Sony UWP-D11 Description
The Sony UWP-D11 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.
The system is referred to as integrated digital because the transmitter and receiver 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.
