The 470 to 542 MHz version of the Sony UWP-D16 Integrated Digital Plug-on & Lavalier Combo Wireless Microphone System features an all-metal chassis, an easy to read LCD display, a wide switching RF bandwidth, USB power and charging options, automatic channel scanning, infrared synchronization between transmitter and receiver, Mic/Line switchable inputs on both the bodypack and plug-on transmitter, +48V phantom power from the plug-on transmitter, a true diversity receiver, PLL-synthesized tuning, an output gain control on the receiver for optimizing the audio input level to a camera/camcorder, 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. The system is referred to as integrated digital because the transmitters and receivers utilize DSP for digital companding and expanding of the transmission signal. Performing the companding and expanding processes in the digital domain improves the accuracy and transient response of the received audio. The camera-mountable receiver features true-diversity technology which stabilizes reception and minimizes RF interference by using dual antenna input/reception circuits and selecting the strongest incoming signal. The angle of the antennas is also adjustable to improve reception when the receiver is mounted on top of a camera or camcorder. The system utilizes UHF Phase Locked Loop (PLL) synthesis to lock the phase of the transmission frequency between transmitter and receiver. The receiver can automatically search for an available transmission frequency and link the desired frequency to the transmitter via infrared connection. A stereo mini-jack output with monitor volume control is featured and both stereo mini and stereo XLR cables are provided for optimizing the audio input into a camera or camcorder.
