Common Features

Compact, Lightweight, and Robust Design

All components of the UWP Series – the bodypack transmitter, handheld microphone, plug-on transmitter, portable receiver, and tuner module – utilize an extremely robust metal chassis, which is ideal for heavy-duty wireless operations. The metal body also allows for an extremely compact and lightweight design, providing the high level of mobility required for ENG and EFP operations. What’s more, the black body complements Sony’s professional camcorders extremely well.

Stable Transmission and Reception

The UWP Series Wireless Microphone Package uses three core technologies to provide stable transmission and reception:

PLL Synthesized System

The UWP Series employs a UHF PLL (Phase Locked Loop) frequency synthesized system, which provides a stable carrier signal that helps to avoid interference with other frequency channels and allows for easy access to multiple frequencies. The PLL-controlled system provides highly stable, user-selectable frequencies in increments of

125 kHz. Users can choose from 188 frequencies on U models, 189 frequencies on CE models, and 102 frequencies on AU models.

Space Diversity Reception System

Typically, wireless microphone transmission systems can be subject to interruptions in reception (signal dropout), but the UWP Series reduces this to a minimum. Utilizing a space diversity reception system, it achieves stable reception by using dual-antenna inputs/reception circuits. These receive signals over two different paths and automatically select the stronger RF signal for output. The angle of the antennas on the portable receiver can also be adjusted, which helps to further eliminate signal dropout.

Tone Squelch Circuitry

The UWP Series transmitters transmit a 32-kHz pilot-tone signal along with the audio signal. The tuner’s squelch circuit recognizes this tone signal, and outputs the audio signal only when this tone signal is received. This function virtually prevents the output of unwanted signals and noise from other signal transmissions in the air, as well as the

RF noise and popping noise that occur when the transmitter is powered on or off.

Pre-programmed Operating Frequencies

The transmitters and tuners included in the UWP Series incorporate groups of intermodulation-free preprogrammed frequencies that have been carefully calculated and practically tested. By selecting from these preprogrammed frequency groups, users can quickly and easily operate up to 16 wireless microphones simultaneously.

The UWP Series operates within the following frequency ranges:

Operating frequencies			Selectable
			frequencies
U model	U3032	566 MHz to 590 MHz	188 (in 125-kHz steps)
		(TV 30 to 33 channels)
	U4244	638 MHz to 662 MHz	188 (in 125-kHz steps)
		(TV 42 to 45 channels)
CE model	CE62	798 MHz to 822 MHz	189 (in 125-kHz steps)
		(TV 62 to 64 channels)	/960 (in 25-kHz steps)
	CE67	838 MHz to 862 MHz	189 (in 125-kHz steps)
		(TV 67 to 69 channels)	/960 (in 25-kHz steps)
AU model	AU66	792 MHz to 806 MHz	102 (in 125-kHz steps)
		(TV 66 to 67 channels)

Auto Channel Scanning Function

The URX-P2 portable receiver and URX-M2 tuner module provide a convenient auto channel scanning function that allows for fast, easy, and safe frequency channel changes. These models automatically detect unoccupied channels, allowing operators easily to select the most appropriate channel to use.
