Essential Info

Voltage Regulation
Improve system performance and prolong equipment life by providing a consistent level of optimal power to your equipment.

Improves Picture and Sound Quality
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.

Monitors Incoming Line Voltage and Provides a Visual Indication of Power Level
Panamax’s patent pending AVM circuitry continuously monitors the incoming power as displayed on the digital voltmeter. In case of an undervoltage or an overvoltage, a flashing lightning bolt will be displayed in red in the voltmeter, and power to the connected equipment is automatically turned off if either of these conditions is detected. When voltage returns to a safe level, power to the equipment is automatically reconnected.

Reduces Cross-Contamination Between Components
The M5400-PM is designed to provide noise isolation between 5 isolated outlet banks including 2 high current outlets so that any noise created by an A/V component can not contaminate the power going to equipment plugged into another outlet bank.


More Info

Voltage Regulation
Regulates the output voltage on Banks 1-4 to 120 VAC ± 5 VAC. This is accomplished through two boost stages and one buck stage of voltage regulation. In Boost Stage 1 the voltage is boosted in the 109-119V range, while Boost Stage 2 boosts the voltage inthe 100-109V range. The Buck Stage acts to reduce voltage in the 125-136V range.

LiFT Technology EMI/RFI Noise Filtration
Your audio/video components are constantly being bombarded by electromagnetic interference (EMI) and radio frequency interference (RFI) through their AC power source. This contaminated power can affect audio/video equipment and will degrade the overall performance of your entire system. Common symptoms of contaminated power include loss of picture detail, dull colors, pops, hisses, hums and visual artifacts.

Automatic Over & Under Voltage Protection (AVM)
Panamax's patent pending power monitoring circuitry constantly monitors the AC line voltage for unsafe voltage conditions such as momentary spikes or prolonged over-voltages and under-voltages (brownouts). These unsafe conditions pose a very dangerous threat to all electronic equipment within the home. If the MAX 5400-PM senses an unsafe power condition, it will automatically disconnect your equipment from the power to protect equipment from damage. Once the voltage returns to a safe level, the M5400-PM will automatically reconnect the power.

When subjected to a 6,000V (open circuit voltage) / 500A (short circuit current) surge, the M5400-PM limits its voltage output to less than 330V peak, UL's best rating.

If the magnitude of the surge is greater than the capacity of the surge protection components, the M5400-PM's Protect or Disconnect Circuitry will disconnect your equipment in order to protect it. The M5400-PM will need to be repaired or replaced by Panamax if this occurs within the product’s 3 year warranty.

5 Isolated Outlet Banks
The M5400-PM is designed to provide noise isolation between the outlet banks so that any noise created by A/V components plugged into the M5400-PM cannot contaminate the power going to equipment plugged into the other outlet banks of the M5400-PM.

Sequential Startup/Shutdown
Complex audio/video systems may be susceptible to voltage transients generated internally at start-up/shutdown if all of the equipment is powered on or off at the same time. This can cause speaker "thumps" which are not only annoying but can also damage the speakers and/or trip product circuit breakers. The M5400-PM is designed to eliminate these transients by providing a "start-up" delay for the High-Current outlets and a "shutdown" delay for the Switched Outlet Banks. This minimizes in-rush current issues by allowing the components plugged into the Switched Outlet Banks to power-up and stabilize before any amplifiers and powered sub-woofers are turned on. This sequence is reversed during shutdown. The amplifiers and powered subwoofers turn off, their power supplies drain, and then the equipment plugged into the Switched Outlet Banks are turned off.

USB Charger
The M5400-PM features a front panel convenience charger for mp3 players, cell phones, video game controllers, and other small electronics. NOTE: Some devices may not be compatible with this USB charger.

Gaming LAN Port
The M5400-PM features an easy-to-access LAN port pass-thru from the rear panel to the front panel. Perfect for online gaming.

Gaming Outlet
The M5400-PM features a convenience outlet located on the front panel. Perfect for gaming systems and other electronics. 120VAC ± 6VAC

Voltage Sense Trigger
The M5400-PM voltage sense trigger input uses a standard 3.5mm (1/8") mini-mono plug. This feature provides an ON/OFF trigger for the M5400-PM using a Direct Current voltage signal. Many components such as pre-amplifiers and receivers have a DC trigger built in, and will transmit a constant power signal when turned on and in use. The presence of this power signal will turn on the M5400-PM's switched outlets. When the source component is turned off, the voltage trigger signal is also turned off and the M5400-PM's shutdown sequence is initiated. An AC Adapter of the appropriate voltage plugged into a switched outlet may also be used if a DC trigger is not built in.

Cable/Satellite/Antenna TV signal protection
Coaxial protection circuits achieve optimum signal quality from our new coaxial protectors that have the smallest signal loss on the market - less than 0.5 db of attenuation from 0 MHz to 2.2 GHz. Our upgraded coaxial protection has been specifically designed to virtually eliminate signal loss. The clamping level of 75V will meet the demands of both cable and satellite voltage while minimizing exposure to damaging spikes and surges.

Telephone Line Protection
Digital video recorders and satellite TV receivers require a telephone line connection for TV show scheduling and/or Pay-Per-View services. The M5400-PM also provides surge protection for this line. One pair of RJ-11 telephone jacks is provided for this. The circuitry utilizes auto-resetting PTCRs and solidstate SIDACtors for reliability and unsurpassed protection. The clamping level of the M5400- PM's telephone protector is 260 volts. This will allow typical ring voltage (90-130VAC) and operating battery voltage (-48DC) to pass through the circuit and still protect the modem in your satellite receiver from damage.

LAN Protection
Protection circuits for 10/100 baseT Ethernet lines. Incoming LAN line MUST be plugged into the LINE jack. Patch cord to the equipment MUST be plugged into the EQUIP jacks. 1 LAN jack goes to the front panel output jack.8 wire protection, 52V clamping.

JOEEPH C -- centerville, OH   4/26/2010
Great product! Cleaner picture and richer/more promanent bass.
SVEN -- brentwood, MO   3/30/2010
It's somewhat difficult to review the performance of this item, since one really doesn't "see" it do much. Unless, I suppose, one has cruddy power from the utilty company. In any case, this is Panamax's high-end non-UPS unit for regular home use. The M5400 has plenty of bells and whistles, and I bought it for voltage regulation and extra peace of mind for my fairly expensive home theater system. Especially since my location gets a lot of thunderstorms. I gave it 4 stars because the first unit I received was faulty. It was replaced for free by SmartHome, and the one I have now works fine.
VICTOR -- chicago, IL   3/29/2010
Great product! Did everything as advertised.
MICHAEL -- santa rosa, CA   3/23/2010
The product looks nice, but it is like insurance, you don't know how good it is until you need it. So far I haven't needed it.
