TONE CONTROL/VOLUME CONTROL
DESCRIPTION
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) .
FEATURES

1.Input only the control data at (1) INPUT DATA.
2.The interval of data transmission from the microcontroller is over
0.1 sec.This is waiting time for soft-switching to reduce the
