Since their first introduction in 1974, Sony has been continuously developing a rich range of wireless
microphone systems to offer superb audio performance, highly stable transmission, and flexible
simultaneous multi-channel operation. Nowadays, it can be clearly seen that the industry is migrating
from standard definition (SD) to high definition (HD) for video production, as well as from analog to
digital for sound production. This trend naturally boosts the need for higher-quality digital technology in
wireless microphone systems.
With the introduction of a fully digital wireless microphone system, Sony has made a breakthrough in the
history of wireless microphone technology. Comprised of the DWT-B01 bodypack transmitter, DWR-S01D
slot-in type two-channel receiver, DWA-01D adaptor, and DTW-P01, newly introduced plug-on transmitter,
the system provides excellent-quality digital wireless audio transmission, large-scale, multi-channel
operation, and enhanced system flexibility – a perfect match for high-quality ENG/EFP applications.*

DWT-P01 is a plug-on transmitter that allows an existing wired microphone to be integrated into the digital
wireless microphone system. Its compact and lightweight metal body provides high durability and good
balance with compatible microphones, especially when combined with F-112 Sony Dynamic Microphone -
ideal for conducting smooth interviews and sound gathering in high-quality ENG applications.
Transmission of excellent-quality 24-bit/48-kHz sampling digital audio signals is realized on the DWT-B01/
DTW-P01 transmitter. The audio codec used in the system was developed specifically for wireless audio
transmission, enabling the low-latency, secure, and reliable operation that is mandatory for quality-critical
applications. In addition, the system allows for an increase of up to 50%*

in the number of simultaneous
digital wireless systems in use compared to conventional analog wireless systems, which gives users
enhanced system flexibility. Furthermore, the system offers a metadata-handling capability that provides
highly innovative full-wireless remote operations between the transmitter and receiver, dramatically
improving operational efficiency.
With its excellent audio quality, system flexibility, and operational efficiency, the Sony digital wireless
microphone system opens up a whole new world of professional audio applications.
