Now, there are several
Multi-Channel, High-Power Leslie Model Choices
The Hammond organ and Leslie speaker are synonymous with classic Rock, Blues, Jazz ,
Gospel, Country and other music styles. However, virtually all new organs among many
manufacturers are equipped with multiple channels and require a multi-channel Leslie to
adequately reproduce the many channels. Some applications such as live-stage performances
and large church organ installations may require one or more high power Leslie’s, possibly
used in conjunction with single-channel tube models (122, 147), the solid-state model 771,
or with other external high power sound systems.
Designed for New Multi-Channel Hammond Organs
Each high-power, multi-channel Leslie speaker was designed to complement the latest
Digital technology advancements in organ design. Two, Three and Four-Channel Leslie models
are available in several cabinetry finish options. Each of the multi-channel Leslie
speakers comes equipped with an 11-pin connector, and Leslie connector kits are available
to connect these Leslie’s to virtually any other organ manufacturer’s products.
Excellent for use with MIDI Sound Modules or
MIDI-equipped Keyboards
Several of the new multi-channel Leslie’s will also directly accommodate the Hammond
GM-1000 MIDI Sound Module when used in conjunction with a new Hammond organ. Older organs
models including Tonewheel Generator Organs (B-3, C-3, A-100, etc.) can be easily
connected to the new 11-pin Leslie models through a custom Leslie Connector Kit. The
Hammond XB-2 Keyboard and XB-5 Pro-Portable organ also are directly “plug-in”
compatible into any 11-pin model Leslie.
Additional information on Leslie Connector Kits can be found elsewhere in our ON-LINE
Catalog of parts, equipment and services.
