OWNERS MANUAL
INTRODUCTION
Thank you for y our purchase of the Rolls RP147 Rotorhorn. The RP147 is a line
level r ac k mount signal processor f or duplicating the sound of a rotating horn
speaker cabinet electronically. It has two-way crossov er network as well as
simulated bass and treble “rotors”. It may be controlled by the front panel, remote
foot switch or MIDI prog ram changes and is housed in a single space 19" painted
steel chassis. the RP147 is intended f or liv e performance or studio work, it is
simple to use and is ready to work upon power up.
Features
> Accurate simulation of “Leslie” fast, slow, and brake
> Front panel and f oots witch control of all functions
> MIDI control of all functions
> Single space 19" rack chassis
> Both chorus and vibrato modes
> Will phantom power all R OLLS MIDI f oot controllers
> Speed may be controlled by controller #4
Using the ROLLS RP147
Connect the signal source to the input jacks on the rear. If a mono source is used use only
“RIGHT IN” and “RIGHT OUT”. The eff ect will come out both jacks but in “BYPASS” only the
inputs connected will pass through. The “INPUT LEVEL” may be used to match the b ypass
signal or make the process signal greater or less. If too much signal is input the special
overdrive circuits offer a “tube” like distortion. The unit may be controlled three ways, front
panel buttons, remote foot switch, and MIDI controller.
If MIDI control is being used connect the controller to the MIDI IN jack on the rear
panel. If a ROLLS MIDI controller is used a power adapter will not be necessary as the
power will be through the cable (as long as the cable has all 5 wires connected). The
RP147 recognizes program change numbers 1 through 5 as follows.
Program change # (numbers starting at 1)
1 > Bypass
2 > Active (nothing changed)
3 > Active slow
4 > Active fast
5 > Active stop
The speed may be controlled by controller #4 on the same channel as the program changes. The speed will vary with data #127 being equivalent to the fast speed and
data #0 as stop. If your controller doesn’t have that much range you can still achieve full
speed range by adjusting P2 on the circuit board to full CCW, this will give the maximum
range the controller can give but when it is being used with the other controls the f ast speed
will be too fast. Also touching an y b utton or sending a progr am change will tak e it out of the
“controller” mode and the RP147 will assume the new parameter, a new controller data #
will have to be sent to resume operation. Adjusting P2 is cause for deep meditation and
soul searching.

On the rear panel is a 3 pin header connector that is used for selecting the MIDI
channel, only channel 1, 9 or 16 may be selected. The unit must be off when changing the
channel, looking at the rear the pins are numbered 3 2 1. With no shorting clip the RP147 is
in “omni” mode, or all channels are recognized.
No pins shorted = all channels recognized
Pins 1 and 2 shorted = channel 9
Pins 3 and 2 shorted = channel 1
Pins 1, 2 and 3 shorted = channel 16
The ROLLS RP8 dual foot s witch ma y be used to control the RP147 by connecting a stereo
cord between the two. This will allow fast/slow and active/bypass control. And it is theoretically possible to enter “BRAKE” if both are pressed exactly together.
The speeds are controlled internally by trim pots located on the motherboard. P2 controls
the fast speed and P3 the slow.
