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. 14 23 32 7 MUTE1 Changeover terminal of Mute. 16 MUTE2 When the Mute terminal is Low, it is Mute.
