Product Overview - Leslie 971 Owner's Manual

Product Overview

The Leslie 971 speaker system is designed for the musician who demands the full-spectrum sound. This
single-channel Leslie contains two rotors to produce the world-renowned "Sound-In-Motion" effect. The upper
frequencies are reproduced by the world-famous Ferro Fluid high-compression driver and a custom-molded
rotary horn. The lower frequencies radiate from the massive 15" woofer and the high-density custom-molded
foam drum. The rotors can be operated in three different modes: Slow (Chorale), Fast (Tremolo), or Off. This
Leslie is powered by a new 300-Watt RMS solid-state amplifier which produces outstanding sound fidelity at a
volume that can be heard clearly at rock concerts or church services. The rugged electronics provide long life,
reliability and power for professional and institutional applications.
Your new Leslie 971 has been provided with an 11-pin
Leslie connector and a ¼" Line Input jack. This gives you
the flexibility to connect your Leslie to most new Hammond
organ and keyboard products on the market today. A ¼" foot
switch jack has also been provided so that you can control
the speeds of the Leslie. Our model FS-10TL foot switch has
been especially designed to interface with your new Leslie.
It contains two foot switches that together will provide three
different modes of operation: Slow, Fast, and Off. Your new
Leslie also contains a Line Output jack that can be used to
drive most powered subwoofers. Master volume and horn
and bass level controls are provided so that you can adjust
the sound to match your room acoustics.
