Sony UTX-P40 Overview

The Sony UTX-P40 is a wireless plug-on transmitter compatible with the URX-P40 camera-mount receiver. Compact and lightweight, with a robust, all-metal construction, this plug-on is well suited for tough operating conditions. It provides up to 6 hours of operation on two AA batteries, with a selectable 5/40mW RF power output and a transmission range up to 330'.

The UTX-P40 can be attached to a handheld microphone of your choice for man-on-the-street interviews, or to a shotgun mic for wireless booming (both types of mics are available separately). The plug-on provides 48V phantom power, giving you the option to use a condenser microphone. The transmitter offers a 72 MHz bandwidth with 2772 selectable UHF frequencies.

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

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.
Automatic NFC Sync Mode
Press and hold the NFC/Sync button on the receiver and it 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 UTX-P40 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 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-Visibility OLED Display for Indoor/Outdoor Use
The unit features 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.
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.
Multiple Powering Options
Two AA batteries (alkaline or NiMH rechargeable type) power the transmitter for up to 6 hours.

The unit 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.

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

Other Features
  • 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).
  • 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 in one location.
Compatibility with Other Sony Wireless Systems
The UWP-D transmitter can be used with a UWP Series or WL-800 Series receiver. A UWP Series or WL-800 Series transmitter can be used with a UWP-D receiver.

Sony UTX-P40 Reviews

Nice transmitter

Bought it to use with handheld and SDC mics with my existing Sony UDP system. Used it once already and was impressed by the battery life and quality of it.

Rock Solid Sony Audio

Built like a tank! Weighty metal construction, distinct buttons, easy to read OLED screen, syncs up super quick with Sony URX-P03D receiver and connects via MiShoe to our Sony PXW-z150 cameras: sans wires is definitely a favorite part of this system. Lots of helpful settings in the mic. Menu is relatively easy to navigate. Mute button simple toggle on/off. We pair this transmitter up with Sennheiser MD46 for postgame interviews, etc. Crystal clear sound, good noise rejection, nice that levels can be adjusted inside the transmitter, including phantom power if necessary. Also works great for plugging into house mix AUX to send audio into camera via Sony URX-P03D receiver.

It works great on USB without the batteries. Make sure you keep the USB Power Source a small distance away from the UTX-P40. I unplug the USB when not on use.

I own a Sony UWP D21 kit purchased in Europe labelled CE21 470-542MhZ and would like to add this plug on transmitter which is labelled UC14 for the same frequencies band. Would it work ? Or there are some specificities to each market making them incompatible in spite of having the same usable band ? Thanks
Asked by: Florian
The transmitter will work as long as both components operate within the same frequency band. The difference is where the warranty is valid. UC14 carries a US warranty while CE21 carries a European warranty.
