1) MAINS INPuT:
Plug the supplied IEC cord into the outlet to supply power to the unit.
2) MAINS FuSE:
Units equipped for 120VAC mains: 3A Slow Blow 5x20mm
Units equipped for 240VAC mains: 1.5A Slow Blow 5x20mm
*Units equipped for 240VAC must only be used with Leslie™ ampliers and motors that
are outtted for 240VAC mains usage.
3) POwER SwITCh:
Turns the L.T.P. on and off.
Always make sure that all cable connections have been made before
turning the unit on.
4) INPuT JACk:
Plug in the 1/4” output of the instrument of your choice: Guitar, Electric
Piano, Keyboard, Etc.
5) PREAMP OuTPuT JACk:
Take the output signal of the preamp via a 1/4” cable and interface it with
a mixing console, powered speakers, power amp, F.O.H., etc.
6) PREAMP TRIM POT:
Use a small screwdriver to set the level of the signal found at the
Preamp Output Jack. Always begin with the trimmer turned fully counter
clockwise and then turn it up to the desired level for the gear you are
interfacing with.

7) PreamP OutPut GrOund Lift Switch:
Lifts the ground connection at the Preamp Output Jack.
If you detect hum or buzz when interfacing the 1/4” preamp output with
another piece of gear, pushing the ground lift will remove the L.T.P.’s
ground from that signal path and eliminate a potential ground loop.
8) 6 Pin amPhenOL SOcketS:
Plug your standard 6 Pin Leslie™ cable between the L.T.P. and the
appropriate Leslie™ unit.
The 122 socket should only be interfaced with 122 type Leslie™ units.
The 147 socket should only be interfaced with 147 type Leslie™ units.
*When utlizing the L.T.P. with a model 147 Leslie™, ensure that the load
switch on the Leslie™ amplier is set to open.
**Interfacing one of the sockets with a non-corresponding Leslie™ unit
could result in damage to the L.T.P. and Leslie™ and is considered
misuse and not covered by any warranty**
frOnt PaneL cOnnectiOnS & indicatOrS
1) VOLume cOntrOL:
Adjusts the overall gain / level of the preamplier
2) trebLe cOntrOL:
Adjusts the higher frequency content of the signal

3) Bass Control:
Adjusts the lower frequency content of the signal
When adjusting the tone and volume controls, consider the gain staging
between the L.T.P. and the Leslie™ amplier. Think of the volume
control on the Leslie™ amplier as the Master Volume.
For clean tones, set the volume control on the Leslie™ amplier to the
fully clockwise position and adjust the L.T.P. controls to taste.
For dirtier tones, set the L.T.P. controls to taste and use the volume
control on the Leslie™ amplier to adjust your overall volume.
1) speed FootswitCh:
Changes the speed of the Leslie rotors between Chorale and Tremolo.
When the Chorale speed is selected, the Blue indicator light will be
illuminated.
When the Tremolo speed is selected, the Red indicator light will be
illuminated.
2) Mute FootswitCh:
When engaged, the Leslie™ amplier will be muted but the preamplier
signal will still be present at the Preamp Output Jack. This is useful to
those users who wish to feature the Leslie™ tone as an effect during
certain passages while still maintaining the signal from the preamp to a
power amp, mixing console, F.O.H., etc.
