Matching outstanding AudioQuest performance with non-sacrificial surge protection, the new PowerQuest 303, 505, and 707 power conditioners create excellent foundations for stereo systems, multichannel home theaters, and custom installations.
Performance First
All three rack-mountable PowerQuest models — the PQ-303, PQ-505, and PQ-707 — take AudioQuest’s comprehensive approach to AC power conditioning. They address 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). This addresses asymmetrical noise already present on the utility line as well as noise 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 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.
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.) as well as 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:
- Radio-frequency noise and other induced noises present in the AC power supplied from the utility
- The noise that will be present on and in every AC cord
- 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.
The new PowerQuest models are available now. The US Retail Prices for the PQ-303, PQ-505 and PQ-707 are $459.95, $699.95 and $1,299.95, respectively.
