Accurate room measurement for your Eversolo system. The EM-01 is an omnidirectional measurement microphone designed to work with Eversolo streamers for evotune™ acoustic calibration of your listening room. It also works with popular measurement software such as REW and Dirac, making it equally useful for speaker measurements and on-site acoustic assessments. Each EM-01 comes with its own unique calibration file for highly accurate measurement data.
High-Sensitivity Pickup
A 6 mm electret condenser capsule with an omnidirectional pattern offers -13 dBFS sensitivity and a 20 Hz–20 kHz frequency response (±1 dB with the calibration file applied), capturing every detail faithfully.
Low Noise, High SPL Handling
A noise level as low as -84 dBFS (A-weighted, +30 dB IGPA) keeps measurements clean, while a maximum sound pressure level of 130 dB SPL means it stays distortion-free even at high volumes.
24-bit/48 kHz Sampling
A high-precision 24-bit ADC sampling at 48 kHz delivers clear, detailed captures.
Plug and Play
The USB Type-C interface supports the UAC 1.0 protocol and is compatible with Windows, macOS, iOS and Android. A lightweight yet durable aluminium-alloy body (47 g) is supplied with a desktop tripod, holder, windscreen and cables for both computer and mobile use.

To Keep your equipment safe these are some best practices to note. Please be advised that this is only to reduce the risk of misuse and is not an exhaustive list.
Speakers
- Speaker terminals are marked red and black, ensure your amplifier to the speakers are wired on the same colours
- Ensure no loose speaker wire from the red touches a loose wire from the black as this will lead to a short circuit and damage either the speaker, the amplifier or both.
- Not all speakers are designed to play at max volume, kindly consider the pairing of your amplifier and speakers
- Speaker cabinets cannot be replaced please handle with care.
AV & Stereo Amplifiers
- If your amplifier has HDMI ports, ensure all devices are off before plugging in the HDMI cable
- Turn off the amplifier before swoping out or adding speaker cable
- Amplifiers generate heat, place them in a well ventilated space. if possible avoid having anything on top of the unit.
- adding a surge protector can assist with power dips which are likely to damage your devices. Isotek and Furman are industry standard.
- Dusty environments can sometimes lead to accumulation of dust in the electronic components that might affect heat regulation
