PROTEUS best-selling member of our family, with redesigned circuitry and processor. Realtime BiColor light output. Proteus controls two color output channels in real time! This means that relaxation frequencies can be set to soothing green, while energizing frequencies are the appropriate red. We deliver the system with superbright Ruby/Emerald LiteFrames.

Proteus uses Flash memory for both session and operating system data. This means that you can download not only new session groups but that the operating system can be upgraded. Wavetable audio. PROTEUS includes stereo audio digital to analog converters, enabling production of binaural beats and other waveforms. Enhanced AudioStrobetm. We've fine-tuned our AudioStrobe decoder circuitry, providing a much crisper, more intense experience. 199 program capacity.
