SR-8100: User Manual
WIth the 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 innitely more exible. 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 nally 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). 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 PEQ frequency band can be set over the full range of audio frequencies, the Q for each
can be set between 0.25 (very gradual) and 24 (very sharp), and the gain of each ban can be set
anywhere between +3 dB and - 15 dB.
Note: The Auto EQ bank shows the EQ settings automatically entered by the Sherbourn
Automatic Room Correction system. However, Sherbourn 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 specic bands on this screen to alter the automatic settings, setting all
bands to at on this screen will NOT result in a at 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.
