Turn on the RPM-1 before your mixer or ampli-
fier, or turn down volume on mixer or amp if
you are going to switch the RPM-1 on or off.

Controls the input level to the RPM-1. Adjust this
while playing so that the Clip indicator only
flashes on the loudest musical peaks. Turning
up the Drive control increases the pre-amp gain,
and you may have to adjust the Input after set-
ting the Drive. (See also page 4 for balancing
Bypass)

(also activated by
the left footswitch
button) Alternates
between the slow
and fast rotary
speeds. The light
will flash in time with the revolutions. 

(also activated by the center footswitch

button) Stops the rotation portion of the effect,
leaving the Drive and Cabinet Emulation effects
in place. The Brake over-rides the speed con-
trol; turn off the Brake to return to the rotating
sound. When the Brake is applied, the Horn
and Rotor stop at a random position, like a real
rotating speaker. By quickly dis-engaging and
re-engaging the Brake, you can change the
stopped position, to control the harmonic con-
tent of the stationary sound.

(also activated by the right footswitch

button) Bypasses the RPM-1 effects so that the
original “dry” signal is sent to all three outputs.
The Bypass is full Stereo - Right and Left
inputs remain separated while the RPM-1 is
Bypassed.  

Controls the amount of overdrive provided by
the RPM-1’s vacuum-tube pre-amp. The tone
will change from clean in the fully counter-
clockwise position, to a lightly compressed
sound with a touch of distortion in the center, to
a compressed, full-out overdrive “crunch” in the
fully clockwise direction. You may have to
adjust the Input after setting the Drive.

Sets the rotation speed of the horn (high fre-
quency portion of the sound) in both the fast
and slow Speed settings.

Because the low-frequency rotor in a rotating
speaker cabinet is much larger than the horn, it
takes longer to speed up and slow down than
the horn does. The Rotor Acceleration control
determines how fast the Rotor sound speeds up
and slows down - clockwise makes the accelera-
tion time shorter. In the fully counter-clockwise
position, the Rotor sound does not turn at all.

Emulates the position of two microphones
around the rotary speaker cabinet. A fully wide
spread setting corresponds to a 180˚ spacing of
the mics (i.e. on either side of the cabinet),
which gives the most dramatic stereo effect. A
fully narrow setting emulates both mics being
placed together giving a monaural sound. If you
are using the RPM-1 with only the mono output,
turn the control fully clockwise. 

Adjusts the volume balance between the high
frequency Horn sound and the low frequency
Rotor sound. This can be used to adjust the fre-
quency balance; counter-clockwise toward Horn
is brighter, clockwise toward Rotor is darker.
