High-performance audio/video gear needs state-of-the-art power conditioning and protection to keep it safe and to help it deliver optimal performance. PS Audio's Duet Power Center uses a highly advanced filter design to purify and distribute up to 1750 watts of clean, safe and unrestricted power. You'll hear real sonic improvements — powerful, better-defined bass and smoother, more transparent highs. You'll also see the difference on your TV screen, in the form of a better, cleaner picture.

PS Audio builds the Duet to the highest quality standards. A compact solid aluminum casing houses 1/4" inch thick solid copper power bars, heavy extruded aluminum covers and nickel-plated, hand-polished AC receptacles. Microprocessor-controlled protection circuitry guards against power spikes, and automatically disconnects the unit from your power line in the event of extreme high or low voltage conditions. The result — your equipment runs smoother and lasts longer.

From the review PS Audio Duet Power Center
"I plugged the Duet into my plasma TV, and immediately saw a difference in picture quality. At first it was hard to say exactly what that difference was. I soon realized the picture contrast was better than I have ever seen before. The black level was darker, the whites were brighter, and the colors were richer."

Excellent quality for the money. If you are serious about protecting your system

happy you spent the money.



As advertised

Crutchfield Customer Review (What's this?)

The PS Audio Duet power conditioner works as advertised, and as the various positive reviews in several audio publications suggest. I have my stereo power amp, and outstanding amp, plugged into the duet, and the improvement was immediately obvious - clearer presentation across the audio spectrum including an impressive widening of the soundstage. The duet made the an already world-class amp, even better. Highly recommended.

This unit has blocked 97% of the noise generated by a treadmill, used in
another part of our house. Before I would pick up loud noise on my
expensive receiver. I would not of believed it, untill I purchased this unit
and tried it for myself. Crutchfield thanks again for great service and fast

Crutchfield Customer Review (What's this?)

Being an owner of a PS Audio High Current Ultimate Outlet, I was intrigued by the claims for this new product that replaces it. I've seen the videos at PSA, read the online reviews, etc.

They were correct in changes that I've seen. Now, as far as audio changes, I'm not a critical listener, and can't comment on those changes.

There was however quite a difference in my video performance. So much so, that the black levels dropped dramatically, I just had to re-adjust them. Video detail is also even cleaner than before, with excellent dynamic range.

This product was definitely worth the expense, it delivers even better performance, plus an extra set of outlets!

The added bonus was ordering the unit through Crutchfield, with free shipping!

Warranty Note


Overview: The PS Audio Duet Power Center is a state-of-the-art high-end surge protector that provides component level AC cleaning and protection in a compact package. The Duet provides 4 AC outlets and 2 independent isolated zones. The unit provides true surge and spike protection, over and under voltage protection and differential and common mode AC filtering. The PS Audio Duet Power Center is built to the highest standard internally and externally by featuring 1/4-inch think solid copper power bars, 11 gauge copper wire, heavy extruded aluminum covers and nickel plated hand polished Power Port AC receptacles.

True Surge Protection: The Duet Power Center features true protection from surges, spikes and transient events on the power line. Microprocessor controlled over/under voltage sensing offers true surge protection. The unit will automatically disconnect equipment from the AC in the event of a surge.

Replaceable Power Cartridge: The Power Cartridge AC input module contains the surge and spike protection, circuit breaker, over/under voltage control and the first stage of common mode filtering. The unique cartridge is the heart Duet and can be replaced in the field should a problem ever occur.  For instance, if the home is struck by lightning or a surge or spike big enough to damage the cartridge, it easily slides out and can be replaced.

Component Level Filtering: The Duet takes what your wall AC has to offer and cleans everything above 40 kHz where most standard surge protectors start working only at a frequency of 10 to 100 times higher. Using this filtering, the Duet fixes problems associated with noise and improves audio performance as well as video while providing clean power to connected equipment, regardless of the power demands.

Non-restricted Dynamics: The Duet Power Center provides clean, safe and unrestricted power. At 1750 watts, there's enough power for even the most demanding systems. The Duet Power Center will not restrict dynamics or soundstage in any high-end audio/video system. The Duet will provide a superior level of performance in micro and macro dynamics as well as maintain harmonic integrity for audio equipment while increasing color saturation and lower video noise in video equipment.

2 Isolated Zones With 4 AC Receptacles: On the top of the Duet Power Center, the cleaned AC voltage is distributed to your equipment through 2 isolated zones and 4 nickel plated AC receptacles that utilize a magnetic filtering technology based on wound inductors built from strips of Nano Crystalline, high permeability soft magnetic material. This material has approximately 10 times higher permeability than an other magnetic material produced. High permeability magnetic core materials allow PS Engineers to used a minimal amount of copper wire to build effective filters, thus preserving micro and macro dynamics for both audio and video systems.

Power Port Receptacles: The unit features 4 Power Port AC receptacles that are high-end AV, hospital certified grade 10 to 20 amp AC receptacles. This ensures that the tension is maintained on any male plug that is inserted into the power center giving your equipment an excellent AC connection. Each Power Port AC receptacle features 15 separate coats of nickel and 15 separate hand polishing operations to achieve maximum conductivity and durability.

Conditioners: PS Audio recommends the use of additional power conditioning and regulating equipment such as the PS Audio Power Plant to feed the Duet pure, regenerated AC power if desired.

Mounting: There are several ways to mount the Duet Power center. You can mount the place the unit on the floor or on a shelf. If you mount it on the floor, it can either lay flat on its bottom or be placed at an angle between the floor and the wall due to its truncated triangle shaped base.

Warranty Note
