IMPORTANT SAFETY PRECAUTIONS

Please read and observe the following safety points at all times.

WARNING - Power Sources

Do not plug your Monster PowerSource into a power outlet that differs from the source indicated
for safe use on the Monster PowerSource. If you don’t know the type of electrical power that is supplied

to your place of business, please consult your local power company.

WARNING - Grounding and Polarization

A. Your Monster PowerSource 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 into your
outlet, do not attempt to force it. [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.]

B. If you use rooftop devices such as Satellite dishes, antennas, or any other component with
wire that connects to your PowerSource, 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 harmful voltage surges and static discharges, 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 severe physical injury and may result in death.

ii

WARNING - Liquid: Avoiding Electrical Shocks

Do not operate your Monster PowerSource if liquid of any kind is spilled onto or inside the unit.

Do not operate your Monster PowerSource near rain or water that’s spilled or openly exposed (e.g., bathtub,
kitchen or bathroom sink).

WARNING - Power Cord Safety

A. When routing your Monster PowerSource 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.

B. 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
PowerSource immediately. See the warranty section of this owner’s manual (page 29).

WARNING - Proper Cleaning

In general, the only cleaning necessary for your Monster PowerSource is a light dusting.

Unplug your component from the wall outlet before cleaning it. Do not use any type of liquid or aerosol cleaners.

iii

WARNING - Storm Precautions

In the event of a lightning storm, immediately disconnect your Monster PowerSource
from its power source. It’s not necessary to disconnect any components from your Monster PowerSource.

WARNING - No User Serviceable Parts Inside

If, for any reason, your Monster PowerCenter 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 PowerSource to direct sunlight or place it near wall heaters, space heaters,
or any enclosed space prone to temperature increase (e.g., car trunk).

iv

PROPER GROUNDING AND INSTALLATION TIPS

CAUTION - Proper Grounding

Monster PowerSource requires a properly grounded 3-wire outlet to protect connected equipment. If your AC outlet
is improperly wired (no ground or reverse polarity), the green ”SYSTEM GROUNDED” LED on the front panel
of the Professional Reference PowerSource PRO7000 will not light up.

Many older buildings are inadequately wired. It’s very common for a building to be improperly grounded.
Building wiring and grounding must conform to applicable NEC (USA) or CEC (Canada) codes. If you’re not sure
about the wiring, have it checked by a qualified electrician.

IMPORTANT NOTE- Proper Power and Protection

To completely deliver clean power and protect your equipment from electrical surges, every phone, coaxial cable,
and AC power cord in your system must be connected to an appropriate Monster PowerSource outlet.

MONSTEROUS INTRODUCTION

Thank you for purchasing Monster Power’s Professional Reference PowerSource™ PRO7000. PowerSource products
reflect Monster’s commitment to creating performance - enhancing solutions for stage and studio, delivering
superior tone and sound quality.

Ordinary AC power accessories may seriously compromise the equipment they power. The advanced
technologies and innovative design of the PowerSource solves this problem and offers unique convenience
and performance features.

While the PowerSource does an excellent job of protecting your components from harmful power surges,
its main benefit goes beyond that. Exclusive Clean Power™ filter circuitry virtually stops noise in its tracks.
Distortion that typically runs right through other surge protectors is attenuated. It simply isn’t enough to only filter
the noise on the incoming power line. That’s why your PowerSource also features revolutionary separate isolation
for digital, analog, and computer. If any internally-generated noise from an electronic product plugged into
an outlet gets through our Clean Power™ noise filters, it still has to run through yet another filter! The result
is high quality tone and sound that’s free from performance-damaging interference.

MONSTER’S PATENTED CLEAN POWER STAGES

Each PowerSource has its own Clean Power
to high-performance analog, computer and digital reproduction: filtration and isolation. The higher the Clean Power

™

stage. Clean Power™ performs two tasks that are vital

™

stage number, the more sophisticated and advanced the filters. Also, the higher the number, the greater the isolation
between connected equipment for maximum component-generated noise rejection. In addition, the PRO7000 features

™

Clean Power

Stage 5 with a pair of triple-shielded isolation transformers for the best possible performance.

What exactly is Clean Power™ Stage 5? It’s five ultra-advanced isolation filters that include two separate
digital filters to accommodate a pair of digital sources, plus analog, computer, and ultra-high-current audio filters
for the best AC power line noise rejection and inter-component isolation making it ideal for studio
and professional systems.

MONSTER’S CONFIGURABLE NOISE REDUCTION ISOLATION TRANSFORMERS

First, it’s important to understand that the power company’s 120V AC power is delivered unbalanced, with neutral
connected to ground. Special triple-shielded isolation transformers were designed for the PRO7000, configurable
in two ways. A switch on the rear panel selects between the two Noise Reduction Modes.

Normal Isolation Mode disconnects or ”floats” neutral from ground while knocking down noise with Clean Power
Stage 5 filters. Balanced operation makes use of the Stage 5 filters, but activates a center tap on the transformer
secondary output. For the technically-minded, “balanced” means the transformer outputs +60 to -60VAC (volts AC)
with respect to ground. That’s why Balanced isn’t isolated from ground, and why, if your system isn’t very carefully
set up to eliminate ground currents, you may hear hum and buzz from your speakers. This is especially true for systems
adding video to audio, where it’s common to discover “dueling grounds”. Balanced configuration can offer lower noise
because of the topology’s inherent noise-cancelling behavior, or CMR (Common Mode Rejection). Improvements
from balanced running can be most easily perceived in complex CI installations using all-balanced power supplies.

MONSTER T2 TECHNOLOGY

The Monster Power Professional Reference PRO 7000 features Monster’s exclusive T2 technology. T2 is an active
electronic microprocessor-controlled circuitry that sits in front of the surge protection MOVs in Monster Power products.
T2 monitors the line, neutral and ground lines and disconnects the Power Center (and so its outlets) from the AC power
line when a long duration low voltage sag or high voltage swell occurs — that’s continuous voltage below 80Vrms or
above 132Vrms. (RMS stands for “root mean square” and describes average power delivery.)

When the voltage sags or swells to unsafe levels, lightening-fast T2 circuitry shuts down the Monster Power Center for
15 seconds, well before surge protection MOVs turn to mush! MOVs just aren’t designed to endure
long-duration over-voltage conditions.

When the sag or over-voltage condition clears, T2 reconnects the Power Center — and its outlets —
after 15 seconds. If the fault condition does not clear, the T2 comparator circuit shuts the unit down again
for 15 seconds before checking again.

Most power conditioners, including Monster, use thermal fuses to sense overload conditions as well. Although
a good safety feature, by the time the thermal fuse pops, the MOVs will be totally cooked and work as well
as a lima bean to absorb power line spikes. Once again, T2 to the rescue! Monster’s unique circuitry shuts
the power center down before the thermal fuse trips so the MOVs aren’t trashed.
