PRELIMINARY
Notice : This is not a final specification.
some parametric limits are subject to change.
The M61515FP is the sound controller powered by "QSurround" system.
The "QSurround" system decodes and virtualizes multi-speaker surround
sound from various matrix surround encoded sources such as:
Dolby Surround, stereo downmixed AC-3, stereo downmixed DTS.
Produces normal and wide 3D sound expansion from any stereo
input signal.
(Note) This device is produced under license from QSound Lab,Inc.(Canada) .
Built-in "QSurround" sound technology
