The filter frequency selector can be set anywhere from 20 Hz to 20.0kHz. The Q setting
can be set to any value from 0.36 to 16.0. Higher Q values result in a steeper filter
slope—in the low and high pass configurations—and a narrower bandwidth in the
band pass and band eliminate configurations.
6. Low Band EQ
The Low EQ band operates on all frequencies below the selected
frequency. It has a:
•
frequency selector
—that sets the center frequency, from 20 Hz to 1.00 kHz.
•
gain control
—that raises or lowers the level of the selected frequency range. It can
be set anywhere from -15.0 dB to 15 dB.
The low band EQ is a shelving-type EQ that affects the level of all frequencies below
the selected frequency, as well as a narrow range of frequencies slightly above it. As
such, it requires no Q setting.
7. Lo-Mid Band EQ
The Lo-Mid EQ band is a parametric EQ that contains a:
•
frequency selector
—that sets the center frequency, from 20 Hz to 20.0 kHz.
•
gain control
—that raises or lowers the level of the selected frequency
range. It can be set anywhere from -15.0 dB to 15 dB.
•
Q
—that sets the width of the affect range of frequencies, from 0.36 to 16.0.
8. Hi-Mid Band EQ
The Hi-Mid EQ band is a parametric EQ that contains a:
•
frequency selector
—that sets the center frequency, from 20 Hz to 20.0 kHz.
•
gain control
—that raises or lowers the level of the selected frequency
range. It can be set anywhere from -15.0 dB to 15 dB.
•
Q
—that sets the width of the affect range of frequencies, from 0.36 to 16.0.
9. High Band EQ
The high band EQ operates on all frequencies above the selected
frequency. It has a:
•
frequency selector
—that sets the center frequency, from 1.00 kHz to 20.0 kHz.
•
gain control
—that raises or lowers the level of the selected frequency range. It can
be set anywhere from -15.0 dB to 15 dB.
The high EQ band is a shelving-type EQ that affects the level of all frequencies above
the selected frequency, as well as a narrow range of frequencies slightly beneath it. As
such, it requires no Q setting.
You can actually use the filter to
raise
the level of the selected frequencies by setting its
Q to a 0.90 or higher value.
Although this EQ is called the “Lo-Mid” band, its wide range of frequency values
means that you can use it to adjust the level of any frequencies in a signal, low
or
high.
Although this EQ is called the “Hi-Mid” band, its wide range of frequency values
means that you can use it to adjust the level of any frequencies in a signal, high
or
low.
