AudioQuest PowerQuest 909 Line Conditioner and Surge Protector

AudioQuest PowerQuest 909 Line Conditioner and Surge Protector Reference audiophile power conditioner • transient power correction • ultra-linear wide-bandwidth RF noise dissipation • non-sacrificial surge suppression • extreme voltage shutdown • 12 AC outlets (high-current & linear-filtered) • 2U rack-mountable chassis The AudioQuest PowerQuest 909 Line Conditioner and Surge Protector serves as a high-performance foundation for reference two-channel stereo systems and demanding custom home theaters. Built upon AudioQuest's Niagara-derived AC power engineering, this flagship 2U power conditioner combines wideband Differential RF Noise Dissipation with non-sacrificial surge protection and Extreme Voltage Shutdown (EVS). Equipped with high-current Transient Power Correction banks capable of delivering instantaneous reservoir current to dynamic power amplifiers and subwoofers, it eliminates AC line grunge, protects valuable electronics against severe power anomalies, and liberates micro-dynamics across connected audio-video components. Key Features & Innovations Transient Power Correction Reservoir — the AudioQuest PowerQuest 909 Line Conditioner and Surge Protector incorporates a current reservoir that provides peak current on demand to high-current outlets, preventing dynamic compression in power amplifiers and active subwoofers. Ultra-Linear Wide-Bandwidth Noise Dissipation — engineered with common-mode and differential-mode AC filtering that dissipates radio-frequency interference and electromagnetic hash linearly over an ultra-wide frequency spectrum without introducing resonant peaks. Non-Sacrificial Surge Protection with EVS — withstands repeated extreme electrical surges and spikes up to 6,000V/3,000A without degrading components, backed by Extreme Voltage Shutdown that disengages power within 0.25 seconds when AC voltages exceed unsafe thresholds. Isolated Linear-Filtered & High-Current Outlets — features 12 total rear-panel AC outlets divided into dedicated isolated banks for sensitive digital source components, analog preamplifiers, and high-demand power amplifiers to prevent component cross-contamination. Included AudioQuest Direction-Controlled Power Cable — packaged with a detachable, direction-controlled AudioQuest power cord optimized to maximize RF noise dissipation right at the wall connection. FAQ — PowerQuest 909 Will connected high-power amplifiers experience compressed dynamics with the AudioQuest PowerQuest 909 Line Conditioner and Surge Protector? No. The AudioQuest PowerQuest 909 Line Conditioner and Surge Protector features dedicated High-Current/Transient Power Correction outlets engineered to supply instantaneous current during loud peaks, preserving uncompressed dynamic headroom. Does the surge suppression mechanism degrade or wear out over time? Unlike standard power strips that use sacrificial metal oxide varistors (MOVs) that deteriorate and eventually fail, the PowerQuest 909 utilizes non-sacrificial surge protection that absorbs multiple high-energy voltage strikes without failing or requiring replacement. Can this unit be mounted into an AV equipment rack? Yes, the PowerQuest 909 features a standard 2U chassis profile and includes removable rack-mount ears for installation into standard 19-inch equipment racks. What occurs during an over-voltage event? If continuous incoming utility voltage rises above approximately 140V AC, the Extreme Voltage Shutdown (EVS) circuit opens a high-speed relay to disconnect all connected equipment, resetting automatically once safe voltage returns.
