Sony DWX Gen 4 Wireless System Detailed - 32-Bit Float Recording, 1.1ms Latency, and a 30% Price Cut

Key Points:

• Sony’s fourth-generation DWX digital wireless microphone system introduces 32-bit float recording inside the DWT-B40 bodypack transmitter and a new four-channel DWR-R40Q rack-mount receiver, while maintaining backward compatibility with DWX systems from 2012 onward.
• The DWT-B40 records high-dynamic-range 32-bit float audio locally on microSD cards (up to 2TB), serving as a backup and enabling isolated post-production, though this recording is not transmitted wirelessly due to bandwidth limitations.
• Latency has been reduced to approximately 1.1ms for both analog and digital outputs, and a new Codec Mode 6 aimed at improving audio quality is planned for release in early 2027.
• The system supports extended tuning ranges and up to 82 channels in studio setups, with enhanced remote control range (up to 50m) via a dedicated 2.4GHz antenna, and offers flexible power options including AA batteries, lithium-ion, and USB power.
• Pricing is set at about €1,290 for the DWT-B40 transmitter and €6,490 for the four-channel receiver, with availability expected around February or March 2027; however, U.S. users face restrictions on simultaneous recording and transmission due to a patent, which may be lifted in a few years.
