Receiver Installation and Connections
Installation:
1.For 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.
2.Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the
shape of a “V” ( both 4 5°from vertical) for best reception.
3.Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles and
neon lights, as well as away from large metal objects.
4.Keep open space between the receiver and transmitter for better reception.
5.The transmitter should be at least 3ft. from the receiver.
Connections:
1.The 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 an IEC-type
input cordset approved for the country use. Power to the unit is controlled by the front panel power switch.
2.There 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 inputs. Use the
appropriate shielded audio cable for connections between the receiver and the input( s) of the mixer or other
equipment.
