SONY Wireless XLR Plug-on Transmitter (25)

SONY Wireless XLR Plug-on Transmitter (25) is a compact UWP-D plug-on transmitter made for adding wireless operation to compatible XLR microphones. From the supplied source, the Sony UTX-P40 uses an XLR-3-11C female input connector, supports +48V power, and operates on the UC25 frequency range from 536.125 to 607.875 MHz.

This is the kind of transmitter that is useful when a crew wants to keep using a favorite handheld or XLR microphone without running a cable back to the camera or receiver position. It keeps the mic familiar in the hand, but gives the operator a wireless path for ENG, interviews, event coverage, and field production.

Why It Helps

The UTX-P40 is useful when the microphone choice matters but the cable does not. A reporter mic, interview mic, or compatible XLR microphone can stay in use while the transmitter sends audio wirelessly to the receiver. That keeps the setup cleaner around cameras, talent, and moving crews.

The 0 dB to 48 dB attenuator range gives the operator room to manage different mic levels before the signal hits the wireless path. In real field work, that helps when switching between quieter speech, louder presenters, or microphones with different output behavior.

USB-C power support and AA battery operation give the transmitter flexibility. Batteries keep it portable, while USB-C power can be useful when the transmitter is used in a longer fixed setup or powered production environment.
