Indeed and this is actually a big deal. After all, we can’t afford a P20 for each piece of kit that needs powering! Injected noise from connected equipment is real. Fortunately we have solved this problem, or at least mitigated it to satisfaction, by several means. The way we built the P20 internal power delivery system and the low output impedance of the P20. Internal to the P20 is a series of gold plated thick copper buss bars connecting the AC receptacles together. This means there’s nearly nothing standing between the regenerator’s output and the receptacles delivering the power. The next thing, and this is the most important, is the output impedance. Because we design around a Class AB amplifier, while other regenerators tend to be Class D, we have the advantage of huge peak current delivery and extraordinarily low output impedance. This means that connected equipment cannot generate a noise voltage across the receptacle, thus isolating products connected to the P20.
