The Sony UTX-M40 Wireless Handheld Cardioid Microphone Transmitter (638-694MHz) 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 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.
