MONSTEROUS INTRODUCTION
Thank you for purchasing the Monster Power Professional Reference Automatic Voltage Stabilizer™AVS 2000 PRO.
The AVS 2000 PRO is designed to stabilize power line fluctuations and maintain constant voltage
to your professional components.
Voltage sags (below the standard RMS value of 120 volts) are often caused by power- hungry devices which
draw more power (over 1800 watts) than your studio was designed to support. This can have a direct effect
on professional studio components, including amplifiers which require high power levels to operate
at optimum performance level.
As a result, sound can lose tone and clarity. Amplifiers change gain structure resulting in easy-to-hear distortions.
They also won't deliver peak power, dropping from 100 watts to as low as 60 watts! Your professional gear
is very power hungry, too, often drawing twice as much power as a computer and other high power analog
components combined. This causes even more voltage sags and ultimately compromised studio gear performance.
With the AVS 2000 PRO, all your high power devices will maintain the stability needed to deliver peak power
and performance. You’ll enjoy the smoothest, most natural sound and tone. And, thanks to AVS 2000 PRO’s
sequential turn-on feature, your high power loads can operate at peak performance without causing
unnecessary electrical stress that can often pop a circuit breaker or damage your components.

BEHIND THE MONSTER STABILIZER DESIGN
Richard Marsh –There are few experts able to solve the complex problems of AC power,
and Richard Marsh is one of the illustrious few. He’s designed best-selling power conditioners
costing more than $3,000, and now brings his expertise to Monster Power. Richard developed
Monster’s exclusive Clean Power circuitry, and several other groundbreaking designs. Richard’s
background and research into amplifier and capacitors led to the development of the Servo-DC
feedback circuit for power amplifiers –a technique used by virtually every manufacturer today.
His status as the inventor of the MultiCap internal bypass capacitor and the driving force behind
balanced circuitry has influenced the audiophile community for years. Richard is also responsible
for some of high-end audio’s most respected essays and articles, and has contributed
to Fi, The Absolute Sound and Audio magazine. He’s even included in Who’s Who in the West !
Demian Martin –Demian Martin has been solving complex AC power problems for several
years. As a technical consultant for successful paper and steel mills, Demian helped create
several innovative solutions for their power problems. He developed techniques that dramatically
improved the efficiency of high power motor control systems –as much as 50,000 watts
each – helping these companies avoid costly premiums many factories must pay for AC power
inefficiency. He now brings his expertise to Monster Power’s elite research and development team.

Noel Lee –The Head Monster is best known for popularizing the concept of high performance
audio cable over 20 years ago with his creation of Monster Cable. Originally a laser-fusion
design engineer at Lawrence Livermore National Laboratory, and later a touring musician, Noel
has invented or co-invented over 125 U.S. and international patents and drives the explosive
growth of The Monster Group into more than 80 countries worldwide. Monster Power
is his realization of a long nurtured vision of creating affordable power solutions delivering
the best possible sound and picture.

OUTLET PROGRAMMING
Outlet banks 1-4 of your AVS 2000 PRO are “switched”outlets. This means you can program them for sequential
turn-on. Sequential turn-on is one of AVS 2000 PRO’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
stress 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 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 PRO can be individually programmed to delay
power-up between 1 to 6 seconds. This means, in order to program each outlet, use the slide switches
seen in Figure 3.

TROUBLESHOOTING
PROBLEM – The AVS 2000 PRO is not receiving power.
Possible Cause #1
The AVS 2000 PRO is not turned on.
Possible Solution:
• Make sure the AVS 2000 PRO’s AC power plug is plugged into a properly grounded
120V wall outlet.
• Press the ON button on the AVS 2000 PRO.
Possible Cause #2
Too many devices are connected, causing an overload, tripping the thermal circuit breaker.
NOTE: The total power consumption on all the components powered by a single AVS 2000 PRO
should not exceed 1440 watts continuous or 1800 watts peak for long periods of time.
Possible Solution
• Disconnect any component that maybe overloading the AVS 2000 PRO.
• Press the AVS 2000 PRO’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 the unit to operate.
8

PROBLEM – AVS2000 PRO is not providing power to the components.
Possible Cause #1
The component is plugged into a “switched outlet”and the AVS 2000 PRO has not been turned on.
Possible Solution
• Press the ON button on the AVS 2000 PRO and wait for a few seconds for
the components plugged into the AVS 2000 PRO’s “switched outlets”to be turned on.
• Or, plug the component into an UNSWITCHED outlet.
