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.
