On top of Advanced MCACC features, MCACC
Pro goes a step further by analyzing the phase
and group delay characteristics due to network
filtering to precisely control phase differences
between speakers. This correction is also performed between
channels, providing a smooth flow of sound as if all delivered
from the same type of speaker. Other features include
independent correction for dual subwoofers, and speaker
position adjustment in 1-millimeter increments. MCACC Pro
corrects phase differences in all ranges and all channels, from
phase difference in the original audio material to the sound
emitted from the speakers.
Independent Dual Subwoofer Output
When connecting an additional subwoofer to increase the
bass, the two subwoofers may not be at a same distance. In
such a case, cancelling out of the bass may occur and
prevent you from perceiving the full effect of the additional
subwoofer. MCACC Pro supports independent adjustment for
each subwoofer, offering optimal performance for a dual-
subwoofer setup. You can enjoy free placement of your
subwoofers.
Full Band Phase Control
The further advanced Full Band Phase Control technology
focuses on the group delay in the speaker network filter, and
compensates with special digital signal processing (DSP), to
adjust the phase of each unit as well as the group delay for
each speaker. Full Band Phase Control gives multi-range
speakers the sound coherence of full-range speakers, while
retaining the wide frequency range advantage.
Bass Management System for Dolby Atmos Enabled Speakers
When using Dolby Atmos enabled speakers, the low-
frequency components are usually all redirected to the
subwoofer. Since this will include frequencies featuring
directivity, the resulting sound lacks a seamless feel. MCACC
Pro redirects the low frequency component with
directionality to the floor speaker below the Dolby Atmos
enabled speaker element, and the lower frequency
components to the subwoofer. This optimal signal
distribution creates superior sound localization, maximizing
the advantage of Dolby Atmos content.
