The APC H15 Power Conditioner will protect your high performance audio and video (A/V) system from damaging power surges, spikes and lightning. Protection is guaranteed. Isolated noise filter banks will eliminate EMI/RFI as a source of audio and video signal degradation. Data-line surge protection jacks will stop surges traveling over phone and modem or DSL lines. Digital Satellite System, Cable Modem, and CATV Coaxial Cable lines are equally protected.
Sequenced turn-on and off ensures that connected equipment is powered-up/down in the proper order and with the right amount of delay between the stages. It allows you to program a delay into the sequence between 0 and 12 seconds. This feature helps to eliminate any "popping" sounds coming from speakers when turning on the system. This delay feature also eliminates transients that can affect connected components, e.g. digital projectors.
