Note3) At the time of input selector A~C, E or ALL OFF
ATT SW becomes -8dB setting.
D input ATT SW becomes -8dB setting.
At the time of input selector A~D or ALL OFF D input
(2)Input selector,Input volume
The input selector D, E 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.
(1)Main volume
0dB~ - dB attenuation quantity can be set with 36 steps(0dB~ -44dB:2dB step,-44dB~ -76dB:4dB step,
-77dB ~ -80dB:1dB step).
This IC has 5 input selector of 2ch and Input volume of 2ch for Input TRIMMER.
This IC has 2 system independence electron volume of low warp percentage and low noise.
The attenuation quantity to 0~ -64dB can be set in B1 Vol.They are possible to control.
The attenuation quantity to 0~ -16dB can be set in A1 Vol.
