Balance
The Balance knob adjusts the relative volumes of the bass and
treble speakers. Use it much like you would an equalizer,
adapting the unit's sound to suit different types of input signals
and the musical context, amp, or monitor.
Twisting it to the right from the 12 o'clock position cuts low
frequencies; turning it to the left cuts higher frequencies.
Drive
This knob activates VENTILATOR's on-board tube simulator.
To make the most of the Drive section, ensure you dial in the
optimum input level as described in the section above entitled
Overload LED. Then set the organ's volume pedal to the
maximum level and twist VENTILATOR's Drive knob to dial in
the maximum distortion level. This lets you ride the organ's
volume pedal to control the amount of saturation, which is a
convenient and musically expressive way of modulating
between clean and distorted sounds the fly.
The Drive section is level-compensated; that is, the output level
does not change as you turn up the Drive knob.
Distance
The Distance parameter determines how far away from the
Leslie the virtual microphones are placed. The further you twist
the knob clockwise, the greater the distance.
Turning the knob to the far left adds lots of amplitude
modulation so the result sounds like a close mic'ed Leslie on
stage. Twisting the Distance knob to the right conjures more
diffuse sounds with less amplitude modulation, replicating a
studio setup with the mics placed a meter or two away.
