GND
Terminal for holding the audio
VCC output DC level fixed.
Connect to GND via a 4.7µF
capacitor and to Vreg via a 10µF
3.5V
capacitor to reduce BUZZ.

2nd SIF output.
Connect a Trap to this pin to vary
the Sound Filter characteristics.
The internal impedance is a high
(Approximately) 1kΩ, so connect a
Buffer to output.
