The IT-Reference 20i has 12 rear-panel AC outlets. A built-in "isolation transformer" feeds noise-free regenerated power to eight of the outlets.
The IT-Reference 20i is Furman's biggest and baddest power conditioner, tipping the scales at a grunt-worthy 81 pounds. It thoroughly cleans and conditions the AC power that is every audio/video component's lifeblood. Its twelve rear-panel AC outlets can accommodate 20-amp or standard 15-amp AC plugs. Furman originally built their reputation by developing equipment to meet the extreme AC power demands of professional recording, film, and broadcast studios.
All electronic components operate best with a steady supply of clean AC power, and high-definition video equipment like Blu-ray players, flat-panel TVs, and projectors are notoriously finicky. The IT-Reference 20i addresses this issue with a built-in "isolation transformer" that feeds noise-free regenerated power to eight of the rear-panel outlets. That puts a stop to noise-inducing ground loops, and power supply backwash between connected components. You'll see noticeably improved picture detail and deeper black levels.
Truly exciting sound requires wide-open dynamics. To reproduce instantaneous sonic peaks or "transients" cleanly, like a car crash or a cymbal 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 amplifier into one of the IT-Reference 20i's high-current outlets. Furman's unique Power Factor Technology creates a "current reservoir" capable of delivering over 80 amps of peak current. Your amplifier gets the current it needs when it needs it most.
The IT-Reference 20i constantly monitors incoming AC, and if an overvoltage condition is detected, power is automatically shut off to all connected equipment. And Furman's rugged surge suppressor circuitry can withstand multiple catastrophic high-voltage spikes and keep right on protecting your system. Three sets of coaxial inputs and outputs protect your satellite, cable TV and antenna connections. And one pair of protected jacks prevents spikes from sneaking in through your phone line.

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 IT-Reference 20i's Power Factor Technology circuitry effectively creates a current reserve in excess of 80 amps (peak) that is cleaner and faster than a dedicated line from your local power station, benefiting any connected amplifiers' performance.
Discrete Symmetrical Power: While differential AC noise (such as electromagnetic and radio frequency interference) can be effectively reduced with a low-pass filter, common mode AC noise (the cause of ground loops and video hum bars) requires a more advanced solution. Effectively reducing common mode noise requires the use of an isolation transformer, the most effective of which is a symmetrically balanced isolation transformer. Furman's Discrete Symmetrically Balanced Power is achieved by routing the incoming AC into a 1:1 isolation transformer with a precisely placed center tap on the transformer's secondary. The incoming voltage (120V on the line terminal and 0V on the neutral and ground) is split into perfect halves on the transformer's output. The AC line now has 60V on the line and 60V on the neutral when referenced to the new center-tapped ground, which remains at 0V AC. What is significant about this is that the two 60V AC terminals are now in opposite polarity, completely canceling all common mode noise from the incoming AC line. This noise reduction is efficient and linear across a huge frequency range; the result is perfectly clean power devoid of ground loops and AC hum noise.
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 137 volts power is removed from all the outlets.
12 AC Outlets: The Furman IT-Reference 20i features 12 rear-panel outlets in five banks:
Transient Voltage Surge Protection: The IT-Reference 20i 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. The coax jacks are bi-directional and pass both DC carrier signals and high bandwidth HD 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 helps eliminate audio buzzing and video hum bars that can result from typical in-line suppressors.
Rack Mount: Brackets are included to rack mount the IT-Reference 20i.

Connected Equipment: Furman Sound's Connected Equipment Warranty covers equipment that is damaged by a transient voltage while properly connected through the Furman IT-Reference 20i to a properly wired AC power line with a protective ground in an indoor location. Furman's Connected Equipment Warranty is limited to the amount of the deductible on the Purchaser's personal property insurance policy, up to $500.00. The Connected Equipment Warranty is in effect for a period of five years.

If the shipping box shows signs of physical damage, we recommend inspecting the product while the shipping company is present. Minor punctures or dents to the box do not often result in damage to the well-padded product inside, so a refusal of delivery is generally not necessary for minor box imperfections. However, should the product itself show signs of damage, it must be refused at the time of delivery for an RMA. Products not refused due to damage at the time of delivery will not be eligible for RMAs. To ensure your full rights to warranty and potential future claims, please have the delivery company note any box damage on file, even if the product itself appears undamaged.
