The Monster Power® HDP 1850G High Definition PowerCenter doesn't just protect your gear against damaging power dips and spikes — it can also save energy and money. Many audio/video components continue to draw a small amount of power when they're turned off. The 1850G's innovative GreenPower option prevents this energy waste. When you turn off your connected HDTV or receiver, or when it "goes to sleep," the GreenPower outlet detects the decrease in power and switches itself off, as well as the outlets for your DVD player, subwoofer, and other gear. You can also use the 1850G's remote to switch off additional outlets, so your components don't run up your energy bill sitting in stand-by mode.

Noise-filtered outlets protect your gear and improve picture and sound quality
On the rear panel you'll find eight outlets grouped into three separate banks. Each bank features noise filters specifically designed to improve the performance of different types of components. Plug your HDTV and Blu-ray player into the High Definition Digital outlets to enjoy a crystal-clear picture, and connect your home theater receiver to a High-Current Audio receptacle for robust surround sound. The HDP 1850G also gives you two sets of "coax" connections to guard against voltage spikes coming through your cable or satellite line, plus connections for phone and Ethernet cables.

Smart circuitry raises power protection to a new level
A sophisticated microprocessor acts as a first line of defense against sudden power spikes. It monitors incoming AC power and immediately disconnects your equipment if the voltage reaches unsafe high or low levels. When the voltage returns to a safe range, the PowerCenter reconnects your system. A front-panel voltage meter makes it easy to keep tabs on your power. Monster's five-year warranty includes $400,000 insurance on properly connected equipment.

Monster Power® HDP 1850G Reviews

Average Customer Review:

1 Review

Does what it should

Written by: Reed L. from Twin Cities, MN on August 11, 2012

It provides a good way to neatly route all cables. Looks nice. Provides enough room for larger grounded cables. It is being used in a newly constructed home theater so wiring is nearly brand new to this part of the house. Sound quality improvement was negligible at best, but It is always nice to have peace of mind and be able to monitor the running voltage of your equipment.

Pros: Works as it should, convenient, attractive design.

Cons: Perhaps a little costly.

Product Research


Overview: The Monster Power HDP 1850G High Definition PowerCenter protects your home audio/video equipment from dangerous power surges and spikes. It has 8 AC outlets, coaxial (F-connectors), telephone (RJ-14) and network (RJ-45) jacks for complete protection. In addition, this unit comes with an RF remote control that allows you to turn off two of the outlets. The HDP 1850G has 5,526 joules of protection, and a digital voltage display on the front panel.

Monster Tri-Mode: The unit's patented Tri-Mode circuitry uses relays, MOVs (Metal Oxide Varistors), and thermal fuses to protect against dangerous power surges, dips and spikes that can travel over all three power lines (Line, Neutral, and Ground). When it senses dangerous power conditions, Tri-Mode automatically disconnects AV components and sounds an audible alarm, letting you know the HDP 1850G has protected your equipment.

Monster T2 Technology: The exclusive Monster T2 technology is an active electronic microprocessor-controlled circuit that sits in front of the surge protection circuitry. It monitors the line, neutral, and ground lines and automatically disconnects the PowerCenter from the AC power line when a long duration low-voltage sag or high-voltage swell occurs (continuous voltage below 80 Vrms or above 132 Vrms). When the under- or over-voltage condition returns to normal, T2 reconnects the PowerCenter to the electricity and resets to full operation after 15 seconds. If the power fault condition does not clear, the T2 circuit keeps the unit shut down.

Monster HD Clean Power Stage 2: The HDP 1850G is equipped with Monster Clean Power Stage 2 technology to filter both AC power line noise and reduce noise generated by your connected equipment. The Stage 2 filtration removes the effect of dirty power for better picture and sound from your HD audio and video equipment.

Monster GreenPower Technology: When your A/V and computer equipment go into stand-by mode, they continue to consume electricity even after you have turned them off. Standby energy waste can account for up to 20% of your home's electricity use, according to the U.S. Department of Energy. Monster Power's GreenPower Technology saves energy by turning off the outlets to some of your equipment when the main component in your rack is turned off. For example, if you plug your HDTV or A/V receiver into the GreenPower control outlet, the HDP 1850G will shut off the outlets to your DVD player and powered subwoofer automatically when your TV or receiver is turned off. When the TV or receiver is turned on, power returns immediately to the outlets for the DVD player and powered subwoofer. A level adjustment screw on the bottom of the unit lets you set the appropriate level to control the outlets for your components.

RF Remote Control: The supplied RF remote control can turn on and off the Ultra-High Current Audio Filter outlets (marked "Main Amp" and "Accessory"). This allows unused equipment to be turned off with a single switch to stop standby energy waste and save money. The remote comes with a wall-mountable base for convenient storage. The remote can be used with more than one RF-controlled Monster PowerCenter when the syncing procedure is performed. Dimensions: Remote: W=1.25", H=2.357", D=0.752"; Base: W=2.356", H=3.452", D=0.689" (0.863" with remote).

AC Outlets: The HDP 1850G has 8 surge-protected, color coded AC power outlets on the rear panel. The outlets include the following technology:

Outlet Name Outlet Type Additional Technology
HDTV/TV GreenPower Control High Definition Digital Filter
Receiver GreenPower Controlled High Definition Digital Filter
Game Console GreenPower Controlled High Definition Digital Filter
DVD/Blu-ray GreenPower Controlled High Definition Digital Filter
DVR/TiVo Unswitched Digital Filter
Cable/Sat Unswitched Digital Filter
Main Amp Switched/RF Controlled Outlet PLC Compatible/Ultra-High Current Filter
Accessory Switched/RF Controlled Outlet PLC Compatible/Ultra-High Current Filter

Powerline Network Compatible (PLC): Powerline Communication, also known as HomePlug, is a new type of home network system that works on your home's existing electrical wiring. Ordinary surge protectors can block PLC signals, but the Monster HDP 1850G is engineered to allow full-speed PLC network communications, while still protecting your equipment and filtering electrical noise and interference. PLC-compatible devices should only be plugged into the two Ultra-High Current Audio Filter Outlets.

Coaxial, Network and Phone Protection: Cable, satellite, modem, DSL, and telephone lines can also carry dangerous power surges and spikes. Two pairs of coaxial (one for cable and one for satellite use), one pair of Ethernet (RJ-45) connections is provided to protect your home network. Also, there are three RJ-14 jacks (1 input, 2 outputs) for phone and DSL lines, incorporating a convenient phone splitter.

Front Panel: The front panel has a bright digital display to indicate the voltage on the power line, a display dimmer, a power on/off switch (for the switched outlets), and a number of LED indicators. The LEDs indicate the following:

  • Clean Power On
  • Protection On
  • Ground OK
  • Wiring OK
  • Abnormal Voltage

Warranty and Connected Equipment Protection Coverage: The HDP 1850G comes with a 5-year limited warranty, and Connected Equipment Protection Coverage of up to $400,000 for 5 years. Details of the warranty and connected equipment coverage can be found in the Owner's Manual.
