Adjusting the Drive

The Drive control, Input control and the vol-

ume of your instrument all interact to create the

distortion sound of the RPM-1. As you turn the

Drive control from fully counter-clockwise

towards the vertical position, you will notice the

sound taking on a warmer or "furry" tone and

the overall volume will increase somewhat. This

may require an adjustment of the Input level.

The exact point at which the distortion starts

depends on the Input level and your instru-

ment's volume. Past the 12 o'clock position, the

distortion becomes more aggressive.

When you play chords at high distortion levels,

you may hear a rhythmic beating sound which

is independent of the horn and rotor speed.

This beating is the interference distortion sound

caused by the interaction between two or more

notes being played at the same time. Try play-

ing single lines instead of chords, and you'll

notice that the beating drops off. If you prefer

not to have this beating sound, reduce the

Use the following settings as a guide to acheiving different effects.

Keep in mind that different instruments may require slightly different

settings, especially in the adjustment of the Drive control.

Performance Notes

Note

The RPM-1 contains a 12AX7A vac-

uum tube, which must be warm

to run properly. Note the air

vents on the front of the case.

Make sure that these

are never blocked, and

ensure that no foreign

object enters these

vents.

Speed control

Organists have traditionally used the speeding

up and slowing down of the rotating speakers

to add emphasis and excitement to their play-

ing. Usually, you would not leave the Fast

Speed setting on continuously, but rather you

would toggle the Fast speed on and off to

emphasize peaks in your playing. The most

interesting part of the rotary speaker sound

occurs while the rotor and horn are accelerating

and decelerating.

Brake

The Brake button will gradually bring the rotary

effect to a complete stop from either the Fast or

the Slow setting. This is useful when you don't

want the rotating effect, but do want the distor-

tion and/or cabinet emulation to warm your

sound up. You can change the Speed setting,

but with the Brake on, there will be no rotating

effect. When you disengage the Brake, the rotor

and horn will then speed up to the current

Speed setting again, based on the Rotor

Acceleration control.

Footswitch

The RPM-1 comes with the DigiTech FS-300

footswitch, which has three switches on it.

From left to right, the footswitches correspond

to the RPM-1's Speed, Brake and Bypass but-

tons.

Using the RPM-1 with Guitar

The RPM-1 faithfully emulates the rotor and

horn resonances of a real cabinet, which can

sound a bit bassy and dark if a guitar is con-

nected directly to the input. It is best to run a

guitar through a pre-amp or a guitar processor

(such as the DigiTech GSP series), with the

RPM-1 in the effects loop, or at the end of the

Balance

audio chain like a real rotating speaker cabinet

would be.

If you want to connect a guitar directly, you

can use the Balance control like a tone control,

more treble on the left (Horn) side, more bass

on the right (Rotor) side.

For a clean, warm sound, keep the volume

control on your guitar and the Input control up
