TRINNOV ST2-HIFI

DIGITAL PROCESSOR
  • Up to 6 customisable profiles and 29 user presets
  • Automatic alignment of delays and gains for every driver
  • Automatic optimization of amplitude and phase response according to target curves

Typical rooms introduce up to 10dB of distortion in the frequency response. The Trinnov’s ST2-HiFi solves the acoustic equation. It takes your high-end system to a whole new level of accuracy, from high-fidelity to acoustic-fidelity.

HIFI OPTIMIZER

The Trinnov ST2 HiFi is fundamentally a room and speaker optimiser, with AD/DA converter. The feature set and innovative capabilities extend well beyond the competition, for the ultimate hi-fi experience.

 

Room acoustics are anything but transparent. In fact, when you consider your system as a whole, the room is the only element that introduces large amounts of distortion. Therefore, as long as the room is adding its own sound to the music, the fidelity of your system is highly compromised. Trinnov’s breakthrough research solves this complex equation. The ST2-HiFi loudspeaker/room optimizer takes your system from high fidelity to acoustic fidelity.

 

The ST2-HiFi uses MLS signals to measure the full impulse response of every loudspeaker in the room. This adds the time dimension to the frequency response, and enables the Optimizer to see the full picture of the loudspeaker’s behavior in the room.

 

Trinnov’s state-of-the art time-frequency analysis algorithms identify room modes, first reflections and late reverberation. Every acoustic aspect is analyzed and compensated with a specific technique. All the subtlety of the Optimizer resides in knowing which defects can be corrected with acoustic transparency.

 

The ST2’s intelligent acoustic engine automatically computes FIR and IIR filters to improve the consistency of direct sound against late reverberation. Full-phase, time domain techniques are applied compensating for the loudspeaker’s group delay and for very early reflections (deconvolution), while later reflections are left untouched.

 

The loudspeaker’s sound (including the early reflections) and the room (energy response) are separately equalized, opening up the listening window. Trinnov corrects the tonal balance to obtain a neutral timbre for every speaker. If a specific target curve is defined, the optimization algorithms automatically compute the filters to reach it.

 

The ST2-HiFi also corrects the phase response by applying FIR filters that work in the time domain. The result is a high resolution stereophonic image with well-focused phantom sources.
