Furman PST-8 DIG Advanced AC Power Conditioner — 8 Outlets, SMP & LiFT Technology — Used
The Furman PST-8 DIG Advanced AC Power Conditioner protects sensitive audio and video equipment from the full spectrum of AC power threats — including line noise, voltage surges, spikes, and dangerous overvoltage events — through a combination of Series Multi-Stage Protection (SMP), Linear Filtering Technology (LiFT), and Extreme Voltage Shutdown (EVS). Rated at 15 amps with eight filtered outlets and an 8-foot cord, it delivers clean, conditioned power without sacrificing any of its internal components in the process.
For engineers and integrators searching for the best AC power conditioner for home studio or professional rack use, the PST-8 DIG stands apart from conventional strip filters by employing non-sacrificial surge protection — meaning the unit does not destroy itself absorbing a transient event the way standard MOV-based suppressors do. Its zero ground contamination design never directs voltage to the circuit ground, a critical distinction for protecting digital processors, computer-based recording systems, and other sensitive digital circuits where ground-leaked voltage can cause irreversible damage.
Isolated outlet banks physically separate digital and analog components within the same power strip, preventing high-frequency digital noise from coupling back into analog signal paths — a common source of audible interference in mixed audio/video systems. Telco and cable/satellite transient voltage suppression ports extend this comprehensive protection to connected coaxial and telephone lines, making the PST-8 DIG one of the most complete portable AC power conditioners available for broadcast, studio, home theater, and installed AV applications.
Key Features of the Furman PST-8 DIG Power Conditioner
- Series Multi-Stage Protection (SMP): Provides the highest level of surge and spike protection available in a portable power conditioner — non-sacrificial design means the unit continues operating after absorbing transient events, unlike conventional MOV-only strips.
- Linear Filtering Technology (LiFT): Suppresses AC line noise evenly across the frequency spectrum, eliminating the resonant peaking artifacts introduced by older multi-stage filter designs that can actually add noise to the power line.
- Extreme Voltage Shutdown (EVS): Automatically disconnects all connected equipment when input voltage exceeds 135VAC, protecting against the most statistically common and damaging AC power event without requiring manual intervention.
- Zero Ground Contamination Circuitry: Never redirects surge energy to the circuit ground, safeguarding sensitive digital components — including computer processors and DAW systems — from ground-coupled voltage that standard conditioners can introduce.
- Isolated Digital and Analog Outlet Banks: Four digitally filtered outlets and four linearly filtered outlets are independently isolated, preventing digital switching noise from contaminating analog audio and video signal chains.
- Telco and Cable/Satellite Protection: Two pairs of transient suppression connectors extend protection to coaxial cable, satellite, and telephone lines with less than 0.1dB insertion loss, covering every signal entry point in a connected system.
- Sturdy Aluminum Chassis: Rack-compatible form factor with a durable aluminum enclosure built for both portable and installed applications.
