TEXO_2MB - THX Surround EX™ 5.1

Channel Post-Processor offers all of the post-

processing features of the TEX code, however

TEXO_2MB also offers extended all channel

delays (up to 221ms on all channels).

Note: The tone control includes basic bass and treble

control for each full bandwidth channel, including

Surround Back channel. The parametric EQ can

not be changed after kickstart. Delays are all

channel. A 2MBit External SRAM (70nS) is

required to be connect to the CS49330 in order

for this code to function. Surround EX decoding

should only be enabled when material is Dolby

Surround EX encoded. Please refer to AN163H

for more information about the THX Surround EX

5.1 Channel Post-Processor code.

TEX8 - THX Surround EX™ 7.1 Channel Post-

Processor offers all of the post-processing

features of the THX8 code, however TEX also

offers the Surround EX module. The Surround

EX module performs a matrix decode on Ls and

Rs, using a Dolby Pro Logic decoder in 3

Channel Stereo mode, to create an additional

back surround channel. This surround back

channel is then copied to the output channels of

Sbl and Sbr in order to give a 7.1 channel

output. TEX8 differs from the TEX code in the

sense that it can post process multichannel

sources that have more than 5.1 discrete

channels, such as DTS-ES Discrete 6.1

streams.

Note: The tone control includes basic bass and treble

control for each full bandwidth channel, including

Surround Back channel. The parametric EQ can

not be changed after kickstart. Delays are all

channel. Surround EX decoding should only be

enabled when material is Dolby Surround EX

encoded. Please refer to AN163O for more

information about THX Surround EX 7.1 Channel

Post-Processor code.

TEXO8 - THX Surround EX™ 7.1 Channel

Post-Processor offers all of the post-processing

features of the TEX code, however TEXO8

also offers extended all channel delays (up to

105ms on all channels).

Note: The tone control includes basic bass and treble

control for each full bandwidth channel, including

Surround Back channel. The parametric EQ can

not be changed after kickstart. Delays are all

channel. A 1MBit External SRAM (70nS) is

required to be connect to the CS49330 in order

for this code to function. Surround EX decoding

should only be enabled when material is Dolby

Surround EX encoded. Please refer to AN163O

for more information about the THX Surround EX

7.1 Channel Post-Processor code.
