Trinnov 3D Measurement Microphone

To take full advantage of the impressive sound correction capabilities of the Trinnov NOVA, you need this special measurement microphone with four capsules. It not only measures frequency response but also detects the spatial positions of speakers and room surfaces.

Features

• Measurement microphone with four capsules arranged in a tetrahedral configuration

• Exclusively for Trinnov NOVA

• Ethercon connection

• Calibration data provided on USB stick

How the Trinnov 3D Measurement Microphone Works

The measurement microphone is one of the most important components of any speaker/room calibration system. Trinnov’s advanced algorithms rely not only on extremely accurate acoustic measurements but also on the ability to locate speaker positions and detect early reflections.

The Trinnov 3D microphone uses four microphone elements arranged in a precise tetrahedral configuration. Each capsule is individually calibrated at the factory (±0.1 dB from 20 Hz to 24 kHz).
The resulting microphone calibration file is included on a USB stick with the microphone. This file is installed on the Trinnov product being used, and all subsequent measurements are filtered using the calibration coefficients to ensure accuracy.

When measuring each speaker, the resulting sound waves pass through this microphone array and reach each capsule at slightly different times. The timing is used to triangulate the position of the speaker from which the sound originated. By testing the speakers one by one, a three-dimensional map of the speaker positions relative to the microphone (placed at the main listening position) is created.
