Dsp Presets And Layouts - Meridian 861 User Manual

INTRODUCTION PREFACE

DSP presets and layouts

The 861 provides an extensive range of options for decoding and
processing analogue and digital signals for multichannel reproduction.
Music on CD or radio
The following DSP presets add a surround dimension to stereo recordings,
such as on audio CDs or FM radio.
Music extracts the mono and surround components of the original
recording for the centre and surround speakers to give a spacious open
sound fi eld.
Trifi eld is similar to Music but generates a centre-front signal that is
completely integrated with the front stereo image, for a more stable,
accurate, and focused stereo image. The image width is also adjustable.
Super produces a very good surround effect with many live recordings.
PLIIx Music and Music Logic are recommended for use with studio
produced music, and provide different options for adjusting the sound
fi eld.
Two-channel movie soundtracks on DVD, video, and TV
Many movie soundtracks are Dolby Surround Encoded onto a two-channel
stereo soundtrack.
The following DSP presets re-create the surround components from this
type of material:
PLIIx Movie is Dolby's recommended choice for Dolby Surround Encoded
material, and PLIIx THX provides a variant of this better suited to home
listening.
TV Logic uses the same processing techniques as PLIIx Movie but with
adjustable steering to give better results with TV material.
Special presets for two-channel materials
Direct uses only the left and right speakers; compare this with the effect of
surround processing using the other modes. Stereo will use a subwoofer if
it is present.
Ambisonics is specially designed for two-channel materials that are UHJ
Ambisonically encoded, such as certain audio CDs. The encoded surround
information is recovered and played back using all the loudspeakers in your
system. In addition it will give impressive results with other two-channel
material.
