The ST2 HiFi has a built-in Ethernet network port which allows it to connect to your local ethernet network. VNC is the easiest solution to control the ST2 HiFi through the network from any tablet, computer or smartphone. The optional Wi-Fi USB dongle adds wireless capabilities. It allows the ST2 HiFi to connect to your existing Wi-Fi network, or to act as a Wi-Fi access point (AP).


Software upgrades can be purchased to benefit from new features and from the latest versions of the algorithms.


The measurement microphone is optional.

The most advanced stereo processor, room optimizer & DAC

It offers Trinnov’s patented loudspeaker/room optimization technology in a package specifically customized for Hi-Fi enthusiasts.

Trinnov's Unique Optimizer
Musical correction

The Optimizer loudspeaker/room optimization technology is at the heart of Trinnov’s products for professional studios, movie theaters, high-end Hi-Fi and home theaters. With its modern approach to acoustic measurements, analysis, and processing, it solves the Loudspeaker/Room acoustic equation.

Our research into capturing and reproducing complex three-dimensional sound fields began in 2001.In fact, the company name derives from “Tri” and “Innovation.” Hence, Trinnov Audio has meant “Innovation in 3D Audio” from when we first incorporated in 2003.One of the first things we discovered in our research is that complex 3D sound fields do not blend together seamlessly unless the sound heard from all of the speakers is extremely well-matched in both the amplitude and time domains.Our Optimizer was developed to achieve this goal with any combination of quality loudspeakers and has become recognized as the most advanced and powerful technology of its kind.

Trinnov is in our view the best room correction/speaker optimization solution on the market, the ability to do active crossovers and bass management combined with phase and amplitude correction is truly unique and all this concentrated in one High-End product.

Markus Wierl

Only in the acoustically optimized listening room can a playback system prove its sound quality. The Trinnov ST2-HiFi is intended to replace acousticians and extensive building projects and create true sound wonders.

Harald Wittig

Lowbeats.de (Germany)

The sound character is balanced, honest and in all situations very vivid, the music flows beautifully, the feet are teetering. A pleasant bridge between the professional and connoisseur world.

Raphael Vogt

Golden Ear Technology (USA)

The Sound is simply Extraordinary: for me, there is no question that this Trinnov Processor is absolutely fantastic!

Sandy Gross

VUmètre (France)

The ST2-HiFi is a powerful tool capable of sublimating any audio installation in any room, and with an interesting choice of configurations. Considering its price, it will be used in advanced installations, but its performance will be absolutely obvious in all cases.

Laurent Thorin


The Trinnov ST2-HiFi is the gateway drug in the world of corrected Optimizer sound that sounds somehow more real and authentic than virtually every other speaker and room correction. Despite the complexity of the technology everyone who has not only left hands should be able to handle the device.

Raphael Vogt

Mono & Stereo

Where Lyngdorf, Dirac and other solutions failed to impress me, The Trinnov ST2-HiFi is instrumental with any practical results, which transcends the musicality of any source

Matej Isak

AV Premium

Created for seamless integration of any sound in the room where it will be installed, this sophisticated electronics shines by offering a virtually unlimited flexibility.

Salvador Dangla

Haute Fidélité

The introduction of this device into a system is spectacular, and once the optimization is performed, it becomes impossible to do without its contribution. The benefits in terms of tonal perfection, the precision of the stereophonic image and cleanliness of listening is such that removing the ST2-HiFi correction is heartbreaking.

Patrice Philippe

Stereoplay (Germany)

We never had the opportunity to hear such musicality with any other digital acoustic correction.The richness and the clarity of reproduction made us rediscover the content selected.Everything finally seemed more true, as if our audio chain had been released from a burden. It may seem daring to say that the rendering of the Optimizer is a miracle, but we’re pretty damn close!
