Ë A Brief History of the Leslie Speaker
The Leslie Speaker was first developed in the late 1930's by Donald J. Leslie as a way to improve the sound of then-current Hammond Organs. Mr. Leslie found that rotating a baffle in front of a stationary speaker added a very pleasing “tremolo-type” sound to organ music. This technique is a musical application of the “Doppler effect,” which is the apparent variation in pitch that a stationary listener hears from a moving sound source. The loudness of the sound also appears to vary, and it is this combination of frequency (vibrato) and amplitude (tremolo) modulation that give Leslie Speakers their characteristic sound.
In the majority of Leslie Speakers, there are actually two rotating baffles and two speakers. One speaker handles the high frequencies and is mounted in the upper part of the cabinet. The baffle and motor for this speaker are collectively called the Horn Rotor. The other larger speaker reproduces the bass or pedal frequencies and uses a larger baffle, and is therefore called the Bass or Low Rotor.
In addition to rotating a baffle at a high rate of speed to produce Tremolo, it is also possible to create a pleasing “Chorale “ or “celeste” effect by rotating the baffle at a slow rate of speed - hence the rotor speed designations of Fast and Slow. The Chorale or effect is similar the effect produced by two ranks of pipes being slightly out of tune with each other and being played simultaneously on a pipe organ.
Ë Why Leslie Speed Controls?
For many years, Leslie Speakers only had one speed - Fast or Tremolo. Even after the Chorale speed was introduced in the mid ‘60's. variations in the basic speed were introduced by relocating the motor drive belt to a different pulley to make the baffles turn either faster or slower. Although each Leslie Speaker cabinet was and is carefully calibrated at the factory, several factors such as motor age and placement of the belts on the pulleys can affect the speeds of the rotors as well as the time required for the rotors to speed up (Rise Time), slow down (Fall Time) or come to a complete stop (Brake Time).
Your new Leslie Speaker features a new brushless DC-controlled motor for the Horn and a newly-designed digital Low rotor which allows control of these parameters to an unprecedented degree. You can now “customize” your Leslie Speaker to produce exactly the characteristics you want.

External Speaker System(LPS-21)
The Leslie® model 2101mk2 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.

STATIONARY Input Select
STEREO : L and R input are output in stereo.
MONO : L and R input are summed into mono.
LINE OUT JACK
Each LINE OUT JACK is Stereo Jack.
The maximum effect is achieved by using "Y" cable of the stereo.
Please let me output only "L" signal by using the mono-cable for the thing.
STATIONARY & BASS (L/MONO, R) : Allows both the STATIONARY and the LOW ROTARY channels
to be connected to an external amplifier. To connect the STATIONARY UNIT (Optional) Companion Leslie Model #2121 Stationary Amplifier, connect the L/MONO OUT to INPUT 2 on the Leslie Model #2121.
ROTARY (L/MONO, R) : Allows the LOW ROTARY channel to be connected to an external amplifier.
To connect the STATIONARY UNIT (Optional) companion Leslie Model #2121 Stationary Amplifier, connect the L/MONO OUT to INPUT 3.
NOTE: The HORN ROTOR channel has no LINE OUT connection due to the acoustic nature of the sound produced. Using the HORN Rotary channel with external amplification requires a microphone.
AC Inlet
Plug the female end of a grounded AC power cord into this receptacle, and the male end into an AC outlet.
CAUTION
This unit shall be connected to a MAINS socket outlet with a protective earth connection.
REMOTE
When the Leslie 2121 Stationary-Unit is connected, connect to the REMOTE IN with a DCC-2 cable. The power for the Stationary-Unit can be turned “ON” and “OFF” by the power switch of the Horn-Unit.
Power Switch ON / OFF
This allows the Leslie Speaker to be turned “ON” or “OFF”. When the 11PIN Leslie Cable is connected.
set the Power switch to the "Off" position. When the attached Hammond Organ is switched "on", the Leslie 21 system will also power on.
CAUTION
Even when the POWER switch is turned off, electricity is still flowing to the instrument at the minimum level. When you are not using the instrument for a long time,make sure you unplug the power cord from the wall AC outlet.
FOOT SW
PRESET : Allows switch alternate between PRESET 1 and 2 using a latching-type Foot Switch.
SLOW/FAST/STOP : Allows you to control the speed of the Leslie rotors using the optional FS-9H Foot Switch. Each time the Foot Switch is activated, the rotors will switch between SLOW and FAST. If the Foot Switch is pressed and held for more than 1 second, the Rotors will Stop.
