SPEAKER POSITIONING

The installation positions of speakers differ according to the size, and acoustics of the listening room. While actually listening to a program source, try various speaker positions to determine which layout provides the best surround effect.

•Front speakers Place to the front left and right of the listening position. Front speakers are required for all surround modes.

•Center speaker Place front and center. This speaker stabilizes the sound image and helps recreate sound motion. Be sure to connect a center speaker when using the 3 STEREO mode.

•Rear speakers Place to the direct left and right. These speakers recreate sound motion and atmosphere. Required for surround playback. For best results, do not install the rear speakers too far behind the listening position and install them above the level of the listener’s ears. It is also effective to direct the rear speakers towards a wall or ceiling to further disperse the sound.

•Subwoofer Reproduces powerful deep bass sounds.

SPEAKER CONFIGURATION

• Refer to OSD speaker configuration. (page 17)

It is important to perform speaker configuration prior to using the decoder. This allows the unit to sense the available speakers and automatically select decoding modes. It is possible to receive multi-channel surround sound without a center speaker, but for best results with Dolby Pro Logic and Dolby Digital decoding, at least 5 speakers (Left, Center, Right, Left Rear and Right Rear) should be used.

CENTER SPEAKER MODE

•LARGE: Use this mode with a large center speaker. The center channel’s output is full range.

•SMALL: Use this mode with a small center speaker. Bass frequencies below 90 Hz are output from the speaker selected by LFE/Bass Out.

•NONE: Use this mode if there is no center speaker. The center channel signal will be divided between the main L and R speakers.

REAR (SURROUND) SPEAKER MODE

•LARGE: The mode to choose if a large speaker is used or if a subwoofer is connected in parallel. The rear channels full range is output as is.

•SMALL: The mode to choose if small speakers are used. Frequencies of 90Hz and below are output to the speaker selected by LFE/Bass Out.

FRONT SPEAKER MODE
