Why Sequential Outlets

PP, PT and PS series, all of them have sequential outlets installed. Sequenced powering is often necessary to allow turn-on transients from low level amplifiers and processors to settle down before any power amps are turned on, because simultaneous powering would result in a loud, annoying, and potentially destructive interference reaching the speakers.

Unparalleled Inrush Protection

In any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that cause circuit breakers to trip even though the steady-state currents are not excessive. That’s why ProPower consider sequential outlet a must in Hi-Fi systems.
