8-Channel 900 MHz Wireless Receiver
OWNER’S MANUAL — Please read before using this equipment.
Your RadioShack 8-Channel 900 MHz Wireless Receiver is designed for use as a universal microphone receiver for public address
microphones or for professional music performances. The system’s long range (200 feet),
UHF operation (910–921.5 MHz), and low distortion (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 le vel 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 outputs with other sound sources.
