ETM-2 Professional Acoustic Testing Microphone
(for ToneWinner audio products)
Original Testing Microphone
ETM-2 professional testing microphone is originally designed for ToneWinner’s audio products. Working with the room EQ function of the amplifier, this pen-shape testing microphone helps to auto-collect the sound information and auto-calibrate the sound field to optimize the sound performance.
Slim Pen-shape Design
The slim pen-shape design is sleek and efficiently reduces the impact to the sound field, which helps to capture accurate and detailed sound information and give reliable feedbac
Auto Recognition , Auto Collection
The auto-collection of sound information of the testing microphone and the auto EQ of the amplifier work together to auto-recognize the speaker amount, speaker distance, distance between speakers & main listening position and the best frequency crossover.

Automatic recognition
The ETM-3 test microphone is used to capture the acoustic characteristics of the room environment. Combined with the automatic room EQ function of the power amplifier system, the number and location of the connected speakers and subwoofers, the system's selected inflection point frequency, and the main listening distance are automatically identified.

Accurate Calibration
The testing microphone captures the frequency and latency of the noise, to reduce distortion caused by noise and auto-calibrate sound field so as to bring more accurate sound location & more realistic sound enjoyment.

Professional Calibration for Professional Experience
It help to auto-test and auto-calibrate the sound field to reduce or even eliminate the impact of standing wave and resonance to bring theater-like sound effect. It handles all ToneWinner processors & AV receivers.
