Eversolo EM-01 calibration microphone

The Eversolo EM-01 is an omnidirectional measurement microphone designed for acoustic calibration of listening rooms, studios, or home theater systems. Engineered to work optimally with the brand's streamers, it provides a precise tool for analyzing the frequency response, resonances, and overall behavior of an audio system in its real-world environment. Thanks to its individual calibration file and plug-and-play USB-C connectivity, it delivers reliable measurements suitable for both audiophiles and sound professionals.

A microphone dedicated to acoustic calibration

Developed for optimizing hi-fi and home theater systems, the EM-01 neutrally captures the acoustic characteristics of a room, enabling correction via DSP, equalization, or integrated room correction systems. It is specifically designed to work with compatible Eversolo network players, while also remaining usable with third-party measurement software.

Each unit comes with a unique calibration file, ensuring greater accuracy during measurements and improved reliability of applied corrections.

High-precision electret capsule

The microphone incorporates a 6 mm electret capsule combined with omnidirectional directivity, ensuring homogeneous 360° pickup. This design allows for accurate measurement of the room's response without directional bias, essential for acoustic analysis.

Its wide frequency response of 20 Hz to 20 kHz covers the entire audible spectrum, while its high sensitivity allows it to capture the slightest variations in sound.

Low noise and high SPL tolerance

The EM-01 boasts an extremely low noise level, ensuring readable measurements even in quiet environments. It can also withstand high sound pressure levels, making it suitable for measurements in loud listening environments or studios.

This low noise/high SPL combination ensures excellent dynamic range for accurate acoustic analysis.

USB-C connectivity and broad compatibility

Powered directly via USB, the microphone requires no phantom power or external audio interface. Its plug-and-play USB-C connection makes it compatible with a wide range of environments:

• Windows / macOS / Linux computers
• iOS/Android smartphones and tablets
• Network streamers and players
• REW or Dirac type measurement software

It can therefore be used for both hi-fi calibration and acoustic measurements in studio or broadcast settings.

Sturdy construction and accessories included

The aluminum alloy chassis ensures rigidity, lightness, and durability. Its compact design facilitates precise positioning at the listening point, particularly with the included tripod.

Mounting accessories are included to allow for quick installation in a home or professional environment.
