Steep Resonant Bass:
Resonance
This function uses a two-pole lowpass Þlter to give you a sharper transition in bass response
than PARA BASS. Like PARA BASS, there are control inputs pages for cutoff frequency and
amplitude, which are identical to those for PARA BASS. There is also a control input page for
resonance (also known as ÒqÓ), which can boost or cut the amplitude of the partials near the
cutoff frequency.

YouÕll get the best transition in bass response with a resonance setting of -6 dB. ThereÕs a small
frequency range above the cutoff frequency where the response reverses direction (if youÕre
cutting the amplitude, for example, youÕll get a slight boost just above the cutoff frequency).
The higher you set the resonance, the larger this reversal will be, resulting in unusualÑbut
possibly usefulÑresponse curves at high resonance values.
