SONY Wireless XLR Plug-on Transmitter (90)

SONY Wireless XLR Plug-on Transmitter (90) 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 UC90 frequency range from 941.625 to 959.625 MHz.

This is useful when a crew wants to keep a preferred handheld or XLR microphone in service without running a cable back to the receiver position. The mic stays familiar in the hand, while the UTX-P40 handles the wireless link for ENG, interviews, documentaries, event work, and field production.

Why It Helps

The UTX-P40 is handy when the microphone choice matters but the cable run gets in the way. A reporter mic, handheld interview mic, or compatible XLR microphone can be used wirelessly while the receiver stays with the camera or audio operator.

The 0 dB to 48 dB attenuator range gives the operator room to handle different source levels before the signal reaches the wireless chain. That is useful when moving between quiet speech, louder presenters, or microphones with different output behavior.

Powering is flexible as well. AA batteries keep the transmitter fully portable, while USB-C power is useful for longer fixed setups or powered production environments. The OLED display keeps status checks quick, especially when the crew is moving fast.
