Surround Sound Tab

This tab controls the surround sound features of the Sonica Theater.There

are two SRS Labs technologies included with the control panel,TruSurround

XT and Circle Surround II. TruSurround XT takes a multi-channel source

and plays it through two speakers in a way that makes it sound like you’re

playing it back through multiple speakers. Circle Surround II takes a stereo

source and processes that so that it plays through multiple speakers.

Here’s a suggested guide to playing surround sources through your

Sonica Theater:

• If you’re playing a 5.1 DVD with WinDVD 4 (Windows only), and

you have multiple speakers attached, Circle Surround II should

be unchecked.

• If you’re playing a 5.1 DVD and you only have two speakers

connected, turn on TruSurround XT.

• If you’re playing a stereo MP3, CD, or DVD and want to hear it

through multiple surround channels, turn on Circle Surround II.

The TruSurround XT settings only appear if your Current Speaker Set is

set to “Stereo”, “Stereo w/Integrated Subwoofer”, or “Headphones”. The

Circle Surround II settings only appear if your Current Speaker Set is set

to three or more channels.

SRS TruSurround XT Enable - This control turns on the TruSurround

XT feature.TruSurround XT “virtually” places individual surround channels

where they are supposed to be, as though you have speakers all around

you. Use this feature to turn 5.1 or 6.1 multi-channel sources, such as

Dolby Digital or DTS encoded DVDs, into “virtual” surround from your

stereo speakers.

NOTE: Circle Surround II will not work at 96kHz, when using this

feature the Sampling Rate must be set to 48000Hz or lower. (See the

section following.)

SRS Circle Surround II Enable - This control turns on the Circle

Surround II feature. Circle Surround II is a patented SRS technology that

solves the problem of playing 5.1 multi-channel content from a two channel

source. It delivers a compelling, virtual surround sound experience through

any multi-channel playback system. It is fully compatible with all

multi-channel formats up to 6.1 channels. Use this feature to turn stereo

sources, such as CDs, MP3s or Dolby Pro Logic encoded DVDs, into 6.1

multi-channel surround.You’ll want to turn this feature off if you’re listening

to a source that’s already playing back in 5.1 or 6.1, such as Windows Media

or a DVD movie.
