Executive Overview

Having a good power manager like the Panamax M4300-PM connecting your gear does several things. For one, it cleans up your equipment, giving you a single source to connect all of the AC power for your gear. More importantly, however, it gives you something between your expensive AV equipment and the wall, so that if you ever encounter lightning or any other power surge event, something other than that new LCD or plasma display can take the hit. Panamax has been around for a long time and they are offering some beautiful-looking products to deliver power protection as well as rudimentary filtering of AC line noise (like the kind caused by vacuum cleaners, florescent lighting and similar products). Its power cleaning and linear filtration eliminates common symptoms of contaminated power like pops, hisses, and hums and allows your A/V equipment to perform up to its full capability.

Panamax’s patent pending AVM (automatic voltage monitoring) circuitry continuously monitors the incoming AC power and displays it on the digital front panel voltmeter. This is a blue LCD display that tells you instantly what the power is coming into your A/V equipment. In cases of serious undervoltage or overvoltage, a flashing red lightning bolt will be displayed in the voltmeter, and power to the connected equipment is automatically turned off in order to protect your gear. When voltage returns to a safe level, power to the equipment is automatically reconnected. The M4300-PM is designed to provide complete noise isolation between 2 isolated outlet banks. This includes 5 filtered outlets and 4 high current outlets (for amplifiers and subwoofers) so that any noise created by an A/V component cannot cause noise on equipment plugged into the other outlet bank. All of the outlets are controlled from the front panel's main power button.

The back of the unit, in addition to the 8 AC outlets, has provision for filtering Ethernet (RJ45) and phone line (RJ11) cables as well as two separate coaxial cable feeds. The coax cable protection has a bandwidth of 0-2.2GHz so it should be compatible with all current digital cable and satellite TV services as well as all over-the-air antenna inputs.

There are a few convenience features, too like the fact that one of the switched filtered outlets is on the front, and is dubbed a "gaming" outlet so that you can easily plug in a console or other device directly without having to go around back. There's even a USB output there as well so you can charge up MP3 players, cell phones or other electronic devices directly from the front panel.

The Panamax is a beautiful unit and one that we'd recommend to those who have a focus on protection and who may be short on space. At just under $300, it's not the cheapest unit by far in this category, but with some advanced features like switchable front panel lights, an integrated USB charger and the dedicated front outlet, it certainly has some nice curb appeal. At just 1-3/4" in height, it's also compact enough to fit into just about any location.
