Made with simplicity in mind for DIY cameramen, videographers, vloggers, and journalists working in the field without a crew, the 4th-generation Sony UWP-D27 2-Person Camera-Mount Wireless Omni Lavalier Microphone System is a dependable 2-channel, 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. This compact system is packed with professional features including one-button NFC Automatic Channel-Setting mode and Auto-Gain functions, which handle time-consuming frequency setup and mic-level adjustments for you—so you’re ready to shoot two people talking simultaneously directly to your camera within seconds. It is ideal for documentaries, wedding videos, YouTube content, corporate spots, hands-free interviews, and more.
The UWP-D27 offers digital signal processing for pristine audio and analog UHF transmission with true-diversity reception for reliability, even under difficult shooting conditions. Rugged and lightweight, this system includes two bodypack transmitters, each with an ECM-V1BMP omnidirectional lavalier mic. It also comes with a low-profile camera-mount receiver designed for enhanced mobility with compact camcorders and smaller DSLR/mirrorless cameras. 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 Sony cameras equipped with a digital Multi Interface Shoe. The UWP-D27 is backward-compatible with Sony WL-800, UWP Series, and third-generation UWP-D transmitters.
Press and hold the NFC/Sync button, and the dual receiver scans for the two cleanest RF channels (one for each transmitter). Simply hold the transmitters next to the receiver; it automatically syncs up and you’re good to go!Unlike purely digital systems, the UWP-D27 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 to Prevent Mic Distortion
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 on the transmitters 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.
High-Gain Mode for DSLR and Mirrorless Cameras
The High-Gain mode boosts the output level of the receiver, allowing you to turn down the input gain of your DSLR/mirrorless camera to achieve an even quieter signal.
External Mic Input for Additional Wired Microphone
There is an external mic-input connector on the receiver for plugging in an additional wired microphone. It allows for up to four-channel audio recording when using a stereo microphone.
Built-In 4-Channel Mixer
The receiver features a 4-channel mixer that enables you to control your mic levels (up to four) as well as assign output 1 or/and 2 as needed.
High-Visibility OLED Display for Indoor/Outdoor Use
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.
Channel Memory Function for Fast Switching Between 4 Transmitters
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 up to four mics in corporate presentations or quickly swapping to back-up mics.
DSP Filter Removes Occupancy Sensors Artifacts
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.
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 (True diversity is available only in single-channel mode. In dual-channel mode, the receiver relies on antenna diversity).
The angle of the two antennas can be adjusted to further prevent signal dropouts.
Great for videographers traveling to different cities, the All-Band scanning function scans the entire spectrum of the receiver to give you the two best frequencies at your shooting location. 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. 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.
The UWP-D27 features a robust, all-metal construction well suited for tough operating conditions.
The compact bodypack transmitter is lightweight and comfortable for the talent to wear. A locking, 3.5mm BMP-type microphone input connector ensures that your lav doesn’t detach at a critical moment.
Using the included shoemount adapter, the receiver easily mounts on your camera, while adding minimal weight to your rig. Cables are included to connect to cameras equipped with either a 3.5mm or an XLR audio inputs.
The optional SMAD-P5 digital MI Shoe adapter allows you to integrate the receiver with XDCAM camcorders and select Sony cameras equipped with a digital Multi Interface Shoe.
- This setup provides a direct digital connection, skipping the receiver’s D/A and camera’s A/D converters for superior audio quality and low noise.
- Audio information such as RF level meter, audio-mute status, and low-battery alert for the transmitters is displayed on the camera’s viewfinder.
- This cable-free configuration allows for fast setup in the field.
Two AA batteries (alkaline or NiMH rechargeable type) power the transmitter for up to 8 hours and the receiver for up to 4.5 hours.
A battery count-up timer allows for accurate reading of battery running time to minute accuracy.
The transmitter and receiver can also be powered through their USB ports, allowing them to run for numerous hours on a USB power pack or indefinitely, if you have access to AC.
With the SMAD-P5 Digital MI Shoe adapter, the receiver can get power directly from Sony cameras equipped with an MI Shoe.
Cartridge-type battery cases allow for quick battery replacement on set.
- The RF output level on the transmitter has two settings: the 5mW option allows you to conserve battery life, while the 30mW setting gives you more power to overcome interference, great in busy RF environments.
- Switchable Mic/Line input level, so you can set the correct gain level for your sound source.
- Low-cut filter reduces noise caused by wind or machinery—Off / Low (100 Hz) / Mid (150 Hz) / High (200 Hz).
- The receiver provides a variable output level control of ±12 dB, useful when working with cameras without manual input level control.
- Simple menus make navigation easy. Advanced menus for in-depth control are also available.
- The variable mute button on the transmitter can be programmed for latched or momentary muting. It can also be used as a momentary talk button.
- You can operate up to 16 mics per frequency band in one location.
With this set, you can add the UTX-M40 handheld wireless mic with a cardioid capsule, ideal in situations where you don’t have time to position a lavalier mic or you need to quickly pass the mic between several people.
Adding the UTX-P40 plug-on transmitter with 48V phantom power allows you to connect any handheld microphone of your choice for man-on-the-street-style interviews or a shotgun mic for wireless booming.
For clearer speech in noisy environments, you can substitute the included lav mic with an ECM-322BMP headset mic.
- The transmitter can be used with WL-800 Series, UWP Series, or third-generation and fourth-generation UWP-D Series receivers.
- The transmitter can be used with WL-800 Series, UWP Series, or third-generation and fourth-generation UWP-D Series transmitters.
