Descriptions

The Monster Cable AVS2000 boasts a robust design with a sleek and compact footprint, making it easy to integrate into any setup. The device features an intuitive interface with clear LED indicators that provide real-time feedback on input and output voltages, as well as any fault conditions. The eight-outlet design allows you to connect multiple devices simultaneously, with four switched outlets for devices that do not require constant power and four always-on outlets for critical components like routers and modems.

The AVS2000 is engineered with advanced surge protection and automatic voltage regulation, ensuring that your equipment receives a stable and safe voltage supply at all times. This not only protects your devices from potential damage but also helps in maintaining their performance and longevity.

SWITCHED OUTLETS

Outlet banks 1-4 of your AVS 2000 are “switched” outlets.This means you can program them for sequential turn-on. Sequential turn-on is one of AVS 2000’s key features, helping maintain the peak performance of your components. Without sequential turn-on, you’d power all your devices at once, causing unnecessary electrical stresses known as “turn-on surge.”Turn-on surge can overheat system connections, pop circuit breakers, and degrade overall system performance. By sequentially powering your high power loads, you can prevent turn-on surges and deliver all the stable voltage needed to maintain peak performance.

The four switched outlets located on the back of the AVS 2000 can be individually programmed to delay power-up between 1 to 6 seconds.This means in order to program each outlet, you must use the slide switches seen in Figure 3.

OUTLET PROGRAMMING

SAFETY PRECAUTIONS

WARNING Power Sources
Do not plug your Monster AVS 2000 into a power outlet that differs from the source indicated for safe use on the Monster AVS 2000. If you don’t know the type of electrical power that is supplied  to your home,please consult your local power company.

WARNING – Grounding and Polarization

• Your Monster AVS 2000 has a three-wire grounding-type AC plug (a three-prong plug). This plug is designed to be inserted into a grounding-type outlet only. If this plug doesn’t fit directly inside your outlet, do not attempt to force it into the outlet. Contact a local electrician to install the proper polarized outlet. Never attempt to dismantle the plug in any way (or to alter an extension cord) to make it fit into a two-prong outlet. Do not attempt to defeat the grounding feature by using a 3-to-2 prong adapter. Instead, call a local electrician to install a properly grounded outlet.
• If you use rooftop devices such as satellite dishes, antennas, or any other component with wire that connects to your AVS 2000, be sure the wire(s) is properly grounded. Use grounding techniques specified in Section 810 of the National Electrical Code (NEC), ANSI/NFPA 70 (in Canada, Part 1 of the Canadian Electrical Code). This protects against voltage surges and static charges.Do not place any part of an antenna near overhead power lines,or any other power circuit. Do not touch any power line or power circuit. Doing so may cause you severe physical injury and possibly result in death.
• WARNING – Storm Precautions
  In the event of a lightning storm, immediately disconnect incoming signal and power lines (e.g., cable and telephone).
• WARNING – No User Serviceable Parts Inside
  If, for any reason, your Monster AVS 2000 is not operating properly, do not remove any part of the unit (cover, etc.) for repair. Unplug the unit and consult this owner’s manual for warranty and service information.
• CAUTION – Exposure To Heat
  Do not expose your Monster AVS 2000 to direct sunlight or place it near wall heaters, space heaters, or any enclosed space prone to temperature increase (e.g., car trunk).
• WARNING – Liquid: Avoiding Electrical Shocks
  Do not operate your Monster AVS 2000 if liquid of any kind is spilled onto or inside the unit. Do not operate your Monster AVS 2000 near rain or water that’s spilled or openly exposed (e.g., bathtub, kitchen or bathroom sink).
• WARNING – Power Cord Safety
  1. When routing your Monster AVS 2000 AC power cord, do not place it near heavy foot traffic areas (e.g., hallways, doorways, and kitchen floors). Do not create a trip hazard with the power cord.
  2. If your power cord’s protective jacket begins to rip or fray, exposing the internal wiring, shielding, etc., disconnect it from the power source and discontinue use of the Monster AVS 2000 immediately. Please see warranty information.
• WARNING – Proper Cleaning
  In general, the only cleaning necessary for your Monster AVS 2000 is a light dusting. Unplug your component from the wall outlet before cleaning it. Do not use any type of liquid or aerosol cleaners.
• WARNING – Medical Conditions
  AVS 2000 is not designed for use with any medical equipment.

Stabilizer AVS2000 TROUBLESHOOTING

• PROBLEM – The AVS 2000 is not receiving power.
  Possible Cause #1
  The AVS 2000 is not turned on.
• SOLUTION
  • Make sure the AVS 2000’s AC power plug is plugged into a properly grounded 120V wall outlet.
  • Press the ON button on the AVS 2000.
  • In some households, a wall switch may need to be thrown to make the wall outlet come alive. Try turning on the light switches located near the wall outlet powering the AVS 2000.
• PROBLEM
  Possible Cause #2
  Too many devices are connected, causing an overload, tripping the thermal circuit breaker. 
  Please note: The total power consumption on all the components powered by a single AVS 2000 should not exceed 1440 watts continuous or 1800 watts peak.
• SOLUTIONS
  • Disconnect any component that may be overloading the AVS 2000.
  • Press the AVS 2000’s thermal circuit breaker (labeled BREAKER 15A on the back panel) button in to reset. Please allow 10 minutes from the time the circuit breaker is initially tripped before attempting to reset. If you reset too soon, the breaker will prematurely sense power overload and not allow unit to operate.
• PROBLEM
  Possible Cause #3
  The AVS 2000 is defective.
• SOLUTION
  • Please see warranty information.
• PROBLEM – AVS 2000 is not providing power to the components.
  Possible Cause #1
  The component is plugged into a “switched outlet” and the AVS 2000 has not been turned on.

• SOLUTIONS

  • Press the ON button on the AVS 2000 and wait for a few seconds for the components plugged into the AVS 2000’s “switched outlets” to be turned on.
  • Or, plug the component into an “unswitched” outlet.

  Possible Cause #2
  The AVS 2000 is defective.

• SOLUTION
  • Please see the warranty information.
