The Sony UWP-D21 is a dependable camera-mount wireless lavalier microphone system that delivers uncompromising audio quality while still being easy to use and fast to set up with no menu diving. It is made with simplicity in mind for DIY cameramen, videographers, vloggers, and journalists working in the field without a crew. The system is packed with professional features, including NFC Sync and Auto-Gain functions, which handle time-consuming frequency setup and mic-level adjustments for you, so you're ready to shoot within seconds. Sony shooters can take advantage of the SMAD-P5 digital MI Shoe adapter (available separately), which provides a direct, clean digital audio connection to select cameras equipped with a digital Multi Interface Shoe. With the UWP-D21, you can focus on the other critical elements competing for your attention during a shoot and confidently record crisp, clear speech, or dialog for projects ranging from documentaries to wedding videos, YouTube content, corporate spots, and hands-free interviews.

Press and hold the NFC/Sync button, and the receiver scans for the cleanest RF channel. Simply hold the transmitter next to the receiver; it automatically syncs up and you’re good to go. Unlike purely digital systems, the UWP-D21 allows you to send a single mic to multiple cameras for broadcast applications. Fast NFC communication makes setup for multiple receivers a breeze

Auto-Gain mode saves you the time and aggravation of setting and managing the input level on the transmitter. It uses a limiter to help prevent distortion, great when the loudness of the presenter’s voice is unknown. The +15 dB Gain Volume-Boost mode boosts the mic gain by 15 dB to compensate for situations when the mic is not close enough to the presenter’s mouth and the audio level is insufficient. Manual input-level setting is also available.

Both transmitter and receiver feature an easy-to-read OLED display. The quick response of the display lets you see the operating conditions clearly and accurately in real time, even in bright sunlight.

The channel memory function lets you quickly switch between the groom's lav mic and the wedding guest's interview mic with the press of a button. It also allows for a fast change between mics in corporate presentations or quickly swapping to a back-up mic.

To achieve stable audio, the UWP-D receiver employs true-diversity technology with two antennas and two independent receiver sections within the unit. Both RF signals are compared and the stronger signal is automatically selected for output—reducing dropouts to a minimum. The angle of the two antennas can also be adjusted, which helps to further prevent signal dropouts. The system offers a 72 MHz bandwidth with 2772 UHF frequencies.

Unlike traditional analog wireless systems, The UWP-D supplements its proven analog UHF transmission technology with a proprietary digital audio processing. Two levels of DSP filtering help remove the artifacts caused by occupancy sensors used in modern "green" buildings to turn off lights when people leave a room. Transient sounds and consonants are reproduced with greater accuracy, resulting in clear, natural sound that’s intelligible and nuanced. The ECM-V1BMP lavalier mic is optimized for capturing clear and intelligible speech. This omnidirectional mic picks up sound from every direction, allowing for a variety of placement options and freedom of movement.
