The Sony UWP-D11 638 to 698 MHz Integrated Digital Wireless Bodypack Lavalier Microphone System features all-metal construction, easy to read LCD displays, a wide switching RF bandwidth, USB power and charging, automatic channel scanning, infrared synchronization between transmitter and receiver, Mic/Line switchable input on the bodypack transmitter, a true diversity receiver, PLL-synthesized tuning, a headphone output on the receiver, output gain controls on the receiver for optimizing the input level into a camera, and digital companding circuitry. The package is suitable for a wide range of wireless applications such as ENG, documentary work, talk shows, conferences, and more.

Compact, Leightweight and Robust Design

All components of the UWPD Series – bodypack transmitter, handheld microphone, plug-on transmitter, portable receiver, and tuner unit – utilise 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.

PLL Synthesised System

The UWP Series employs a UHF PLL (Phase Locked Loop) frequency synthesised system, which provides a stable carrier signal that avoids 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 reception interruptions (signal dropout), but UWP-D series tuners reduce this to a minimum. By 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.

Tone Squelch Cicuitry

To avoid picking up carrier signals transmitted from other systems, the transmitter transmits a 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 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.

Simultaneous Multi-channel Operation

Optimum combinations of practically tested, interference-free frequencies are stored in the tuner. By using the pre-programmed frequency groups, users can easily choose interference-free frequencies for the transmitters and tuners, simplifying the task of system setup.
