AudioQuest powerquest 505

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.

Better than the wall! Transient Power Correction and 45 amp on-demand current reservoir (shown) enable AQ Niagara level dynamics and jump-factor, like “the artist intended.”

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.

A direction-controlled cable is crucial to maximizing RF-Noise dissipation — Included with every PQ model.

Power to All

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.).

Each AC power bank is isolated and optimized for the connected device, enhancing the PowerQuest's ability to efficiently control the complex interactions of:

1. Radio-frequency noise and other induced noises present in the AC power supplied from the utility
2. The noise that will be present on and in every AC cord
3. The noise that is produced within your system’s components and that “backwashes” into the PowerQuest’s output circuits.

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 is crucial to maximizing RF-Noise dissipation and means each PowerQuest unit is ready to go from the box to the rack in just minutes.

2RU rack mount “ears” included in the box.
