Customizing Sound Fields

By adjusting the surround parameters and the equalization of the front and center speakers, you can customize the sound fields to suit your particular listening situation.

Once you customize a sound field, the changes are stored in memory indefinitely (unless the receiver is unplugged for about one week). You can change a customized sound field any time by making new adjustments to the parameters.

See the table on page 38 for the parameters available in each sound field.

To get the most from multi channel

surround sound

Position your speakers and do the procedures described in “Multi-Channel Surround Setup” starting on page 16 before you customize a sound field.

Adjusting the surround parameters

The SURROUND menu contains parameters that let you customize various aspects of the current sound field. The settings available in this menu are stored individually for each sound field.

1Start playing a program source encoded with multi channel surround sound.

2Press CURSOR MODE repeatedly until the SURROUND indicator lights up.

3 Press the cursor buttons (

or

) to select the

parameter you want to adjust.

 

4 Press the cursor buttons (

or

) to select setting

you desire. The setting is entered automatically.

EFFECT LEVEL

Initial setting : (depends on sound mode)

This parameter lets you adjust the “presence” of the current digital cinema sound surround effect.

WALL TYPE

Initial setting : midpoint

When sound is reflected off soft material, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. This parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S) or harder (H) wall. The midpoint designates a neutral wall (made of wood).

REVERBERATION

Initial setting : midpoint

Before sound reaches our ears, it is reflected (reverberated) many times between he left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. This parameter lets you control the spacing of the early reflections to simulate a sonically larger (L) or smaller (S) room.

•The reverberation can be adjusted ±8 from S (small, –8) to L (large, +8) in 17 steps.

•The midpoint (0) designates a standard room with no adjustment.

LFE (Low Frequency Effect) MIX LEVEL

Initial setting : 0 dB

This parameter lets you attenuate the level of the LFE (Low Frequency Effect) channel output from the sub woofer without effecting the level of the bass frequencies sent to the sub woofer from the front, center or rear channels via the Dolby Digital (AC-3) bass redirection circuitry.

•The level can be adjusted in 1 dB steps from –20.0 dB to 0 dB (line level). 0 dB outputs the full LFE signal at the mix level determined by the recording engineer.

•Selecting MUTING mutes the sound of the LFE channel from the sub woofer. However, the low frequency sounds of the front, center, or rear speakers are output from the sub woofer according to the settings made for each speaker in the speaker setup (page 17).
