DWT-B01 Digital wireless microphone belt-pack transmitter
Overview Sony is proud to introduce a digital wireless microphone system that offers high-quality full-digital operation and enhanced system performance - a perfect match for high-quality ENG/EFP applications. The system, which consists of the DWT-B01 beltpack transmitter and the DWR-S01D dual portable tuner, delivers excellent-quality wireless transmission of 24-bit/48-kHz digital audio. Thanks to the Sony original codec, it realises low-latency, secure, and reliable operation. In addition, the system allows for an increase of up to 60% in the number of simultaneous multi-channel operations compared to conventional analogue systems, which gives users enhanced system flexibility. With its excellent audio quality and operational flexibility, the Sony digital wireless microphone system opens up a whole new world of audio applications. NOTE: This model is available in multiple versions to support the widest possible range of operating frequencies. Please refer to product specifications for more information.
•
Superb Quality Wireless Transmission & Reception The digital wireless microphone system transmits & receives high-quality 24- bit/48-kHz digital audio in a specific frequency bandwidth that meets the Wireless Communication Regulations of each country. Utilising 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.
•
Stable and Secure Transmission & Reception Incorporating the newly developed digital modulator, the digital wireless microphone system allows highly stable wireless transmission that is extremely tolerant to unwanted interference.

In addition, the system transmits & receives digitally modulated and encrypted data to minimize the risk of interception, providing highly secure transmission & reception.
•
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.
