The Audience aR1p is a surge protector. Read whats on the website. "The aR1p Adept Response provides surge suppression up to 20,000 amps. Whereas surge suppression devices like the ubiquitous MOV (Metal Oxide Varistor) are sacrificial devices and wear out over time, the aR1p surge suppression does not deteriorate. We have also found that MOV devices introduce grudge to audio and video signal. The surge suppression in the aR1p is entirely silent."
