Used Sony UTX-B03 Integrated Digital Wireless Bodypack Transmitter with Omni Lavalier Microphone, UHF Channels 42/51: 638 to 698 MHz

The Sony UTX-B03 Integrated Digital Wireless Bodypack Transmitter (UHF Channels 42/51: 638 to 698 MHz) 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.

Digital Companding
Utilizes analog-to-digital and digital-to-analog converter stages so that the transmission signal can be digitally companded by the transmitter and digitally expanded by the receiver for improved audio transient response.

Automatic Channel Scanning
Scans for available transmission channels and then syncs the transmitter to the receiver via infrared.

Frequency Coverage
Provides up to 60 MHz of transmission bandwidth.

UWP Series / WL-800 Series Compatibility
Enables cross-compatibility between the UWP-D transmitter with a UWP Series or WL-800 Series receiver.

USB Power Options
Supports USB powering and USB charging of internal Ni-MH rechargeable batteries placed in the battery cartridge.

UHF Phase Locked Loop (PLL) Synthesized Frequencies
Provides stable transmission and reception by generating a transmission frequency and locking the phase of the transmission signal to the incoming signal of the receiver.

Tone Squelch Circuitry
Transmits a pilot-tone signal with the audio signal and only outputs the audio signal if the pilot tone is present to reduce RF interference from other sources.

Mic and Line Input Switch
Enables switching between microphone- and line-level input sources.

Simultaneous Multi-Channel Operation
Stores the most stable interference-free transmission frequencies to internal memory for rapid setup and switching between frequency groups.

Selectable RF Output
The transmitter allows selection between 5mW output power and 30mW output. 5mW is suitable for indoor, simultaneous multi-channel operation while 30mW is intended for outdoor, long-range use.

Visual Display
Features a comprehensive LED display providing channel and frequency information, battery life, total usage time and more.

All-Metal Construction
Features metal construction for durability.
