Sony Electronics to Launch DWM-30 Digital Wireless Microphone with Enhanced Transmission Performance and Sound Quality



WM-30 Digital-Wireless Microphone with CU-C31 capsule


Sony Electronics Inc. is expanding its DWX Series of true digital wireless technology with the DWM-30 professional handheld microphone. The new model is compatible with the entire DWX family and can utilize three different Sony mic capsules with different pick-up patterns, and also accepts third-party mic capsules.

The DWM-30 digital wireless microphone transmitter is the successor to DWX Series model DWM-02N, an established choice for a range of professional audio recording environments from broadcast stations to live music performances. The new model combines a user-friendly design, reduced weight, and an approximately six-hour battery life with support for the latest codec modes. It is compatible with current DWX series models and operates within the frequency guidelines adopted as a result of the FCC spectrum reallocation. This model features a wideband operation (up to 148MHz) and allows tuning to frequencies as mandated by the FCC spectrum guidelines UHF-TV Ch 14-36 (470.125-607.875MHz) and 38 UHF-TV (614.125-615.875MHz).

DWM-30 Key Features

  • Improved Transmission Performance for Stable Operation: The DWM-30 uses an electromagnetic field simulation in its design to enhance transmission performance and enable more stable operation.
  • Faithful Sound Reproduction: The DWM-30s revised electrical circuits and mechanical structure contribute to improved sound quality. Support for CODEC MODE 4 balances high-quality transmission and low latency, delivering sound that is more faithful to the original.
  • User-Friendly Design, Reduced Weight, and Approximately Six-Hour Battery Life: An optimized mechanical structure creates an easy-to-grip design and an approximately 10% weight reduction compared to the previous model (DWM-02N). The DWM-30s power-efficient design extends battery life by about one hour over the DWM-02N, achieving approximately six hours of operation (when using alkaline batteries).
  • Support for Latest Codecs and Multiple Channels: The DWM-30 supports CODEC MODE 2 to achieve a low latency of 1.2m/sec and adds support for CODEC MODE 4 to balance high-quality transmission and low latency. The DWM-30 also supports a wide band of up to 148MHz in the TV white space band with a 375kHz channel plan, allowing for up to 16 channels per TV band for multi-channel simultaneous connections.
  • High Gain Mode: The DWM-30 features a High Gain Mode that allows for three-stage amplification (+6/+12/+18dB) when normal settings are insufficient. This mode helps maintain audio levels even in situations where the microphone is held away from the mouth, for example during interviews or vocal performances.
