1, Receiver Installation and Connections
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 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 inputs. Use the
appropriate shielded audio cable for connections between the receiver and
the input(s) of the mixer or other equipment.
