Sony DW Digital Radio Mic kits











With its excellent audio quality and operational flexibility, the Sony digital wireless microphone system opens up a whole new world of audio applications.

The digital wireless microphone system transmits (Sony DWT-B01) & receives (Sony DWR-S01D) high-quality 24- bit/48-kHz digital audio in a specific frequency bandwidth that meets the Wireless Communication Regulations of each country. Utilizing the Sony original codec based on Sony’s years of experience in engineering audio products, the system delivers a wide dynamic range of more than 106 dB, a wide frequency response of 20 Hz to 20 kHz, and an excellent transient response.

Simultaneous Multi-channel Operation.

The digital wireless microphone system allows for large-scale multi-channel operations. Thanks to the newly developed digital modulator, the system realises an intermodulation-free, equally spaced channel allocation. The digital wireless transmission technology used in this system enables a significant increase in the number of simultaneous operations in comparison with current analogue wireless systems. For example, up to16 channels of simultaneous operation is possible in an 8-MHz operating band.

This is a popular option for camera operators who are asked to look after sound recording form multiple sources and require a ‘slot in’ solution.
