Adjusting the virtual 3D effect

The surround sound effect of the virtual 3D sound field is affected by the room configuration and the position of the listener,

resulting in sound unique to each environment. The procedure below shows you how to adjust the effect of the virtual 3D to

suit your preferences and environment.

Select the VIRTUAL tab at the bottom of the Main Panel. The following screen appears.

Adjusting the dynamic range

You can set the dynamic range for playing a source with Dolby Digital decoded. This is especially effective for low-volume

listening. Select the D-RANGE tab at the bottom of the Main Panel. The following screen appears.

Operating the graphic equalizer

The 7-band graphic equalizer allows you to set the frequency characteristics according to the type of the music that is played

and to compensate for the room characteristics and the speakers' frequency characteristics.

This panel is always shown when no DSP sound field program is selected. When a DSP sound field program is selected,

selecting the EQUALIZER tab at the bottom of the Main Panel will show this panel.

Balance adjustment

You can adjust the volume balance between the right

and left speakers.

Virtual rear speaker position setting

You can set the position of the virtual rear speakers

(the speakers are positioned symmetrically.)

HRTF (Head-related Transfer Function) adjustment

You can make an adjustment to personal

characteristics.

Test tone

You can output a test tone successively from the

speakers at their current positions, allowing setting and

adjustment while listening to the tone.

Dynamic range setting

Select the dynamic range for playing a source with

Dolby Digital decoded from MIN, STANDARD, and

MAX. The MAX setting provides a dynamic range of a

movie theater while MIN provides a dynamic range

suitable for late night, low-volume listening.

Dynamic range adjustment

This setting becomes available when you choose

STANDARD for the dynamic range. This adjusts high-

level cut scale (H-LEVELCut) and low-level boost scale

(L-LEVELBST), allowing you to freely adjust the

dynamic range between MAX and MIN.

Preset patterns

Five patterns of frequency characteristics have been

preset for different types of music, such as "ROCK" and

"POPS". Click a button to select the effect that suits

the music type.

Storing and calling user's patterns

You can store and call up to two patterns of frequency

characteristics you specify.

FLAT

This makes the frequency response curves flat.

Graphic equalizer

The 7-band equalizer allows you to set your desired

frequency response curves. By dragging the indicator

for each frequency band, you can adjust the

frequencies within the range of +6 to –6 dB.
