iFi Audio AC iPurifier
Active Noise Cancellation. The AC iPurifier uses Active Noise Cancellation to cancel all incoming EMI or RFI noise. This is the same tech as in active noise-cancelling headphones!
Polarity Earth Diagnostics. The AC iPurifier’s smart diagnostics system helps to avoid potential issues by indicating both correct polarity and whether the system has a ground/earth in place.
Intelligent Ground. iFi calls this circuit Intelligent Ground because it will not create a ground loop (a common cause of buzz or hum) even if the system is already earthed.
