Introduction
Installation:
①For better operation the receiver should be at least 3ft. 1m above the ground and at least 3ft.
away from a wall or metal surface to minimize reflections.
②Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the
shape of a “V” (both 45°from vertical) for best reception.
③Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles
and neon lights, as well as away from large metal objects.
④Keep open space between the receiver and transmitter for better reception.
⑤The transmitter should be at least 3ft. from the receiver.

Connections:
①The switching power supply is designed to operate properly from any AC power source 100-240V,
50/60Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only
50/60Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only
an IEC-type input cordset approved for the country use. Power to the unit is controlled by the front panel
power switch.
②There are two audio outputs on the rear panel: an XLR microphone output and a 1/4” (6.3mm) phone
jack instrument output. The two isolated audio outputs permit simultaneous feeds to two different
