SETTING
Surround of outside setting, it becomes "D54=1"--->Sw41 and 42 setting = B fixation. Surround of inside
setting ( Surround of outside non setting), It becomes "D54=0"--->Sw41 and 42 setting = A fixation.
Note1)
Note2)In power supply investing to Mute an output in, It becomes setting like the following. Input selector = ALL
OFF, Outside surround mode setting, REC-A,B SW=OFF,B1 main volume= - ¥ setting. The similar MUTE
setting can be done by setting D34=D54=1.
Note3)
It is impossible to use the vocal cut and the inside surround function, First. it sets the vocal cut ON after
setting the inside surround ON, in case of switching to the vocal cut ON setting from the inside surround
ON setting. And it sets the inside surround ON after setting the vocal cut On, in case of switching to the
inside surround ON setting from the vocal cut ON setting.

FUNCTION DESCRIPTION
(1)Main volume
This IC has 2 system independence electron volume of low warp percentage and low noise.
0dB~ -¥ dB attenuation quantity can be set with 36 steps(0dB~ -44dB:2dB step,-44dB~ -76dB:4dB step,
-77dB ~ -80dB:1dB step).
The attenuation quantity to 0~ -16dB can be set in A1 Vol.
The attenuation quantity to 0~ -64dB can be set in B1 Vol.They are possible to control.

(2)Input selector,Input volume
This IC has 4 input selector of 2ch and Input volume of 2ch for Input TRIMMER.
The input selector D input is either of -8 dB of 0dB/ a choice in the input level with ATT SW.
The input volume of 0~-14dB can be set with the 2 dB step.

(4) Equivalent circuit of Vocal cut
It removes the vocal cut from usual music source (the stereo).
It centers on the vocal cut by the fixed rank, it is inputted to L,Rch in the same phase and
the same amplitude. Therefore, it comes in the vocal cut by L-R setting.

Lowpass filter for Vocal cut
Note1) Vocal cut output is monaural.
Note2) In the setting which uses the vocal cut, the inside surround function can't be used.
Note3) In setting of the vocal cut use, the output sometimes does a clip in the low area
part, when inputting a signal above Vin=0.6Vrms.

It fixes (fo) of the low cut off frequency in 20KWof the
inside resistance and Cv of the outside capacitor. It shows
by the formula below.
