MITSUBISHI SOUND PROCESSORS
M61509FP
TONE CONTROL/VOLUME CONTROL
DESCRIPTION
The M61509FP is the sound controller powered by the "QXpander" system.
The "QXpander" system produces normal and wide 3D sound expansion
from any stereo input signal.
(Note) This device is produced under license from QSound Lab,Inc.(Canada) .

(2) NOTICE OF CONTROL DATA
1.use only the control data of (1) INPUT DATA .
2.The interval of data transmission from the microcontroller is over
0.1 sec.: This is the waiting time for the "soft-switching"
to reduce the shock noise.
(The "soft-switching " is available at the volume and
QXpander.)
=
<NOTE>
(1) The "Slot1" and the "Slot2" are independent data.
Each data need each waiting time.
(2) The some function of the volume and other function
have no "Soft-Switching".
<Example 1>
When the volume is set as " infinitesimal", it's
immediately attenuated (but,it needs the waiting time
to reach the final attenuation).
<Example 2>
The change of tone control is immediately executed.
3.It's necessary to set the all control data after power-on,
although the internal circuit is forced as below,when (VDDVSS)<3.3V(TYP).
