Parameters
While the Multimode EQ has many parameters applicable to the various possible
configurations of channels and filters, it selectively enables or hides parameters
depending on their applicability to the current configuration. As a result, not all of the
parameters listed below appear on-screen at the same time.
Parameter Description
Filter Edit This parameter controls whether the filter editing parameters apply
to both left and right channels in tandem (Stereo), only to the left
channel (Left) or only to the right channel (Right).
Filter Mode This parameter selects one of 5 different filter types: Lowpass,
Highpass, Lowpass+Highpass, Band Pass or Band Cut.
Lowpass
The frequency response of the lowpass filter looks something like the diagram below:
In this mode, the Lowpass filter can have up to a 48dB/octave rolloff slope. In this
mode the Lowpass Rolloff, Lowpass Frequency and Lowpass Resonance parameters are
available for editing the filter response.
Highpass
The frequency response of the highpass filter looks something like the diagram below:
In this mode, the Highpass filter can have up to a 48dB/octave rolloff slope. The
Highpass Rolloff, Highpass Frequency and Highpass Resonance parameters are
available for editing the filter response.
