Fusion 8100: User Manual
With an old style "graphic equalizer", you were given ten (usually) separate frequency controls,
each of which worked like a tone control (you could turn that band either up or down in level).
A parametric equalizer is infinitely more flexible. For each channel in each EQ bank you are given
eleven control bands. For each control band, you may choose the center frequency (Fc), how
narrow or wide a range of frequencies is affected (Q), and then finally the level for that band.
For example, to boost a wide range of frequencies in the lower voice range, you might set one
band to a Center Frequency of 600 Hz, and a Q of 0.5 (higher Q numbers mean narrower bands;
lower Q numbers mean wider bands). At that point you could use the Gain slider for that band to
turn those frequencies up. To reduce a sharp resonance around 33 Hz, you might set another band
to a Center Frequency of 33 Hz, and a Q of 7, and then set the Gain slider for that band to -6 dB.
Each frequency band can be set over the full range of audio frequencies, the Q for each can be set
between 0.25 (very gradual/wide) and 24 (very sharp/narrow), and the gain of each band can be
set anywhere between +3 dB and - 15 dB.
Note: The Auto EQ bank shows the EQ settings automatically entered by the Fusion Automatic
Room Correction system. However, Fusion Advanced Room Correction makes other changes
and settings that are NOT visible on this screen. While you may raise or lower the Gain settings
of specific bands on this screen to alter the automatic settings, setting all bands to flat on this
screen will NOT result in a flat response curve, and copying the settings on this screen into a
Manual EQ screen will NOT produce an equivalent response curve in that Manual EQ bank.
