WHAT IS THE LESLIE EFFECT?
The Leslie Speaker was invented by Donald Leslie in
1941 to make the Hammond Organ sound like a Thea-
tre Pipe Organ. Using motor-driven rotating horns and
ba es, Leslie’s invention gave the organ a rich and
moving tone, which quickly became it’s own unforget-
table sound.
In its basic form, the Leslie Speaker has an built-in
ampli er and two rotors; the “Horn Rotor” for treble
and the “Bass Rotor” for bass which are each fed by a
custom-designed driver/speaker. The combination of
the two utilizes the “Doppler E ect” to give the unique
Leslie “swirling” sound.
Some models have not only rotors but also a  xed
speaker. The circuit for sending the sound to the rotor
is called the “Rotary Channel”, and that for the  xed
speaker is called the “Stationary Channel”.
The Digital Leslie on-board the XK-1C employs all the
proprietary concepts used in the physical speakers, but
realizes them in the digital realm. It is recommended
that you run the Main Outputs “in stereo” to get the full-
est e ect.
