Enjoying Surround Sound

Selecting a Sound Field

You can enjoy surround sound simply by selecting one of

the pre-programmed sound fields according to the

program you want to listen to.

1 Press SOUND FIELD MODE.

The current sound field is indicated in the display.

2 Turn the jog dial or press the cursor buttons

(

or ) to select the sound field you want.

See the table starting on page 32 for information on

each sound field.

To turn the sound field off

Press A.F.D., 2CH or MULTI/2CH A. DIRECT (page 33).

Tip

When sound signals with a sampling frequency of 96 kHz are

input, the sound signals are output in stereo automatically, and

the sound field is turned off.

You can identify Dolby Surround-encoded software by

looking at the packaging

Dolby Digital discs are labeled with the logo, and Dolby

Surround encoded programs are labeled with the A

logo.

6.1 channel matrix decoding

Some movies released after the summer of 1999 added a new

channel to its preexisting 5.1 channel. The new channel added

speakers behind the listening position. In the movie theaters,

these speakers are placed on the rear wall, on each side of the

projection room’s window.

The 6.1 channel system used in the movie theaters is called Dolby

Surround EX system. However, to record on movie films, this 6.1

channel is converted to 5.1 channel using matrix encoding, and

the same number of channels are used as Dolby Digital and DTS

recordings. Recordings on the DVD also use the same signals.

A lot of movie theaters screen movie with matrix encoded

5.1 channel signals and this is not unnatural to the ears. However,

when a matrix decoder is used to create surround center speaker

signals, this simulates the same 6.1 channel sound as Dolby

Surround EX system in the movie theaters.

This unit is equipped with the matrix decoder allowing for 6.1

channel sound production. With Virtual 3D technology, the

surround back signals can be enjoyed even without an actual

surround back speaker. When the center speaker is not used, it is

possible to use this channel to output surround back signals.

Particularly with 6.1 CH DECODING, speakers placed on rear

and side walls in the movie theaters are virtually created. As

reflections and reverberations are also simulated, you can enjoy

powerful sounds as if in the movie theater that uses Dolby

Surround EX system.
