Measurement positions
Multiple microphone positions are used to understand the listening region rather than optimising one point in isolation.
Target curves
The calibrator can shape the desired in-room response, correction range and bass behaviour. The target should reflect the loudspeakers and room rather than a generic flat line.
Subwoofer integration
On processors such as AVM 90, multiple subwoofer outputs allow a more deliberate bass workflow than a single shared LFE feed.
Correction should not replace acoustics
ARC can improve consistency and tonal balance, but it does not replace correct loudspeaker placement, treatment, sufficient output capability or isolation.
Where ARC fits
It is particularly compelling for premium residential cinemas that want sophisticated correction without moving into a PC-based 20–32-channel processor architecture.
