The UC-1A allows most Leslie speakers to be used with a portable organ, guitar, synthesizer, or any audio source that can be fed into a standard 1/4" plug. The UC-1A is equipped with four different outlets, one to accommodate each of the Leslie families listed below.
These four outlets may be used singularly or in any combination.
(Yes, if you happen to have a Leslie from each of the four groups, you really could play them all simultaneously with the UC-1A!)
• Foot switch tremolo control
• Foot switch power on / off
• Power and tremolo indicators
• Input level and tone controls
