MITSUBISHI SOUND PROCESSORS
M61500FP
TONE CONTROL/VOLUME CONTROL
DESCRIPTION
The M61500FP is the sound controller powerd by "QSurround" system.
The "QSurround" system decodes and virtualize multi-speaker surround
sound from various matrix surround encoded sources:
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 producted under license from QSound Lab,Inc.(Canada) .
FEATURES
Built-in "QSurround" sound technology
Electronic volume.
0 ~ -84dB, infinitesimal
2-band tone control
Bass(0 ~ +21dB/3dB STEP)
Treble(0 ~ +9dB/3dB STEP)
5 input selector(The fifth input can be used as REC OUT or MIC MIX.)
RECOMMENDED OPERATING CONDITIONS

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
shocknoise.
3.It's necessary to set up the all control data after poweron,although the internal circuit is forced as belows,when (VDDVSS)<3.3V(TYP).
