Terminal Explanation
Input terminal.
Non-bias. It is possible to use with being directly connected
with DC. When DC coupling, it is necessary to add bias after
the coupling.
Equivalent Circuit
4 DCCNT1 DC offset mode charge terminal between input and output
13 DCCNT2 When a condenser is input at the position between pin 4
(DCCNT1) and GND, the operation of IC becomes the mode
with 0.3V DC offset between input and output of 1, 3, 4ch
(pins 3 and 33, pins 8 and 29, pins 12 and 14).
Similarly when a condenser is input at the position between
pin 13 (DCCNT2) and GND, it becomes the mode with 0.6V DC
offset between input and output of 2, 5, 6ch
(pins 6 and 31, pins 15 and 22, pins 17 and 20).
And when pins 4, 13 and GND is shorted, it becomes the mode
without DC offset between input and output.
5
GND
Both ±power supply and +power supply are GND.

MUTE1
Changeover terminal of Mute.
16
MUTE2
When the Mute terminal is Low, it is Mute.
When the terminal is Open, it is Low.
