DCCNT1 DCCNT2
DC offset mode charge terminal between input and output 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.

GND
Both ±power supply and +power supply are GND.
MUTE1 MUTE2
Changeover terminal of Mute. When the Mute terminal is Low, it is Mute. When the terminal is Open, it is Low.

Using ±power supply, in case of the mode with DC offset, it is possible to use without capacitor of output by setting pins 3, 8, 12 to 0.3V-bias and by setting pins 6, 15, 17 to 0.6V-bias. And in case of the mode without DC offset, it is possible to use without capacitor of output by setting each input to zero-bias. When using +power supply, both of the modes needs coupling capacitor. Pin Name –VCC. Terminal Explanation –VCC of using ±power supply. Using +power supply, it is GND. Equivalent Circuit
