Our take on the Panamax M8-AV-PRO

The Panamax M8-AV-PRO shields your audio/video system from harmful spikes and surges in your home's AC power. It also filters out the RF (radio frequency) and electromagnetic noise that can keep your audio/video system from looking and sounding its best.

Protection for a variety of inputs, plus expansion options

Panamax m8-0av-pro power line conditioner

The M8-AV-PRO has eight outlets separated into two isolated filter banks to reduce the possibility of interference between components. One bank of four outlets is designed for equipment with higher current demands, such as home theater receivers and powered subwoofers. The other bank of outlets protects the rest of your gear.

You also get three sets of protected coaxial input/output jacks for your cable TV and antenna feeds, plus one input/output for your telephone or Ethernet connection. The M8-AV-PRO's versatile design lets you protect even more components by adding optional Panamax modules.

The MOD-SPKP protects outdoor speakers or keypad or other control lines, while the MOD-DBSTV provides more protection for components with coaxial connections, like additional satellite receivers or cable boxes.

Quick reaction time saves your gear

When a power spike hits, the M8-AV-PRO reacts in less than a nanosecond, breaking the connection to protect your equipment. When the AC voltage returns to a safe level, the Panamax automatically reconnects power.

  • total of 8 protected AC power outlets in two isolated banks

I have had a Panamax M8-AV-PRO for a couple of years now and it works great. This is my second one. Here in Florida there are a lot of thunder storms and brown outs. It has saved my TV and surround sound system many times. I highly recommend the Panamax M8-AV-PRO.

Product Research



Overview: The Panamax M8-AV-PRO Surge Protector features 8 AC outlets controlled by the unit's power switch. The M8-AV-PRO also provides protection for coaxial and telephone connections. It is recommended to work with your High Definition TV. In addition, this surge protector is equipped with 4 diagnostic LEDs. The LEDs indicate Power On/Protection OK, Ground OK, Unsafe Voltage, and DC Trigger.

8 AC Outlets: The 8 AC outlets provide power protection with transformer spacing between outlets.

Noise Isolation: The M8-AV-PRO features two isolated outlet banks to eliminate cross-contamination between components. Outlets 1-4 (on the top of the unit) feature "Balanced Double L" filtration, and are isolated from Outlets 5-8  (on the side of the unit), designed for high current equipment like amplifiers and powered subwoofers. Any noise created by an A/V component in one bank cannot contaminate the power to the equipment plugged into the other outlet bank.

AVM (Automatic Voltage Monitoring): The M8-AV-PRO utilizes an AVM (Automatic Voltage Monitoring) system to protect your connected equipment against prolonged over/under voltages by disconnecting the power when unsafe voltages are detected, and reconnecting it when safe power returns. The M8-AV-PRO will protect your A/V system from catastrophic surges.

Cleaning/Filtration: Common symptoms of "dirty" power include loss of detail, hisses, hums, and visual artifacts. The Power Cleaning and Premium Filtration circuits help your A/V equipment perform to its full capability by eliminating line noise inherent in household current. The result is improved picture and sound quality.

Power Cord: The surge protector features an attached 8 ft power cord with a right-angle, 45-degree offset three-prong plug. The

Telephone/LAN Protection: The M8-AV-PRO has two RJ-45 jacks for use with telephone and LAN lines. The RJ-45 jacks are designed to accept both standard telephone modular plugs, as well as the larger RJ-45 plugs found on Ethernet cables and LAN lines. The unit will protect connected equipment from electrical surges that travel over telephone and network lines.

Note: The telephone/LAN protection circuits operate in one direction only. The jacks are clearly marked "Equipment" and "Line" to help you avoid connecting them incorrectly.

Coax/Satellite Protection: The unit has two separate in/out pairs of coaxial connectors designed to protect your connected equipment from electrical surges that travel over Cable, Satellite, and Antenna lines. The coaxial connectors are bi-directional, so you may connect your equipment into either jack.

12-Volt DC Signal: In addition to surge protection, the M8-AV-PRO has a 3.5mm input for a 12-volt DC signal. When a 12-volt DC signal is received from a source component, the high-current outlets (outlets 5-8) will be turned on. Power to these four outlets is turned off when the DC voltage signal is no longer being received.

Power Switch/Circuit Breaker: The M8-AV-PRO has an On/Off Power Switch and Circuit Breaker. In addition to turning on and off the 8 AC outlets, the circuit breaker disconnects the AC power from the connected equipment when the amp rating for the unit (15 Amps) has been exceeded.

Add-on Signal Line Modules: If your connected equipment has more signal lines that can be protected by the base unit alone, you can add on optional Panamax signal line modules. The MOD-DBSTV (item # 299MODDBST) is for Satellite, CATV, and Cable Modems, while the MOD-SPKP (299MODSPKP) is for Outdoor Speakers and Control Lines.

Mounting: The M8-AV-PRO Surge Protector can be placed on the floor, on a shelf, or inside a cabinet. The M8-AV-PRO can also be wall-mounted using the integrated wall-mount brackets, key-hole slots, and supplied hardware.

Lifetime $5,000,000 Connected Equipment Warranty: Panamax will replace or repair equipment that is damaged by an AC or signal line surge while connected to a properly installed Panamax surge protector (up to $5,000,000).

#1 My old TV is going out and would cost too much to fix. I bought a new TV from Crutchfield as I have in the past. I needed surge protection and I trust what Crutchfield offers.They are from Crutchfield!!! One of the must trusted and respected retailers on the web!! [ SAMUEL B  Aug 07, 2016 ]
I lost my previous AVR during a lightning storm as well as my Apple TV. The surge came through the cable television cable and zapped both components because that path was not protected at all. After purchasing a new AVR on Rex's suggestion, and reading reviews of this product, I finally decided to purchase because of the protection it provides. [ Dan  Jul 31, 2016 ]
Great price and its just what I needed. There were many choices but this offered the best protection. [ Bill  Jun 17, 2016 ]
