Operating the RT-20
Operating the BRAKE
You can use the brake to stop the rotation of
the rotor.
Pressing both of the pedals simultaneously
stops the rotation of the rotor.
The SLOW/FAST indicator flashes rapidly
while the brake is on.
The time required for the rotor to come to a
stop after the BRAKE is activated changes
according to the position of the RISE TIME
knob.
The time required for the rotor to stop
increases as the knob is turned further left
from the center position; turning the knob to
the right of the center position decreases the
time required for the rotor to stop.
fig.090
To cancel the BRAKE, pressing either the
light pedal or both left and right pedals
simultaneously.
The rotor always faces directly in front when
stopped.
Controlling the RT-20
with an Expression Pedal
You can connect an optional expression
pedal (such as the Roland EV-5) to the rear
panel SPEED (EXP PEDAL) jack and use the
pedal to control the rotor’s rotation speed in
real time.
fig.100
With the expression pedal fully released, the
RT-20 switches to the value set with the
SLOW SPEED knob; depressing the pedal all
the way switches the RT-20 to the value set
with the FAST SPEED knob.
* The SLOW/FAST indicator flashes when an
expression pedal is connected.
* Operation of the SLOW/FAST pedal is disabled
while the expression pedal is connected.
* You can also use an expression pedal to operate
the BRAKE.
* Use only the specified expression pedal (EV-5;
sold separately). By connecting any other
expression pedals, you risk causing malfunction
and/or damage to the unit.
