The Leslie 525 / 3301 stationary speaker systems have been designed to enhance and amplify the sound of
most keyboard products on the market today. It can also be used to add an additional channel to any Leslie
speaker to facilitate multi-channel organs. These Leslies feature a 300-watt RMS solid-state single-channel
amplifier. Its five-speaker system produces extremely clean highs and solid deep bass that you can actually
feel! To make it easy to connect to most keyboard or electronic organs, we have provided an 11-pin Leslie
connector and a ¼” line input jack on the rear panel. Master volume, bass and treble controls are provided so
that you can adjust the sound to match your room acoustics.
Product Overview
The Leslie 525, in its furniture-grade cabinet, was designed
to be placed directly on top of any traditional Leslie speaker
such as our 122XB or our 971 for multi-channel installations
or in any remote position. The Leslie 3301 with its rugged
cabinet was designed to be placed directly on the floor when
used to amplify a keyboard-type product. In the case when
you need to add an additional channel to our portable Leslie
3300, this cosmetically matching unit can be placed directly
on top of the Leslie 3300. If you desire true stereo separation
in your musical performance, use two Leslie 525s or 3301s.
