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.
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 |

| | | |
CE model | CE62 | 798 MHz to 822 MHz | 189 (in 125-kHz steps) |
| | | /960 (in 25-kHz steps) |
| CE67 838 MHz to 862 MHz | 190 (in 125-kHz steps) |
| | | /960 (in 25-kHz steps) |
| | | |
AU model | AU66 | 792 MHz to 806 MHz | 102 (in 125-kHz steps) |
| | | |
CN model | CN | 758 MHz to 782 MHz | 188 (in 125-kHz steps) |
| | | |

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.
