SONY DWX Ultra Wideband Plug-on Transmitter

SONY DWX Ultra Wideband Plug-on Transmitter is a high-performance digital wireless plug-on transmitter built for live sound, studio television production, ENG, and EFP workflows. From the supplied source, it is part of Sony’s third-generation DWX digital wireless microphone system and uses an XLR-3-11C female input connector for microphone or line-level operation.

This is the kind of transmitter that makes sense when a wired handheld or shotgun microphone needs to become part of a secure digital wireless system. With wideband operation, selectable RF output power, four codec modes, remote control support, and USB power capability, it gives production crews a practical plug-on option for demanding field and broadcast audio work.

Why It Helps

This plug-on transmitter is useful when production audio needs the flexibility of wireless operation without changing the microphone itself. For ENG interviews, boom work, live event coverage, theater, concerts, or studio TV, the XLR input lets crews adapt compatible microphones into the Sony DWX digital wireless chain.

The wideband tuning and selectable RF power are helpful in crowded RF environments. Engineers can choose 2 mW, 10 mW, or 25 mW depending on whether the priority is dense multi-channel planning, stable range, or long-distance operation.

The four codec modes give the transmitter more room to match the job. One mode supports first-generation DWX-series devices, another prioritizes short latency with stable transmission and high audio quality, another adds processing against pulse interference, and another keeps audio quality high while maintaining stability and low delay.

System Characteristics

• 24-bit digital wireless audio for high-quality transmission and reception
• AES 256-bit encryption for secure digital transmission
• Cross Remote control for input attenuation, RF frequency, RF power, low-cut filter, and sleep mode
• High-density multi-channel operation with 375 kHz spacing
• Low audio latency down to 0.7 ms depending on codec mode
• Low-noise head amplifier with -128 dBu noise floor
• User settings memory for storing and loading transmitter settings
• OLED display for quick operational status checks
