Quadraphonic (4 channel), stereo (2 channel). The following are two common scenarios.

Example I : 7.1ch. Speaker Set for Home Theater

Figure 2.1-1 7.1 Speaker Setup

Assuming you are building your home theater system with 7.1ch speaker set. Once you have

bought the speaker set with Realtek audio codec inside, you may follow the procedures to

correctly enable the speaker configuration.

Step I: Plug in the device in any available jack. Preferably at the default setting; e.g. the

default setting of the front speaker is the green jack of the rear panel.

Step II: A Dialogue Window of The current connected device will pop up for your selection.

You may click OK once you confirm it is an appropriate setting.

Step III: A useful check out icon (with circle above) is designed to help you hear and verify

the sound exactly from the designated speakers.

Additional Appl ications

Speaker Fill

Definition: Speaker Fill creates a virtual environment for playback of stereo audio sources

on surround speaker systems

Example: When you playback a MP3, and you will hear sound appear from every

speaker of a 7.1ch set once you enable the speaker fill

Swap center/subwoofer speakers

Definition: It is an option to make low frequency sound playback from subwoofer. Users

do not need to check this item if low frequency sound is from subwoofer already.

Bass Management

Definition: Bass Management enhances or redirects frequencies below crossover point

to reduce loss or distortion of bass signals. It will facilitate users to obtain the best bass

enjoyment.

Full Range Speaker

Definition: This is a reminder for users to confirm the speaker system is full or small

range, for small range speakers cant output full frequency audio streams.

Optional Speakers

Definition: The default setting is to assume users equip with subwoofer with their 7.1ch

speaker set, thats why you could see with a check sign. However, if users dont have

subwoofer, we need to blank the option and suggested to enable bass management to

make sure low frequency audio streams will be playback.

Movie mode

The movie mode is for use with stereo television shows and all programs encoded in Dolby

Surround. The result is enhanced soundfield directionality that approaches the quality of

discrete 5.1-channel sound

Music mode

The music mode is for use with any stereo music recordings, and provides a wide and deep

sound space. The Music mode includes controls that allow the sound to be tailored to

individual listening tastes.

Panorama control

This extends the front stereo image to include the surround speakers for an exciting

wraparound effect with side-wall imaging. It is particularly effective for recordings which

have left- or right- channel elements in the mix, as these are detected and accentuated

by the Panorama process.

Dimension control

This allows the user to gradually adjust the soundfield either towards the front or the rear.

This can be useful to help achieve the desired balance from all the speakers with certain

recordings that may contain either too much or too little special effect. Step 0 is the

recommended setting, which has no effect on the sound. Step 1, 2 and 3 gradually move



30/47


sound forward, and steps 1, 2, and 3 move the sound toward the surround.

Center Width control

This allows center-channel sound to be positioned between center speaker and left/right

speakers over a range of eight steps. Step 3 uses a combination of all three front

speakers to give the best vocal imaging and most seamless soundstage presentation,

and is recommended for most recordings. Step 0 places all center sound in the center

speaker. Step 7 places all center sound equally in the left/right speakers, just as in

conventional stereo.

All three of the above controls may be used alone or in any combination. It is recommended

that you try them on a few programs. After try, it is easier to find the settings that are

preferable.
