It features Trinnov's loudspeaker/room optimization technology, with its four simultaneous processing channels. The ST2 Pro supports any stereo speaker setup with 1 or 2 subwoofers

The Optimizer provides you with a unique set of data and comprehensive toolbox to get the absolute best from your speakers in any given room. With a single measurement, the Optimizer gives you both the direct response and the global acoustic response of your speakers in the room.

You can then define the target curve that will best meet your loudspeakers characteristics whilst optimizing its global acoustic response. The Optimizer automatically defines the filters that will achieve the required frequency response specified by your target curve. This is particularly useful in post-production studios to comply with SMPTE standards (X-Curve).

The Optimizer automatically time aligns your speakers with more precision than a human could achieve with a tape measure.

Time alignment alone makes a huge difference in terms of stereophonic image, but by working in the time domain and improving both the amplitude and phase response of the loudspeakers, the Optimizer achieves high-resolution stereophonic image and well-focused phantom sources simply not achievable otherwise.

The measurement microphone is one of the most critical components of a loudspeaker/room calibration system. Trinnov's sophisticated algorithms not only rely on very accurate acoustic measurements but also on the ability to localize speakers positions and to detect early reflection provenance. Trinnov's 3D measurement microphone is the result of our extensive research in 3D sound. We invested a significant amount of time to design a tailored measurement system that could gather very precise information regarding the spatial position of multiple sources.

This is called triangulation. Each of the four omnidirectional capsules is placed at the same distance from each other, forming a tetrahedral pattern. This allows us to localize each speaker's placement on both horizontal and vertical planes.

To achieve this challenge, the microphone consists of 4 capsules mounted at the top of thin brass tubes to avoid diffraction.
