The Sony UWP-D11 Digital Wireless Bodypack Lavalier Microphone System is a professional-grade wireless audio solution engineered for ENG, documentary, talk shows, and conference work. Built around DSP-based digital companding circuitry, it delivers superior audio transient response across a wide 66 MHz UHF switching bandwidth (566–608 MHz and 614–638 MHz), giving broadcasters and filmmakers clean, interference-free sound in demanding environments.
The system pairs the UTX-B03 bodypack transmitter and the URX-P03 true diversity receiver with the ECM-V1BMP omnidirectional electret condenser lavalier, offering selectable 5 mW or 30 mW output power, USB Micro-B charging for both units, infrared synchronization, and automatic channel scanning — all housed in rugged all-metal construction with easy-to-read LCD displays.
Key features
- DSP Digital Companding: Analog-to-digital and digital-to-analog converter stages compand and expand the signal digitally, dramatically improving audio accuracy and transient response compared to traditional analog companding.
- True Diversity Reception: The URX-P03 uses dual antenna circuits to continuously select the strongest incoming signal, minimizing RF dropouts and interference — ideal for run-and-gun and multi-camera shoots.
- Selectable Transmission Power: Switch between 5 mW for simultaneous multi-channel operation or 30 mW for extended long-distance transmission, giving you flexibility on any production set.
- USB Power & Ni-MH Charging: Both transmitter and receiver can be powered or charged via USB Micro-B, while the receiver also recharges Ni-MH batteries in-situ — up to 8 hrs on the transmitter and 6 hrs on the receiver with AA batteries.
- Automatic Channel Scanning & IR Sync: The receiver scans for a clear UHF channel and links it to the transmitter instantly via infrared, eliminating manual frequency coordination and saving critical setup time on location.
- Camera-Ready Design: A shoe-mount adapter, adjustable antennas, output gain controls, headphone monitor output, and both 3.5mm and XLR cables make the UWP-D11 plug-and-play compatible with DSLRs, mirrorless cameras, and professional camcorders.

Frequently asked questions
How does the Sony UWP-D11 reduce audio noise compared to analog wireless systems?
The UWP-D11 uses DSP-based digital companding circuitry — the transmitter digitally compresses the audio signal before transmission and the receiver digitally expands it on receipt. Processing in the digital domain improves accuracy and transient response, resulting in noticeably cleaner audio with less noise than traditional analog companding systems.
Can I use the Sony UWP-D11 receiver directly on a DSLR or mirrorless camera?
Yes. The URX-P03 receiver includes a shoe-mount adapter for easy attachment to most DSLRs and mirrorless cameras. It also features adjustable antennas for optimized reception when top-mounted, a 3.5mm stereo mini-jack output, output gain controls for matching camera input levels, and a headphone monitor output for cameras without a built-in monitor output.
What is the battery life of the UWP-D11 and can it be powered by USB?
The UTX-B03 transmitter runs up to 8 hours on two AA alkaline batteries, while the URX-P03 receiver runs up to 6 hours on two AA batteries. Both units support USB Micro-B for continuous USB power. The receiver can also recharge Ni-MH rechargeable batteries in the battery cartridge via the same USB Micro-B connection.
