Product Description
The Sony UWP Series Bodypack Transmitter with Omni-Directional Lavalier Mic for the UWP-C1 Wireless System comes supplied with an omni-directional lavalier microphone. This bodypack transmitter is ideally suited for news gathering, interviews, talk shows and conferences. Key to achieving stable transmission & reception is the use of a stable carrier signal to avoid interference with other frequency channels & to allow the selection of a preferred channel from multiple frequencies. The UWP series achieves this by using a UHF Phase Locked Loop frequency synthesized system, which provides the use of accurate carrier signal frequencies. This system is used in both the transmitter & tuners, so that a stable carrier is gene rated at the transmitter & accurately tuned in at the tuner. This PLL-controlled system provides highly stable, user-selectable frequencies in increments of 125 kHz. When operating a wireless microphone system, it is essential that the tuner not pick up carrier signals transmitted from other systems. In order to avoid this, the UWP series transmitters transmit a 32 kHz pilot-tone signal along with the audio signal. The squelch circuit of the UWP series tuners recognizes this tone signal and output the audio signal only when this tone signal is received.
