Viscount Vortex 315
Vortex 315 is a 2 amplified channel rotary speaker composed by a woofer with rotating drum and a driver with rotating horn, specifically designed by Silvio Della Mattia, to reproduce the original rotary horn speakers.
This system of sound amplification and diffusion became popular with the advent of the electromechanical organ and consisted of two sections, one dedicated to high tones (horn) and another concerning low tones (drum), which could rotate at different speeds and produce a particular three-dimensional effect due to the rotation of the loudspeakers. This effect is the result of the Doppler effect, due to the relative displacement of the sound sources with respect to the listener, and the sound reflections resulting from the rotation.
The front panel gathers the main controls for quick speaker set-up, such as choosing the stop position (Brake), adjusting the horn rotation speed, EQ, volume, selecting one of the 6 tone response presets, and the connection connectors.
Slow/Fast rotation speeds or Brake are selectable via the lever control of your Legend or Legend Soul connected to the 11-pin connector, or via a foot-switch pedal or MIDI.
Also available for free download is the Windows and Mac OS (also iOS) compatible Vortex Editor application, which allows fine tuning of the most important configuration parameters.
Vortex 315 is the perfect speaker to connect to your Legend Soul, or any other organ, bringing that vintage style that will make the difference.
