Sony Dual Channel UWP-D Kit. 1 x URX-P41D/K33 & 2 x UTX-B40/K33 transmitterMade with simplicity in mind for DIY cameramen, videographers, vloggers, and journalists working in the field without a crew, the 4th generation Sony UWP D27 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

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 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.

Professional Features to Speed Up Your Workflow

NFC Automatic Channel-Setting Mode
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.

Reliable Reception with True Diversity and All-Band Scan

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.

High-Quality Sound with Digital Audio Processing

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.

A Compact Build, Ready for the Camera

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.

Direct Digital Audio via SMAD-P5 MI Shoe Adapter

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.

Multiple Powering Options

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.

Headphone Monitoring for Location Sound

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

Other Features

  • 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.

Configure Your System to Do More

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.

Compatibility with Other Sony Wireless Systems

  • 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.

Perfect to fix your Epson Ink Pad Counter Issue
Exactly what I needed! My Epson ET-4700 started displaying an 'E-11' error on the display so I learned I would have to replace the ink pad. The package came with 4 ink-pad receptacles, four baggies for discarding the old ones, plastic gloves and even a miniature screwdriver to get the backing off of the printer. The hardware part was super simple to remove the old and install the new. Hit a bit of a snag with the included software(which was a link to a website)which Windows Defender kept blocking no matter what I tried, but a quick email to support they answered right away. Sent me to a link for better software and I was able to successfully get my printer working again. A+++ transaction and service. Thanks again!

Good product-May need to troubleshoot
I am giving this product five stars even though I had issues resetting my printer because it was not product fault. The maintenance box was easy to install. Based on other reviews, I was prepared for the wic reset site that looked suspicious. I will say it is legit. I purchased a reset key which I later found out that I did not need. Read further and I will explain. After I downloaded the WIC software, I spent over 2 hours troubleshooting yrying to reset my printer. I am writing this hoping that it might help others. In the end, the problem was my Wi-Fi was not recognizing the printer. When I was trying to reset it. I ended up connecting my printer via USB cable and I was immediately able to reset my printer and start printing again. I am going to list the troubleshooting steps I took, but you might want to try that first. In addition, before purchasing a reset key, they do offer a trial key. If you have never used a trial on that printer. I suggest doing this first because in the end I used the trial rather than the key that I had purchased. Here are a few additional troubleshooting steps you could try: 1. Ensure Correct Reset Key: Double-check that the reset key you purchased is for the correct model of your printer. If it's specific to another model or region, it may not work correctly. 2. Reinstall WIC Software: Uninstall and reinstall the WIC software to make sure it's functioning properly. Sometimes a corrupted installation can cause errors. 3. Run the Software as Administrator: Make sure you are running the WIC software as an administrator. Right-click on the WIC Reset tool icon and choose "Run as Administrator." 4. Disable Firewall/Antivirus Temporarily: Your firewall or antivirus software may be interfering with the connection. Temporarily disable them and try again to see if that helps. Make sure to turn it back on when finished. 5. Try a Different USB Port: If you are connecting via USB, try switching to another port. Alternatively, if you're using Wi-Fi, you might want to try a USB connection to see if that helps the software communicate with the printer. This is what worked for me. 6. Use a Different Computer: If possible, try using the reset software and key on a different computer. Sometimes system-specific issues can interfere with communication between the software and the printer. 7. Check for Firmware Updates: Ensure that your printer's firmware is up to date. If it's outdated, it might cause incompatibility with the reset tool. Be cautious, as some updates can prevent third-party reset tools from working. If none of the above works, it might be worth contacting the vendor of the reset key. They may have specific guidance or offer a replacement key if the one you purchased is faulty. Last resort would probably be to call Epson.

Perfect for my Epson 2720!
When my Epson 2720 printer pooped out on me and said my ink waste box was full, I was so sad. After watching a billion YouTube videos, I learned there are a ton of people selling new ink boxes and I had no clue which one to pick. I am the most electronically illiterate person on the planet so I just knew it wouldn't be easy for me to fix... wrong! This kit came with the new ink waste box, tools to change it out, a bag to throw the ink filled box into, instructions, and an extra pad for next time. After removing the old box, the new one slid in perfectly. Resetting the wic code was extremely easy as well! The instructions show step by step diagrams on what to do. It was a fast and simple process. It all worked out too well for me (normally it's a domino effect of chaos when I repair something) so the first print to see if it all worked was a nail biter. It printed beautifully! If you have a 2720 that needs repaired, this is the product for you!
