ROOM EQ
user’s manual

2
The electro-acoustic correction system M.A.R.S. corrects any faults in your audio system by taking measurements from a microphone placed at the
listening point.
This correction system takes into account your whole system: “speakers - room.” It irons out any incidents in the amplitude/frequency response co-
ming from re ections, absorptions or resonances in the listening room. It also corrects imperfections in the speakers.
The sound is transformed, any unpleasant resonance and other acoustic problems caused by your stereo are eliminated. The sound has pinpoint
accuracy and the base register has more impact. You can be sure you are getting the best out of your system whilst still preserving the necessary
neutrality of true hi-fidelity.
