SYSTEM DESCRIPTION
The Shure UP Wireless System is a portable, frequency-agile, diversity wireless system operating in the UHF band. The UP4 receiver is easily
mounted to a Sony
R
video camera or any video camera with an Anton-Bauer
R
battery pack. The UP4 is compatible with both Shure UC and UHF
Series microphones and body-packs.
Both the receiver and the transmitter are microprocessor controlled by Phase Locked Loop (PLL) circuitry for a clear, steady signal. The following
components are available with the UP system:
UP4 Diversity Receiver with internal battery power supply, antennas, and camera-mounting hardware.
UC1 or U1 Body-Pack Transmitter with your choice of a WL93, WL184, or WL185 lavalier microphone.
UC2 or U2 Hand-Held Microphone-Transmitter with your choice of interchangeable microphone heads, including:
• SM58
cardioid dynamic microphone
• SM87 supercardioid condenser microphone
SYSTEM FEATURES
• UHF Band Operation. The Shure UP System operates within the UHF frequency band, which is less congested in metropolitan areas than
the VHF band. Typically, UHF systems encounter less interference than VHF systems.
• Frequency Agility. The UC and UHF-system transmitters’ and UP receiver’s frequencies can be changed to avoid RF interference. This
ensures interference-free operation, even in the most congested RF environments.
• Camera-Mountable Receiver Design. The UP4 receiver’s compact design allows easy mounting to Sony cameras and cameras outfitted
with Anton-Bauer battery packs. The UP4 receiver is supplied with hardware for mounting to cameras.
• Tone Key Squelch Circuitry. This circuitry prevents unwanted noise from entering the system, including the “pop” noise that occurs when
the transmitter is turned on or off.
• Noise Squelch Circuitry. This circuitry analyzes signal quality rather than signal strength, virtually eliminating the possibility of annoying
noise bursts.
• LED Indicators (On Receiver). Three LEDs provide information on audio level, RF level and battery power.
