C7-C0:Sets volume coefficient or delay coefficient
For the addresses of the registers their functions for Karaoke and movie & music programs, refer to the following
table and flow chart described in "
OPERATIONS" section.
For the relation between the setting value of coefficient, and volume level and delay time, refer to the formula
shown later.
When the coefficient registers controllable only in KP2V extended mode is used in the KP2 standard mode, the
following preset values are used as their coefficient of address, and their setting values are not used.
The values of the registers are indefinite immediately after turning on the power, be sure to set the register values in
the controllable mode before releasing the mute.
