TV Logic
TV Logic
provides user-adjustable steering, and is
recommended for use with TV broadcasts that are not surround
encoded, where
Pro Logic
may give reduced intelligibility.
THX Cinema
THX
Cinema
enhances
Pro Logic
to replicate the sound of a
dubbing stage or theatre, whether or not the other equipment in
your system is THX approved.
Ambisonic
Ambisonic
decodes material specifically encoded for surround
sound reproduction, using a two-channel stereo-compatible
encoding. Recordings encoded in Ambisonic format are
available on CD from several sources including Nimbus Records
and York Ambisonic. Some radio broadcasts are also broadcast
in Ambisonic format.
Conventional stereo sources
The digital surround processor can also accept a conventional
two-channel source, such as music on compact disc or a video
soundtrack, and by analysing the information in the signal
separate the two-channel recording into multiple channels to
give better reproduction and a more stable spatial image.
Four alternative DSP presets are provided for reproducing
material originally designed for a conventional stereo pair of
speakers, and which preset you choose largely depends on your
own personal preferences.
All four presets use similar procedures to extract the surround
component of the original recording, which is delivered to the
rear surround speakers, and side surround speakers if present.
Music
Music
uses a special technique developed by Meridian to divide
the sound between the left, right, and centre speakers and give
a wide, spacious sound. We recommend this option for large-
scale music, such as orchestral and choral music.
