) from the wall. See Figure 2. Models L810 and L820 may also be corner-mounted using the keyholes located on the bezeled corners. For corner mounting, fold the mounting template in half, place the fold in the corner at the desired height, and use the outer holes. If the template is missing, for corner mounting drill each pilot hole 7-3/4" (197mm) from the corner for model L810, or 9-11/16" (246mm) from the corner for model L820. However, if your corner is not precisely 90 degrees, these measurements may not work. In that case, it is recommended that you contact a professional custom installer, who can determine the correct loca- tions for the pilot holes. Install the loudspeaker by slowly moving the cabinet toward the screws so that the screwheads clear the larger circular portion of the two keyholes. Once both screwheads have entered the keyholes, the loudspeaker should gently be lowered onto the screw shafts. Check that the loudspeaker is firmly locked onto the screws by gently pulling the speaker down and forward.

TROUBLESHOOTING If there is no sound from any of the speakers: • Check that receiver/amplifier is on and that a source is playing. • Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: • Check the “Balance” control on your receiver/ amplifier. • Check all wires and connections between receiver/ amplifier and speakers. • Make sure no wires are touching other wires or terminals and creating a short circuit. • Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. • In Dolby® Digital or DTS® modes, make sure that the receiver/processor is configured so that the speaker in question is enabled. • Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem has followed the speakers, or has remained in the same channel. If the problem is in the same chan- nel, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner’s manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www.jbl.com for further information. If the system plays at low volumes but shuts off as volume is increased: • Check all wires and connections between receiver/ amplifier and speakers. • Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. • If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is no (or low) bass output: • Make sure the polarities (+ and –) of the left and right “Speaker Inputs” are connected properly. • Consider adding a powered subwoofer to your system for use with digital “.1” surround formats. If there is no sound from the surround speakers: • Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, punctured or touching each other. • Review proper operation of your receiver/amplifier and its surround sound features. • Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/amplifier has other surround modes you may use. • In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the surround speakers are enabled. • Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD player’s menu and the DVD’s menu.
