achieved by unplugging the motors on the lower rotor, so that
only the upper rotor spins.
From center to 5 o’clock (all the way clockwise), the knob
adjusts the distance of the virtual mic from the lower rotor. This
is handy for decreasing the amount of AM (amplitude
modulation) in the signal. Pulling the mic further back
decreases the “wub wub wub” effect that can be distracting,
especially when you’re playing left hand and/or pedal bass.
MIX / DIST HI
As with the MIX / DIST LO knob, this controls the mix of the
upper rotor in the signal as well as the distance of the virtual
mics from the rotor. The first half of the travel (from all the way
counter-clockwise to center) determines the mix. At 7 o’clock
(all the way counter-clockwise) there is no upper rotor
simulation in the mix. Instead you’ll hear the direct input signal
(in stereo if both jacks are used).
From center to 5 o’clock (all the way clockwise), the knob
adjusts the distance of the virtual mics from the upper rotor.
III.2.2 Pots Secondary Functions
SLOW SPEED
The Slow Speed knob adjusts the bass and treble rotors’
speeds while the unit is in SLOW mode. Twist the knob to the
far left for slower speeds and to the far right for faster speeds:
SLOW
Bass 0,12Hz – 2,51Hz (0,76Hz)
Horn 0,13Hz – 2,62Hz (0,8Hz)
