SONY Wireless Handheld Mic with Built-in Transmitter (14)

SONY Wireless Handheld Mic with Built-in Transmitter (14) is a wireless handheld microphone transmitter built for ENG, interviews, documentaries, weddings, remote production, and general field audio work. From the supplied source, the Sony UTX-M40 uses a dynamic capsule, uni-directional pickup, and operates on the UC14 frequency range from 470.125 to 541.875 MHz.

This is a straightforward handheld option for reporters, presenters, and interview use. The transmitter is already built into the microphone body, so the person speaking can move freely without a cable running back to the camera or receiver position.

Why It Helps

The UTX-M40 is practical when the production needs a wireless handheld mic without adding a separate bodypack. For field interviews, stand-ups, event coverage, and presenter work, it keeps the microphone simple for the person holding it and clean for the operator managing the camera or receiver.

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

Setup stays quick as well. The OLED display gives clear status feedback, NFC sync helps with fast channel setting, and USB-C power support gives another option when the mic is used in longer or more controlled production setups.

• Built-in transmitter design keeps the handheld microphone cable-free
• Dynamic unidirectional capsule for focused speech capture
• Audio attenuator control from 0 dB to 21 dB in 3 dB steps
