10.TECHNICAL DESCRIPTION
1. General
The Leslie 2101 system consists of 3 channels: Rotary, Stationary Left and Stationary Right, all of which are
present at the 11-pin input. Each channel is rated at 50 watts. The Rotary channel has other two inputs - a 1/4"
phone jack, and an 8-pin DIN socket for use with Hammond Drawbar Module XM-1. The high frequency
portion of the Rotary channel consists of a spinning horn rotor driven by a DC servo motor, and the low frequency
portion consists of a 2-channel stereo rotary simulator controlled by a DSP (Digital Signal Processor) system.
The DC servo motor is controlled by the CPU, which allows programmable Rotor Speed, Rise Time, Fall Time
and Brake Time. In addition, both the DC servo motor and the DSP bass rotor can respond to incoming MIDI
commands from external MIDI equipment.
The PWBs consist of:
1. PREAMP & PANEL SWITCH PWB (SWH-492A)
2. CPU Control & DSP Effect PWB (EFH-237A)
3. POWER AMP & POWER SUPPLY PWB (PWH-68A)
2. Operation of PWB
A. PREAMP & PANEL SWITCH SWH-492A
This PWB is composed of three parts: PREAMP & FILTER, SWITCH & DISPLAY and JACK.
The signal for the Rotary channel is supplied through pin 1 of the 11-pin connector. Through
J306-1,PHONE JACK JK-5 and JK-8 In input of PIN(1), to The OPAMP U1A and U1B from VR1 after
Mixed U1A make pass a signal from 125Hz to 12KHz in Band Pass Filter and are sent to DSP of
EFH -237A via J301-1. This signal is divided into HF(High Frequency) and LF(Low Frequency) at
approximately 800 Hz of the crossover frequency in the DSP. The HF is, being returned via J301-3 as
the Rotary Horn signal, through BPF circuit U3B, AMP circuit U3A and VR6, and it is supplied to
POWER AMP via J302-1.
The LF signal is changed into the 2-Channel STEREO signa l by Rotary simulator inside DSP. Among
these, the Lch signal returns to J301-9. Then, it is filtered below 1.1KHz by 12dB/oct. Low Pass Filter
in U5A, and the one of this output is sent to LINEOUT JACK.JK3. The other is sent to MIXER U4B.
It is also mixed here with STATIONARY Lch. and the BASS signal, and output is supplied to
PWH-68A POWER AMP via J302-5. Also, the Rch signal returns to J301-7 after that, it is same as
Lch.
On the other hand, only the BASS signal less than 125 Hz is passed by U1B, and it is supplied to U2A,
U2B and U4B, U5B through VR5(ROT BASS ADJUST).
When SLIDE SWITCH SW6 is in Position of STA & BASS MUTE at this time, a becoming BASS
signal is stopped here by Transistor Q5, Q6, Q7 and Q8 which are switched ON.
B. CPU CONTROL & DSP EFFECT EFH-237A
This PWB consists of the MAIN CPU, DSP, ADC, DAC and MEMORY and controls switch functions,
LCD display functions, Motor Control, Leslie simulator, DSP digital filter, etc. The MAIN CPU
program is written in MTP ROM(1M bit) U4. The rotary channel signal sent from J301-1of SWH-492
is converted into digital serial data of 20 bits in AD CONVERTER U10 via J204-1. and is connected to
DSP U9 -PIN(55) & PIN(56) via PIN(15) and U12A. It is filtered, and the DIGITAL EFFECT and
ROTARY EFFECT are added here using the DSP. The 24-bit SERIAL DATA output of the DSP is
sent from AX1(pin 48) and AX2(pin49) to U7(DAC1) and U8(DAC2)PIN(2) and converted back into
an ANALOG signal of 4 channels and applied via J202 and J301 to SWH-492A.

Page 19
#2101/#2102
The voltage of the MOTOR CONTROL is supplied from PIN 85(DAC OUT in CPU) of U1, through R3
to PIN(2) of OPAMP U14A. U14A functions as a DC AMP. The Output Voltage can be adjusted using
TRIM POT VR1. Please refer to TEST & ADJUSTMENT for more information on making
adjustments. This DC voltage is applied to the MOTOR DRIVER PWB via DIODE D2 and J208-5.
C. POWER SUPPLY & POWER AMP PWB PWH-68A
This PWB provides POWER SUPPLY, POWER AMP, POWER ON MUTE RELAY and REMOTE
POWER ON circuit.
POWER SUPPLY:
The Primary coil of POWER TRANS EPH-115 can be changed 100V, 120V, 220-230V or 230-240V by
replacing the VOLTAGE SELECT PLUG. There are three lines of +-34V, +-17.5V, +30V secondary
sides of the transformer. Each three lines apply to the power amplifie r, +-12 V, +5V regulator IC, and
24V for Motor Power supply.
The devices between the transformer volume line and the rectifier diode PSW 1, 2, 3 are POLY
SWITCHes. These devices together perform the same function as a fuse; however, it is not usually
necessary to replace them after a power surge, as they will automatically reset. RXE-185 in this place is
equivalent to a 1.6A timelag or slo -blo fuse.
POWER AMP
The POWER AMP consists of 1-Channel Amp. U1 and 2-Channel Amp U2.
The two outputs from pins 12 and 13 of U1 are mixed at R8 and R9(0.22 ohm) and supplied through
choke coil relay RL1A, and arrive at the Horn Driver via J102-1. RL1A is a muting Relay which
prevents turn-on pop the power is turned “on” or “off.” The operation of U1 and U2 is identical.
The service technician should exercise caution to avoid a short-circuit.
