ST2 Pro logo

Adopted by countless studios around the world over the past 10 years the ST2 Pro is Trinnov Audio entry level professional audio processor it features our unique loudspeaker/room optimization technology, with up to four simultaneous processing channels.

IMPROVE YOUR STUDIO ACOUSTICS INSTANTLY

Trinnov’s ST2 Pro stereo processor is the ideal monitoring solution for cinema, post-production, broadcast and mastering studios. Sound engineers demand highly accurate monitoring to work with subtlety on effects, EQs, and dynamics.

It’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 environment and broadcast norms, therefore, increasing repeatability and consistency for better time efficiency.

EXPERIENCE TIME ALIGNMENT

 

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.

MEET YOUR LOUDSPEAKERS CHARACTERISTICS

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).

SOUND TAILORED TO YOUR ROOM

 

Trinnov’s sophisticated multi point algorithm can take into account the measurements of different positions to perform the optimization.
A higher weighting may be assigned to the most critical listening position(s), and lower weighting to the remaining points.

Therefore you can create instantly recallable listening positions letting you listen at the sweetest spot wherever you or the producer may sit in the room, making sure the production team hears the same content as you do.

    If your efforts in audio production have long left behind the bedroom music hobby stage and it’s vitally important that the work that leaves your studio is mixed and balanced to the highest professional standards, and will translate out there in the commercial world, the ST2 could be a tool that’s absolutely justified.

    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!

    Even if you got an unlimited budget for speakers and room treatment, there are specific phase issues you can’t get rid of, and for me, the Trinnov fixes those. So even if your room and speakers are states of the art, I believe you would see some serious improvement using a Trinnov.

    The mixes I’m doing sound better elsewhere, like my car. It’s a deeper more Hubble telescope view into the great sonic unknown. I’m not leaving home without it!

    The first time when I pushed play I was like way way what ? Not only the amplitude but the phase correction I mean to be honest I thought it was witchcraft!
