Overview

The Furman AC-215 solves a problem most home theater owners don't fully appreciate until they experience it: dirty AC power. Standard household wiring carries high-frequency noise from other appliances, HVAC systems, and the grid itself — and sensitive AV components translate that noise into audible hum, ground loop whine, and video interference patterns. The AC-215 addresses this with LiFT (Advanced Linear Filtering Technology), which attenuates that electrical noise before it reaches connected devices, and zero ground contamination circuitry that isolates critical video circuits from the ground-path contamination that plagues multi-component systems. The result, in a well-set-up home theater, is a noticeably quieter noise floor and cleaner picture from components that haven't changed.

The protection architecture is what separates the AC-215 from generic surge strips. Furman's SMP+ (Series Multi-Stage Protection Plus) does not use conventional MOV components that absorb and degrade — it redirects surge energy in a non-sacrificial design that remains effective after an event. EVS (Extreme Voltage Shutdown) adds a shutoff mechanism for dangerous sustained overvoltage, which is especially relevant during power restoration after outages. The compact chassis is designed to mount directly to a flat-screen TV bracket using the included adjustable hardware, keeping the unit invisible in a wall-mounted setup. With two filtered outlets and a 15A rating, this is purpose-built for a focused AV installation — a display plus a primary AV component — not a sprawling equipment rack. For that specific use case, it is among the most thoughtfully engineered solutions at its price point.

Pros & Cons

👍 Pros

Non-sacrificial SMP+ surge protection remains active and effective after a spike event — unlike MOV-based strips that silently degrade, this unit doesn't need replacing every time it does its job.
EVS Extreme Voltage Shutdown adds a second layer of protection against sustained overvoltage events, such as the dangerous voltage spikes that follow utility outages and brownout recovery.
LiFT linear filtering visibly and audibly improves signal quality in noise-susceptible AV systems by cleaning the AC line before it reaches connected components.
Zero ground contamination circuitry isolates components from ground-path noise that commonly introduces hum and interference into audio and video circuits.
The compact chassis with adjustable flat-screen mounting brackets is a practical design for home theater installations — it tucks behind the TV without requiring a dedicated equipment rack.

👎 Cons

Only 2 filtered outlets means this unit is not a replacement for a full surge strip — larger AV setups with multiple components will need a supplemental solution for the remaining gear.
The AC-215 is discontinued — finding genuine new-old-stock units means uncertain shelf age, and the current AC-215A is the supported model going forward.
At 3.96 pounds and 11.25 inches wide, the AC-215 is heavier and bulkier than expected for a two-outlet device — the included mounting hardware helps, but it does add mass to a flat-screen wall mount.
The 15A capacity is adequate for most residential AV setups but provides no headroom for high-draw components like large power amplifiers or projectors running simultaneously.
There is no digital display or LED indicators on this unit to confirm filtering status or protection level — you have no visual confirmation that the unit is actively protecting without testing equipment.

Frequently Asked Questions

What does 'non-sacrificial' surge protection actually mean for my equipment?

Traditional surge protectors absorb voltage spikes using MOV components that degrade or fail after a large surge — often silently, leaving your gear unprotected. Furman's SMP+ (Series Multi-Stage Protection Plus) redirects surge energy rather than absorbing it, so the protection doesn't wear out. You don't replace the unit after a surge and hope for the best.

What is Extreme Voltage Shutdown and when does it activate?

EVS (Extreme Voltage Shutdown) monitors incoming line voltage and disconnects all connected outlets if voltage rises to a level that would damage sensitive electronics — think brownout recovery spikes or wiring faults that push voltage well above the 120V nominal. It's a last-resort protection layer beyond surge suppression.

How many outlets does the AC-215 provide, and are all of them filtered?

The AC-215 provides 2 outlets, and both are linearly filtered. This is a compact, focused unit — it is not a power strip replacement for a full rack of gear. It is designed for a specific AV setup, such as a display and an AV receiver or a two-component system mounted to a flat screen.

How does the LiFT filtering affect audio and video quality?

LiFT (Advanced Linear Filtering Technology) works by attenuating high-frequency noise and interference on the AC line before it reaches your components. In practice, this can reduce audible hum, ground loop artifacts, and interference patterns that show up as visual noise on sensitive video displays. The improvement is most noticeable in systems with long cable runs or near other electrical equipment.

Is the AC-215 still available for purchase, or has it been replaced?

The AC-215 is a discontinued model. The current replacement is the AC-215A, which offers updated specifications. If you find the AC-215 available new, be aware it is old stock — verify current availability with the retailer and consider whether the AC-215A better meets your needs.
