THX - Home THX Cinema™ 5.1 Channel Post-

Processor offers: Re-Eq™, Timbre Matching™,

Adaptive Decorrelation™ THX Bass Peak

Limiter™,

Loudspeaker

Position

Time

Synchronization™ (all-channel delays), in

addition to tone control and parametric

equalization.

Note: The tone control includes basic bass and treble

control for each full bandwidth channel, including

Surround Back channel (Sb). The parametric EQ

can not be changed after kickstart. Delays are all

channel. Please refer to AN163H for more

information about the Home THX Cinema 5.1

Channel Post-Processor code.

THX8 - Home THX Cinema™ 7.1 Channel

Post-Processor

offers:

Re-Eq™,

Timbre

Matching™, Adaptive Decorrelation™ THX

Bass Peak Limiter™, Loudspeaker Position

Time Synchronization™ (all-channel delays),

in addition to tone control and parametric

equalization. THX8 differs from the THX 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 (Sb). The parametric EQ

can not be changed after kickstart. Delays are all

channel. Please refer to AN163O for more

information about the Home THX Cinema 7.1

Channel Post-Processor code.

TEX - THX Surround EX™ 5.1 Channel Post-

Processor offers all of the post-processing

features of the THX 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.

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 AN163H for more

information about the THX Surround EX 5.1

Channel Post-Processor code.

•

TEXO - THX Surround EX™ 5.1 Channel

Post-Processor offers all of the post-processing

features of the TEX code, however TEXO 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 AN163H

for more information about the THX Surround EX

5.1 Channel Post-Processor code.
