Technical information

McDSP plug-ins
The E606 has a high-pass  lter and a low-pass  lter, each with a Freq control
to set the cuto frequency below or above which signals will be attenuated by
the  lter and a button that can be used to select the rate at which the signal
level drops. There are two choices provided here: either a 6 dB/octave or a
12dB/octave  lter slope.
The E606 also has a low-shelf EQ and a high-shelf EQ, each with controls
for Gain (i.e. the amount of signal level increase or decrease at the selected
frequency) and Frequency. Three numerical data entry fields are provided
for each shelving  lter to allow settings to be entered for Peak, Slope, and
Dip. Peak is the amount of overshoot, or ‘peak’, in the shelf portion of the EQ
response; Slope is the rate of transition, or ‘slope’ of the EQ shelf; and Dip is the
amount of undershoot, or ‘dip’, in the shelf portion of the EQ response.
These Peak, Slope, and Dip controls allow you to adjust the overshoot or peak
in a shelf band, or to adjust the undershoot or dip in a non-shelf band, or to
adjust the slope or transition between the shelved and non-shelved part –
providing a great deal of  exibility compared with  xed designs.
Two parametric EQ filters are also provided, each with controls for Gain,
Frequency, and Q – the width of the band of frequencies that will be attenuated
or boosted by the  lter.
