Installing two 525 or 3301 Leslies with ¼” audio cable assemblies
4. Plug one end of the optional audio cable into the left Line Output jack. Plug the other end of the audio
cable into the Leslie 525 or 3301 Line Input jack that will be used for the left-channel audio. Repeat the
above procedure for the right-channel Leslie speaker.
5. Plug the AC power cords from the Leslies into a 120V AC outlet.
6. Turn the Master volume controls on the Leslies (see page 3) to the fully counterclockwise position. Set
the bass and treble controls to the mid-position.
7. If you are connecting a Hammond organ to your Leslie, pull all the upper and lower drawbars including
the pedal drawbar fully out (#9 positions). Set the expression pedal to the loudest position (fully
depressed). For non-Hammond products, set the volume control to the loudest position and set the voice
registration to a setting that provides maximum sound (i.e. Full organ).
8. Turn on the power switch on your organ or keyboard product.. For organs, play a three-note chord on the
upper and lower manuals and depress the low “C” pedal. For keyboards, place the unit in the split
keyboard mode and play a three-note chord on the upper manual and the low ”C” pedal note. Have
someone slowly turn the volume control clockwise on one of the Leslies until the sound begins to distort,
then slowly decrease the volume (turn the control counterclockwise) until the sound is undistorted. Your
volume control is now properly set. Repeat this procedure for the other Leslie speaker.
Caution: Do not play your Leslie at a volume setting that produces a distorted sound. Severe damage
may occur to your new Leslie if played in this condition for an extended period of time.
