Surround Modes for Multi-Channel Sources

Surround Modes for Multi-Channel Sources

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 96/24 NEO:6

DTS 96/24 SUNFIRE

DTS-ES 96/24 MATRIX

DTS-ES 96/24 DISCRETE

Dolby Digital and DTS are “5.1” surround systems with ve 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 lls 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 lls 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 eld.

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.

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 nd 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 con g- 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 sound eld 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 lls 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.
