DIGITAL SIGNAL PROCESSOR
Processing Functions Input Filters
Shape
Each DSP is capable of 64 filters that must be shared between Input
Processing Sections. In addition to preprocessing filtering , there is
post-processing filtering and side-chain filtering associated with
each gate. Each individual filter can be switched off or the entire
processing filter section can be turned on or bypassed.
For those who wish to use a more standard Band EQ filter, the
Display function allows a 2 band or 4 band EQ with knobs on.
Low-pass and High-pass shapes can be selected from Butterworth
1-4, Bessel 2-4, or Linkwitz-Riley 4. Shelving filters allow low-
pass or high-pass filtering with adjustable shelf gain.
Equalization filters (Low-pass, High-pass, and Parametric) allow
adjustable gain of the peak and control over the Q of the filter.
Care should be taken when using EQ filters to limit the overall gain.
