DIRAC LIVE® CALIBRATION
Warning: quadral GmbH & Co. KG does not accept any responsibility for possible damage caused by
operation or adjustment. Please read the instructions carefully.
DIRAC Live® is a software that enables you to counteract the negative room influence on the sound of your
loudspeakers.
It does not eliminate fundamental problems in room acoustics! Only the effects on the sound are reduced. For
a perfect sound experience, we therefore recommend that you design the room accordingly and carefully select
the position of the speakers.
You can set different target curves in the software and save up to four results.
We recommend you to firstly follow the specified target curve and use it. For further personal settings, you
should not set too much level in the bass range, as this can significantly limit the overall dynamics of the
loudspeaker. For example, frequency holes should not necessarily be completely filled - a slight depression is
usually hardly noticeable acoustically.
In the high-frequency range, a significant increase in level can even lead to damage! If you are unsure both your
specialist dealer or the quadral Service Team will be happy to assisting you.
The software for Windows® and Mac® is available for downloading at www.quadral.com/download . Make
sure that the speakers and your computer are connected to the same network. DIRAC Live® requires an
Internet connection for calibration.
Before you start measuring the speakers, the speakers must be set up correctly and the final listening position
must be set.
You can save multiple sound profiles. The profiles can be saved in the App under settings->DIRAC can be
selected.
A detailed DIRAC Live® manual is available at www.quadral.com/downloads .
