Dirac Live for Emotiva Processors
Your Listening Room
Even though Dirac Live is the most powerful automatic room correction system available today,
and it will produce a dramatic improvement in your listening experience in virtually every room,
you will still get the best results if you optimize your room and system configuration before you
run Dirac Live. We will be releasing several instructional videos covering this subject in detail, but
here are a few guidelines you can follow that will help you achieve the best results:
• In order to achieve a focused sound stage and proper imaging, it is very helpful if your room
and seating arrangements are as symmetrical as possible - from right to left. Ideally, your front
speakers should be the same distance from the wall behind them, the same distance from
their respective side walls, and at the same height. The ideal listening position will be located
along a line drawn from the center of the front of the listening room to the center of the rear,
and about one third to one half of the way back. Likewise, ideally the surrounds and rear
surrounds will be located symmetrically, and your center will actually be located in the center
of the front wall. While your particular listening room may limit your options, the closer you
can get to this goal the better.
• Ideally, your room itself should also be as symmetrical as possible acoustically. For example, if
you have a large window on your left wall, and a large tapestry on the right wall, you should
consider adding heavy curtains over the window.
• Listening positions directly against the rear wall, or in corners, should be avoided
• Your speakers should be positioned and angled so they produce the best imaging and the
smoothest sound before you run Dirac Live. (By avoiding obvious major problems, you will
enable Dirac Live to better focus on the smaller issues, and will end up with a more precise
room correction.)
• It is especially important that your subwoofer (or subwoofers) be properly positioned before
using any type of room correction. While Dirac Live will do a great job of evening out response
issues caused by room effects, it may not be possible for even the best room correction to
entirely eliminate strong nulls or room modes, and attempting to do so may cause other
issues. (Some locations, in some rooms, are just plain bad spots to locate a sub, and no
amount of room correction can correct them entirely.)
