AudioQuest PowerQuest 2 Power Line Filter

Real Power Conditioning in a Slim, Hideable Box

The AudioQuest PowerQuest 2 is a six-outlet power line filter built to stay out of sight. It has a slim profile and a rugged floor-mounting stand for sliding in behind a cabinet. Power cords plug straight down into the top outlets, which keeps the installation tidy.

AudioQuest says home AC runs on century-old technology, built for light bulbs and motors. Wi-Fi, dimmer switches and LED bulbs add noise on top. In its testing, up to a third of a high-resolution signal can be lost or masked by that noise.

The outlets are sorted by job. Four linear-filtered outlets serve DACs, streamers, preamps and other source or network gear. One High-Current outlet suits a soundbar, AV receiver or powered subwoofer well.

The sixth outlet is a 4K/8K video-optimized outlet. It adds extra noise dissipation tuned for high-resolution video components, so it is the one for your TV, projector or 4K/8K player.

Filtering and Protection Under the Slim Shell

The PowerQuest 2 provides more than 22dB of differential-mode noise reduction from 30kHz to 1GHz. The filter is linearized for line impedance, from 0.05 ohms at the source to a 10 to 50 ohm load. That gives even filtering across the band, not a single sharp peak.

Most surge protectors are sacrificial. After a big surge, the parts are used up and the unit stops protecting, though it still passes power. The PQ-2 is non-sacrificial and is rated for repeated 6,000V and 3,000A surges without wearing out.

Extreme Voltage Shutdown adds a second layer. If incoming voltage goes above 140VAC, the main relay opens in under a quarter of a second. The unit resets by itself once power is safe. Signal-line protection covers cable and satellite TV.

It is rated for 15 amps RMS at 120V. Two USB charging ports share 3.4 amps total for phones, tablets and remotes. A 7-foot AudioQuest power cord is included, so there is nothing else to buy to get started.

Who Is This Power Line Filter Best For?

• You have a compact system. A TV setup, gaming rig, desktop rig or small two-channel room gets real AudioQuest protection without a rack-mount unit
• You own a 4K or 8K TV, projector or player. The dedicated video outlet gives it extra noise dissipation tuned for that job
• You want the conditioner out of sight. It stands behind a cabinet or TV, or lies flat on a shelf, with every outlet still reachable
• You want protection that does not wear out. Non-sacrificial surge protection and voltage shutdown keep working, so there is no spent strip to replace
• You need common-mode filtering, or more than six outlets — the PQ-2 filters in differential mode only and has one High-Current outlet. Larger PowerQuest models in our power conditioners collection, such as the PowerQuest 3, add more outlets

How Does It Connect to Your System?

Plug the included 7-foot cord into a wall outlet. Plug your TV, projector or 4K/8K player into the video-optimized outlet. Plug a soundbar, AV receiver or subwoofer into the High-Current outlet.

Source gear goes into any of the four linear-filtered outlets: streamers, DACs, CD players, preamps, cable boxes, game consoles and network gear. Use the USB ports for small devices. With the stand on, it stands upright. Without it, it lies flat.

Plug in, tuck away, done.

Pairs Well With

Building your system? Here are some great companions for the AudioQuest PowerQuest 2:

• Power cables if you want to go beyond the included 7-foot cord
• Home theater receivers for the High-Current outlet
• Music streamers for the linear-filtered outlets
• HDMI cables to complete a 4K or 8K video setup

Frequently Asked Questions

Which outlet do I use for what?

Your TV, projector or 4K/8K player goes in the video-optimized outlet. A soundbar, AV receiver or subwoofer goes in the High-Current outlet. Streamers, DACs, preamps, CD players and network gear take the four linear-filtered outlets.

Do I need this if I already have a good surge protector?

They do two jobs. A basic surge strip blocks voltage spikes but does nothing for AC noise, and many use parts that wear out. The PQ-2 does both, with non-sacrificial protection and linear filtering from 30kHz to 1GHz.

What comes in the box?

You get the PowerQuest 2, a detachable floor-mounting stand, and a 7-foot AudioQuest power cord. The owner's manual and warranty documentation are included.

Where can I install it?

Behind cabinets or entertainment units, with the stand attached to hold it upright. Remove the stand and it lies flat on a shelf. Either way all six outlets stay accessible.

What's the warranty?

AudioQuest lists a five-year limited warranty for the PowerQuest 2, for the original purchaser in the USA, Canada and Puerto Rico. It covers defects in design, assembly, material and workmanship.
