Using your receiver’s test tone to verify connections and adjust

the volume level

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.

Balancing 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.

Listening to spacious stereo sound

Try setting your receiver to the HALL, DANCE, or JAZZ surround mode while listening to

music from a CD or cassette tape. This enables you to enjoy a wide stereo image reproduced

by the front speakers, plus the ambience and spaciousness provided by your surround

speakers.

Listening to 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.

Note:

If your television has surround sound or any sound enhancement feature built in

(“wide” or “enhanced”), turn it off. Set the TV for stereo playback only.

Using your Dolby Pro-Logic receiver

For use in video applications, be sure the SURROUND SOUND center mode of your receiver

is set to NORMAL (Figure 11). You may depress the Loudness button (Bass Boost or Super

Bass on some receivers) to see if you prefer that video sound.
