Furman Elite 20 PFi Power Conditioner

A 20-Amp Conditioner With Over 55 Amps of Peak Reserve

The Furman Elite-20 PFi is a 20-amp power conditioner with 13 outlets and a Power Factor Technology reserve built for large amplifiers. Furman's manual places its performance second only to the company's Reference series, and it fits a standard 2U rack.

Four amplifier outlets draw on a reserve of 4.5 amps RMS into a resistive load, with more than 55 amps of peak charge. The other nine outlets are filtered, and one of them sits on the front panel. Each outlet group is isolated from the others.

The chassis is 4 inches tall, 17 inches wide and 14.75 inches deep, and it weighs 18 pounds. A detachable power cord and a rack-mount kit come in the box.

Filtering, Reserve and Protection Working Together

Furman rates output at 16 to 20 amps RMS across all outlets combined and asks for a 20-amp supply. The manual says it will run on a 15-amp outlet, but the breaker may trip if continuous draw passes 15 amps.

Linear Filtering Technology (LiFT) cuts differential-mode noise by more than 40 dB from 5 kHz to 100 kHz and more than 80 dB from 100 kHz to 1 GHz. The curve stays linear from 0.05 to 100 ohms of line impedance. Eight outlets add ultrasonic filtering.

Series Multi-Stage Protection (SMP) is non-sacrificial and has zero ground contamination. It clamps at 188 volts peak with a 6000-volt, 3000-amp input. Extreme Voltage Shutdown cuts power if line voltage goes above 140 volts or below 85, then tries to reset on its own.

Furman says Power Factor Technology keeps a power amplifier's big current demands from modulating your low-level analog, digital and video components. The amplifier in turn sees a low-impedance supply of filtered power.

Twelve-volt triggering switches four of the filtered outlets and two of the amplifier outlets. The amplifier pair adds a five-second delay. Two retractable LED lamps with a dimmer light the rack, and the unit also protects telephone and cable or satellite lines.

Who Is This Power Conditioner Best For?

• You own large power amplifiers — the 20-amp rating and larger reserve give them room for peaks
• You run a powered subwoofer — it joins the amplifier bank and shares the reserve
• You have a dedicated 20-amp circuit — the unit is built for steady 20-amp operation, so the full line is available
• You have a mixed rack — eight ultrasonic-filtered outlets serve video and audio sources, so nothing needs a separate strip
• You want an isolation transformer — this Furman has none, so see the Reference models in our power conditioners collection

How Does It Connect to Your System?

Plug the detachable cord into the rear inlet and a grounded wall outlet, ideally on a dedicated 20-amp circuit. Put power amplifiers, receivers and powered subwoofers in the four amplifier outlets. Plug everything else into the other outlets.

Run a 12-volt cable from your receiver or processor to the trigger jack. Keep any master component on an unswitched outlet so a remote can restart it. Use the rack ears or the feet. It is a short job.

Pairs Well With

Building your system? Here are some great companions for the Furman Elite-20 PFi:

• Power cables for your amplifiers and sources
• Stereo amplifiers for the amplifier outlets
• Subwoofers for the high-current bank
• Audio racks with a 2U slot

Frequently Asked Questions

Do I need a 20-amp circuit?

Furman asks for 20-amp capacity. The unit works on a 15-amp outlet. Nuisance tripping can follow if continuous draw passes 15 amps. A dedicated 20-amp line is the clean answer for big systems.

What is Power Factor Technology?

It is Furman's stored current reserve for the four amplifier outlets. Furman specifies 4.5 amps RMS of reserve. It also specifies more than 55 amps of peak charge. Results vary with your amplifier and room.

Will it limit the current my amplifier needs?

Furman says it passes peak current well above its continuous rating. The Power Factor reserve is there to prevent the current compression some conditioners cause.

Which outlets should I use for what?

Amplifiers, receivers and powered subwoofers go in the four amplifier outlets. Everything else uses the filtered outlets, including the one on the front panel.

What is the warranty?

Furman backs the Elite-20 PFi with a three-year limited warranty against defects in materials and workmanship. Register within 15 days of purchase. Otherwise the term drops to one year.
