How to Choose the Best Power Conditioners
Advanced Protection Technologies
When selecting a power conditioner, the core protection technologies are paramount. Basic surge protectors, like the Furman Power Conditioner (SS6B), offer essential defense against voltage spikes and include a circuit breaker for overload protection. However, for more sensitive or valuable equipment, advanced technologies provide a significantly higher level of safety. Furman's exclusive SMP Technology, found in models like the Furman AC-215A, is designed to absorb and dissipate extreme transient voltages without sacrificing itself, meaning it can withstand multiple surges that would destroy lesser devices. Similarly, Auto-Resetting Voltage Protection, also present in the Furman AC-215A, detects dangerous voltage irregularities and automatically powers down connected equipment, then safely resets when conditions stabilize. This proactive approach helps prevent damage from brownouts or sustained overvoltage conditions, which a standard surge protector might miss.
Noise Filtration Capabilities
Beyond surge protection, power conditioners excel at filtering out electrical noise that can degrade the performance of audio, video, or sensitive digital equipment. This noise, often referred to as RFI/EMI (Radio Frequency Interference/Electromagnetic Interference), manifests as hums, buzzes, or signal degradation. Furman's LiFT (Linear Filtering Technology), featured in the AC-215A, provides linear AC power filtering, which users typically report leads to noticeably cleaner audio and clearer video signals. Black Lion Audio takes a similar approach with its proprietary PG-P Filtering Technology, claiming an average of three times the noise reduction compared to other portable conditioners in models like the Black Lion Audio PG-P Plus. Even simpler units, such as the Furman M-8X2 Merit Series, incorporate AC noise filtering to reduce RFI/EMI, demonstrating that some level of noise reduction is a common and beneficial feature across various price points.
Outlet Configuration and Portability
The practical utility of a power conditioner often hinges on its outlet configuration and portability. Users frequently encounter issues with "wall wart" power supplies that block adjacent outlets. Models like the Furman M-8X2 address this by offering specific outlets with wider spacing, accommodating bulkier plugs without sacrificing access to other ports. The total number of outlets also varies; while the Black Lion Audio PG-P offers 6 outlets, the PG-P Plus expands to 8, alongside modern conveniences like USB-A and USB-C 5V charge ports, which are increasingly useful for powering accessories or charging mobile devices. Portability is another key factor; the Black Lion Audio PG-P and PG-P Plus are designed for on-the-go use with their compact form factors, whereas rack-mountable units or those with longer power cords, like the Furman SS6B with its 15-foot cord, are better suited for fixed installations where reach is a concern.
Circuitry and Amperage Rating
Understanding the internal circuitry and amperage rating is crucial for ensuring a power conditioner can safely handle your connected equipment. Most household circuits are 15 amps, and many power conditioners, such as the Furman M-8X2, are rated for 15 amps, incorporating a circuit breaker that trips if the total current draw exceeds this limit. This prevents dangerous overloads and protects both the conditioner and your devices. Some compact units, like the Furman AC-215A, are rated for 10 amps, which is typically sufficient for a smaller setup but important to consider if connecting multiple high-draw devices. The presence of an illuminated ON/OFF switch and a "Protection OK" indicator, as seen on the Furman M-8X2, provides immediate visual feedback on the unit's operational status and whether your equipment is actively being protected, offering peace of mind in practice.

Common Mistakes to Avoid
Overlooking Advanced Surge Protection Technologies
A common mistake is assuming all surge protectors offer the same level of defense. Users often purchase basic surge strips without realizing they lack advanced technologies like Furman's SMP (Series Multi-Stage Protection) or Auto-Reset EVS (Extreme Voltage Shutdown) circuitry. While a Furman SS6B provides fundamental surge protection with a circuit breaker, it won't offer the same auto-resetting voltage regulation and high-level spike absorption as the Furman AC-215A, which actively monitors and responds to dangerous voltage irregularities.
Ignoring Specific Noise Filtration Needs
Another frequent oversight is underestimating the impact of electrical noise on sensitive equipment. Many users focus solely on surge protection and neglect the importance of noise reduction. Without features like Furman's LiFT (Linear Filtering Technology) or Black Lion Audio's PG-P Filtering Technology, equipment may still suffer from RFI/EMI, leading to degraded audio clarity or video performance. A basic power strip won't provide the same average 3x noise reduction reported by Black Lion Audio's PG-P Plus, which is crucial for professional audio setups or high-fidelity systems.
Misjudging Outlet Spacing for 'Wall Warts'
Practical usability is often hampered by poorly planned outlet configurations. Users frequently find that bulky power adapters, commonly known as 'wall warts,' block adjacent outlets, rendering them unusable. Selecting a power conditioner like the Furman M-8X2 Merit Series, which explicitly includes 3 outlets with "wall wart" spacing, is a practical solution. Failing to consider this feature can lead to needing additional power strips or leaving valuable equipment unplugged.
Underestimating Power Cord Length Requirements
The length of the power cord can significantly impact placement flexibility and convenience. A mistake is often made by not considering the distance between the power outlet and the equipment setup. While a Black Lion Audio PG-P might come with a standard 9-foot power cable, a unit like the Furman SS6B offers a more generous 15-foot cord. Underestimating this need can result in restrictive placement or reliance on potentially problematic extension cords, which can negate the benefits of power conditioning.
