MC-12

Designed for playback of 5.1-channel analog film sources.
Allows 7-channel playback of 5.1-channel analog sources
without THX Surround EX encoding.
Applies THX re-equalization to simulate high-frequency rolloffs
that occur in movie theaters. Most films are mixed for movie
theaters, and might sound too bright when played back in
home theaters without re-equalization.
Applies THX timbre matching to minimize timbre differences
between the front and surround channels, which results in
smoother sound movements between them.
Converts 5.1-channel analog input signals into digital audio for
internal THX processing.
Allows 5.1-channel analog sources to use bass management,
speaker crossovers, speaker distance calibration, and audio
controls (tone controls).
When THX Ultra2 decoding is engaged:
Applies adaptive de-correlation to increase the perceived width
of the listening space. De-correlation of the mono surround
channel increases the perceived width of the surround field in
home theaters.
Applies ASA processing to signals sent to the rear speakers.
Refer to the ASA parameter description on page 3-31 for more
information.
When THX Surround EX decoding is engaged:
Applies matrix decoding to derive three surround channels
from 5.1-channel analog sources.
