Standing Wave Control
Acoustic standing waves occur when the sound waves from
your speaker resonate with those reflected off the walls.
Depending on the speaker placement, your listening position or
the shape of the room, standing waves have a negative effect on
the overall sound, especially in certain lower frequencies.
Standing Wave Control effectively decreases resonance and
prevents inaccurate EQ-setting calibration.

Subwoofer Equalizer
This new EQ feature allows you to adjust the subwoofer tone.
For Auto MCACC, the subwoofer EQ is automatically adjusted
with EQ type ALL CH ADJ, while manual adjustment is available
with EQ type SYMMETRY and FRONT ALIGN. As with other EQ,
the manual adjustment can be done on the AV receiver’s GUI.
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.

Precision Distance
Precision Distance is an innovative, world’s first feature for
making millimeter-level manual adjustments to speaker
distance. You can easily duplicate a skilled installer’s precise
positioning with the help of a level gauge shown on the display.
