1. How difficult acronyms like these make
your music & movies sound better...
Advanced MCACC:

2. Eh... what is Advanced MCACC?
Advanced MCACC stands for ‘Advanced
Multi-Channel Acoustic Calibration System’.
This technology uses a special microphone
that measures the acoustical output of the
AV-receiver/speaker combination in your
room, and then tells your AV-receiver how
to cope with it.
Seems like hot stuff for people in white
coats, but is it any good for me too?
It most certainly is. The reason: your room
is making a mess of the music you play in it.
Even acoustically optimised rooms cannot
escape the effects of the so called ‘standing
waves’.

A cool technology needs a cool logo, right?

3. Standing Waves!?
Standing waves occur when the sound waves
from your speakers interfere with those
reflected off the walls, floor and ceiling. The
actual audible effects are especially
cumbersome in the bass and highly depend
on the place in the room where you listen.
I see. But since I have no golden ears, this is
hardly a problem for me, is it?
Imagine a musician playing different notes on
a bass with exactly the same loudness. Now,
imagine listening in your room to the same
piece of music, but now with huge volume
differences - like double or half the original
volume level or even worse! - between the
notes. Sounds like a serious problem, no?
Two little ducks facing the opposite direction?
Nope, those green things are actually areas in a
room where standing waves are messing with
your music...

4. Advanced MCACC to the rescue!
It really is a serious problem. And you don’t
need golden ears to hear it. Not at all. It also
doesn’t matter whether you are listening to
rock, dance, classical music or to some
thunderous action flick. You just don’t want
the sound to be messed up.
So what is Advanced MCACC doing to solve
the problem?
First, the system precisely analyses the effects
of the standing waves, using a special
measuring microphone.
Second, Advanced MCACC deploys a
sophisticated equaliser to counteract most of
the deviations that are caused by the
standing waves.

5. Advanced MCACC: It’s getting
even better…
So Advanced MCACC kills the standing waves
in your room, making your music and movie
soundtracks sound significantly better than
before. That is certainly a good thing.
And yes, there is even more.
Advanced MCACC also offers you a bunch of
handy tools, such as automated speaker
settings (size, precision level, distance), phase
control, speaker polarity check and so on.
So Advanced MCACC is all you need? Could
be. But standard MCACC and MCACC Pro are
also worth checking…

6. All good things come in three…
MCACC takes care of all speaker adjustment settings
(size, level, distance and crossover). It also has Phase
Control and a 2D-equaliser.
Advanced MCACC offers the same possibilities as
MCACC and adds a 3D-equaliser, Auto Phase Control
Plus, Speaker Polarity Check, Standing Wave Control
and Subwoofer EQ.
MCACC Pro gives you all the possibilities of MCACC
Advanced plus Independent Dual Subwoofers
outputs, Full Band Phase Control & Precision
Distance.
