Its clear purpose is to provide a coherent and repeatable listening foundation for environments where every decision matters, from music studios to mastering, post-production, and broadcast control rooms.\u003c\/p\u003e\u003cp\u003eIn this \"Pro\" version, the integration of \u003cstrong\u003e4-channel processing\u003c\/strong\u003e and the associated Optimizer bundle allows for extended stereo configurations (active 2-way, systems with subwoofers, LCR, quad) while maintaining a studio workflow: measurements, before\/after comparison, adjustments, then recall of settings.\u003c\/p\u003e\u003ch3\u003eWho It's For: Studios, Control Rooms, and Mixing Rooms That Demand Reliable Listening\u003c\/h3\u003e\u003cp\u003eThe ST2 Pro targets professionals who need to \u003cstrong\u003ework quickly\u003c\/strong\u003e while maintaining reference-quality listening: mix and mastering engineers, sound editors, sound designers, broadcast operators, or post-production teams. In these contexts, room correction is not an \"effect\": it is a tool to reduce uncertainty, stabilize the stereo image, and ensure reliable choices in equalization, dynamics, and placement.\u003c\/p\u003e\u003cp\u003eIt is particularly relevant when the room imposes constraints (modes, early reflections, asymmetries), or when multiple people share the same system. Thanks to multi-point measurements and target curves, you can optimize a tight listening area (sweet spot) or a wider zone, depending on the use case (mastering vs. shared control room).\u003c\/p\u003e\u003ch3\u003eMeasurement, Correction, and Control: The Optimizer at the Heart of the ST2 Pro\u003c\/h3\u003e\u003ch4\u003eAcoustic Measurements and Time-Frequency Analysis\u003c\/h4\u003e\u003cp\u003eThe Optimizer uses \u003cstrong\u003eMLS (Maximum Length Sequence)\u003c\/strong\u003e measurement signals to capture the full impulse response of each speaker. This approach links frequency response to the time domain: it does not only correct \"the curve,\" but also identifies \u003cstrong\u003edelays\u003c\/strong\u003e, the impact of \u003cstrong\u003eearly reflections\u003c\/strong\u003e, and the contribution of \u003cstrong\u003elate reverberation\u003c\/strong\u003e. Trinnov's time-frequency algorithms isolate these components and compensate for them in a targeted manner, with a constant goal: preserving the speaker's signature while controlling the room's influence.\u003c\/p\u003e\u003ch4\u003eFIR\/IIR Correction, Phase, and Stereo Image\u003c\/h4\u003e\u003cp\u003eThe correction engine offers compensation based on \u003cstrong\u003eFIR and IIR filters\u003c\/strong\u003e to improve coherence between direct sound and reverberant field, while working on phase. In practice, this results in a \u003cstrong\u003emore stable stereo image\u003c\/strong\u003e, better-defined phantom sources, and clearer transient listening. Early reflections arriving shortly after the direct sound can be attenuated through appropriate processing (deconvolution), without artificially \"drying out\" the room by altering late reflections.\u003c\/p\u003e\u003ch4\u003eVisualization Tools, Target Curves, and Manual Adjustments\u003c\/h4\u003e\u003cp\u003eThe ST2 Pro includes graphical tools to compare multiple curves (per speaker, per measurement point, before\/after correction) to quickly validate a calibration. The tonal balance can be refined via a \u003cstrong\u003etarget curve\u003c\/strong\u003e to adapt the listening to a specification (very neutral work or slight personalization). Practical settings like \u003cstrong\u003emaximum boost\u003c\/strong\u003e and \u003cstrong\u003emaximum attenuation\u003c\/strong\u003e facilitate control over correction behavior, and equalization tools (manual FIR, graphic and parametric EQ) allow final \"by ear\" adjustments when necessary.\u003c\/p\u003e\u003ch4\u003eIntelligent Active Filtering and Remapping (with Optional 3D Microphone)\u003c\/h4\u003e\u003cp\u003eFor compatible systems, the calibration engine measures and analyzes impulse response, delays, and gains, then calculates optimized filtering aiming for the best compromise in overlap zones (frequency response, directivity, attack). The \u003cstrong\u003eTrinnov 3D measurement microphone\u003c\/strong\u003e (sold separately) uses a geometry of 4 omnidirectional capsules arranged in a pyramidal structure, enabling precise localization of speakers on horizontal and vertical planes. This measurement is at the core of \u003cstrong\u003e2D and 3D remapping\u003c\/strong\u003e features for more coherent reproduction when the listening geometry is not ideal.\u003c\/p\u003e\u003ch4\u003eMonitoring Controller Function: Daily Operation\u003c\/h4\u003e\u003cp\u003eBeyond acoustic optimization, the ST2 Pro functions as a true \u003cstrong\u003emonitoring controller\u003c\/strong\u003e: management of the main level, \u003cstrong\u003esolo\/mute\u003c\/strong\u003e of any channel, source selection, and downmix transposition. It is also possible to send \u003cstrong\u003eGPO\u003c\/strong\u003e commands to third-party equipment from the interface, facilitating integration in control rooms and studios.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eImportant\u003c\/strong\u003e: on-site setup and optimization are not included.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:2;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eBluetooth\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eNo\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:1;--wb-r:3;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eAdjustable parameters\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003emaximum boost, maximum attenuation\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eOn-site setup and optimization\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003enot included\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:2;--wb-r:4;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFinalization tools\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003emanual FIR, graphic and parametric equalizer\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Trinnov Audio","offers":[{"title":"Default Title","offer_id":54361775079699,"sku":"171035","price":5100.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/a11579216cbd9b4ab3d351ce4c86ee037cf43c07_TRINNOV_ST2_PRO_RIGHT.jpg?v=1792656718","url":"https:\/\/woodbrass.shop\/products\/trinnov-audio-st2-pro-optimizer-171035","provider":"Woodbrass.com","version":"1.0","type":"link"}
