Digital audio processing for high quality sound

Sony’s advanced digital audio processing technology assures high quality sound with improved transient response performance.

Simple Channel Setting with NFC SYNC

One-button SYNC on the receiver scans and selects the cleanest channel. Use near-field communication to touch the two devices together for easy syncing.

Reduced Size and Weight

The UTX-B40 Bodypack is around 20% smaller than the previous generation, so you can avoid a bulky wireless system and remain lightweight.

Auto Gain Mode

Auto Gain mode has you covered when you are unsure of the talent’s volume, setting the gain moderately high automatically, then using a limiter to help prevent distortion.

+15 dB Boost for off-mic Audio

The +15 dB boost resets the gain when the microphone is not near the person’s mouth to avoid insufficient audio levels during interviews.

Line Input

Set the appropriate input levels with MIC/LINE switching levels and adjustable attenuators.

Transmitter Frequency Sent to Receiver

It’s easy to set up multiple receivers in combination with one transmitter. NFC communication relays transmitter settings such as frequency and compander mode directly to the receiver.

Headphone Monitor Output

Sound can be monitored directly from the receiver even if the camera doesn’t have a headphone output, the wireless receiver does.

Variable Mute

Pressing the MUTE button silences the audio output from the Transmitter, while the Variable Mute function lets you determine whether the audio is muted for different operating states.

High-Visibility OLED Display

You’ll see operating status instantly and accurately, regardless of whether the unit is being used indoors or outdoors, with the quick response of the OLED display.

USB Power

For long-term use or low-battery emergencies, the transmitter can draw DC power from the USB interface.
