DIGITAL SOUND CONTROLLER WITH SURROUND
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.

Note1)The setting of ATT SW changes the input
resistance of D input like the following.
