The Ultimate Buyer’s Guide
Key Factors to Consider
When shopping for a power conditioner, your first priority should be the type of protection offered. Basic units use sacrificial MOVs (Metal Oxide Varistors) that wear out over time. Professional-grade units, like many we’ve reviewed from Furman and Radial, offer non-sacrificial or multi-stage protection that is more robust. Additionally, look for “EVS” or “Extreme Voltage Shutdown,” which will physically disconnect your gear if the voltage becomes high enough to cause damage.
Understanding Noise Filtering (LiFT vs. Standard)
Noise filtering is what separates a “power conditioner” from a standard surge protector. Standard filtering removes some EMI and RFI, but advanced technologies like Furman’s LiFT (Linear Filtering Technology) ensure that the noise is reduced evenly across the frequency spectrum. This is crucial for audio professionals, as uneven filtering can sometimes lead to phase issues or strange artifacts in high-gain recording environments.
Common Mistakes to Avoid
- Thinking all conditioners are the same: A $50 unit is likely just a surge protector in a rack-mount chassis. Actual conditioning requires heavy internal components like chokes and capacitors.
- Overloading the unit: Most of these are rated for 15 amps. If you plug in multiple high-wattage power amplifiers, you might trip the breaker.
- Ignoring Grounding: A power conditioner can fix dirty power, but it cannot fix a building with a missing ground. Always ensure your wall outlet is properly wired first.
