CHAPTER 5

Surround Modes for Multi-Channel Sources

For multi-channel sources, the TGP-5 will automatically select the correct mode from one of the follow- ing:

DOLBY DIGITAL

DOLBY DIGITAL EX

DTS

DTS-ES MATRIX

DTS-ES 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 TGP-5 cannot de- code the digital information.

DOLBY DIGITAL (5.1)

This mode is available if the TGP-5 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 (6.1/ 7.1)

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 TGP-5 has the option of con- necting one or two surround back speakers. The calibration and speaker size options can create 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 TGP-5 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 during Dolby Digital playback us- ing the Mode keys on the remote or front panel, to Dolby Pro Logic IIx Music and Dolby Pro Logic IIx Movie. These two modes create enhanced stereo back surrounds. Listen to each Mode to determine which sounds best on a given movie.

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 Movie is not an optional mode when the surround back channel is configured 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. Try it out.

DTS (5.1)

This mode is available if the TGP- 5 automatically detects that a DTS encoded source is present at one of it’s digital inputs. Look for the DTS Logo on DVDs, LaserDiscs, CDs and other sources.

Make sure that you set your player to output DTS bitstreams. DTS must also be selected on the disc's menu.

DTS ES (6.1)

All DTS-ES sources have the surround back channel matrixed in the left and right surrounds. Newer DVD releases also have a discrete surround back channel, in addition to the same information matrixed.

DISCRETE ES sources: the TGP-5 DTS-ES discrete decoder will decode the discrete surround back channel. It also removes the surround back matrix from the left and right surrounds, and restores them to be fully independent channels.

MATRIX ES sources: If there is no discrete surround back channel, the TGP-5 decodes the matrixed surround back channel from the left and right surrounds, and restores them to be fully indepen- dent channels.
