Low EQ Q Control (StudioLive
24.4.2 only). Sets and Displays
the Q of the Low Frequency
Band.
This encoder sets, and the meter
displays, the Q for the Low band.
The Q is the ratio of the center
frequency to the bandwidth.
When the center frequency
is constant, the bandwidth is
inversely proportional to the Q,
so as you raise the Q, you narrow
the bandwidth.
Low EQ Gain Control. Sets and
Displays the Gain Attenuation or
Boost of the Center Frequency.
This encoder sets, and the meter
displays, the gain cut or boost
at the center frequency for the
Low band. The level of the center
frequency can be set between
-15 and +15 dB.
Low Shelf EQ Button. Turns on
the Low Shelving EQ for the
Selected Input or Output Bus.
When the Shelf button is not
engaged, the Low band is
parametric. Enabling the Shelf
button turns the Low band into
a low-shelving EQ that alters,
by a fixed amount, a band of
low frequencies at and below a
user-selected shelving frequency.
Power User Tip: A Low Shelving
EQ is like a bass-control knob
on a stereo. In this mode, the
Center Frequency control
selects the shelving frequency.
Low-Mid EQ On/Off Button.
Turns the Low-Mid EQ On/Off for
the Selected Input or Output Bus.
This button activates the
equalizer’s Low-Mid band for
the selected input or output.
The button will illuminate to
indicate control is active.
The Low-Mid EQ is available for
all input and output buses.
Low-Mid EQ Frequency
Control. Sets and Displays the
Center Frequency of the Low-Mid
EQ.
This encoder sets, and the meter
displays, the center frequency
for the Low-Mid band. You can
adjust the center frequency from
75 Hz to 1.2 kHz.
Low-Mid EQ Q Control
(StudioLive 24.4.2 only). Sets
and Displays the Q of the Low
Mid Frequency Band.
This encoder sets, and the
meter displays, the Q for the
Low-Mid band. The Q is the
ratio of the center frequency
to the bandwidth. When the
center frequency is constant,
the bandwidth is inversely
proportional to the Q, so as
you raise the Q, you narrow the
bandwidth.
Low-Mid EQ Hi Q Button
(StudioLive 16.4.2 only). Enables a
Narrow Bandwidth for the Low-Mid
band EQ on the Selected Input or
Output Bus.
Q is the ratio of the EQ band’s
center frequency to its bandwidth.
With a constant center frequency,
higher Q values indicate a narrower
bandwidth. By default, the Low-
Mid EQ is set to a low Q of 0.55.
When the Hi Q button is engaged,
the bandwidth will narrow to 2.0
to proved more exact control.
Low-Mid EQ Gain Control. Sets
and Displays the Gain
Attenuation or Boost of the
Center Frequency for the
Low-Mid Band.
This encoder sets, and the meter
displays, the Gain cut or boost at
the center frequency of the Low-
Mid band. The level of the center
frequency can be set between
-15 and +15 dB.
