The 638 to 698 MHz version of the Sony UTX-B03 Integrated Digital Wireless Bodypack Transmitter with Lavalier Microphone features an all-metal chassis, an easy to read LCD display, a wide switching RF bandwidth, USB power and charging options, infrared synchronization between transmitter and receiver, a Mic/Line switchable input, and digital companding circuitry to improve the transient response of received audio. The package is suitable for a wide range of wireless applications such as ENG (electronic news gathering), documentary work, talk shows, conferences, and more.
The system utilizes UHF Phase Locked Loop (PLL) synthesis to lock the phase of the transmission frequency between transmitter and receiver. The transmitter and receiver can be linked to an available transmission frequency via infrared. An LCD display provides channel and frequency information, battery life, RF level, audio status and accumulated operating time.
For power, the transmitter operates on two AA batteries for up to 8 hours, or on 5 VDC of USB power over a USB micro B cable. The USB connection can also be used to recharge Ni-MH rechargeable batteries within the battery cartridge.
The unit features a mic- and line-level switch for standard wired microphone- or line-level sources with adjustable attenuation. Selectable transmission output power provides a choice between 5mW output, which is suitable for simultaneous multi-channel operation, or 30mW output for long distance transmission.
The transmitter is referred to as integrated digital because it utilizes DSP to compand the transmission signal. Performing the companding and expanding processes in the digital domain improves the accuracy and transient response of the received audio.
The unit comes with an omnidirectional electret condenser lavalier microphone, a windscreen for the microphone, a microphone holder clip, and a belt clip.
