P hase Control
Phase Control is an innovative solution for the
phase lag in a multi-channel speaker setting. It
compensates the delayed bass to improve sound
synchronization.
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.
MCACC (Multi-Channel Acoustic Calibration System)
Create the optimum acoustic environment with
Pioneer's MCACC, developed with the expertise
of professional recording studios. The system —
complete with custom microphone — automatically
compensates for differences in speaker size, level and distance,
and equalises response.
Advanced MCACC
The Advanced MCACC uses a 3D calibration
method with even more precise measurements
by including the time axis. The A/V receivers
also feature a speaker polarity check for detecting
misconnected cables, and a reverb measurement display for
showing before/after calibration results. With the latest
improvement, the system automatically measures crossover
frequency — much easier than the previous manual setting –
and also lets you save measured data on USB memory for
cable-less PC viewing.
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.
Precision Distance
Precision Distance is an innovative, world first feature for
making millimetre-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.

Calibration
After Calibration
Speaker distance, sound pressure level, and
frequency response are all equalised.
Before Calibration
Speaker distance, sound pressure level, and
frequency response are all uneven.
The sound field is automatically
measured using the supplied mic.
Speaker sizes and number of
speakers are automatically detected.
