SONY Wireless XLR Plug-on Transmitter (14)

SONY Wireless XLR Plug-on Transmitter (14) is a compact UWP-D plug-on transmitter made for turning compatible XLR microphones into wireless sources. From the supplied source, the Sony UTX-P40 uses an XLR-3-11C female input connector, supports +48V power, and operates on the UC14 frequency range from 470.125 to 541.875 MHz.

This is useful when the crew wants the handling of a familiar XLR microphone without keeping it tied to the camera by cable. A reporter mic, handheld interview mic, or compatible XLR microphone can stay mobile while the audio is sent wirelessly back to the receiver.

Why It Helps

The UTX-P40 is helpful when the microphone choice matters as much as the wireless link. Crews can keep using a preferred handheld or XLR microphone while avoiding a long cable run back to camera, mixer, or receiver position.

The wide attenuator range gives the operator room to manage different source levels before the signal hits the wireless path. That is useful when moving between quieter speech, louder presenters, or microphones with different output behavior.

Powering is flexible too. AA batteries keep the transmitter portable, while USB-C power is useful when the unit is used in a longer fixed setup or powered production environment.
