The Sony UTX-M40 is a wireless handheld microphone transmitter compatible with the URX-P40 camera-mount receiver. The rugged, all-metal design is comfortable for performers and presenters to hold and is well suited for tough operating conditions. The transmitter offers a 72 MHz bandwidth with 2772 selectable UHF frequencies. It provides up to 8 hours of operation on two AA batteries, with an adjustable 5/30mW RF power output and a transmission range up to 330'.


The UTX-M40 features a dynamic microphone capsule with a cardioid pickup pattern that focuses audio capture on the presenter in front of the mic while reducing unwanted background noise. The transmitter uses an interchangeable mic capsule design compatible with over 40 different capsules from various manufacturers.
The UTX-M40 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.

The handheld mic features a dynamic mic capsule with a directional cardioid polar pattern that helps to reject unwanted background sound, making it ideal in noisy environments such as trade-show floors or busy public areas.

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-B40 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 8 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
  • Low-cut filter reduces plosives and filters out noise caused by wind and 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 Power/Mute button 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.

What size mic head does this have. When I tap accessories for this mic the phone windscreens come in five different sizes so don't know which one to get
Asked by: Paul
The microphone head on the Sony UTX-M40 Wireless Handheld Cardioid Microphone Transmitter has a diameter of 1.8" (45.7mm) and height of 3.1" (78.7mm). A windscreen for 1-5/8" (which is 1.625" as a decimal or 41.3mm) diameter should work best. The foam stretches and it will fit securely around the widest part of the microphone.
