Small, light and resistant

At just 53mm x 60mm x 17mm (exc. Antenna), the DWT-B03R is incredibly small and lightweight. It also features a tough magnesium body that’s resistant to rain, spray and sweat.

Wide-band, more channels per band

The DWT-B03R is ideal for use in large-scale multichannel productions. Its 144MHz bandwidth per pack means the bandwidth is almost doubled over the previous versions. DWX3 supports up to 21 simultaneous channels per 8MHz TV band.

Extreme stability and low-latency

Sony’s advanced digital audio processing, encryption and RF transmission technologies assure secure, stable transmission and reception of very high quality audio with low latency.

Control 82 transmitters remotely

The Sony DWT-B03R is compatible with Sony Wireless Studio control software for PC (Ver 5.0 or later), allowing flexible remote operation. Remote control of up to 82 transmitters is possible using the Cross Remote™ function combined with the RMU-01 remote control unit (available separately).

New battery power and OLED display

The DWT-B03R transmitter uses Sony’s NP-BX1 Li-Ion battery and charges via the BC-DWX1 Battery Charger, which is equipped with PoE (power over Ethernet) capabilities. More than 7hours. Easily available across the world – low cost. Navigating the onboard menu system and controlling parameters on the unit is made easier by the incorporation of a high-resolution OLED display with superior clarity and less overall power consumption. The battery provides up to 7.5 hours of use.
