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.

(4) Equivalent circuit of Vocal cut

This IC incorporates the circuit which realizes a vocal cut function simply by lowering gain in
the area using the mid circuit of the tone control.
But be careful because vocal cut ON setting,the mid of the tone control can not used.
