3.10.4 Auxiliary Feedback: Pulse-and-Direction Input Option (YA[4]=0)

Pin Signal Function Pin Position

J1/28 COMRET Common return

J1/5 DIR/CHB Direction input (push/pull 5 V or

open collector)

J1/4 PULS/CHA Pulse input (push/pull 5 V or open

collector)

Note: The Guitar’s Auxiliary Feedback is single-ended.

When mounted on an integration board, circuitry can be

added to make it differential.
