Bryston SP1.7PRECISION - Manual (Page 30)

PLII Film This is the preferred decoding method for watching movies with matrix surround encoding.
The centre width and dimension variables are set and optimized for this application, and cannot
be adjusted. No filters are present on the surround channels, and autobalance is operational.
PLII Music This mode can enhance normal stereo music recordings, offering a wider soundstage and
enhanced spatial effects. This offers user control over the 1. Center Width, 2. Dimension and
3. Panorama. PLII Music also applies a mild high-frequency shelf filter to the surround channels
for a more natural soundfield. Autobalance is disabled.
1. Dimension Control. Allows the user to gradually adjust the soundfield either towards the front or towards the
rear. This can be useful to help achieve a more suitable balance from all the speakers with certain recordings.
2. Center Width Control. Allows variable adjustment of the center image so it may be heard only from the center
speaker, only from the left/right speakers as a “phantom” center image, or various combinations of all three
front speakers. For home users, it allows improved blending of the center and main speakers, or to control
the sense of image width, or “weight.”
3. Panorama Mode. Extends the front stereo image to include the surround speakers for an exciting “wrap
around” effect with side wall imaging.
