Power Conditioners with Noise-Dissipation and Non-Sacrificial Surge Protection All three of our new rack-mountable PowerQuest models — the PQ-303, PQ-505, and PQ-707 — take AudioQuest's comprehensive approach to AC power conditioning, addressing noise linearly to provide class-leading, wide-bandwidth noise reduction (better than -22dB). The PQ-303’s Linear Noise-Dissipation comprises Differential-Mode filtering (30kHz–1GHz), which addresses asymmetrical noise already present on the utility line or backwashed via electronic appliances and components. In the PQ-505, Ultra-Linear Noise-Dissipation is achieved with the addition of Common-Mode filtering (30kHz–100MHz) to address symmetrical noise, which is typically picked up by the AC Line, Neutral, and Ground leads. In the PQ-707, Ultra-Linear Noise Dissipation is taken even further with a wider-bandwidth (8kHz to 1GHz) Differential-Mode filter. In addition, the PQ-707 includes Transient Power Correction (TPC). TPC provides a current reservoir of up to 45 amps peak on-demand power for any amplifier (up to 25mS), supplying the low-impedance current the amp needs to produce thrilling dynamic contrasts, bass extension, and control.
