From the manufacturer:

This unit is a line level rack mount signal processor for duplicating the sound of a rotating horn speaker cabinet electronically. It has a two-way crossover network to produce the effect of bass and treble "rotors". The unit is housed in a single space 19" rack painted steel chassis and is intended for live performance or studio work. The RFX147 is simple to use and is ready to work on power up. 

FEATURES • Accurate simulation of "Leslie" fast and slow speeds • Front panel and footswitch (not included) control of all functions • Smooth sounding CHORUS effect • Mono VIBRATO effect
