NEC (National Electrical Code) Standards
A Note for the Cable Television (CATV) Installer
This reminder is to call the CATV system installer’s attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and in particular, species that the cable ground shall be connected
to the grounding system of the building as close to the point of cable entry as practical.
Antenna Grounding Outside the House
If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to
provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the
lead-in wire to an antenna-discharge unit, connection to grounding electrodes, and requirements
for the grounding electrode. See diagram below.
Cable TV Coaxial Cable, Satellite
Dish Cables, and Television
Antennas should be grounded
BEFORE the point of entry into
the house.

Unbalanced RCA Inputs
The MPS-1 has one unbalanced RCA input
available for each amplier channel module. Connect this to the corresponding RCA
jack on your preamplier to provide signal
to the amplier channel. See page 21 for a
connection diagram.
Balanced XLR Inputs
2
The MPS-1 has one balanced XLR input
available for each amplier channel module. Connect this to the corresponding
XLR jack on your preamplier to provide
signal to the amplier channel. If you have
a choice, use the balanced XLR connections
whenever possible. Balanced connections
oer superior noise immunity over unbalanced RCA connections.
On the balanced XLR connector, the wiring
is as follows:
Pin #1 = Ground
Pin #2 = Signal +
Pin #3 = Signal -
Pin #1
Pin #3
Pin #2
3
Speaker Output Terminals
The speaker output terminals for each amplier channel are located just below the
balanced XLR input jack. The top post of
each binding post pair is the positive output, and connects to the positive (red) post
of your speaker. The bottom post of each
pair is the negative, and connects to the
negative (black) post of your speaker. The
posts can accept bare wire, spade terminals,
and dual or single banana connectors.
Spade connections or banana plugs ensure
a simple, solid t in the terminal whereas
bare wire may be awkward when the terminal is screwed down to compress the
wire into place. Keep in mind that if you
use “dual banana” plugs and “stack” them,
you will be creating a parallel connection.
For more details on series and parallel connections, see pages 24-25.
See page 22 for a connection diagram.

Turn On Selector Switch
4
This switch allows you to select how the
amplier will turn on and o.
In the ON (Up) position, the switch on the
front of the amplier is the method you
will use to power up and power down the
amplier. Please note that in this conguration, you must manually power up and
power down the amplier each time you
use it or it will have unnecessary standby
current draw.
In the SIGNAL (Middle) position, the amplier automatically turns on whenever it
senses an audio signal on any one of the
seven amplier channels. The circuit stays
active for a full minute after the absence of
any audio signal to account for quiet passages of music or dialogue.

External Trigger
Connection
Fuse #1
6
This fuse is for the power supply of the MPS1 chassis. It is a TL15AL type rated a 15A, 250
V. If the fuse ever fails, be sure to replace it
with the same type and rated fuse.
In the TRIGGER (Down) position, the ampli-
er’s ON and OFF functions are controlled
by a trigger from a source or preamplier
device. The trigger accepts 12 VDC and will
turn the amplier on whenever a trigger is
present (See #5). When there is no trigger,
the amplier goes into standby mode. This
is the preferred method for activating the
MPS-1.
External Trigger Connection
5
This external trigger connection allows
the amplier to be turned ON and OFF by
a control device such as a source unit or
preamplier. It can also be used with most
home automation controllers. The trigger
requires a 12 VDC trigger. This is the preferred method of activating the MPS-1. See
page 23 for connection details.
Fuse #2
7
This fuse is also for the power supply of
the MPS-1 chassis. It is a TL15AL type rated
a 15A, 250 V. If the fuse ever fails, be sure
to replace it with the same type and rated
fuse.
IEC Line Cord Socket
8
The MPS-1 comes with a detachable line
cord which connects here. Plug the line
cord into an AC wall socket which is correctly configured with the voltage and
current supply specied for the MPS-1. Do
not plug this line cord into a power strip,
it must plug directly into a wall socket. For
more details on AC power considerations,
see page 19.
Page 14
Installation and Connections
Observe the following precautions when choosing a location for your Emotiva MPS-1:
1) Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating
vents and radiators.
2) Do not expose the unit to rain or moisture. If uid or a foreign object should enter the unit, immediately
turn o the power and contact your Emotiva Dealer.
3) Avoid excessive exposure to extreme cold or dust.
4) Do not place heavy objects on top of the unit.
5) If you need to clean the front surface, rst turn o the power and then use a soft dry cloth, rubbing with
the grain. Be careful not to scratch the display window.
Installation of the EPM-300 Power Modules
The MPS-1 is shipped without the EPM-300 power modules installed so that the packaging is not
subject to unnecessary shipping damage. The modules must be installed prior to use, however this
is a straight forward task and is very simple.
Tools Required
You will need a #2 Phillips screwdriver to complete this task. Once the
installation of the modules are complete, you may also need wire cutters
and strippers to prepare the trigger plug and speaker wires for connection
to the MPS-1.
Unpacking the EPM-300 Module
You should have received your MPS-1 in a total of three boxes. The main MPS-1 chassis is in one of
the boxes. The other boxes contain the EPM-300 power modules, one box with ve modules and
the other box with two modules. All of the installation accessories are packaged with the MPS-1
chassis.
Unpack each EPM-300 module one at a time, install the module per instructions, then proceed with
the next one. Avoid touching any of the circuitry or the cooling fan as you handle the EPM-300
module.
Page 15
Page 17
Orienting the Module to the MPS-1 Chassis
Upon removing the EPM-300 power module from the packaging, you must orient which is the “top”
and “bottom” as well as which is the “front” and “back”. The top has a single nylon rail while the bottom has two nylon rails. It is important that the module be placed in so that the rails on the top and
bottom align with the corresponding “rail channels” in the MPS-1 chassis. The front of the module
that will be inserted into the chassis has an AC receptacle and a small printed circuit board while
the back of the module is where you will nd the RCA/XLR connectors and speaker outputs.

not require any excessive force. If you must force the power module in, stop and re-evaluate your
alignment of the nylon guide rails. Excessively forcing the power module can damage it. Use care
not to damage the fan or electronic components during this installation. The power module is fully
inserted when it bottoms out in the back of the MPS-1 chassis.
Completing the EPM-300 Installation
Once the power module is inserted, you must attach it to the MPS-1 chassis with four #2 phillips
screws (provided). The screw holes on the back panel should line up to threaded holes in the MPS1 chassis. Install and tighten the screws, then proceed with the installation of subsequent power
modules.

MPS-1 Installation Accessories
The MPS-1 Modular Power Amplier comes with some additional installation accessories that make
the component t into virtually any installation theme.
Piano Black Wood Side Panels
The MPS-1 comes with attractive wood side panels in a stunning piano black lacquer nish. As this
electronic component is going to be in many homes alongside equally nice furniture, the side panels
allow the MPS-1 to look a little more like it belongs in the room. Although every installation will not
require them, they are included for the owner to use if he/she so chooses.
To clean the piano black nish, simply use a damp cloth (dampened with water) and wipe them down.
Then use a soft dry cloth to dry and bu the nish to its original shine. Do not use any chemicals on
the side panels. Chemical cleaners may cloud the nish of the laquer.
Rack Mount Installation Hardware
In the event the user chooses to mount the MPS-1 in a “rack mount” conguration, the unit has rack
mount ears included. To install the MPS-1 into a rack mounting conguration, the following details
must be completed.
1) The piano black wood side panels must be removed, This is accomplished by simply removing
the four #2 Phillips screws on each panel.
2) The four aluminum feet of the MPS-1 chassis must also be removed. This is accomplished by removing one #2 Phillips screw directly in the center of the foot
3) Remove two #2 Phillips screws attached at the front edge of the side panel.
4) Attach the rack mount ears to the side panels using the longer #2 Phillips screws provided.
5) When installing into a rack mounting position, be sure to provide adequate support from the
sides and/or rear of the unit to avoid any unnecessary stress on the chassis.
6) Be sure the MPS-1 has adequate ventilation. At least 1 empty rack space above AND below the chassis
will allow fresh air to circulate around the unit.
Page 18
AC Power Considerations
Ensure that the unit is plugged into an outlet capable of supplying the correct voltage and current
specied for your model. Remember to account for the electrical power that other components will
require if they share a common wall socket or electrical circuit. The majority of household electrical
sockets in places other than the kitchen and garage are 15 amperes maximum. Most DVD players
and other source components are fairly low current items. When all seven of the power modules
are installed, the Emotiva MPS-1 requires a minimum of 15 amperes @ 120 volts or 8 amperes @ 230
volts. It should be sucient to allow the other devices such as preampliers and A/V source units
to share a wall socket, but power ampliers such as the MPS-1 and a video display (big screen TV or
video projector) should be provided a SEPARATE electrical connection on a SEPARATE circuit. As the
MPS-1 has a minimum requirement that consumes one entire circuit, please use a second (separate)
electrical connection for other devices. DO NOT plug the MPS-1 into a power strip or extension cord
unless the device is specically designed and rated for high current use.
Refer to your preamplier, A/V source component(s), and video display owner’s manuals to learn
the power requirements so you can safely plan your electrical power requirements for your home
entertainment system.
Input Connection Considerations
The MPS-1 contains both unbalanced RCA inputs and balanced XLR inputs. You must choose one or
the other for each channel connected. You cannot use XLR cables in, with RCA out, or RCA in with
XLR out. There is no direct internal connection between the RCA and XLR inputs.
Whenever possible, keep preamp level audio cables away from electrical power cords by at least a
few inches. It’s more important with ampliers as the AC power cords are carrying much more current than other source and preamplier components, which means there is a larger degree of noise
or “hum” potential with the amplier power cord proximity.
Output Connection Considerations
The output connectors provided on each channel of the MPS-1 are standard “binding post” speaker
connectors with industry standard spacing. These are sometimes called 5-way binding posts because
of the many ways in which the speaker wire can connect into the posts. The posts can accept bare
wire, spade terminals, and dual or single banana connectors. Spade connections or banana plugs
ensure a simple, solid t in the terminal whereas bare wire may be awkward when the terminal is
screwed down to compress the wire into place. Keep in mind that if you use “dual banana” plugs
and “stack” them, you will be creating a parallel connection. For more details on series and parallel
connections, see pages 24-25.
Page 19
Page 21
It is important to observe polarity so that the speaker wire connects to the red and black terminals
on the amplifer and the corresponding terminals at the speaker. Also make sure that the positive
speaker wires do not touch the negative speaker wires, or any chassis metal. This will cause a short
circuit and activate the protection circuitry.
Automatic Operation of the Cooling Fan(s)
Each power module in the MPS-1 is equipped with a cooling fan to maintain a safe operating temperature. During normal operation the fan is o. The fan only becomes operational when it is required
to cool the power module at temperatures in excess of 50 degrees Celsius (122 degrees Fahrenheit).
The speed of the fan will increase as the temperature increases. The fan will turn o when the power
module cools to 30 degrees Celsius (86 degrees Fahrenheit).
Connection Tips for Superior Sound
Before setting up your new system, please consider the following:
• Always make sure the MPS-1 is turned o before making or changing ANY connections.
• Whenever possible, route the power cords away from the signal cables or speaker wires to prevent
any hum or interference heard in the speakers.
• Many RCA type patch cords can be a very tight t and there is usually a preferred method of get-
ting them o. Some have to be removed with a twisting action. Be gentle or you may damage the
jacks of your MPS-1, the cables themselves, or other components.
• Many audiophile signal cables are intended to be hooked up in one direction. If this is the case the
cables will be marked with arrows the direction of signal ow.
• It is usual for the right channel RCA patch cord plugs to be red and the left channel connections
to be white, grey, or black (depending on the cable brand). RCA connectors that are gold will be
designated with a colored band to designate the channel.
• If the preamplier to which you will connect the MPS-1 features balanced XLR outputs, use the
MPS-1’s balanced XLR inputs instead of RCA type patch cords. Balanced signal transmission between audio components provides superior rejection of hum and noise, especially if long cables
are required.
Page 20
Connection Diagrams
Unbalanced Connections
If your preamplier has RCA outputs, it can be connected to the amplier inputs as shown. The
amplier will boost the preamplier’s output, up to a level suitable for driving speakers.
Make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis
metal. This will cause a short circuit and may activate the protection circuitry. The 12 VDC trigger
connection shown can be used to turn the amplier on when the preamplier turns on. This is the
preferred method of activating the MPS-1. Alternatively, you could use the amplier’s SIGNAL switch
position. The amplier will then automatically turn on when a preamp audio signal is received.

Balanced Connections
If your preamplier has balanced XLR outputs, it can be connected to the amplier inputs as shown.
The amplier will boost the preamplier’s output, up to a level suitable for driving speakers. The
overwhelming advantage of using the balanced XLR inputs is that there is superior noise rejection
over the common RCA type connections.
Make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis
metal. This will cause a short circuit and may activate the protection circuitry. The 12 VDC trigger
connection shown can be used to turn the amplier on when the preamplier turns on. This is the
preferred method of activating the MPS-1. Alternatively, you could use the amplier’s SIGNAL switch
position. The amplier will then automatically turn on when a preamp audio signal is received.
Page 22
12V Trigger Connections
The 12 VDC trigger connection shown can be used to
turn the amplier on when the preamplier turns on.
This trigger will actually trigger with any switched DC
Voltage from 5-24 VDC, however the majority of home
theater components use a standard 12 VDC trigger
connection for this function. This is the preferred connection as it has the greatest degree of reliability.
Never switch anything that plugs directly into the
wall with this trigger connection. This action will
damage the unit and VOID THE WARRANTY.
If unable to use the trigger connection to activate
the MPS-1, you could alternatively use the amplier’s
SIGNAL switch position. The amplier will then automatically turn on when a preamp audio signal is
received.
The trigger connection plug and turn-on selector
switch are located on the top right corner of the back
of the MPS-1 chassis
Speaker Output Connections
The speaker output terminals for each amplier
channel are located just below the balanced XLR
input jack. The top post of each binding post pair
is the positive output, and connects to the positive
(red) post of your speaker. The bottom post of each
pair is the negative, and connects to the negative
(black) post of your speaker.
Regardless of the conguration used for the MPS1 amplier channels, proper connection of each
speaker is essential. The 5-way binding posts can
accept bare wire, spade terminals, and dual or
single banana connectors. Spade connections or
banana plugs ensure a simple, solid t in the terminal whereas bare wire may be awkward when the
terminal is screwed down to compress the wire into
place. Keep in mind that if you use “dual banana”
plugs and “stack” them, you will be creating a parallel connection.
Spade connections ensure a tidy and safe connection
to each speaker output binding post.

Page 25
Series and Parallel Speaker Connections
Whenever connecting more than one speaker per channel to an amplier (regardless of the brand),
you must consider the way in which the amplier will be impacted by adding the additional
speaker(s). Additionally, speakers with dual voice coils also apply to this consideration. Two voice
coils in a single speaker also cause dierent reactions from an amplier depending on the way in
which they connect to the amplier.
The connection of more than one speaker per channel will tend to degrade the speaker’s frequency
response and may make the amplier run hot. For the best sonic results, use one speaker per amplier channel. If you must connect more than one speaker per channel, there are two methods in
which to do so: Series or Parallel.
Series
A series connection is established when voice coils are connected in a string – end to end – so
there’s only one way for audio signals to ow “in” and only one way for audio signals to ow “out”.
For example, if you were to series-connect two speakers
to the front right channel of the amplier:
• The positive output terminal of the right channel connects
to the positive input post of the rst speaker.
• The negative input post of the rst speaker connects to the
positive input post of the second speaker.
• The negative input post of the second speaker connects to
the negative output terminal of the right channel.
The total impedance of speakers in series is found by
adding their impedances together. For example, two
four ohm speakers in series is an eight ohm load. Series
connections are easier on the amplier than parallel connections as the total impedance is higher than driving a
single speaker.
An example of a SERIES connection
between two speakers
Page 24
Parallel
A parallel circuit is established when voice coils are connected in a way that there are multiple
paths for audio signals to ow “in” and multiple paths for audio signals to ow “out”. When speakers
are connected in parallel, the total resistance at the amplier is proportionally divided based on
the value of each individual voice coil resistance. The term “divided” simply means all of the values
together in parallel are a SMALLER value than each all by itself. For example, if you were to parallelconnect two speakers to the front right channel of the amplier:
• The positive output terminal of the right channel connects to
the positive input post of the rst speaker and to the positive
post of the second speaker.
• The negative output terminal of the right channel connects to
the negative input post of the rst speaker and to the negative
post of the second speaker.
The total impedance of equal speakers in parallel is found
by dividing the impedance of one speaker by the number of
speakers. For example, two eight ohm speakers in parallel is
a four ohm load (eight ohms divided by two), four eight ohm
speakers in parallel is a two ohm load (eight ohms divided
by four).
Parallel connections are harder on the amplier than series
connections, as the total impedance is lower compared to
An example of a PARALLEL
connection between two speakers
driving a single speaker, and the amplier must produce
more current to drive them.
Ideally, the total average impedance should be no less than 2 ohms per channel. You must make
sure that the lower impedance does not cause the amplier to overheat, shut down, blow the line
fuse, or pop your circuit breaker. If this happens, you should reduce the number of speakers wired
in parallel, rewire them in series, or use more than one power amplier.
Technical Note about Multiple Speaker Connections
Although there are two possible connection types discussed in this manual, it is imperative that
with either connection type that you use loudspeakers of the same type and nominal impedance for
these connections. In doing so, you have the most predictable outcome for your installation. When
speakers of dierent nominal impedances and/or dierent bandwidths are used, there are many
other acoustic problems that come into play in addition to complex impedance at the amplier’s
speaker output terminals. If you must use multiple speakers on any individual amplier channel,
please use speakers as close to identical as possible.

Speaker Placement Tips
Tips Before You Begin
Read this section thoroughly. There are a number of ways in which it may seem aesthetically pleasing
to place speakers in a room that will ultimately result in a sound quality compromise. The placement
of speakers is equally as important as the room itself. While there may be very little you can do about
the room where your home theater is installed, you can choose placement of speakers within that
room to maximize the sound quality of the system. Ultimately, this will give a much better result
when you are enjoying your home theater and your new Emotiva MPS-1.
Overall, the best placement for front speakers is where the sound is directed at ear level. This means
that the speakers themselves can be in positions lower (like small oor standing speakers) or higher
(like in-wall or in-ceiling speakers) as long as the sound is “pointed” toward the listeners and preferably around ear level. This is not necessarily the case with the rear speakers or the side axis speakers.
Read each of the sections carefully for the most appropriate positioning. A subwoofer is also a little
challenging to install depending on the room. In multiple subwoofer installations, the positioning
of the woofers to the listener as well as to each other is critical because there can be problems with
cancellation if optimum placement is not observed.
Page 26
The Front Speakers
You should closely follow the placement recommendations
of your speaker manufacturer, with the addition of the following points:
• The left and right front speakers should be positioned so that
your TV is exactly centered between them. This will help focus
your attention towards the screen.
• For the best overall imaging, the left speaker should be set
exactly the same distance and angle away from your listening
Place LEFT, CENTER, and RIGHT main
speakers at equal distances from the
listening position.
position as the right speaker. It is recommended that you use
a tape measure to set them up to be the same distance away,
within about half an inch tolerance.
If you have a smaller TV, the speakers should be no more than two feet away from the sides of the
TV. If possible, have the center, left and right speakers at the same height (within two feet). This will
help give a smooth transition when sound eects move from speaker to speaker.
Ideally, the speakers should be no closer than two feet from the rear and side walls, in order to reduce
any reections that might upset the imaging. If your speakers are closer than this, you can experiment by adding sound deadening material such as drapes on the walls to reduce any unwanted
reections.
The Center Speaker
Most movie dialog will come from the center speaker, so
careful positioning is an important part of a good home
theater system. Your eyes and ears should focus your attention towards the center of the screen.
The center speaker can sit on top, or directly underneath
the TV, as long as it is located on the centerline and not o
to one side. Ideally you would try to maintain a deviation
from the center line of the speakers of less than 12”. This
means the center speaker will not be lower or higher than
Whenever possible, place the center
speaker no more than 12” (25.4cm) above
or below the front speakers
12” to the center measurement of the LEFT and RIGHT MAIN
speaker center measurements.
Position the front face of the speaker close to the front edge of the TV cabinet. (The sound waves
may otherwise reect o the top of the TV cabinet and distort the center imaging).
In some systems, two center speakers are used; one on either side of the TV. As they are in mono,
the result is a sound image that is positioned exactly at the screen center.
Page 27
Page 29
Side-Axis Speakers
Some preamplier processors feature side-axis
channels which are matrixed and derived from
the left and right front channels, so they are
available in stereo as well as surround modes. If
available as a feature, the processor should have
a set-up menu to turn the SIDE-AXIS channels
ON or OFF.
In the diagram to the left, typical placement of
side-axis speakers is depicted by the speakers that
appear to be “suspended” where walls are in the
Potential Side Axis Speaker Locations
room. Another appears above the window on the
left side of the drawing. Wherever you position
them, place these speakers along the side walls, close to the fronts. You can also angle them in towards
your listening position for better results. You should not use a surround or eect speaker (such as a
dipole) for side axis speakers. Direct radiating speakers will give the best result without interfering
with the clarity and presence of the main speakers in the front left, center, and right sides.
The Surround Speakers
Place each surround speaker to be an equal
distance away from your central listening position and keep them at least one or two feet
above ear level.
Dipole

Locations
The diagram to the left shows the use of dipole

null zone (the “apex” of the triangular shape)
which should point towards the listener. The
overall eect is that you cannot hear the direct
sound from the surround speakers because
they don’t directly radiate into the listening space. Most manufacturers of dipole speakers intended
for use as an eects or surround speaker have excellent details on optimum positioning for the best
overall results based on the application.
Conventional surround speakers can be placed behind the listener, on the rear walls or the side
walls or in the ceiling (as the diagram indicates). Adjust the angle so they do not point directly at
the listener but cause reections from the sidewalls, oor, or the ceiling. Avoiding direct aim at the
listening positions will give the eect of broadening the rear soundstage so that you cannot distinguish the sound as coming from a small box on the wall but from a larger area behind you.
Page 28
Surround Back Speakers
Many preamplier processors feature additional outputs for surround back speakers. These create a
wonderful sense of realism in surround eects during playback of Dolby Digital EX, Dolby Pro Logic
IIx, and DTS ES.
Ideally, all the surround speakers should be of the same make and model as the surround speakers,
and tted at similar heights to produce a smooth continuous sound eld.
Subwoofer Location
Although subwoofers are normally congured with their
own internal power amplier (rather than using the MPS-
1), we know you will probably use at least one subwoofer
in your home entertainment system. As such, it’s important
to understand correct subwoofer placement so that you get
the most out of the other speakers connected to the MPS-1
Modular Power Amplier.
A subwoofer typically sounds best in a corner with at least
5 feet of wall to either side. Due to the short wavelengths
of high-frequency sounds, they don’t interact strongly with
Standing waves depicted in a room.
“Peaks” are good, “Dips” are bad.
the size and shape of a room. Lower frequencies long wavelengths that can cause “Standing wave” problems. Placing
the subwoofer in a corner usually creates the best possible
situation for the sound to interact with the room, allowing
even distribution of the bass frequencies. Often the corner that oers nearby placement to the
front speakers may yield the best results, but you should try several locations before settling on
just one.
The best location for a single subwoofer can be found by playing a couple of dierent low frequency
test tones (or some music with heavy sustained bass passages) and proceeding with the following
easy 1-2-3 process:
1. Place the subwoofer right on the seat of your couch or listening chair.
2. You can then either run the calibration (noise) signal through it, or simply plug the analog outputs of a
CD player directly into your subwoofer’s low-level inputs. Turn down the subwoofer’s volume level before
turning on the CD, then play the test tones or some music with heavy sustained bass passages.
3. Walk around the room, standing in all the positions where you might be able to place the subwoofer.
Again, this is usually near the corners of the room. Try locations fairly close to the front speakers.

Walk around the room and see
where the bass has the best
performance. That’s where your
subwoofer belongs!
Notice where in the room the bass output from the subwoofer sounds the loudest. Shut things down
and install the subwoofer there. This is the best position for the subwoofer. The bass will sound the
best when you are sitting in your normal listening position.
If your subwoofer seems to sound best when it is near the front speakers (often the case), keep in
mind that most television sets may not react well to the subwoofer if it is not built specically for use
in a home theater application. While most front Left/Center/Right speakers do have shielding when
intended for use in a home theater application, subwoofers are not always magnetically shielded
and may damage the television if placed too close. If you want to check if this will be a problem,
select an unused video input on the television to bring up a single color screen. If you see any color
distortion anywhere on the screen, an unshielded speaker is too close to the screen and should be
moved away from the television until the color distortion disappears.
Note - most powered home subwoofers feature a phase control with a range between 0-180 degrees. This
is present so that in situations where the optimum location is not particularly desirable, you can locate
the subwoofer elsewhere nearby and make a slight adjustment to the phase so that is sound arrives to
the listener at the same time as the other speakers. Ideally, sound arriving at the same time is what allows the subwoofer to create the illusion of the main speakers making the bass. This is what enhances
the listening experience.

Troubleshooting Guide
The Emotiva MPS-1 is expertly designed and built to provide years of trouble-free performance. Most
problems that occur can usually be solved by checking your setup or making sure that the audio
and video components connected to the amplier are on and fully operational.
The following information will help you deal with common setup problems you may experience
during normal use of your unit. If problems persist, contact your Emotiva Dealer for help.
No Sound (from one or more speakers connected to the MPS-1)
• Speaker cables may have come undone. Turn o your system and check the cables, and tighten the
amplier and speaker binding posts.
• Damaged audio cable.
• The preamplier volume level is low for the channels concerned. Recheck the preamplier calibration
procedure.
• A preamplier Mute switch may be on, or an external processor loop or a tape monitor loop is engaged.
• Check that your preamplier or source is running the correct surround sound mode. Maybe it is set for
2-channel stereo when you were expecting 5.1 surround sound.
• Check in case any missing channels have been turned o in a preamplier setup menu. For example, the
center amplier channel will not receive a signal if the preamplier has been set to “Phantom.”
• The Auto/on/o switch on the MPS-1 might be in the o position.
• A fuse on the unit may have blown or the individual fuse within the power module may have blown.
The amplier shuts down often or the line fuse(s) blows often
• Check that the positive and negative speaker wires are not shorted together.
• Make sure that no speakers are shorted internally. If you have an ohm-meter, disconnect the speaker
wires and measure the resistance between the speaker’s positive and negative terminals. If the reading is less than 2 ohms, the speakers may have an internal short. Measure all speakers and check their
impedance specications.
• If you have connected speakers in parallel, the overall impedance may be too low. It is recommended
that you rearrange the speakers in series to increase the overall impedance, thus taking some of the
load o the amplier.
• Make sure that the amplier has good ventilation and is not overheating. Allow good airow underneath wherever possible. If the amplier is in a closed rack, open up the rear panel or use a quiet fan
for improved ventilation.
Poor Bass Performance From Full Range Speakers connected to the MPS-1
• Make sure that your preamp does not have the bass (tone control) level turned down.
• Many surround preampliers have controls which can direct all the bass to subwoofers, or let your main
Page 31
Page 33
speakers play the full range. Make sure that the preamplier has been correctly set. If you are not using
a subwoofer, set the speaker options to “Large” where possible.
• Check that the speaker wires have been connected correctly: Make sure that the positive of each speaker
connects to a positive output of the amplier, and the negative of each speaker connects to a negative output. If one speaker is wired incorrectly, than it will be “out of phase” with the others, resulting
in poor bass performance.
• If you have connected the amplier using the XLR inputs, make sure that the XLR cables are wired correctly. If one has the hot and cold reversed (pins #2 and #3), then this will also cause a speaker to be
out of phase.
Turn-on and turn-off thumps
• Plug the amplier into an un-switched AC outlet, and use the SIGNAL position of the turn on switch at
the back of the amplier. This will allow the amplier to turn on and o silently.
“Hum” Noises in the Speakers
This problem is more than likely caused by a “ground loop” in your system, rather than a fault in the
MPS-1. Follow these steps to isolate the main cause of the hum, there may even be more than one.
Remember to turn o all components in your system, including the MPS-1, before disconnecting
or connecting any cables.
• If your preamplier has XLR balanced outputs, use them because they oer greater immunity to noise
elds.
• Remember to turn o all components in your system, including the amplier, before disconnecting or
connecting any cables during troubleshooting.
• Try to have all of your equipment on the same electrical outlet or circuit. Group all the low power components (preamp, CD player, DVD etc.) on a single outlet or power strip. This is provided that the overall
current draw from your equipment does not exceed the rating of the outlet or breaker.
• Disconnect all cables which come from outside the room, and check if the hum goes away. This includes
such connections as cable TV, satellite TV, or roof top antennas. Make sure that they are disconnected
where they rst enter the room, so they are making no connection to the preamplier or the TV, or any
other component. If the hum is caused by the cable TV line, then you will need a “ground loop isolator.”
This is an inexpensive device tted in line with the coaxial cable feed. Contact your cable company or
your Emotiva Dealer (unless purchased through AV123) for assistance.
• Disconnect all connections from the preamplier to your TV, VCR or DVD.
• As a test, disconnect any other component which has a grounded power cord.
NOTE: Never remove the ground pin from any power cords (if present). This is very dangerous.
• If the hum persists, disconnect all the source components one at a time from the back of the preamplier, until you identify the problem.
• Try moving the speaker cables away from any power cords. Try just one speaker, connecting it to each
amplier channel and see if one channel is bad.
Page 32
• Check that the interconnect cables to the amplier do not have any broken connections. The best
way to do this is to substitute a known good connection for the suspect connection. If you reverse the
cables and the problem goes away, the cable may be damaged or broken. This is possible even if you
can’t physically see the break as the strain for pulling on audio cables can sometimes break the wire
internally.
Ground loop isolators are available for audio lines and video devices. You can ask your Emotiva
Dealer for assistance. Although this is not always an ideal solution, the grounding dierences between certain home entertainment components sometimes require ground loop isolators. This is
the exception rather than the rule.
Other Probable Causes of Noise
Speaker noise may also be caused by interference or noise on your AC line. Make sure there are no
large appliances sharing the line, or halogen lamps or light-dimming Triac devices.
Try connecting your system to another AC socket on a separate line.
If the hum is heard from within the MPS-1 and not through the speakers, this may also be caused by
interference on the AC or DC lines. The power transformers may turn this interference into an audible
noise. Internal hum can be made worse by a shelf or cabinet resonating, so try moving the MPS-1 to
another shelf.
Try moving your components further away from the TV, especially if you ever notice the screen has changed
color in the area closest to the component.
If you have very high eciency speakers, these may tend to reveal noises which other speakers do
not.
One or more RED lights on the Front Panel are On
Each RED light indicates a fault condition for the corresponding power module. A fault condition is
one or more of the following:
• Excessive Operating Temp
• Excessive Current (Short Circuit)
• DC on the Outputs
An excessive temperature fault can be reset by allowing amp to cool and cycling power on/o button on the front panel. Excessive current (short circuit) can be reset by removing the cause of the
short and cycling power on/o button on the front panel. DC at output is a possible fault condition that is equipment related and requires technical assistance. Please contact AV123 if you have
repeated problems causing the RED front panel light to illuminate that are NOT thermal or short
circuit related.
