Introduction
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.
Trifield
Trifield uses a different processing technique to give a stable,
three-dimensional image, with the ability to adjust the width of
the image. Because of its precision we recommend this option
for solo, chamber, or vocal music.
Super Stereo
Super Stereo provides a form of Ambisonic decoding suitable for
material that is not specially encoded. We recommend this option
for multi-miked or multi-tracked music, such as rock music.
PLII Music
PLII Music uses the Pro Logic II DSP processing mode to
decode music sources, and provides for user-adjustable
steering to give an exciting sound with many types of music. We
recommend this option for studio-produced music, ie material
not produced using natural soundfield recording.
Special DSP presets
The digital surround processor also includes the following
special DSP presets, for specific applications:
Mono
The Mono preset is designed for reproducing mono materials
through a centre speaker, so that any high-frequency hiss or
clicks are centrally localised. It is intended for mono recordings,
and multi-language LaserDiscs and video soundtracks.
The Mono preset includes an Academy option, designed to
correct for a high-frequency balance in some old black and
white films, and a Party option, which plays the mono signal
through all loudspeakers.
Stereo and Direct
Stereo and Direct are provided for comparison with the other
DSP presets. Direct uses just the main left and right speakers for
traditional two-speaker stereo reproduction. Stereo, in addition,
uses any subwoofers in the layout to enhance the bass or to
protect small speakers.
