Unveiling the Trinnov ST2 Pro: Revolutionizing Monitor Correction

Is Trinnov’s powerful hardware system the last word in monitor correction?

In the realm of audio perfection, the Trinnov ST2 Pro stands as a revolutionary force. This review delves into its nuances, contrasting it with other solutions like Sonarworks’ Reference 4.

Understanding the Acoustic Dilemma:

Monitors and enclosed spaces pose dual challenges — irregular monitor responses and the unpredictable impact of room acoustics. Trinnov, akin to Sonarworks and others, addresses these challenges, aiming for a consistent and accurate monitoring experience.

Trinnov’s Unique Approach:

Trinnov’s hardware solution differs significantly; it’s a 2U rackmount box, bypassing the need for host-based processing. While this raises costs, it empowers the ST2 Pro with substantial processing capabilities, a crucial advantage.

The Role of Trinnov’s 3D Mic:

Accompanied by a sophisticated 3D mic, the ST2 Pro captures not only amplitude and arrival time but also directional information. This mic array enhances the system’s understanding of the 3D soundfield, differentiating between direct sound, early reflections, and reverberation.

In-Depth Measurement and Optimization:

Trinnov goes beyond traditional measurements, employing a Maximum Length Sequence (MLS) stimulus signal. This method allows for detailed analysis, discerning frequency and phase responses. The ST2 Pro can measure at multiple positions, offering flexibility and personalized optimization profiles.

Achieving Balance:

The ST2 Pro achieves remarkable amplitude correction, illustrated by the flattened frequency response in tests. However, limitations exist, notably in handling room-induced challenges like standing-wave resonances.

The Power of Phase Equalization:

Where Trinnov excels is in phase equalization, a feat not easily replicable by traditional methods. Correcting phase responses below 100Hz might introduce noticeable latency, but the benefits in impulse response focus are impressive.

User Interface and Control:

Configuring the ST2 Pro involves various options, from connecting a keyboard and monitor directly to using a VNC client interface. The system offers extensive customization, but users are advised to tread cautiously in advanced settings.

Subjective Performance:

In practical terms, the ST2 Pro elevates the performance of even high-quality monitors. The tonal balance, stereo imaging, and detail retrieval see significant improvements, providing a more accurate representation of audio material.

Considerations and Conclusions:

While the Trinnov ST2 Pro comes at a premium, it proves justified for professionals seeking top-tier monitoring. It requires an investment of time and effort to grasp its capabilities fully, but the benefits are substantial — a reliable monitoring system and profound expertise in acoustics.

In conclusion, the Trinnov ST2 Pro isn’t just a tool; it’s a transformative force for studios committed to delivering audio excellence. For those past the hobby stage, where professional standards are paramount, the ST2 Pro emerges as a justified and indispensable asset.
