Right channel high mid band control block.

External capacitor connections.

Right channel high band control block.

External capacitor connections.

Internal filter DC offset voltage exclusion capacitor connections.

Capacitors of about 10 µF must be connected between pins 61 and 62, and between pins 63 and 64.

(These are for the left channel block.)

Internal filter DC offset voltage exclusion capacitor connections.

Capacitors of about 10 µF must be connected between pins 51 and 52, and between pins 49 and 50.

(These are for the right channel block.)
