Our take on the Furman Elite-20 PFi

If you have a heavy-duty 20-amp circuit powering your audio/video system, the Furman Elite-20 PFi is the missing link between the AC wall socket and your gear. Its twelve rear-panel AC outlets can accommodate 20-amp or standard 15-amp AC plugs. To maximize the protection and performance of your system, Furman includes exclusive technologies originally developed to meet the extreme AC power demands of professional recording, film, and broadcast studios.

The Elite-20 PFi's outlets accept both 20-amp and standard 15-amp AC plugs. Its power cord must be plugged into a 20-amp receptacle.

Protection for 20-amp circuits

If you have a heavy-duty 20-amp circuit powering your audio/video system, the Furman Elite-20 PFi is the missing link between the AC wall socket and your gear. Its twelve rear-panel AC outlets can accommodate 20-amp or standard 15-amp AC plugs. To maximize the protection and performance of your system, Furman includes exclusive technologies originally developed to meet the extreme AC power demands of professional recording, film, and broadcast studios.

Continuous power monitoring plus advanced noise filtering

The Elite-20 PFi constantly monitors incoming AC, and if it detects a significant overvoltage condition, it automatically shuts off power to all connected equipment. In the case of a sudden voltage spike, many surge suppressors are designed to "take a bullet" and sacrifice internal parts to save your gear. It's a noble effort, but it leaves your system out of commission while you send the suppressor back to the factory for repair or replacement. Furman's suppressor circuitry can withstand multiple high-voltage spikes and keep on protecting your gear.

Power Factor Technology: Like a turbocharger for your amplifiers

Wide-open dynamics are essential for truly exciting sound. To cleanly reproduce instantaneous peaks or "transients" cleanly, from a cymbal crash to a car crash, an amplifier needs lots of high-current power. During these moments, amplifiers — including those in receivers and powered subwoofers — may require more current than is available from your home's AC line. Solution? Plug your amplifiers into the Elite-20 PFi's high-current outlets. Furman's unique Power Factor Technology creates a "current reservoir" capable of delivering over 55 amps of peak current. Your amplifier gets the current it needs when it needs it most.

See and hear the signal, not the noise

The Elite-20 PFi's wide-bandwidth filtration reduces the AC line noise that can mask subtle ambient sounds and fine picture detail. Twelve AC outlets on the back panel are divided into three banks, to isolate your system's digital and video circuits from analog components and amplifiers. This helps prevent noise created by one component from affecting the power going to your other plugged-in equipment. These outlets feature hospital-grade connectors that grip your gear's AC plugs snugly and securely.

Quality power conditioner

Mark from South Jordan, UT on 12/24/2018

Crutchfield Customer Review (What's this?)

If you have a 20 amp circuit and big amplifiers this is a great option. I replaced a Monster signature series power conditioner with this unit. I believe the Furman has lowered my noise floor. I also feel the build quality is a step up. I do wish the power cord was better. It is also too short for my system. I will be upgrading it.

Pros: Solid build quality. Lowered my noise floor.

Cons: I wish the power cord was longer and better quality. I will be upgrading it.

Less Light

Richard from Raleigh, NC on 7/30/2017

Crutchfield Customer Review (What's this?)

Replaced a 15 amp with this system was easy to set up but make sure you have a 20 amp handy. My wife this better because the front has less light at night: my wife made me cover old one with towel for less light. Two days after set up we had big Lighting storm light flicker and TV downstairs went down but everything upstairs on the system was fine.

Pros: Power reserves

Cons: Heavy

Controls and Indicators


Power Factor Technology: Although it's rare for amplifiers to draw more than 4 Amps continuously, for superior performance it is vital that an amplifier's AC filter have low impedance and the capability to accommodate peak current demands far in excess of the RMS (continuous) current rating. The Elite-20 PFi's transient Power Factor Technology circuitry effectively creates a current reserve in excess of 55 amps (peak) that is cleaner and faster than a dedicated line from your local power station, benefiting any connected amplifiers' performance.

EMI and RFI Filtration: EMI and RFI noise entering your A/V system through the AC power line couples to the components and masks low level signals, compromising performance. This low level content is critical because it relays the harmonics and ambience in audio, and the depth and clarity in video. Furman's exclusive Ultra-Linear Filtering Technology dramatically reduces noise, ensuring consistent peak operation regardless of load conditions or the time of day. The Elite-20 PFi also has inter-component isolation and nearly twice the noise filtering of the Elite-15 PFi.

Series Multi-Stage Protection (SMP): SMP is maintenance-free surge suppression, offering AC protection without sacrificing itself in the event of a catastrophic surge. The SMP circuit senses voltages so high that operation is impossible and turns the power off before damage can occur; if the voltage exceeds 140 volts or falls below 85 volts, power is removed from all the outlets and the Extreme Voltage LED lights. The circuit will attempt to re-set automatically within 5 seconds, so manual re-set will only be necessary if there is a permanent wiring fault.

13 AC Outlets: The Furman Elite-20 PFi features one front-panel unswitched AC outlet and 12 rear-panel outlets. The outlets include:

  • Video Bank: The video bank has four 3-prong outlets, two switched and two unswitched (always on). In addition to the Ultra-Linear filter, an ultrasonic filter specifically benefits video components (DVR, DVD player, projector, Plasma and LCD TVs, etc).
  • Audio/Video Bank: The audio/video bank has four 3-prong outlets, two switched and two unswitched. EMI and RFI noise is removed by the Ultra-Linear filter.
  • Amplifier Bank: The amplifier bank has four 3-prong outlets, two switched and two unswitched. This bank offers Power Factor Technology with a low impedance filter and current reserve in excess of 55 amps (peak) to accommodate amplifier demands.
  • Front Panel Outlet: The Elite-20 PFi features a convenient unswitched 3-prong AC outlet on the front-panel. EMI and RFI noise is removed by the Ultra-Linear filter.

Front Panel Lamps: The Elite-20 PFi features two retractable front panel LED lamps, offering an easy way to see the equipment below it, even when your theater lights are off.

12V Trigger: The six rear-panel switched outlets are engaged using the 12 volt trigger input, a 3.5mm mono mini-jack. The two switched outlets in the amplifier bank are delayed five seconds before turning on to avoid any potentially damaging speaker thump. Additional components can be triggered to turn on using the 12 volt output jack, also a 3.5mm mono mini-jack. If you'd rather not utilize the 12V trigger circuit, a bypass switch is located adjacent to the input and output jacks. By depressing this button, all outlets will operate when the front panel power switch is engaged.

Transient Voltage Surge Protection: The Elite-20 PFi features transient voltage surge suppression for standard telephone lines, coaxial cable TV lines, and coaxial satellite lines. There is one pair of phone input/output jacks and three pair of coaxial input/output jacks to protect your incoming phone, cable, and satellite lines. The coax jacks pass Both DC carrier signals and high bandwidth signals with an insertion loss of less than 0.1 dB. All the in-line surge suppressors feature Furman's exclusive Zero Ground Contamination technology; this aids in eliminating audio buzzing and the video hum bars that can result from typical in-line suppressors.

Rack Mount: Brackets are included to rack mount the Elite-20 PFi.

I have my on a dedicated 20-amp circuit. I do not think that a 15-amp circuit will damage the Furman or your components. Of course, you will be limited to 15 amps. [ MICHAEL  Apr 08, 2016 ]
Dean, No, you would not damage the unit. You just wouldn't get the benefit of the additional current due to the extra 5 amps. [ KEVIN  Apr 08, 2016 ]
