The calibration starts by understanding the loudspeaker
Trinnov’s 3D microphone captures the position of each loudspeaker as well as its acoustic behaviour. The reference measurement establishes distance, azimuth, elevation, level, delay, amplitude response and phase response.
That geometry is why Optimizer can feed other Trinnov technologies such as Remapping instead of treating each loudspeaker as an anonymous frequency trace.
Time and phase matter alongside amplitude
A frequency-response peak is only one way a system can be wrong. Arrival time, phase behaviour and crossover interaction can all affect clarity, localisation and transient behaviour even when the steady-state magnitude response looks acceptable.
Optimizer can work in both time and frequency domains, including phase optimisation, rather than limiting correction to conventional minimum-phase EQ.
Multiple measurements describe a listening area
The reference seat remains the geometric anchor, but additional measurements can be weighted to improve consistency across multiple seats. The goal is not to make every seat mathematically identical; it is to find a controlled compromise across the listening area.
Measurement strategy therefore becomes part of the calibration judgement rather than a fixed “take nine points” ritual.
Target curves are design tools
Optimizer can calculate powerful filters, but the desired tonal balance remains a human decision. Target curves, correction bandwidth and post-Optimizer alignment should reflect the loudspeakers, room acoustics and intended playback level.
A perfectly horizontal response is not automatically the most natural or appropriate target in a cinema.
Active crossovers can sit inside the same optimisation workflow
Altitude processors can manage multi-way active loudspeakers, aligning driver sections before the complete system is optimised. This is a major reason channel count can grow beyond the visible Atmos layout.
The capability is powerful, but it transfers crossover responsibility into the processor and demands careful commissioning.
Optimizer does not replace room design
No processor can create missing acoustic isolation, add subwoofer displacement, remove severe mechanical noise or fix a loudspeaker firing through an obstruction. Passive acoustics, sensible speaker placement and adequate system capacity still come first.
The best results come when the processor is used to refine good architecture rather than to rescue poor architecture.
