Reliable power for elaborate home theaters

Panamax MR5100

Three isolated AC outlet banks help prevent inter-component interference and noise contamination. You get 11 AC outlets, plus in/out sets of coaxial, LAN, and phone line connections.

The Panamax MR5100 will protect even elaborate audio/video systems from damaging power spikes as well as the minor day-to-day current fluctuations that can compromise your system's performance over time. It can safeguard as many as eleven components, and it also provides a protected front-panel USB charging port for your smartphone, tablet or other portable device.

Top-quality picture and sound start with clean power

The ten rear-panel AC outlets are divided into three isolated banks to reduce inter-component interference and noise contamination. Four of the outlets accommodate high-current components like an amplifier and powered subwoofer. These switched outlets operate on a delay to prevent "speaker thump" when powering your system on and off. Another bank features four "always on" outlets, and the third isolated bank has two switched outlets. The front-panel digital voltmeter makes it easy to monitor the AC power coming into your system.

The MR5100 actually offers multiple layers of surge protection. Panamax's patented Automatic Voltage Monitoring (AVM) technology continuously monitors the incoming power. In case of an under-voltage or brownout (too little electricity), or an over-voltage (too much electricity), a flashing red lightning bolt illuminates and power to your equipment is automatically switched off. When voltage returns to a safe level, power to the equipment is automatically reconnected.

The other layer of surge protection is Panamax's exclusive Protect or Disconnect™ technology. This ultra-fast circuitry completely protects your equipment from catastrophic surges such as those caused by lightning. When that type of extreme event occurs, the MR5100 automatically disconnects AC power to your equipment.

Additional protection for coaxial, phone line, and LAN connections

The MR5100 also provides two sets of in/out coaxial terminals to shield your satellite, cable TV and over-the-air antenna connections. A pair of protected Ethernet jacks let you plug in your laptop and surf the web on a protected connection. And another pair of protected jacks prevents spikes from sneaking in through your phone line.

Crutchfield Customer Review (What's this?)

Improved picture quality after installing. Was able to switch off power to components when not in use. It's also nice to turn off the display.

Pros: Very good quality. No power strip laying on floor

Cons: None

Crutchfield Customer Review (What's this?)

Great product, works exactly as directed. The display is nice so you can keep track of voltage, and I like how you can dim it or turn it completely off.

Pros: Very simple, works great.

Cons: No instructions came with my unit, it would have been nice to have a description of the differences between the three banks, and where you should plug in different components.

Power made easy

Crutchfield Customer Review (What's this?)

I was looking to protect and organize my theater system and the Panamax MR5100 fit the bill exactly. It was in my price range and it still held many of the features of some of the much more pricey model available on the market.

Pros: Easy install and configure. Has both switched and full time outlets. Has plenty of outlets for all my components. Provides protection for the coax and Ethernet lines as well.

Cons: None that I have found yet.

Great protection and power consolidation

11 Protected & Filtered Power Outlets: The Panamax MR5100 features 3 rear-panel banks of AC outlets and a convenient front-panel AC outlet. All of the AC outlet (front & back) include surge protection and power filtration.

  • "Always On" Linear Noise Filtration Outlets (Bank 1): Bank 1 consists of 4 "Always On" AC outlets. These outlets will only power off during a fault condition (under-voltage/over-voltage). Power is cleaned from these outlets by a two-stage balanced Pi filter which also provides noise isolation from the other outlet banks.
  • "Switched" Linear Noise Filtration Outlets (Bank 2): Bank 2 consists of two "Switched" AC outlets. These outlets will turn on immediately and turn off after 10 seconds, via the unit's front-panel Power button. LiFT EMI/RFI noise filtration is provided by a two-stage balanced Pi filter which also provides noise isolation from the other outlet banks.
  • High Current Outlets (Bank 3): Bank 3 consists of four "High Current" AC outlets. The unit's 4 High Current outlets provide power from a low impedance noise filtration circuit that does not limit the current to your equipment. Its output is noise isolated from all of the other outlets.
    Front-Panel AC Outlet:
    The MR5100 also features a protected and noise filtered convenience outlet located on the front-panel. Perfect for temporary gaming systems, portable electronics (such as music players or smartphones), or other personal electronics. This AC outlet is Always On.

Protect or Disconnect Technology: The Panamax MR5100 employs exclusive Protect or Disconnect technology for surge protection. This ultra fast protection circuitry completely protects your equipment from surges such as lightning. When overwhelmed with extreme catastrophic events, Panamax permanently disconnects AC power to equipment.

Level 4 Power Cleaning & Linear Filtration: Level 4 Power Cleaning and Filtration eliminates common symptoms of contaminated power (including loss of detail, pops, hisses, hums and visual artifacts) and allows your A/V equipment to perform up to its full capability.

Automatic Voltage Monitoring (AVM): Panamax's patented Automatic Voltage Monitoring (AVM) technology continuously monitors the incoming power. In case of an under-voltage or brownout (too little electricity) or an over-voltage (too much electricity) a flashing red lightning bolt will be displayed and power to the equipment is automatically turned off. When voltage returns to a safe level, power to the equipment is automatically reconnected.

Signal Wire Protection: Protecting a complete home theater system requires that signal wires coming out of the wall be protected as well. Universal ultra low-loss coaxial protection, as well as LAN/Ethernet protection prevents signal lines from carrying damaging surges while maintaining full high-definition and high-speed Internet signals to your equipment for your connected life.

  • Telephone & LAN Surge Protection: There is one RJ-45 input and one RJ-45 output for 10/100 baseT Ethernet lines, plus one RJ-11 input and one RJ-11 output for standard telephone lines. LAN protection allows for 10/100 base-T Ethernet equipment to integrate into an audio/video system without the risk of upstream surge damage from a gateway, switch, router or other network device. Telephone protection protects your incoming telephone lines.
  • Cable & Satellite Surge Protection: There are two gold-plated coaxial inputs and two gold-plated, threaded, female coaxial outputs for connecting your satellite, cable or antenna TV signal lines. Coaxial protection circuits prevent damaging surges from entering through signal paths and have the smallest signal loss on the market; less than 0.5 db of attenuation from 0Hz to 2.2GHz. Panamax coaxial protection has been specifically designed to virtually eliminate signal loss. The clamping level of 75V will meet and exceed the demands of both cable and satellite voltages while minimizing exposure to damaging spikes and surges.

Digital Voltmeter: The MR5100 features a front-panel Digital Voltmeter which monitors the voltage supplying your home theater equipment. If line voltage drops below 95VAC, or if the line voltage exceeds 135VAC, the display will turn off and the "unsafe voltage" indicator will flash indicating and unsafe voltage condition.

USB Charging (0.5/5V): The MR5100 features a front-panel USB (type-A port) rated at 0.5/5V for charging your Apple iPod/iPhone, Android smartphone, or other USB-enabled electronic device.

8' Power Cord w/ Low-Profile Plug: The Panamax MR5100 is fitted with an attached 8' power cord w/ a low-profile IEC 3-prong plug. This 45° angle low profile plug allows your equipment to be as close as it can get to the wall outlet while not blocking an adjacent outlets. The 8' power cord means your installation location isn't restricted by wall outlet location.

Circuit Breaker: A circuit breaker is located on the back panel of the MR5100. The circuit breaker will trip only if the total current draw exceeds the maximum current rating (15A). This means that collectively, all outlets must draw more than 15 amps before the circuit breaker will trip.

$5,000,000 Lifetime Connected Equipment Warranty: Panamax will replace, pay to replace at fair market value, or pay to repair, up to $5,000,000 of equipment that is damaged by an AC surge while connected to a properly installed Panamax surge protector, if the surge protector shows signs of surge damage or is operating outside of design specifications. For coverage conditions and information on how to make a claim, please see the warranty sheet.

Rack Mountable: The Panamax MR5100 includes rack-mount brackets to mount the unit in your AV rack.

Customer Q&A

Crutchfield asked  
Why did you buy this?

I live in an older building with occasional, unpredictable power "anomalies" -- spikes and split-second outages. I see this as good insurance against damage to my audio video home theater components. [ Roy  Dec 31, 2015 ]

1 question already asked

Yes it does [ JAMES  Oct 04, 2015 ]
It seems to, but only slightly. [ Roy  Sep 28, 2015 ]
Yes, both front displays are dimmed in steps from bright to not visible. [ GEORGE  Sep 28, 2015 ]
Yes. [ Wade  Sep 28, 2015 ]
Yes it does. Good thing because the default setting is really bright. I usually run it in the fully dimmed setting. [ JAMES  Sep 28, 2015 ]
Yes, it does. [ EDWARD  Sep 28, 2015 ]
Yes. There are four levels of dimming, with a fifth choice of display off. The "Bank" buttons dim as well but, due to their functionality, are not turned off when the display is off. [ STEPHEN  Sep 28, 2015 ]
