Paramus, N.J. – September 12, 2026 -- Sony Electronics has unveiled the DWT-B40 bodypack transmitter and DWR-R40Q rack-mount receiver, the fourth generation of its DWX Digital Wireless Microphone Series, with availability set for March 2027.
New transmitter adds in-device 32-bit float backup recording
The DWT-B40 incorporates an in-transmitter recording function using Sony's proprietary algorithm, enabling distortion-free backup capture directly on the device in the event of a wireless signal interruption. Recording can be triggered via the REC button or remotely from the receiver through Cross Remote control, with timecode synchronization and microSD card data transfer. Simultaneous transmission and recording is not currently supported in North America.
