![]() ![]() ![]() Unlike most popular music amplifiers, Leslie speakers use an amphenol connection to interface directly with an organ. Learning how to effectively use this spinning to emphasize a new song section or add a different color is the key. Great expressive effects can be achieved by manipulating the speeds of the speakers. At the chorale or slow setting there is a gentle swirl to the sound. The audio emitted by the Leslie Speaker has a chorused wind driven sound when the speakers are switched to fast. The top horn also has a visible belt that can be placed on 3 different "gears" for a slightly different spin effect. Once amplified, the signal travels to an audio crossover which splits the sound into separate frequency bands that can be individually routed to each loudspeaker The high frequencies to the horn on top and the bass frequencies to the bass woofer. The audio signal enters the amplifier from an instrument (The green box at the lower left of the image). What we call a Leslie speaker is actually a number of individual components housed in a usually large wood casing. This is a diagram of the inside of a Leslie Speaker.
