Description

Make sure you're getting the most out of your home theater equipment with the MAX 5400-PM from Panamax. 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 you`re 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 continuosly 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 1 bank with 2 high current outlets) so that any noise created by an A/V component cannot contaminate the power going to equipment plugged into another outlet bank. From the Manufacturer Level 4+ Power Cleaning and Linear 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. 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. 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. Improve Your Picture and Sound Quality While Protecting Your Home Theater Investment All the features you need to keep your system running clean and safeVoltage 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 in the 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 and 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. Five 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, LAN, and Gaming Ports 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.) Add to this an easy-to-access LAN port pass-thru from the rear panel to the front panel for online gaming and a convenience outlet located on the front panel, perfect for gaming systems and other electronics. Find out more about the M5400 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. Protection for Cable/Satellite/Antenna as Well as LAN and Telephone Lines 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. 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. 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.

  • Works great, but contains features that could now be considered obsolete and unwanted
Size: M5400-PM
I'll start with the surprising good news about this unit - after plugging my HT system components into this device, the picture got brighter on the high-end Sony TV. This was an unexpected shock to the two people who witnessed it because we both spontaneously noticed the picture quality change at the same time, and both of us are very suspicious of snake oil related claims. The power outlet I'm forced to use for our system is on the far end of a GFCI device, so that might be related (for one thing, I can't run ethernet over powerline with this outlet). We run the unit as always-on and control power to the components individually, so I can't speak to the timed shutdown and startup features. We don't have tube equipment or anything that needs to warm up. Our OLED TV prefers to have power at all times even when "off" so it can do panel self-maintenance and download firmware updates, and it controls the soundbar and subwoofer and rear speakers so there's no need for sequencing there. The streaming boxes (Roku, Apple) take little power, and the DVD player is turned on only when being used. So the Panamax is always on. I like the front meters that show both volts and amps, but the quality of the blue LEDs that light the meters is questionable - they are a bit cheap looking and the brightness adjustments are not sufficiently adjustable. This is in contrast to the rest of the unit which feels very solid and well built. The utility value of including protection for phone (landlines) and ethernet is questionable - if you can't provide protection at the point of entry into your house then they are mostly useless. Most HT systems are not located at the same place in the house as the point of entry for the phone lines and primary internet connection. The days of these kinds of things being useful are waning - I'd rather have another pair of outlets. Ditto for the USB port on the front - I've already got plenty of ways to charge my phone. When contemplating this box, I'm most of all interested solely in 120VAC power conditioning. There has been no transformer buzzing or any other kind of noise from the unit I got - it has been utterly silent at all times. We've had no power problems so far that would trip the over- or under-voltage reactions so I can't address how this unit behaves when something like that happens. And I hope I never have to. But the cost of this unit was about 10% of the cost of the electronic components it is protecting, so it feels like worthwhile insurance. *Update 03/05/2024* This product now costs $750, which is $300 more than when I bought it less than 3 months ago. ... show more

  • Protection Confirmed!
Size: M5400-PM
1/2/13 Update: Protection confirmed again! And, again, no simple surge protector would have done this. We experienced a very strange power outage. It appeared to begin with a surge followed by voltage dropping from 120V to 60V (where it remained for about an hour). The Panamax immediately cut the power to everything plugged into it and did not pass the 60V of power through to any of the devices during the outage. Low voltage (below 108V) can also harm electronics! For the rest of my devices (refrigerator, dishwasher, etc.) I had to manually trip the breakers so as to avoid damage to those devices. In the end (other than one CFL bulb), everything seemed to work normally (whether plugged into the Panamax or not). But, this sort of damage is cumulative and not always immediately evident. So, I'd say it is safe to assume that -- at a minimum -- the devices plugged into the Panamax had their life expectancy extended. 7/26/10 Update: The voltage anomaly occurred! This weekend, my electric company -- with no apparent external factors involved -- pushed 125 to 127 volts into my home for the entire weekend (122 to 124 is normal for them). At 127 volts, the Buck stage kicked in and reduced the voltage to 117. The Buck stage continued to supply reduced voltage until the input voltage dropped to 123. The CBEMA curve suggests that computer equipment (and, presumably, other electronic equipment) is designed to function properly at plus or minus 10% of 120 volts. However, functioning properly is one thing and sustaining damage over time is another. This Panamax product is designed to keep the voltage within plus or minus 5% of 120 volts. This weekend, the product performed as advertised. In doing so, it might have prolonged the life of my home theater equipment. No simple surge protector could do that. Original review follows: Until a voltage anomaly occurs, it is hard to know how this unit performs. But, I have no reason to doubt the listed specifications. Based upon those specifications, this unit should provide far, FAR better protection than a simple surge protector. And, it appears to be a far better value than even the entry level voltage regulator from Monster, inc (the AVS 2000). The online manual for the AVS 2000 -- unlike this Panamax -- offers very few specifics on voltage regulation. Here in the wild, wild west, various critters tend to find their way into our electrical grid, thereby shorting things out in sometimes spectacular ways and creating all sorts of havoc, voltage anomalies and blackouts. The damage suffered by my previous A/V system -- then protected by a high quality surge protector -- may well have been caused by these errant critters. My hope and expectation is that this unit will substantially prolong the useful life of my new A/V system. Subjectively speaking, this unit does seem to have improved the picture and sound quality. But, I did not do any side-by-side testing. ... show more
