Performance First
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.
Protection Assured
All models feature Non-Sacrificial Surge Protection and Extreme-Voltage Automatic Shutdown at 140VAC.
If more than 140VAC is present on the incoming AC line for more than a quarter of a second, the circuit will instantly open a high-current relay that will disengage the AC power from all the PowerQuest AC outlets, activating the red front-panel LED “Overvoltage Protection” warning indicator. Once the event has passed, or the building wiring fault has been corrected, the circuit will automatically re-engage.
Take comfort in knowing that valuable gear is well protected.
2m RF-Noise Dissipating cable PQ-716 with Semi-Solid Concentric Conductors using Long-Grain Copper (10amps @240V) and ZERO-Tech for uncompressed current transients and RF/ND-Tech for unprecedented Noise-Dissipation included.
The US cable manufacturer AudioQuest has always given great attention to loss-free transmission. The company has been one of the largest cable suppliers on the high-end market for years.
We use almost exclusively AudioQuest cables at our HiFi & home cinema studios in Berlin-Kreuzberg
