The Story
Wide-bandwidth differential and common-mode filtering contribute to an ultra-low noise floor and deep, black backgrounds. Twelve component-optimized hospital-grade outlets (4 High/Variable-Current for amps; 8 Linear-Filtered/Constant-Current for Sources and TVs) provide performance, versatility, and flexibility.
And, of course, to complement its remarkable performance, the PQ-909 provides robust protection features: Extreme Voltage Shutdown and Non-Sacrificial Surge Protection, the latter capable of withstanding repeated 6000V/3000A surges — the maximum that can pass through a building’s AC electrical panel.
In addition to a 2-RU rack-mounting kit, the PQ-909 comes with a high-performance AudioQuest-designed 2m PQ-920 AC power cable — a 20A (C19) Monsoon-level cable employing Perfect-Surface Copper+ (PSC+), ZERO-Tech for uncompressed current transients, RF/ND-Tech for the ultimate in Ground-Noise Dissipation, and a flat-to-wall 45º/90º male plug to aid installations in tight spaces.
Key Features
- Differential- and Common-Mode Ultra-Linear Filtering: Ensures consistent, wide-bandwidth noise reduction for black backgrounds and detailed, nuanced sound.
- Transient Power Correction (TPC): Low-impedance circuit provides current-starved amplification components with a reservoir of 45 amps (peak, up to 25ms) for uncompressed current on demand, enabling thrilling dynamic contrasts, bass impact, and control.
- Non-Sacrificial Surge Protection: Withstands multiple transient power surges and spikes up to 6000V or 3000A (the maximum that can make it through a home or office electrical panel). Damage from electrical storms or power-line interruptions is virtually impossible. Set it and forget it.
- Extreme Voltage Shutdown: 140V AC activates main circuit relay in under 0.25 seconds and automatically resets once incoming voltage is within a safe range.
- 12 Hospital-Grade AC outlets: (4 High-Current w/ TPC for power amplifiers, powered speakers and subwoofers; 8 Ultra-Linear Filtered for source components) Provide superior retention strength; optimized for connected device.
- Detachable Power Cable Included: 2m PQ-920 detachable power cable features Semi-Solid Concentric Perfect-Surface Copper+ (PSC+) and Long-Grain Copper conductors; ZERO-Tech (No Characteristic Impedance) for uncompressed current transfer; RF/ND-Tech, which minimizes circuit misbehavior by cancelling induced RF noise; and a flat-to-wall plug to aid installation in tight places. 12AWG | 20A RMS capacity; NEMA male wall plug and IEC C-19 female connector.
- Rack-Mountable: Includes 2-RU rack-mounting kit for simple, secure installations.
