The Furman AC-215 is a compact 2-outlet power conditioner engineered to provide advanced AC surge suppression and noise filtering for professional audio and video equipment in space-constrained installations. Measuring only 1.75 inches high by 5 inches wide by 8.5 inches deep, this low-profile device is specifically designed for discreet placement behind flat‑screen televisions, projectors, or beneath AV racks where traditional power conditioners cannot fit. The unit features two front-panel NEMA 5-15R outlets, a master power switch with an illuminated red LED indicator, and a 10‑foot heavy-duty power cord with a standard 3‑prong plug.

Furman's exclusive Series Multi-Stage Protection (SMP) technology provides the highest level of surge and spike protection available by safely absorbing, clamping, and dissipating damaging transient voltages without sacrificing internal components. Unlike conventional surge protectors that fail after a single major event, the AC-215 maintains its protective integrity through multiple voltage spikes, virtually eliminating service calls and equipment downtime. The unit clamps at 188 VAC peak (133 VAC RMS), a threshold significantly lower than the long‑accepted professional standard of 300 VAC peak, even when tested with multiple 6,000 VAC, 3,000‑amp surges.

The AC-215 incorporates Linear Filtering Technology (LiFT), which suppresses AC noise linearly across a broad frequency spectrum to ensure clean power for unequaled audio and video clarity. Traditional AC filter designs can actually add more than 10 dB of noise to the incoming AC line under certain conditions due to resonant peaking, but Furman's LiFT eliminates this issue with zero ground contamination, protecting sensitive digital circuits from data loss or component damage caused by excessive voltage spikes and AC noise. The unit also features Extreme Voltage Shutdown (EVS) circuitry that automatically disconnects connected equipment when incoming voltage reaches 135 VAC or higher, safely powering down until the overvoltage condition is corrected—preventing damage from accidental 208 VAC or 240 VAC connections. The front panel LED indicators provide clear real-time information on power quality and operational status.
