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

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

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).

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.
