INSTALLATION INSTRUCTIONS
LC372 SOUND REINFORCEMENT MODULE
Center Freq. (HZ)
Once you have selected a filter band, you can manually type in the frequency for the filter in this box.
This allows you to quickly set the filter to a very precise value. When using one of the parametric
bands, this frequency will control the center frequency of the filter. For the high-pass and low-pass
filters, this will set the cutoff frequency.
Gain (dB)
Use this box to adjust the amount of cut or boost for the filter. This only applies to parametric filters
and is not available for the high-pass and low-pass filters. You can also use the up and down arrow
buttons to increment/decrement the value. Positive numbers will add gain to the filter and negative
values will attenuate the filter.
Bandwidth (Oct.)
Use this box to manually input the bandwidth (in octaves) of the parametric filters. This will not affect
the high-pass or low-pass filters.
Filter Bypass
This checkbox is only present for high-pass and low-pass filters. When checked, the filter will be
bypassed.
Set Flat
Click this button to set the filter response curve to flat. This will remove any cut or boost applied us-
ing the parametric filters and set both the high-pass and low-pass filters to bypass.
Close
Click this button to close the window. All changes are made in real time, so you will not be prompted
to save any changes.
EQ Options Menu
This menu provides access to the lesser-used options that change the EQ display.
Legend Scale
This will change the number of dB represented by each division of the scale, thus changing the
vertical resolution of the graph. You may choose from 3dB/Div, 6dB/Div, 9dB/Div, or 12dB/Div.
Frequency Scale
This will change the way that the frequency (horizontal) axis is displayed. You can choose be-
tween Octave or Decade. Octave will display the axis in equal divisions while Decade will display
the response curve in a logarithmic scale.
0dB Location
This will set where on the graph the 0dB reference line is located. Available choices are Top, Mid
Upper, Center, Mid Lower, or Bottom.
Show Gain
This will enable or disable the gain response curve on the graph as displayed by a blue line.
Show Phase
This will enable or disable the phase response curve on the graph as displayed by a magenta
line.
