MindPlace Procyon AVS System Light and Sound Meditation Mind Machine


A pioneer among light and sound machines, the Procyon AVS is a full spectrum audio-visual synthesizer. Essentially, you can now meld a complete spectrum of color choices with your choice of digital sounds. The blending effect can modulate your state of mind in unknowable ways, yet positive ways. Perhaps best of all is the Procyon AVSs functionality to independently program each color channel, which affords the user three simultaneous, yet distinct, stimulation frequencies.

Introducing Procyon, a new kind of light and sound experience; melding a full spectrum of color choices with clean, pure digital sound. The resulting new mediaform can be used to modulate states of consciousness in rich new ways. The Procyon AVSs (audio-visual synthesizer) state-of-the-art color synthesis elements can modulate smoothly between fields of pure color (ganzfeld), through subtle shimmering effects, to full-on flicker frequency range up to 75 Hz. Each color channel (red, green, and blue) is independently programmable, allowing up to three simultaneous stimulation frequencies at once. This variety of innovative visual effects enables a new kind of audio-visual experience, and can closely match color to the desired mental state. It’s easy to see why many consider the Procyon AVS a harbinger of things to come in the world of light and sound machines.
