The Iconic 3D Measurement Microphone
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.
Our 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. The file is installed on the Trinnov product being employed and all the subsequent measurements are filtered through the calibration coefficient to ensure accuracy.
The Optimizer captures a huge amount of acoustic information in each measurement and performs time/frequency analysis to better understand and characterize the behavior of the speakers in the room. (Indeed, without the time domain, frequency response alone shows irregularities in response but doesn’t provide enough information to correct the errors properly, with the appropriate method.)
Pro Audio Solutions
The highly detailed information is then processed using Trinnov’s proprietary algorithms, providing a full acoustic analysis of the room and revealing more information than any other automatic system. As an example, the acoustic graphs generated by the Optimizer for each measurement point include the phase response, group delay, and impulse response of each speaker, all of which are important to understand what is occurring in the room over time.
Most people understand that time-aligning speakers is important; but the point Trinnov has made since 2005 is that time-aligning frequencies is also essential for improving sound staging and transient reproduction. This is an area where passive acoustic treatment, although critical, cannot help.
The sophistication of acoustic analysis performed by the Optimizer may sound like overkill for the consumer world. However, Trinnov is understandably proud of its pro audio background and believes consumers deserve no less. The Optimizer simply can solve problems that other systems cannot, and this is an area where Trinnov reigns supreme. Fortunately, Trinnov introduced a setup wizard to simplify the initial measurement and calibration process
However, the manufacturer remains clear about the fact that every system is unique. Many acoustic parameters come into play, whether they are related to room acoustics, electro acoustics or psycho acoustics. The best possible results can only be achieved by a trained ear and experienced calibrator. This fact is not specific to Trinnov but is true for any system, regardless of its sophistication.
Trinnov really shines regarding the level of integration of the Optimizer within their products. The Optimizer doesn’t require external equipment beyond the microphone. It takes only a few clicks to make any system sing, whether you do it locally or remotely over the internet. Since the measurement data resides in the machine itself, subsequent tweaks are easily made, all with 64-bit floating-point precision.
All Trinnov products include the Optimizer technology.
