•Unpack the box. Screw the dual antennas into the
connectors on each side of the front panel of the
receiver unit. Point them both upward in a vertical
position.
•Use the provided 1/4-inch cable to connect the
UHF-4000R receiver from the 1/4-inch Unbalanced
Audio Output to the “Mic In” on your ampli er,
mixer or player. Alternatively on a multi-channel
mixer, use the four optional XLR output ports on the
back of the receiver. Use 1/4-inch XLR cables* to
connect the microphones. *Cables not included.
•Plug the power adapter into an AC outlet.
Press ON “1” on the power switch. All four channel
Power LEDs should light up RED. If any micro-
phones have been left on and are in range, their cor-
responding receiver RF LEDs will light yellow.

a console or rack by using the provided rack-mount
brackets. Make sure holes are aligned and screwed
with even tension.
Cable Connections & Operating the Microphone System

dual base charging station. Each status LED on the
charging station will light up RED to indicate a good
connection and that the batteries are charging. Al-
low the batteries to charge fully before removing the
microphones from the charging station.
