• Use a cable with a female XLR connector and TS jack plug:
1. On the XLR connector, use a wire bridge to connect pin 1 to
pin 3 and the cable shield.
2. Connect the inside wire of the cable to pin 2 on the XLR
connector and the tip contact of the jack plug.
• Unbalanced cables may pick up interference from stray
magnetic fields near power or lighting cables, electric mo-
tors, etc. like an antenna. This may introduce hum or simi-
lar noise when you use a cable that is longer than 16 feet
(5 m).
