ART PS4x4PROUSB Dual Metered Power Distribution System Review: The Ultimate Professional Grade Solution for Clean Rack Power
I have spent over fifteen years in studios and on stages, and if there is one thing I have learned the hard way, it is that “dirty power” is a silent killer. We spend thousands of dollars on high-end preamps, sensitive digital synthesizers, and powerful computers, only to plug them into a ten-dollar plastic power strip from a hardware store. I remember a session a few years back where a sudden voltage spike at the venue didn’t just cause a “pop”—it fried the power supply of a vintage rack synth that took months to repair. This is precisely why we search for devices like the ART PS4x4PROUSB Dual Metered Power Distribution System. Without proper conditioning, your equipment is constantly battling electromagnetic interference (EMI), radio frequency interference (RFI), and the constant threat of surge damage. Solving this is not just about protection; it is about ensuring your signal remains pristine and your investment stays safe from the unpredictable nature of the power grid. To get the best protection possible, it is worth your time to see its full feature set and user reviews before making your next rack upgrade.

What to Consider Before Investing in a Professional Power Conditioner
A Power Conditioner is more than just an item; it’s a key solution for any professional or enthusiast looking to eliminate unwanted noise floor issues and safeguard against catastrophic electrical failure. In a modern setup, almost every device—from your laptop to your LED studio lights—generates high-frequency noise that can bleed into your audio signal. A dedicated distribution system acts as a firewall, scrubbing that power clean before it reaches your sensitive components. This results in a lower noise floor, clearer high-end response, and a more reliable system overall.
The ideal customer for this type of product is a studio owner, a touring musician with a rack-based rig, or a live sound engineer who needs to monitor incoming voltage in real-time. It is perfect for those who have invested heavily in digital keyboards, rack processors, or communications equipment. While it is an essential tool for these users, it might not be suitable for someone with a very minimal setup who only uses one or two devices, as a smaller surge protector might suffice. However, for anyone building a serious 19-inch rack, the ART PS4x4PROUSB Dual Metered Power Distribution System provides a level of insurance and utility that standard strips cannot match.
Before investing, consider these crucial points in detail:
- Dimensions & Space: In a professional rack environment, vertical space is at a premium. Most power conditioners take up 1U (one rack unit). You should ensure the unit is shallow enough not to interfere with the cabling of the gear mounted behind or below it. The ART PS4x4PROUSB Dual Metered Power Distribution System is designed for a standard 19-inch rack, but you must account for the depth of your power cables and “wall-wart” adapters.
- Capacity/Performance: You need to calculate the total amperage of all the gear you intend to plug in. A standard 15-amp unit like this one can handle up to 1,800 watts. If you are running massive power amplifiers, you may need to distribute the load across multiple circuits or look for a 20-amp unit. For most studio and keyboard racks, 15 amps is more than sufficient.
- Materials & Durability: Look for a rugged steel chassis. Unlike plastic power strips, a professional conditioner is often transported in road cases. The build quality needs to withstand vibration, heat, and the occasional bump during load-in. ART has a long-standing reputation for building “tank-like” equipment that lasts for years in the field.
- Ease of Use & Maintenance: Consider the layout of the outlets. Are they spaced far enough apart to accommodate large transformers? Are the controls on the front accessible? Maintenance is usually minimal, but having clear metering allows you to spot issues with the venue’s power before you even turn on your main gear, saving you from long-term maintenance headaches.

Deep Dive: Performance and Real-World Reliability of the ART PS4x4PROUSB Dual Metered Power Distribution System
To truly understand why the ART PS4x4PROUSB Dual Metered Power Distribution System is a staple in many professional setups, we have to look past the surface and evaluate how it performs under pressure. We put this unit through its paces in both a home studio environment and a mobile live recording rig to see if it lived up to its promises of clean power and reliable distribution.
Advanced Power Filtering (APF) and Noise Reduction
In our tests, the most immediate improvement we noticed was the reduction in “hiss” and “hum.” We connected a high-gain guitar amplifier and a rack-mounted vintage sampler—both notorious for picking up interference—to a standard wall outlet and then switched them to the ART PS4x4PROUSB Dual Metered Power Distribution System. The difference was audible. ART utilizes a proprietary Advanced Power Filtering (APF) system that targets high-frequency noise. Unlike basic conditioners that only use a simple capacitor, this unit employs a more sophisticated network that filters out RFI and EMI. This is a feature that really sets it apart in this price range. We found that the noise floor dropped by several decibels, which is crucial when you are tracking delicate vocal parts or using high-gain settings. As one user noted, this unit helps filter all the noise from the radio power feed in communication racks, confirming our findings in an audio context.
Dual Metering: Monitoring Voltage and Amperage in Real-Time
The standout feature of the ART PS4x4PROUSB Dual Metered Power Distribution System is undoubtedly the dual metering system. Most competitors only offer a voltage meter, which tells you how much juice is coming out of the wall. However, ART also includes a current meter, which shows you exactly how much power your gear is drawing. During our testing, this was invaluable for balancing the load across our rack. If you are plugging in multiple power-hungry devices, you can see in real-time if you are nearing that 15-amp limit. In one instance, we were running a session at an older building where the voltage was fluctuating wildly between 110V and 118V. Seeing that digital readout gave us the peace of mind to continue, knowing that the surge protection was actively standing guard. It is a level of transparency that every professional should have, and you can view the detailed specs of the metering system to see its accuracy range.
Rack Utility: Lighting, USB, and Outlet Layout
Functionality is about more than just electricity; it’s about making your workflow easier. The ART PS4x4PROUSB Dual Metered Power Distribution System excels here. The rear-mounted gooseneck light is, quite frankly, a “godsend” as one user put it. When you are fumbling in the back of a dark rack trying to patch a cable at a gig, that light is the difference between a 30-second fix and a 5-minute struggle. On the front, the pull-out LED lights are dimmable and provide great visibility for the equipment mounted below. Furthermore, the inclusion of two USB charging ports is a brilliant modern touch. I constantly found myself using them to charge my phone or the tablet I use to control my digital mixer. The outlet layout on the back is also well-thought-out, with extra spacing on the ends to accommodate those bulky power bricks (wall-warts) without blocking adjacent outlets. It is clear ART listened to real-world feedback when designing this layout.
Long-Term Durability and Surge Protection
Surge protection is something you hope you never have to use, but when you do, it needs to work perfectly. The ART PS4x4PROUSB Dual Metered Power Distribution System features a fast-acting response circuit that clamps down on spikes and surges before they reach your gear. One user shared a story about a recent lightning strike that motivated their purchase, noting that they learned the “live and learn” lesson. We’ve seen these ART units in racks that have been on the road for a decade and are still “pumping our very sensitive and important equipment safely.” The internal components are robust, and the 2-year warranty provides additional confidence. When you consider the cost of the gear it is protecting, this unit pays for itself many times over in peace of mind alone. If you’re serious about your rig, it’s a smart move to invest in this level of protection today.
What Other Users Are Saying
The general sentiment among professionals and hobbyists alike is overwhelmingly positive. Users frequently praise the ART PS4x4PROUSB Dual Metered Power Distribution System for its “perfect balance of cost, features, and durability.” One industry veteran with over 12 years of experience noted that while they have used many types of power stations, this model is “by far more than reliable” and has saved their sensitive equipment from power problems multiple times without ever failing. Another user highlighted its performance in “the noisiest switching power supplies known to man,” confirming that the filtration is top-tier for amateur radio and communications setups.
On the negative side, feedback is sparse but usually centers on the brightness of the meters. One user mentioned that in a very dark studio, the LED display is quite prominent, though most find the information it provides too valuable to complain about. A few users noted that they wished the USB ports could pass data, but they acknowledged that for a power distribution system, charging is the primary function. Overall, the consensus is clear: this is a reliable, feature-packed unit that punches well above its weight class.
Comparing the ART PS4x4PROUSB Dual Metered Power Distribution System to Top Alternatives
While we believe the ART unit offers exceptional value, it’s important to see how it compares to other industry standards from Furman. Depending on your specific needs for metering or budget, one of these might be a better fit.
1. Furman M-8Dx Merit Series 9-Outlet Power Conditioner
- Digital Voltmeter Displays Incoming Line Voltage
- AC Noise Filtering Reduces Radio Frequency (Rfi) & Electromagnetic Interference (Emi)
The Furman M-8Dx is perhaps the closest direct competitor to the ART unit. It features a digital voltmeter and pull-out lights, much like the ART. However, it lacks the secondary ammeter (current meter) and the front-panel USB charging ports found on the ART PS4x4PROUSB Dual Metered Power Distribution System. The M-8Dx is a fantastic choice for those who trust the Furman brand name and want a simple, reliable voltmeter, but for users who need to charge devices or monitor their total power draw, the ART provides a more comprehensive feature set for a similar price point.
2. Furman M-8Lx 9-Outlet Power Conditioner with Pullout Lights
- 2 Retractable incandescent Front-Panel Light Fixtures With Dimmer Control For Convenient Rack Illumination
- Ac Noise Filtering Reduces Radio Frequency (RFI) & Electromagnetic Interference (EMI)
The Furman M-8Lx is a more streamlined version of the Merit series. It offers the same high-quality surge protection and pull-out lights but completely removes the digital metering. This is an ideal alternative for someone who is on a tighter budget and doesn’t feel the need to monitor their voltage levels constantly. If you already have a very stable power environment and just need reliable distribution and lighting, the M-8Lx is a workhorse. However, you lose the “early warning system” that the meters on the ART unit provide.
3. Furman M-8X2 8-Outlet Power Conditioner & Surge Protector
- AC noise filtering reduces RFI/EMI, Spike & surge protection ensures equipment stays safe & power stays clean,
- 15 amp rating with circuit breaker and "Protection OK" Front Panel Indicator to let you know that your equipment is being protected
The Furman M-8X2 is the entry-level standard for rack power. It is basic, rugged, and effective. It does not include lights, meters, or USB ports. We recommend this alternative for “set and forget” racks where visibility isn’t an issue and you just need to turn eight things on with one switch. While it is more affordable, the lack of filtering depth and monitoring features makes it less suitable for high-end studio work compared to the ART PS4x4PROUSB Dual Metered Power Distribution System. It’s a great “utility” choice, but it lacks the professional “wow factor” and utility of the ART.
