CHAPTER 5

For multi-channel sources, the

TGR-401 will automatically select the

correct mode from one of the follow-

ing:

DOLBY DIGITAL
DOLBY DIGITAL EX
DOLBY DIGITAL PLIIX MUSIC
DOLBY DIGITAL PLIIX MOVIE
DTS DIGITAL SURROUND
DTS NEO:6
DTS SUNFIRE
DTS-ES MATRIX
DTS-ES DISCRETE
DTS 96/24

DTS-ES 96/24 MATRIX
DTS-ES 96/24 DISCRETE

Dolby Digital and DTS are “5.1”

surround systems with five main chan-

nels: left front, center, right front, left

surround, and right surround. Each

channel can play the full frequency

range and is independent of the

other channels. The “.1” denotes the

subwoofer channel which plays the

low frequency effects (LFE), also inde-

pendent of the other channels.

Dolby Digital EX and DTS ES offer

"Extended Surround." Both systems

offer a surround back channel which

effectively fills in the otherwise empty

soundspace behind you.

If you want to try one of the modes

on the previous page, you should se-

lect a 2-channel output from your DVD

player's options menu.

NOTE: In your DVD player's audio

setup menu, set the digital output

to

BITSTREAM. If this is not set

correctly, the TGR-401 cannot

decode the digital information.

DOLBY DIGITAL

This mode is available if the

TGR-401 automatically detects a

Dolby Digital encoded source on

the currently selected input. You

should look for the Dolby Digital

Logo on DVDs, LaserDiscs and

other sources.
Many DVDs have the option of

a Dolby Surround, Dolby Digital

or Stereo soundtrack. Follow the

instructions in your DVD player's

manual to output Dolby Digital

bitstreams. Dolby Digital must

often be selected from the Disc's

menu.

DOLBY DIGITAL EX

Dolby Digital EX mode is primarily

for playback of Dolby Digital Sur-

round EX encoded soundtracks.

One advantage over Dolby Digital

playback is that it fills in the area

behind you with a completely

separate full-range channel.
The TGR-401 has the option of

connecting one or two surround

back speakers. The calibration

and speaker size options can cre-

ate a seamless surround field.
If you have no surround back

speakers, the extra information

is sent to the standard surrounds

and no material is lost. (Set the

surround back speakers to OFF in

the SPEAKER SIZE menu).
The TGR-401 will also create the

surround back channel if you are

playing a 5.1 source.

Surround Modes for Multi-Channel Sources

DOLBY DIGITAL with PRO LOGIC IIx

Besides Dolby Digital and Dolby

EX, you may change the Mode

to Dolby Pro Logic IIx Music or

Dolby Pro Logic IIx Movie. These

modes create enhanced stereo

surround backs. Listen to each

Mode to find which sounds best.
Dolby Digital uses a maximum

of 5.1 channels and does not

support surround back chan-

nels. Dolby EX supports a

mono

surround back channel (or

dual-

mono surround back channels if

both left and right surround backs

are used). Dolby Pro Logic IIx is

not an optional mode when the

surround back channel is config-

ured for only one speaker.
Dolby Digital plus Pro Logic IIx

Movie or Music uses the Dolby

Pro Logic IIx decoder to create a

stereo surround back soundfield

from the stereo content of the left

and right surrounds. For example,

Dolby Pro Logic IIx Movie directs

or "steers" some of the left sur-

round signal to the left surround

back, whereas Dolby Pro Logic

IIx Music lets the left surround

remain intact and fills in the left

surround back with additional

material.
Although movies are encoded

with either Dolby Digital or Dolby

EX, many sound even better

when using the Dolby Pro Logic

IIx modes.
