How difficult acronyms like these make your music & movies sound better...

Advanced MCACC:

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?

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 withyour music...

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.

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…

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. Go to www.pioneer.eu to view all Pioneer AV-receivers with MCACC, MCACC Advanced & MCACC Pro.
