1. Important Caution
2. Features
Always make all connections before plugging the unit into an AC power outlet.•
Do not leave the devices in a place neither with high temperature nor high humidity.•
Always do not handle the power cord with wet hands !•
Keep the devices away from re and heat sources.•
Operated in UHF band where there is less RF interference than the VHF band.•
Due to the PLL synthesized technology, the system can oer up to 961 selectable frequencies for•
choosing simultaneously.
e true diversity reception with 2 independent RF receivers ensure the stable transmission and•
reception.
Adjustable Pilot tone squelch control can eectively reduce the noise.•
Equipped with S.A.W. lter benets the interference-resistant.•
Tuned antennas can benet the stable RF reception.•
Built-in Noise Squelch circuity & Mute function are available to restrain the interference for•
signals.
Compact half-rack receiver design is considerable for the space saving.
•
Rugged metal housing can pass through the dicult environment.•
Equipped with balanced XLR and unbalanced output allow great convenience.•
Anti-interference design is available to work with every computer device.•

5. Preparing Procedures & Basic Operation
5-1 Receiver // US-901D
(1) Power output connector
Plug in one end of AC/DC adaptor cable to DC input socket in the rear panel of receiver, and
plug another end into an AC outlet.(Step 1)
(2) Audio Output Connector
Connect one end of the AF output cable to the AF output socket in the rear panel, then plug
another end to the “MIC IN” input socket of a mixer or amplier.(Step 2)
Receiver equipped with balanced XLR output and Unbalanced φ6.3mm output, choose the
proper way for use.

Four self-adhesive rubber pads are provided
to ensure the stability.
ey are to be placed on the boom side of
the receiver.
(5) Connecting the antennas
e user-friendly receiver antenna comes
with easy mount on socket for eortless
connection. Connect two antennas on the
back of the receiver and align them upward.
(6) Connecting the main unit
Plug in the DC connector on the back of the
receiver (DCV INPUT).
(7) Connecting the amplier/mixer console
Plug in the amplier/mixer console to the
(AF OUT UNBAL / BAL ) sockets.
