The Spin-Tone 400 incorporates a hybrid system with a rotating horn at the top and powerful woofers at the bottom specially designed to recreate the original rotating speakers. It is equipped with 3 amplified channels with a horn driver and 2 woofers coupled, however, to 2 tweeters, as the device can also be used as a normal static amplifier to be connected to any type of musical instrument.
 
The rear panel gathers the main controls for quick configuration of the loudspeaker, such as adjusting the equaliser, volumes, selecting one of 6 operating presets and timbre response, and the connection connectors. Slow/Fast or stop speeds are selectable via the lever control on your Legend or Legend Soul connected to the 11-pin connector, or via a footswitch pedal or MIDI.
 
Also available on the site is the Rotary Editor application, compatible with Windows, macOS, and iOS, which allows fine-tuning of the most important setup parameters and software updates of Spin-Tone.
