SONY Wireless Handheld Mic with Built-in Transmitter (90)

SONY Wireless Handheld Mic with Built-in Transmitter (90) is a wireless handheld microphone transmitter built for ENG, interviews, documentaries, weddings, remote production, and field audio work. From the supplied source, the Sony UTX-M40 uses a dynamic capsule, uni-directional pickup, and operates on the UC90 frequency range from 941.625 to 959.625 MHz.

This is a clean handheld option when the speaker needs to move freely without a cable running back to the camera or receiver. The transmitter is built into the microphone body, so the setup stays simple for reporters, presenters, and interview subjects.

Why It Helps

The UTX-M40 is practical when a production needs a wireless handheld mic without adding a separate bodypack. For interviews, stand-ups, event coverage, and presenter work, it keeps the mic familiar for the person holding it and easier to manage for the operator.

The dynamic unidirectional capsule helps keep the pickup aimed toward the speaker. That matters in live locations, especially around crowd noise, room reflections, or outdoor ambience where the microphone needs to stay focused on speech.

Setup stays straightforward. The OLED display gives clear status feedback, NFC sync helps with fast channel setting, and USB-C power support gives another option for longer or more controlled production setups.

• Dynamic unidirectional capsule for focused speech capture
• Audio attenuator control from 0 dB to 21 dB in 3 dB steps
