Fusion 8100: User Manual
Note: The Fusion Advanced Room Correction System is very sophisticated, but no automated
system is totally foolproof. Unusual room acoustics, reflections, or unusual speakers can
cause it to get incorrect results. If the Fusion ARCS says that the phase of a particular speaker
is reversed, it is a good idea to double check your wiring, and the phase of your power amp
and speaker. If, however, you find that the Fusion ARCS is mistaken, you can safely ignore
its findings. If the Fusion ARCS says your subwoofer is out of phase, look for a phase reversal
switch on your sub (many have one) and try it the other way. If your sub has a variable
phase control, setting it to “180” is the same as reversing the phase. Moving a subwoofer to
a different position in the room may also result in a reversed acoustic phase. If your sub is
definitely phased correctly, or you have no way to reverse it, then just ignore that as well. If you
change any wiring or speaker positions at this point, please cancel out of the Fusion ACRS and
restart it from the beginning.
Notes (about setting subwoofers):
Since the Fusion Advanced Room Correction is controlling the bass management for your
subwoofer, it is usually optimum to set your sub itself to “flat”. If your subwoofer has a phase
setting, you should set it to “0 degrees” or “normal” (and not “inverted”). If your sub has a
built-in crossover that cannot be disabled, then set it to the highest allowed crossover point. If
your sub has a level control, setting it to a center position, or “0 dB”, is a good place to start. If
your subwoofer has special features for eliminating room nodes, or if you are using bass traps
or other advanced room correction devices, these adjustments should usually be made BEFORE
running the Fusion ARCS for best results.
Once you have finished viewing the information presented by the Fusion ARCS, press Enter to
continue. The Fusion ARCS will now play
another
series of test tones through each speaker. These
tones are used to make more precise measurements for each speaker (which will be used to
generate the calibration settings). After this series of test tones are done, the Fusion ARCS will
present you with another screen of information.
This time you will be prompted to
SAVE
the information by pressing Enter.
The fourth, and final, step to running the Fusion ARCS is to activate the calibration settings that
Fusion ARCS has created. On the current Menu screen, you can see the equalization settings that
are currently applied by the Fusion 8100. The options include Auto EQ, Manual EQ 1, Manual EQ
2, Manual EQ 3, and Flat. By moving the highlight to each choice and pressing Enter, you change
the current setting to that choice (and may hear what it sounds like). The highlighted option is the
one that is currently selected. (The Auto EQ settings will be highlighted and selected by default.)
You will be able to go back later and change your choice, and to manually adjust the settings
made by the Fusion Advanced Room Correction System if you prefer. You may also create up to
three full sets of custom manual EQ setting and choose between them. To make the calibration
curve generated by your new Fusion ARCS active, and apply it to your inputs, you must leave Auto
EQ selected as the active EQ choice.
