Fusion 8100: User Manual
• Avoid moving around the room during the test. It’s best if you pick a spot that doesn’t block or
change the sound field to stand or sit while the test is running. The best place is in the rear of
the room towards the center of the wall. Avoid walking near the microphone during the test
(even if you don’t block any speakers) because reflections from your body will interfere with
the accuracy of the results. And, of course, avoid making noise during the test.
• If you rearrange your furniture, move your speakers, or add or remove reflective or sound
absorbing wall hangings (like big pictures or tapestries), you should re-run the Fusion ARCS
for best results.
• If you purchase new speakers, or change adjustments on your speakers or other equipment
(like the level controls on your tweeters or amps), you should run the Fusion ARCS again.
• The Fusion ARCS is powerful, but you will still get the best results if you start out with a good
room layout and good speakers. At a minimum, try to position speakers as symmetrically as
possible from left to right relative to the listening position. (Left and right speakers of each set
should be about the same distance to the sides of the listening position; the center should be
as near the center as possible. Perfect symmetry may not be possible in your listening room,
but the closer you get, the better your results will be.)
• In general, highly reflective rooms are not optimum in terms of sound quality, and even the
Fusion ARCS may not be able to completely correct for the acoustic properties of an overly
“live” room.
Third, run the Fusion Advanced Room Correction System.
To run the Fusion ARCS, press the Menu button (to get into the menu system), select Setup, move
down to Auto Room EQ, move right to Auto Room EQ, and press Enter. Press Enter again when
asked, and again when asked after passing ambient level check. (If you “fail ambient” it means that
the Fusion ARCS thinks your room is too noisy, so look for appliances or other things making noise
and quiet them.)
Note: If the Fusion ARCS fails to run, ensure that your microphone is plugged in to the correct
input (the Cal jack on the front of the Fusion 8100).
The Fusion ARCS will now play a series of test tones through each of your speakers in turn. This
will take several minutes; do not interrupt the sequence. If you don’t have a full seven speakers
plus a subwoofer, the Fusion ARCS will still take several seconds to “test” each of the ones that
aren’t there (to verify that they really aren’t there); don’t worry, the Fusion ARCS won’t get stuck.
After the first series of test tones are done, the Fusion ARCS will present you with a screen
summarizing what it has found out so far (the presence, distance, and phase of each of your
speakers) and wait for you to press Enter (it will eventually continue by itself if you do not).
