Q: How do I use the FP-Audio on VA-10 v 1.3.(VA-10/VA-11)
A:

To use the audio connector at front pane, please remove the jumps on pin 5-6 & 9-10, and than connect to front pane by the extension cable provided with the chassis or case. If would use the rear audio connector, please disconnect the extension cable, and attach the jumpers back on pin 5-6 & 9-10 (default setting).
