MCACC Auto Room Tuning
Create the optimum acoustic environment with Pioneer’s MCACC (Multi-Channel Acoustic Calibration System), developed with the expertise of professional recording studios. With the custom microphone, the system automatically compensates for differences in speaker size, level and distance, and equalises response.
Reflex Optimizer
When using Dolby Atmos-enabled speakers, high directivity sound from the unit reflects off the ceiling, while low directivity sound directly reaches the ears. The different pathways cause a phase shift, making the sound feel uncomfortable. The Reflex Optimizer which uses the Phase Control technology adjusts this shift, and improves the localisation of the sound image by aligning the frequencies with those of the floor speakers, creating the ideal reproduction environment.
