By default, Band 1 is a shelf when it is boosted (gain > 0 dB) and a high pass when it is cut (gain < 0
dB). By default, Band 4 is a shelf when it is boosted (gain > 0 dB) and a low pass when it is cut (gain <
0 dB). Using the Neuro App, Bands 1 and 4 can optionally be configured as a shelves when cutting
(gain < 0 dB), with optional values for slope and rolloff.
The left channel and right channel can each have unique boost/cut values for each of the 4 bands.
However, the filter types and cutoff frequencies (or center frequencies) must be the same for both
channels.
The physical BASS KNOB and TREBLE KNOB directly control the boost or cut of the parametric EQ’s bass
and treble bands.
Low Cut Filter
The Kingmaker also includes two low cut filters (a.k.a. high pass filter) with an adjustable frequency.
This filter is very useful for cutting out low frequencies that do not contribute to the sound of the
instrument, as well as subsonic frequencies which cannot be heard at all. Bass players often use low
cut filters set very low (around 10 Hz to 30 Hz) to reduce speaker excursion and improve the clarity of
the bass. Guitarists often use low cut filters set somewhat higher (around 80 Hz) in order to give the
bass player additional room in the low end of the mix.
The Parametric EQ and the Low Cut filter are configurable using the Neuro App. By default, the
parametric EQ is disabled (flat), and the Low Cut filter is set to 10 Hz.
LoRetain
LoRetain is a technique used by Source Audio to maintain a solid low end even with high amounts of
distortion. This is particularly useful for bass players or extended-scale guitar players (7-string and 8-
