Core Effects Descriptions
Multimode EQ
The Multimode EQ is a flexible stereo filter that is capable of implementing a range of
powerful filter topologies. It is useful both for utility EQ applications and also for
special effects.
The Multimode EQ is built from an array of filter sections that can be configured to
support:
• Lowpass filters with up to 48dB/octave rolloff
• Highpass filters with up to 48dB/octave rolloff
• Highpass + Lowpass series or parallel combination with up to
24dB/octave rolloff
• Bandpass filters with up to 24dB/octave rolloff
• Bandcut filters with up to 24dB/octave rolloff
In addition to cutoff or center frequency parameters, each of the above filter types also
has a switchable rolloff rate and adjustable resonance.
A Filter Edit parameter controls whether the Multimode EQ operates in Stereo, where
filter parameters are adjusted identically for both channels, or split Left and Right,
where the left and right channels support completely independent filter types and
parameter values.
In addition to a standard Bypass switch, the effect offers an adjustable wet/dry mix
parameter. While not normally found on EQ sections, adjustable wet/dry mixtures can
be useful for generating phase cancellation and other special effects.
Applications
• Basic Tone Control - for fidelity enhancement
• Rumble Filter - use the highpass configuration with 48dB/octave rolloff below
50Hz.
• Subwoofer Support - use the lowpass configuration with 48dB/octave rolloff
below 100Hz.
• Lo-Fi Effect (telephone, walkie-talkie, guitar mini-amp, distance simulation)
• Extreme Spectral Shaping - use Highpass+Lowpass, Bandpass or Bandcut with
independent hi/lo resonance
• Pseudo-stereo Effect - apply slightly different EQ to left and right channels to
broaden the spread of a mono signal
• Cross-over - left and right channels split a mono signal between highpass and
lowpass with a sharp transition region.
