• Filter: Click to apply filtering to each independent Mic Input.
° Start by clicking Add Filter
° Adjust the filter placement by moving the point along the grid (Hz, dB/deg).
` Alternatively, press the Table View button to toggle the display between graph view and table
view. Table view displays filter settings in table format for all filters configured for the input
channel. Clicking on a row in table view selects the filter, displays the current settings for that
filter, and allows you to edit the values in the setting fields. Changes made in the setting fields
are immediately reflected in the table.
° To adjust the Active Filter, click the fields along the top row.
` Active Filter: Selects the filter to adjust
` Type: Sets the type of filter applied
` Frequency: Use the Frequency selector box to set the center frequency (in Hertz) for the filter
you are configuring. The Range is from 20Hz to 20kHz in 1Hz increments, the default is 1kHz.
` Gain (Available for PEQ filters only): Use the Gain selector box to set the gain value for the filter
you are configuring. The Range is from -15 to 15dB, the default is 0dB.
` Q (Available for Notch and PEQ filters only): Use the Q (Quality Factor) selector box to select the
ratio of the center frequency divided by the bandwidth. Q is the inverse of bandwidth, and the
two parameters are linked. Therefore changing the Q value also changes the bandwidth value.
The Range is from 0.18 to 28.85.
` Bandwidth (Available for Notch and PEQ filters only): Use the Bandwidth selector box to set
the difference between the upper and lower points of a filter’s audio passband. Bandwidth is
the inverse of Q, and the two parameters are linked. Hence changing the bandwidth value also
changes the Q value. The range is 0.05 to 5.00 octaves.
` Bypass: Use the Bypass checkbox to bypass the currently selected active filter. This feature
allows you to configure different filters and save them for future use without having to recreate
them.
° Press the Phase button to display the phase relationship of the graphed frequency response
(appears as a gray line on the active filter graph). The phase scale appears on the right vertical axis
of the graph.
° Click Bypass All to bypass all filters for the selected input channel. The filters are grayed out in
graph view, and the bypass status is shown as on the table view.
° Click Remove Filter to delete the selected filter
° Click Close to apply settings and close the window

There are five configurable filter types available:
All Pass: Frequency range is 20Hz to 20kHz. All pass changes the phase of the audio signal at the set
frequency.
High Pass: Selectable frequency cutoff is 20Hz to 20kHz. Rolloff is 12dB/octave. Level is fixed at 0dB.
Low Pass: Selectable frequency cutoff is 20Hz to 20kHz. Rolloff is 12dB/octave. Level is fixed at 0dB.
Notch: Center frequency range is 20Hz to 20kHz. Bandwidth is from 0.05 to 5.00 octaves in 0.01 octave
increments. Level is fixed at -80dB.
PEQ (Parametric Equalizer): Center Frequency Range is 20Hz to 20kHz in 0.01Hz increments, the
Bandwidth is 0.05 to 5 octaves in 0.01 octave increments, the Level Range is -15 to +15dB in 0.50dB
increments.
