AUDIOQUEST POWERQUEST 303, 505, AND 707 POWER CONDITIONERS

The new AudioQuest PowerQuest 303, 505, and 707 power conditioners feature non-sacrificial surge protection.

The range of AudioQuest PowerQuest Power Conditioners are rack-mountable AC power conditioners. AudioQuest tells us “While these products are presently available in North America only, we do expect EU versions to be available later this fall and UK versions to come sometime thereafter. There will be some significant differences between the NA models and the EU/UK models”.

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. The PQ-505 adds 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, Noise Dissipation is taken even further with a wider-bandwidth (8kHz to 1GHz) Differential-Mode filter.

The PQ-707 also includes Transient Power Correction (TPC). In the PQ-707, 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.

SURGE PROTECTION

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.

All North American models provide 12 total AC outlets: 4 High-Current outlets for variable-current amplification components (power amps, powered speakers, A/V receivers, subwoofers, etc.) and 8 Linear-Filtered outlets for constant-current source components (TVs, media-streaming devices, disc players, turntables, preamplifiers, cable boxes, etc.).

RF Noise

AudioQuest say that each AC power bank is isolated and optimized for the connected device, enhancing the PowerQuest’s ability to efficiently control the complex interactions of RF Noise, noise present in AC cords and the noise that is produced within your system’s components and that “backwashes” into the PowerQuest’s output circuits.

POWERQUEST POWER CABLE

Finally, all models come with optional 2RU rack ears and a detachable 2m PowerQuest power cable with a flat-to-wall plug.

The inclusion of a Direction-Controlled AC power cable for maximising RF-Noise dissipation and means each PowerQuest unit is ready to go from the box to the rack in just minutes.
