This report details the technical specifications and recommended practices regarding audio files used with the E-Stim Systems 2B dual-output power unit. The 2B operates as a sophisticated audio-to-sensation transducer; consequently, the quality, dynamic range, and frequency content of the source audio files directly dictate the safety, intensity, and "feel" of the electrical stimulation. This document outlines supported formats, optimal settings, and safety considerations for creating or selecting audio files for this device.
Always turn your power box intensity to zero before pressing play on your media player. Audio Files: The specially designed tracks

Use approved E-Stim Systems power supplies if you prefer to use mains power rather than batteries for stronger, more consistent power.
Now plug in, press play, and let the waveforms take control.
