Furman AC-215 Power Conditioner Surge Protector

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.
