Speaker placement

Ideal speaker placement varies depending on the size of your room and the wall coverings, etc. The typical example of speaker placement and recommendations are as follows :

■ Front left and right speakers and center speaker

• Place the front speakers with their front surfaces as flush with TV or monitor screen as possible.
• Place the center speaker between the front left and right speakers and no further from the listening position than the front speakers.
• Place each speaker so that sound is aimed at the location of the listener's ears when at the main listening position.

■ Surround left and right speakers

- Place the surround speakers approximately 1 meter (40 inches) above the ear level of a seated listener on the direct left and right of them or slightly behind.

Subwoofer

- The subwoofer reproduces powerful deep bass sounds. Place a subwoofer anywhere in the front as desired.

Notes :

• When using a conventional TV, to avoid interference with the TV picture, use only magnetically shielded front left and right and center speakers.
• To obtain the best surround effects, the speakers except the subwoofer should be full range speakers.

SURROUND SOUND

- This receiver incorporates a sophisticated Digital Signal Processor that allows you to create optimum sound quality and sound atmosphere in your personal Home Theater.

Surround modes

■ Dolby Digital

Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories. Discs bearing the Dolby Digital logo includes the recording of up to 5.1 channels of digital signals, which can reproduce much better sound quality, spatial expansion and dynamic range characteristics than the previous Dolby Surround effect.

■ Dolby Pro Logic II surround

This mode applies conventional 2-channel signals such as digital PCM or analog stereo signals as well as Dolby Surround signals, etc. to surround processing to offer improvements over conventional Dolby Pro Logic circuits. Dolby Pro Logic II surround includes 2 modes as follows:

• Dolby Pro Logic II MOVIE

When enjoying movies, this mode allows you to further enhance the cinematic quality by adding processing that emphasizes the sounds of the action special effects.

• Dolby Pro Logic II MUSIC

When listening to music, this mode allows you to further enhance the sound quality by adding processing that emphasizes the musical effects.

■ Dolby Pro Logic

This mode expands any 2-channel sources(, including Dolby Surround sources) for 4 channel(front left, center, front right and surround) play back. The surround channel is monaural, but is played through two surround speakers.

Dolby, Pro Logic, and the double-D symbol are registered trademarks of Dolby Laboratories.

- The following modes apply conventional 2-channel signals such as digital PCM or analog stereo signals to high performance Digital Signal Processor to recreate sound fields artificially.

■ MATRIX

This mode reproduces a delayed signals from the surround channels to emphasize the sense of expansion for music sources.

■CHURCH

This mode provides the ambience of a church for baroque, string orchestral or choral group music.

THEATER

This mode provides the effect of being in a movie theater when watching a movie source.

HALL

This mode provides the ambience of a concert hall for classical music sources such as orchestral, chamber music, or an instrumental solo.

■STADIUM

This mode provides the expansive sound field to achieve the true stadium effect when watching baseball or soccer games.

• Before surround playback, first perform the speaker setup procedure, etc. on the SETUP menu for optimum performance. (For details, refer to "SETTING THE SPEAKER SETUP" on page 32.)
• Even when the auto surround mode is selected and the same type of digital signal format is being input, the optimum surround mode may vary depending on whether the speaker type is set to "N (None)" or not.
• When 96 kHz PCM digital signal is being input, only the stereo mode will be selected.

This mode extends the front stereo image to include the surround speakers for an exciting "wraparound" effect with side wall imaging.

Select "OFF" or "ON"(default value: OFF).

■ When selecting the "C. WIDTH (Center width)" control

This adjusts the center image so it may be heard only from the center speaker, only from the left/right speakers as a phantom image, or from all three front speakers to varying degrees.

The control can be set in 8 steps from 0 to 7(default value : 3).

■ When selecting the "DIMEN (Dimension)" control

This gradually adjusts the soundfield either towards the front or towards the rear. The control can be set in 7 steps from -3 to +3 (default value : 0).

■ When setting the distance

- You can set the distance within the range of 0.0 \~ 9.0 meters in 0.3 meter intervals (or 0 \~ 30 feet in 1 feet intervals).

1. Repeat the above steps 2 and 3 until the distances are all set as desired.

■ About the speaker distance

When enjoying multi-channel surround playback with Dolby Digital sources, etc., it is ideal that the center, surround and subwoofer speakers should be the same distance from the main listening position as the front speakers. By entering the distance between the listening position and each speaker, the delay times of center, surround and subwoofer speakers are automatically adjusted to create an ideal listening environment virtually as if the center, surround and subwoofer speakers were at their ideal locations respectively.

When selecting the CROSSOVER

- When speakers are set to "S (Small)", be sure to set their crossover frequency correctly according to their frequency characteristics.

1. Press the CURSOR UP(▲)/DOWN(▼) buttons to select the "X-OVER", then press the ENTER button.

- You can adjust the crossover frequency within the range of 40 \~ 200 Hz in 10 Hz intervals.

■ About the crossover frequency

• When speakers are set to "S (Small)", low frequencies in those channels that are below the crossover frequency are to output from subwoofer or front speakers which are set to "L (Large)" (when not using a subwoofer).
• Refer to the operating instructions of the speakers to be connected. If the frequency range of your speaker is 100 Hz\~20 kHz, the crossover frequency should be set to 100 Hz(or slightly higher).

SETTING THE CH LEVEL

■ Note : Depending on the speaker settings ("N (None or No)"), some channels cannot be selected.

Adjusting the current channel level

• You can adjust the current channel levels as desired. These adjusted levels are just memorized into user's memory("CAL"), not into preset memory ("REF 1", "REF 2")

• After adjusting each channel level with test tone, adjust the channel levels either according to the program sources or to suit your tastes. (For details, refer to "Adjusting each channel level with test tone" on page 17.)

• Press the CURSOR UP(▲)/DOWN(▼) buttons to select the desired channel.
