APPENDIX A: HARDWARE INTERCONNECTION DETAILS
The output may be set for either balanced (push-pull) or
unbalanced operation. In the unbalanced configuration,
pin 3 of the output connector is grounded, and the maxi-
mum output level drops by 6 dB.
To operate the output unbalanced, you must follow this
procedure; Remove the unit's top lid. Locate the configu-
ration jumper block next to the output connector. The
jumper is factory-installed in the balanced position.
Observing the positions marked on the circuit board,
remove the jumper and reinstall it in the unbalanced
position.
On the output XLR, IN THE UNBALANCED MODE
ONLY, use pin 2 as "HOT" and pin 3 as "COMMON.” Pin
1 is to be used as "SHIELD.”
