Customizing Sound Fields

By adjusting the surround parameters and the equalization of the front, rear 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 the memory indefinitely (unless the receiver is unplugged for about two weeks). You can change a customized sound field any time by making new adjustments to the parameters.

See the table on page 41 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 from page 18 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 SURROUND.

The button lights up and the first parameter is displayed.

3 Press the cursor buttons ( or ) to select the parameter you want to adjust.

4Turn the jog dial to select the setting you desire. The setting is entered automatically.

6.1ch Matrix (6.1 MATRIX)

Initial setting : AUTO

This parameter can be used when NORMAL SURROUND is selected. According to the setting, the receiver decodes and downmixes the rear center signal to the rear L/R speakers for 6.1 channel encoded sources. This parameter lets you enjoy the appropriate surround sound from the rear channels.

•When set to “AUTO”, the receiver performs 6.1ch MATRIX decoding only if 6.1ch signals decode flag is ON.

•When set to “ON”, the receiver performs 6.1ch MATRIX decoding only if the rear signals are 2channel, regardless of the 6.1ch decode flag.

•When set to “OFF”, the receiver does not perform 6.1ch MATRIX decoding.

Pro Logic (PRO LOGIC)

Initial setting : AUTO

This parameter lets you specify the Pro Logic decoding setting.

•When set to “AUTO”, the receiver performs PRO LOGIC decoding if Dolby surround encoded flag is ON or if Pro Logic decoding produces a better sound field.

•When set to “ON”, the receiver performs PRO LOGIC decoding on rear signals, regardless of the Dolby surround encoded flag.

•When set to “OFF”, the receiver does not perform PRO LOGIC decoding.

Effect level (EFFECT)

Initial setting : (depends on sound mode)

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

Wall type (WALL)

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).
