Cheap solid state components and the need for more portable equipment led to the development of numerous "electronic Leslies" and tremolo-vibrato add-on devices. Few early Leslie simulators were authentic enough to fool even causal listeners and rarely sounded like a real Leslie Speaker. Most relied on simple phase-shift circuitry and their primary advantages were compactness and low cost. Current equipment is much improved and it's often difficult to tell the difference between a real Leslie and a simulator, especially on recordings. All mechanical rotary tremolo systems are based on the Doppler-effect. Discovered by Austrian mathematician and physicist Christian Doppler (1803-1853) in the early nineteenth century, the Doppler-effect is the apparent variation in pitch that a stationary listener hears from a moving sound source. In practice, the loudness of the sound also appears to vary and it is this combination of frequency (vibrato) and ampli-tude (tremolo) modulation that give rotating speaker and other Doppler-effect systems their characteristic sound. However, most simulators don't reflect sound or produce the unique audio characteristics of mechanical systems. Rotating speaker elements also direct sound out the sides and back of the cabinet which is reflected off nearby walls and surfaces. The listener hears this combination of primary and reflected sound as a moving audio field. Even when the audio source (organ) is mono, the rotating speaker elements and reflected sound create a realistic stereo effect. The RFX147 Rotorhorn simulates the Leslie speaker effect unlike any other electronic simulator by utilizing an internal crossover. This provides a way to effect the upper and lower frequencies differently much like a real rotating speaker. A more authentic effect is thus produced. 2 3 4 5 6 BACK COVER 1 6 SCHEMATIC Title: RFX147 ROTATING SPEAKER SIMULATOR Sheet 1 of 1 Rev: DESCRIPTION FRONT PANEL ROLLS CORPORATION 5968 South 350 West 84107 Salt Lake City, UT R61 1K Q4 2N4124 1458 Document Number: 10K R60 10K R74 4 . 7 K 7 R59 -12V R54 22K U13A 11 9 R .
