INTRODUCTION
Dear Enthusiast:
Thank you for purchasing my Signature Series Monster Home Theater Music Reference Power
Amplifier. I started my Signature Series in 2002 by introducing special versions of the Monster
Power Automatic Voltage Stabilizer 2000, Home Theater Power Source 7000 and Reference
Home Theater PowerCenter 5100. Each of these products represented a breakthrough in
performance and affordability and included special enhancements for audiophiles and videophiles
who appreciate minute attention to detail and elegant design…all geared towards getting
the most from their home theater system.
Now I am introducing my signature line of Monster Reference Home Theater Music Power Amplifiers for those
of you who are passionate about movies and music. I’ve spent years perfecting this design working with renowned
audiophile designers Richard Marsh, Demian Martin and the other dedicated professionals at Monster. After countless
hours of critical listening and dozens of prototype designs, we have finally completed an amplifier that is good
enough to be part of The Head Monster’s Signature Series.
The Home Theater Music amplifiers are designed to please the most demanding critical listeners…like me! I like
to listen to music LOUD with all the complex harmonics and dynamic range reproduced as accurately as possible.
I also like to watch movies and to have the power and responsiveness necessary to reproduce movie soundtracks
from the subtlest rustle of leaves to the most violent explosions. It takes a very special amplifier design to satisfy
the needs of both home theater and music.
I hope you enjoy your favorite music and movies even more with your new Monster home theater music amps.
Monsterously,
Noel Lee
The Head Monster
P.S. Here are some of the unique features of the Monster Home Theater Music Reference Power Amplifiers:
MONSTER MIRRORED AMPLIFIER TECHNOLOGY™— (MMAT™)
The MPA 5150 five channel amplifier uses a current-feedback topology we call MMAT™ to ensure low distortion and greater
clarity even at the highest playback levels. Any signal put into this amp will be mirrored at the output, just amplified, with all
details intact. Monster amplifiers employ fully complimentary differential circuits, so the two halves of the amplifier are mirror
images of themselves — helping lower noise and distortion.
OTHER CIRCUIT INNOVATIONS
At the input end, a balanced complimentary push-pull stage delivers ultra-wide bandwidth performance for
the best reproduction of today’s ultra high resolution 192khz DVD-Audio and Super Audio CD formats. Monster
amplifiers are specially designed to be stable at high frequencies to support DVD-A and SACD.
At the output end, high current MOSFET output transistors deliver instantaneous current for maximum transient impact.
Monster amps provide high current peak delivery for a realistic, exciting home theater and music experience.
1
SEPARATE POWER SUPPLIES
A unique feature of Monster amplifiers, which allow them to outperform any receiver, is that each channel has its own power
supply. Receivers that share a single power supply across all channels will actually deliver far lower power levels than the
maximum power rating when all channels are driven. Monster amps won’t sag when the power demands are high because
they are designed to support the current delivery for each channel independently. Monster home theater music reference
power amps deliver detail, clarity, dimensionality and low distortion audio with powerful bass at virtually any power level.
LOADS OF POWER
The MPA 5150 delivers 250 continuous watts per channel into 4 ohms with all channels driven (150 watts/channel into 8
ohms). Instantaneous peak power exceeds 300 watts into 4 ohms (200 watts/channel into 8 ohms).
LABORATORY-GRADE DIGITAL POWER METERS
Watch how the power meters jump around with your favorite dynamic music passage or explosive movie scene, and which
channels require the most power. That will tell you how much power the amps are delivering and what is required
by the material you are listening to. You’ll be surprised to see how much power some music and movie transients need
to sound as powerful as the composer or director had in mind for the original experience.
Watch the meters as the amplifiers pump out big, powerful, but tightly controlled bass. The separate transformer and power
supply on each channel is the key. Big room-energizing bass, properly recreated, gives the sound a sense of space. Give
yourself a good view of the meters really jumping with power by playing Telarc International’s recording of Tchakowski’s 1812
Overture with Erich Kunzel and the Cincinnati Pops. Just after 14 minutes into the recording, listen to the cannon shots and
watch the amp meters show just how much sheer power is required to accurately reproduce one of the biggest
and most breathtaking transients in recording history.
THE MONSTER BACKBONE
Monster recently introduced a new way of looking at a total home theater music experience. It all starts with the “polluted”
AC power from your wall. Power line noise, spikes, sags, noise from your own components, noise generated from other
devices on the same electrical circuit as your system — all of these are detrimental to the audio experience. To achieve
the best home theater and music listening experience, you must take steps to ensure that the power delivery to all
of your home theater music components is stable and clean.
You can realize a truly amazing home theater music experience if you ensure that the power being delivered to all
of your audio and video components is at a stable voltage and filtered from power line noise. Just as the home theater music
amplifiers are designed to provide all the power (wattage) that is demanded from movies and music, Monster recommends
providing all of the clean and stabilized power (voltage and current) that is needed by your electronics to get all
the performance they were designed to deliver.
Voltage stabilization can be achieved by adding a Monster Power Automatic Voltage Stabilizer to your system (AVS 2000).
“Polluted” power can be cleaned by adding a Monster Power Reference Home Theater PowerSource (HTPS 7000) which
will also isolate your components and protect them from electrical spikes and surges.
By addressing the needs of power quality (stabilized, clean power) and power capacity (powerful amplification) from
your electronics, you can build the backbone for a truly amazing home theater music experience.

INSTALLATION GUIDELINES
Before placing, connecting and using your new Monster Home Theater Music Reference amplifier, please read
through these guidelines to familiarize yourself with the installation specifications.
HEAT DISSIPATION
The Monster Amp is a high current design, and like all amplifiers, will produce heat under normal
operating conditions.
To maintain proper operation of your amplifiers:
DO NOT stack your amplifiers in an enclosed environment such as closets or completely enclosed audio racks.
When placing your amplifier into your audio system allow 3” of clearance on the top and 2” of clearance
on each side to help disperse the heat. Each amplifier should be placed on a separate shelf with space above
and to the sides.
If the amplifiers are required to be mounted in an enclosed environment, the use of a fan is recommended
to remove excess heat from the enclosure.
DO NOT place amplifiers directly on carpeted floors.
An amplifier placed on carpeting restricts the flow of air from the bottom and causes the amplifier to heat
up prematurely. This may also pose a safety hazard because the carpeting may come in direct contact with
the amplifier’s chassis which is a source of heat.
AC POWER LINE
The Monster Amplifiers are designed to operate from a 120V 60Hz AC power line. Connection is made through
a heavy duty grounded power cord. For safety and proper operation DO NOT remove the ground pin, cut the power
cord or use a ground lifting adapter.
For proper operation and the best possible sound, Monster recommends using a Monster Power Reference Home
Theater PowerCenter to deliver clean AC power to protect your Monster Amplifiers from surges and spikes
on the AC power line. Consult your Monster dealer for information or visit www.monsterpower.com.
AUDIO CONNECTIONS
The Monster Amplifiers are designed to operate from a 110V 60Hz AC power line. Connection is made through a
heavy-duty grounded power cord. For safety and proper operation DO NOT remove the ground pin, cut the power
cord or use a ground lifting, 3-to-2 prong adapter.
Speaker cables for the Front Left, Center and Front Right should be of equal length to maintain best delivery
of sound. The Rear Right and Rear Left should also be of equal length even if the cables runs allow one
to be shorted then the other.
OUTPUT METERS
One the major features of the Monster Home Theater Music Reference Amplifiers are the laboratory-grade digital
meters. The meters show the current output of the channel indicated in watts.

TROUBLESHOOTING
The following section lists some basic troubleshooting types should you encounter issues when using your
Monster Power Amplifier(s).
Symptom
Possible Cause
Remedy
Amplifier Does Not Turn On
Power Cord Disconnected
Check power cord and connect to AC Line
Blown Power Fuse
Check Main power fuse on back of amplifier.
Disconnect amplifier from AC before
removing fuse. Replace with same value
fuse only.
Preamp Remote Trigger Cable
Not Connected to Receiver
or Preamp
Verify that the remote trigger cable is
connected to both the amplifier and
the receiver or preamp.
Remote Trigger Out from
Receiver or Preamp
Is Incorrect Voltage.
Remote trigger in requires 3-30V AC/DC
to turn amplifier ON. If the output of the
receiver or preamp remote trigger is not
within this range, the amplifier will not
turn on.
Input Type Selection switch set
to the incorrect input type
Verify that all of the Input Type selection
switches are in the correct positions.
No Sound from One or
More Channels
If using standard RCA connections,
the switch should be set to Unbalanced.
If using XLR connections, the switch should
be set to Balanced.
Input From Receiver or Preamp
is Not Connected
Check Input connections
Speaker Cables Not Connected
to Amplifier or Speakers
Check Speaker connections
Blown Channel Fuse
Verify that the channel fuses have not blown.
If they have, replace with the correct type
and value fuse.
Check the speaker and connections to
the speaker for that channel. Verify there is
no short in the connections or the speaker.
Sound Comes Out of
Incorrect Speaker Channel
Receiver/Preamp Output
Channel Connected
to an Incorrect Input Channel
on Amplifier
Verify that the receiver/preamp output
channel is properly connected to the
corresponding input channel on the amplifier.
Amplifier Output Channel
Connected to Incorrect Speaker
Verify that the amplifier output channels go
to the correct speakers.
