Explanation of Functions
(1) Main volume
This IC includes two independent low-distortion, low-noise electronic volume systems. The attenuation can be set from
0 dB to -∞ dB in 1 dB steps.
Also, the attenuation can be set between 0 and -16 dB for the first stage, and between 0 and -64 dB for the second stage,
and both can be controlled independently.

(2) Input selector, input volume
Two channels of 5-input selectors, and two channels of input volume controls for input trimmers, are incorporated. The
D and E inputs of the input selectors can select either 0 dB or -8 dB input levels for an input resistance of 12 kΩ using
the ATT switch. The input volume can be set between 0 and -14 dB in 2 dB steps.

Note 2) When the input selector is A-C or E or is ALL OFF, the D input ATT SW
is set to -8 dB. When the input selector is A-D or is ALL OFF,
the E input ATT SW is set to -8 dB.
Note 3) The D and E input ATT amounts shown are the values when a D and E input resistance
Rin=12 kΩ is connected.
Note 4) When the external 12 kΩ resistance is eliminated, the D and E input ATT amounts are set as follows.
0dBsetting: 1.87dB
-8dBsetting: 0dB
