Trinnov 3D measurement microphone

To utilize the impressive sound correction of the Trinnov NOVA, you need this special measurement microphone with four capsules. It enables not only the measurement of the frequency response but also the detection of the spatial position of the speakers and walls.

Features

• Measurement microphone with four capsules in a tetrahedral arrangement

• Only for Trinnov NOVA

• Ethercon connection

• Calibration data on USB stick

How the Trinnov 3D measurement microphone works

The measurement microphone is one of the most critical components of any loudspeaker/room calibration system.

Trinnov’s sophisticated algorithms rely not only on extremely accurate acoustic measurements but also on the ability to localize the speakers’ positions and to detect early reflections. The 3D microphone uses four mic elements in a precise tetrahedral arrangement. Each capsule is individually calibrated at the factory (±0.1 dB from 20 Hz to 24 kHz)

The resulting microphone calibration file is included in the microphone’s box on a USB stick. This file is installed in the Trinnov product being employed and all subsequent measurements are filtered through the calibration coefficients to ensure accuracy.

As each speaker is measured, the resulting sound waves pass through this array of microphones, hitting each one at a slightly different time. Based on this timing, we can triangulate the location of the speaker from which the sound arrived. By testing each speaker in turn, we build a three-dimensional map of where the speakers are relative to the mic (which is placed at the main listening position).
