The RPM-1 is equipped with a three-prong,

grounded power cord for your protection. Do

not cut off the ground prong of the plug, and

do not use an adapter or extension cord to plug

the unit into a two prong outlet unless the

adapter or extension cord is properly grounded.

The RPM-1, like any piece of music hardware, is

sensitive to voltage drops, spikes, and surges;

interference such as lightning or power

"brownouts" can permanently damage the cir-

cuitry inside the unit. Here are some suggestions

to help protect your RPM-1 from such a fate:

• Turn it off: Make a habit of turning off all of

your gear when it is not in use. If there is

lightning or a severe windstorm, unplug all of

your equipment: A surge from a nearby light-

ning strike or downed power line can destroy

electronic equipment even if the switch is off.

Thank you for purchasing the DigiTech RPM-1,

a new effect that creates a classic sound.

When electric organs were first sold, their

sound was static and needed some "animation",

so the rotating speaker cabinet was born. The

rotating speaker sound became synonymous

with blues, jazz and rock & roll, especially

when players discovered that they could drive

the cabinets' built-in tube amplifiers into distor-

tion and get a thick, warm sound as well as the

swirling rotary effect. (See diagram, page 6)

The DigiTech RPM-1 allows you to emulate that

classic rotating speaker sound without having to

deal with the bulky speaker cabinets that were

formerly required.

Based on extensive study of rotating speaker

cabinets, the DigiTech RPM-1 incorporates

speaker emulation circuitry which delivers an

authentic sound by recreating the individual

horn and cabinet resonances of a real rotating

speaker.

Power and Grounding

Information:

• Spike/Surge Protectors: This is an inexpensive

solution to all but the severest of AC line

conditions. Surge protected power strips are

usually slightly more expensive than unpro-

tected strips, and higher quality multi-stage

surge suppressors usually start under $50,

making them a worthwhile investment for

protection of all your valuable electronic

equipment.

• AC Line Conditioners: This is the best (but

most expensive) way to protect your musical

equipment from line voltage fluctuations. Line

conditioners constantly monitor the incoming

voltage for excessive peaks and dips and

make adjustments accordingly, delivering

consistent power levels. For expensive studio

equipment, AC line conditioners are highly

recommended.

Introduction:

There are several features of the DigiTech

RPM–1 that make it unique:

1) Where competing products use solid-state

distortion circuitry to simulate overdriven

sounds, the DigiTech RPM-1 is unique in that it

uses a vacuum tube analog distortion pre-amp.

The 12AX7A pre-amp stage gives you the

authentic, rich, warm overdriven sounds previ-

ously attainable only with actual rotating speak-

er cabinets.

2) Only the DigiTech RPM-1 gives you the flexi-

bility to run mono, stereo, or tri-output mode to

simulate the most effective microphone arrange-

ments on stage or in the studio.

3) The DigiTech RPM-1 is a ruggedly built, 1U

full rack-mount unit, with AC power. No exter-

nal power supplies or flimsy plastic cases.

4) While other units are based on modified cho-

rus or phase-shifting circuits, only the DigiTech

RPM-1 incorporates patented Intelligent Pitch

Shifting technology together with VLSI delay

and volume modulation circuitry for maximum

realism.
