Your new Leslie speaker system contains two rotors to produce the world-renowned “Sound-In-
Motion” effect. The upper frequencies are reproduced by the world-famous Ferro Fluid high-
compression driver and a custom-molded rotary horn. The lower frequencies radiate from the massive
15” woofer and the high-density custom-molded foam drum. The rotors can be operated in
Fast
(Tremolo) or
Slow
(Chorale) modes. Our model 122XB Leslie also features an
Off
mode (rotors
stopped).

The model 122A Leslie is specifically designed for older Hammond
organs such as Hammond organ models A, B, C, and RT, that require
a separate tone cabinet for sound reproduction. The Leslie 122A is
provided with a 6-pin Leslie connector to facilitate easy connection to
these Hammond organ products when used with the proper interface
kit (available at your local Leslie dealer). A Master Volume control,
which is located on the top of the power amplifier, is also provided.
The model 147A Leslie, which shares the same cabinet design as the
Leslie 122A, is recommended for single-channel organs with self-
contained speaker systems, such as Hammond organ model A-100 and
spinet models such as M, M-2, M-3, M-100 and L-100. In addition to
the 6-pin Leslie connector and Master Volume control, the 147A also
contains an Input Selector switch which is located to the left of the
Master Volume control on the top of the power amplifier. This switch
is used to electrically match the impedance of your organ speaker
system. We strongly recommend that a factory-trained technician set
the position of this switch.
The Leslie 122XB is electrically identical to the model 122A, except that it contains an 11-pin Leslie
connector, a ¼” Line Input jack, ¼” foot switch jack and an AC power switch. These features make the
122XB extremely easy to be connected to most keyboard products on the market today. The Leslie
122XB is also designed to interface with newer Hammond organs and keyboards like the New B-3,
Traditional and Pro XK Systems, and our XK-3 keyboard, that contain an 11-pin Leslie connector.
