The Sony URX-P40 Wireless Receiver UC90 941-960 MHzis a camera-mount wireless receiver 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 receiver is packed with professional features including NFC Sync and Channel Memory functions, which handle time-consuming setup and adjustments for you, so you're ready to shoot within seconds.

The URX-P40 offers digital signal processing for pristine audio and analog UHF transmission with true-diversity reception for reliability, even under difficult shooting conditions. This low-profile, camera-mount receiver is 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 cameras equipped with a digital Multi Interface Shoe.

The URX-P40 is backward-compatible with Sony WL-800 and UWP Series systems.

For UWP-D Wireless Systems    True-Diversity Camera-Mount Receiver    654 Auto-Scan Frequencies with NFC    Professional Features for Fast Workflow    Daylight-Readable OLED Display    Headphone Output for Monitor Mode    6-Hour AA Batteries + USB Power    Up to 14 Mics on Set / 330' Range

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 an 18 MHz bandwidth with 654 UHF frequencies.

NFC Automatic Channel-Setting Mode

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 URX-P40 allows you to send a single mic to multiple cameras for broadcast applications. Fast NFC communication makes setup for multiple receivers a breeze.

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

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.

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 URX-P40 features a robust, all-metal construction well suited for tough operating conditions.

Using the included shoe mount adapter, the receiver easily mounts on your camera, while adding minimal weight to your rig. Cables are included to connect it to cameras equipped with either a 3.5mm or an XLR audio input.

The 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.
• Compatible models include the a7R IV mirrorless camera, the PXW-Z280 and PXW-Z190 XDCAM camcorders, and more.

Two AA batteries (alkaline or NiMH rechargeable type) power the receiver for up to 6 hours.

A battery count-up timer allows for accurate reading of battery running time to minute accuracy.

The receiver can also be powered through its USB port, allowing it 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 case allows for quick battery replacement on set.

If your camera doesn’t have a headphone jack, Phone mode lets you monitor your sound via the receiver’s headphone output while recording.

When the receiver is used as a personal monitoring device by a director or crew on set, Monitor mode lets you adjust the headphone volume on the fly with the +/- buttons.

• 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.
• You can operate up to 16 mics in one location.

The URX-P40 can be used with a UWP Series or WL-800 Series transmitter.
