33 LTOUT Equalizer output terminal.
16 RTOUT
32 LFIN The fader block input terminal.
17 RFIN Drive by low impedance.
31 LFOUT The fader output terminal.A rear reception desk side / side can be separately narrowed
30 LROUT respectively.
18 RFOUT L/R of the amount of attenuation is the same.
19 RROUT
57 Vref VDD/2voltage generation part.
Connect the capacitor of about several 10 F as a counter measure for ripple of power
supply between Vref~AVSS for (VSS).
56 VDD Power supply terminal.

29 LAVSS Analog grand terminal.
22 RAVSS
23 MUTE External control mute terminal.
When this terminal is made VSS level,fader volume block is set in compulsory-
20 TIM Timer terminal at no signal of 0 crossing circuit.
26 CL Cereal data and clock input terminal for control.
25 DI
24 CE chip enable terminal.
[H]data is written in an internal latch in the timing which becomes
each switch moves.[H] The data transfer becomes enable at the level.
