Using Your Acoustimass

-6 Speakers

For realistic home theater sound

Each speaker produces only the sound directed to it by the steering logic in your surround

sound receiver. 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.

Center ................................................................. SMALL

Left and Right Surround ..................................... LARGE

Follow the receiver owner’s guide instructions for using the receiver test tone to verify your

connections and to adjust the volume levels of the speakers.
