“The Trinnov remains the greatest single bit of mix equipment I’ve ever used. Nothing else improves every other bit of gear in the studio like Trinnov does. Microphones, outboard and plugins are all improved!”

– Jan Stan Kybert, (Paul Weller, Oasis, Massive Attack)

What is Room Correction and Speaker Optimization?

The acoustics of a room affects the sound that you hear coming from your speakers which in turn affects the way you manipulate your mix. Traditional methods of acoustic treatment will help to control this but there are still artefacts that cannot be corrected by acoustics alone. Trinnov Audio has developed a range of stereo and surround optimisers using the latest DSP real-time processing that will improve the accuracy of your room through your speaker system.

Trinnov has applied the results of breakthrough research in loudspeaker/room acoustics to create a new generation of loudspeaker processors, setting a new benchmark for accurate sound reproduction. The Trinnov Optimizer takes mix translation to the next level.

While the room and the loudspeakers need to be analysed and eventually treated separately by most technologies on the market, the Optimizer considers and addresses every aspect of the reproduction system in its acoustic environment at the same time. Problems are identified, cross-analysed and compensated with the most efficient and best-sounding compromise.

Design

Trinnov Audio’s ST2 Pro stereo processor is the ideal monitoring solution for music production, broadcast, mastering studios and stereo TV/film post production. It’s unique loudspeaker and room correction technology will take your audio monitoring chain to the next level, resulting in mixes that translate better through various listening environments, therefore, increasing repeatability and consistency.

The Optimizer automatically time aligns your speakers with a higher 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 images and well-focused phantom sources simply not achievable otherwise.

Unique Phase Correction

The Trinnov ST2 provides highly accurate monitoring by improving the phase response of every speaker, offering a wider stereo image and more focused phantom sources.

The Optimizer is the only system on the market that not only compensates for the phase response of a loudspeaker but actually shows you what it does with acoustic graphs where you can see the before and after phase response for any given measurement position.

Early Reflections

The Trinnov Audio ST2 Pro Optimizer analyses the measurements in the time-frequency domain to identify early reflections, depending on their amplitude, frequency, direction and arrival time.

The ST2 then takes this information and makes corrections where necessary. After this process, each loudspeaker’s response is “clean” from early reflections.

Room Energy

In this second stage the Optimizer analyses the measurements in the frequency domain only (the response of the system in steady state).

Compensation of Resonance Modes (in the low range): the Optimizer identifies resonance modes in the range where they can be clearly differentiated, roughly up to 300 Hz. It applies individual filters to compensate each resonance mode.
Smoothing of the reverberation (in the mid and high range): The Optimizer analyses the room’s frequency response, related to the coloration of the room’s reverberation. Another filter is applied to smoothly compensate for this coloration.

Configurations

Trinnov’s unique software modules, the Processor and the Optimizer can run simultaneously in the ST2-Pro:

The Processor manages the core loudspeaker processing functionality, such as routing, delays, gains, crossovers and manual EQs (graphic and parametric).
The Optimizer module offers unique room EQ features with Multi-point Measurements, Target Curves and Automatic Phase Optimization.

The ST2-Pro can be controlled via a touch-screen, via a monitor + mouse, from any computer (PC or Mac) via a VNC client, through the network, or via the optional GPIO interface.
