The Sony DWT-B30 is a is a third-generation DWX Digital Series wireless bodypack transmitter compatible with the DWR-R03D rackmount and DWR-S03 slot-in receivers as well as all previous DWX Digital Series receivers.

The compact transmitter features tough magnesium housing and a Sony 4-pin Hirose input connector, allowing you to plug in a lavalier or headset mic of your choice for hands-free performances, interviews, and presentations. The unit delivers professional-quality, 24-bit digital audio and is ideal for large-scale, multichannel applications, including broadcast and film production.

The DWT-B30 operates in a single, ultrawide 140 MHz UHF bandwidth and offers selectable 2/10/25mW RF output power, extremely low latency, and a transmission range up to 300'. Four codec modes provide flexible options allowing you to prioritize sound quality, latency, or compatibility with previous generations. AES 256-bit encryption is on board for secure transmission. Two AA batteries power the unit for up to 6.5 hours, while the micro-USB port can also supply power while in operation.

Transmitter functions, including gain control, RF frequency selection, RF power output, low-cut filter, and low-power sleep mode, can all be controlled remotely from the portable DWR-S03D receiver or the rackmount DWR-R03D receiver. The DWR-R03D features networking capabilities, allowing you to control multiple transmitters via a computer running Sony's Wireless Studio control software, for high-channel count applications.

Additional compatible receivers include the DWR-R02DN, DWR-S02DN, DWR-S02D, DWR-R02D, DWR-R01D, and the DWR-S01D.
