Connect the module to the surround cube speakers Use the 50 foot (15 m) cable with gray connectors to join the Acoustimass module to the surround speakers. • The gray connector marked LS goes into the gray terminal on the left surround speaker (to your left as you face the TV). • The gray connector marked RS goes into the gray terminal on the right surround speaker. At the Acoustimass module, make sure the gray connectors are firmly inserted into the LS and RS OUTPUT TO CUBE SPEAKER jacks. Connect the module to the receiver Use the 20 foot (6 m) cable with five wire pairs to connect the Acoustimass module to your surround sound receiver. 1. Connect all wires to the receiver in phase (+ to + and – to –). a. Connect each wire marked with a red collar (+) to the appropriate red (+) output. b. Connect each plain wire (–) to the appropriate black (–) output. 2. Match the label on the red collar of each wire pair to the SPEAKER OUTPUT label on the receiver: a. LEFT wires go to the LEFT FRONT SPEAKER OUTPUT connections. b. CENTER wires go to the CENTER SPEAKER OUTPUT connections. c. RIGHT wires go to the RIGHT FRONT SPEAKER OUTPUT connections. d. LEFT SURROUND wires go to the LEFT SURROUND (rear) SPEAKER OUTPUT connections. e. RIGHT SURROUND wires go to the RIGHT SURROUND (rear) SPEAKER OUTPUT connections. 3. At the Acoustimass module, check to make sure all connectors are firmly inserted into the proper INPUT FROM RECEIVER OR AMPLIFIER jacks. Black connectors go into L and R jacks. Gray connectors go into C, LS, and RS jacks. CAUTION: Do not connect the Acousti- mass module directly to your television unless the television provides surround decoding circuitry and amplified outputs for all channels.

AM189815_04_V.pdf December 20, 2001 1 3 Figure 13 The module end cover fits over the cables Setting Up Attach the module end cover, if needed The module end cover is designed to hide the cabling and extend the smooth, clean lines of the Acoustimass® module. However, because the cover has a beveled surface, you cannot stand the module on that end with the cover in place. If you plan to use the cover, attach it to the cable end after all connections have been checked (Figure 13). Gently push the end cover into the grommets on the Acoustimass module. Your set up is complete. Enjoy your Acoustimass-6 speaker system.

During a surround sound program, the front and center speakers will emit sound almost constantly, while the surround speakers may be silent for periods of time. How to set your Pro-Logic receiver For use in video applications, be sure the SURROUND SOUND center mode setting of your receiver is on NORMAL (Figure 14). You may press in the button labeled Loudness (Bass Boost or Super Bass on some receivers) to see if you prefer that video sound. Use the test tone on your receiver to further verify connections and to adjust the volume level of the speakers. To use the test tone 1. Press test tone ON at the remote. 2. Listen and confirm that each speaker reproduces sound as the tone moves from speaker to speaker in this order: LEFT, CENTER, RIGHT, SURROUND. One tone should come from both SURROUND speakers at the same time. 3. Adjust the volume levels of the CENTER and SURROUND speakers to achieve the balance you prefer for your listening area. Instructions for this process vary, depending on the brand and model of receiver you are using. Follow your receiver owner’s guide instructions for more details on using the test tone. To balance the bass and treble Upholstered furniture, wall-to-wall carpets, or heavy drapes can muffle treble (high notes), making your speaker system sound bass heavy. Bare floors and walls and hard surface furniture can make your speaker system sound too shrill. After listening to your speakers, you may want to adjust the balance of bass and treble. You can use the bass and treble controls on your receiver. Suggestion for spacious stereo sound Try setting your receiver to the PHANTOM surround mode while listening to music from a CD or cassette tape. This will enable you to enjoy a wide stereo image reproduced by the front speakers, plus the ambience and spaciousness provided by your surround speakers. If your receiver has a Loudness button, turn that off during regular stereo playback. How to set your Dolby Digital (AC-3) receiver Your Acoustimass-6 speakers are compatible with the output from Dolby Digital (AC-3) receivers. Take special care to set the channel output according to the specifications listed in the chart below. The Acoustimass speaker system is a full-range system and must be set as LARGE speakers on the Dolby Digital screen menu. An exception is the center speaker, which must be set as SMALL. Turn the subwoofer OFF. Finally, turn the LFE (low-frequency effects) ON and set the crossover frequency to 200 Hz.

If you still have a problem, contact your Bose® dealer to arrange for service. Or, to contact Bose directly, refer to the inside back cover of this guide. • Make sure the power cord of the receiver is plugged into an operating AC wall outlet and the receiver is turned on. • Be sure to select a source at the receiver (video, CD, tuner). System does not function at all • Check the cube speaker and Acoustimass module connections. Turn ON receiver. • Check connections of external components to the receiver. • Increase the volume. • Disconnect any headphones. No sound • Move the Acoustimass module closer to a wall or corner to increase bass. Move it farther from a wall or corner to decrease bass. Or adjust the bass/treble control on the receiver slightly. Not enough or too much bass Cleaning the speakers Wipe the cube speakers using a damp cloth. Do not use solvents or chemicals. Do not allow liquids to spill on or objects to drop into the Acoustimass module or the speaker grilles. You may vacuum the grilles carefully; the drivers are directly behind the grille cloth. No other maintenance is needed. No bass Sound is distorted • Make sure speaker cable is not damaged. • Reduce the volume of any external components connected to the receiver. • Make sure the speaker connections at the receiver or amplifier are correct (+ to + and – to –). • If you are using the Dolby Pro-Logic mode, make sure surround sound is turned ON. • If you are using Dolby Digital (AC-3) programming, verify that the settings are correct at the receiver. Also, be sure the source material (laser disc or broadcast programming) is Dolby Digital or AC-3 encoded. • If your surround sound receiver is Pro-Logic, be sure your receiver is connected to a stereo sound source (TV, VCR, laserdisc or DSS player) by an RCA stereo cable. If the receiver is connected directly to a stereo television, make sure that all other program sources (VCR, laserdisc or DSS player) are connected to the TV using RCA stereo cable as well. • If your surround sound receiver is Dolby Digital (AC-3), be sure the sound source (DSS, laser disc or DVD player) is connected directly to your receiver as described in your receiver owner’s guide. No surround sound
