to insure
your
enjoyment
of
performing
music.
The Leslie®models 2101, 2102 and 2103 contain
two rotors to produce the world-renowned Leslie
Speaker "Sound-In-Motion®." The sound is
"separated" with the highs reproduced by a horn
rotor and the lows reproduced by a two 5" speakers
with electronic rotor capability. Both the
mechanical and electronic rotors can be operated in
two modes - Fast (Tremolo) or Slow (Chorale).
In addition, there is a stationary channel designed to
accommodate the audio signal from another sound
source such as a synthesizer or external sound
module. This audio signal is handled by three
speakers - the two 13cm speakers which also handle
the lower frequencies for the rotary channel, and
two 5cm dome tweeters for the high frequencies.
The Model 2101 cabinet comes in a textured black
finish with side handles for professional portability,
the Model 2102 cabinet is finished in silver and the
Model 2103 is finished in a rich Walnut.

making the
connections
ËConnecting to a single-channel Hammond Organ using the 11-pin receptacle
The above example show a Hammond XK-2 connected to a Leslie Horn Unit. The audio signal is
connected via an 11-pin Leslie Cable.
To make this hookup:
1. Make sure the power to both units is “OFF.”
2. Set the STATIONARY Volume Controls on the Leslie Speaker to “0" or Off to reduce
noise, since the XK-2 uses the Rotary channel only.
3. Set the ROTARY Volume Control to a low setting
(the 10 o’clock position is recommended) when first making the connection.
4. Plug the female end of the Leslie Connector Cable into the receptacle on the back of the
Leslie Speaker.
5. Plug the male end of the Connector Cable into the 11-pin Leslie socket of the organ.
6. Turn the organ “ON.” After about 5 seconds, the Leslie Speaker will turn “ON.” Then
adjust the volume settings of both units to your liking.
NOTE: In addition, a MIDI cable can be connected from the MIDI OUT of the XK-2 to the MIDI IN of the Leslie
to allow the XK-2 to control the Advanced Features of the Leslie. Please see page 28 for more information.
NOTE: The above hookup will also work with older Hammond products such as XB-2, XB-5 and XB-3;
however, all MIDI features may not be available. Please see page 27 for more information.
