8-Channel 900 MHz Wireless Receiver
Your RadioShack 8-Channel 900 MHz Wire-
less Receiver is designed for use as a univer-
sal microphone receiver for public address
microphones or for professional music perfor-
mances. The system’s long range (200 feet),
UHF operation (910–921.5 MHz), and low dis-
tortion (2.0%) let you use it anywhere you
would use a conventional microphone, and is
perfect for use with the RadioShack 8-Channel
900 MHz Wireless Microphone (RadioShack
Cat. No. 32-1251). The microphone receiver
has both LINE and MIC level outputs for easy
connection to any amplifier, mixing board, or
recorder. Plus, you can use both outputs at
the same time. The receiver’s volume control
lets you easily balance the microphone’s out-
puts with other sound sources.
You can mount the microphone receiver on an
optional Rack Mountable Accessory (Ra-
dioShack Cat. No. T32-H010001/12252664),
then mount the receiver and accessory on a
rack. See the Rack Mountable Accessory’s
owner’s manual for more information.
If you use a rack to mount your microphone re-
ceiver, you can connect an external antenna
(RadioShack Cat. No. T32-T450/12313912)
for better reception. Connect the antenna’s
BNC plug to the BNC socket on the rear panel
of your receiver, then place the antenna base
in the open site. (The antenna base is a mag-
netic material and can be attached on the
steel surface).
