The Entropy is an analog random voltage source and noise generator. It features sample/track and hold normaled to white noise, with a toggle selection switch sample (switch right position) or track (switch left position) and hold function. An internal pcb trimmer adjusts the spread/gain of random voltages out from “scalar” (low gain, counterclockwise) to large interval jumping (high gain, clockwise).
All analog white, pink, and brown/red noise 10vpp~(dependent on white gain trim). Smooth (infrared) random cv out at 10vpp with 2 range settings from erratic (more events, switch in left position) to almost random rise and fall envelope behavior (less events, switch in right position). White noise pcb trimmer sets the amplitude of the noise which in turn influences the rate of the infra out.
LEDs indicate voltage polarity. Blue for negative voltage and red for positive voltage.
