CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No
user serviceable parts inside. Refer to qualified personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to
rain or moisture.
The lightning flash with arrowhead, with­in an equilateral triangle, is
intended to alert the user to the presence of uninsu­lated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to
constitute a risk of electrical shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating maintenance (servicing)
instructions in the literature accompanying the appliance.
Precautions
Verify The Line Voltage
Your new Powered Subwoofer has been factory configured for 120 volt AC lines. Connecting
an M8 to a line voltage other than that for which it is intended can create a safety and
fire hazard, and may damage the subwoofer. If you have any questions about the voltage
requirements for your specific model, or about the line voltage in your area, contact Outlaw
Audio before plugging the unit into a wall outlet.
Verify AC Circuit Capacity
The high power output of your Outlaw M8 may require heavy power draw under full load
conditions. To insure proper performance, and to avoid potential safety hazards, we recommend that it be connected to a 20 Amp capacity circuit. Connecting multiple subwoofers
to the same circuit, or connecting it to a circuit used by other heavy power devices, such as
air conditioners, may cause circuit breakers to trip.
Do Not Open The Cabinet
There are no user serviceable components inside this product. Opening the cabinet may
present a shock hazard, and any modification to the product will void your guarantee. If
water or any metal object, such as a paper clip, coin or a staple, accidentally falls inside
the unit, disconnect it from the AC power source immediately, and contact Outlaw Audio
for further instructions.
FCC Information for User
CAUTION: ANY changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
IMPORTANT SAFETY NOTE
Before connecting a new component such as the M8 to your audio or home theater system
it is always good practice to make certain that all components are turned off, and preferably
unplugged from their AC power source. Many modern electronics products feature automatic
turn-on circuits that may be activated during an installation, causing the potential for
damage to electronic components and/or speakers. Such damage is not covered by product
warranties and Outlaw Audio specifically disclaims responsibility for any such damage.
NOTE: It is always a good idea to avoid using any audio or video equipment
on the same AC circuit as equipment with motors, such as air conditioners or
refrigerators. This will lessen the possibility of power variation and electrical
start-up noise affecting your sound system.
Extension Cords and Power Strips
We do not recommend that extension cords be used with this product unless they are of
sufficient gauge to pass the necessary current during full load conditions. Most inexpensive
extension cords are not capable of such high-current loads.
Similarly, should you use a power strip, surge protector or any type of AC power line conditioning equipment, make certain that it is also able to handle the high current loads
this product will produce.
Handle the AC Power Cord Gently
When disconnecting the power cord from an AC outlet, always pull the plug, never pull the
cord. If you do not intend to use the amplifier for any considerable length of time, disconnect
the plug from the AC outlet. If the power cord is replaced, make certain that it is of similar
gauge. As with all electrical devices, do not run power cords under rugs or carpets or place
heavy objects on them. Damaged power cords should be replaced immediately with cords
meeting factory specifications.
Wiring
Cables that are run inside of walls should have the appropriate markings to indicate complaince with, and listing by the UL , CSA or other standards required by the UL, CSA, NEC or
your local building. Questions about cables inside of walls should be referred to a qualified
customer installer, or a licensed electrician or low-voltage contractor.

Subwoofers, Bass and Overall System Performance
Subwoofers, Bass and Overall
System Performance
The goal of an audio system is to recreate the source material as accurately as
possible. The components needed to perform this task are an audio source, a
receiver or processor/amplifier combination, and speakers.
In the era of digital, multi-channel sound, many listeners have chosen to use
frequency-limited “satellite” speakers for the front, center and surround channels.
By limiting their frequency range, these speakers may be made smaller, to more
easily fit into a wide range of spaces. However, by eliminating the capability to
reproduce bass frequencies, a separate speaker that is custom designed to deal
with signals below 200Hz is required. That speaker, along with its companion,
built-in amplifier is a powered subwoofer.
Even in two-channel systems with traditional bookshelf or tower speakers the
bottom two octaves of sound (20 Hz to 80 Hz) are frequently rolled off or not
reproduced at all. Here, too, a specialized speaker/amplifier combination is
required to deliver the full spectrum of sound from a system.
Finally, many multi-channel digital soundtracks contain a special audio channel
devoted specifically to extreme low frequency extension. This signal is the “.1” in
5.1, 6.1 and 7.1 systems and is sometimes referred to as the LFE channel.
Regardless of which of these situations create the need, a subwoofer is absolutely
essential for accurate audio reproduction of both movies and music. A properly
designed subwoofer such as the Outlaw M8 can provide a visceral impact that most
speakers are not able to provide on their own. No matter what type of speakers
comprise the rest of your system or what your favorite movie or music is the M8 is
up to the task of completing the sonic presentation by providing the impact that
only a subwoofer can provide.

To get the maximum performance from your new M8 it must be properly connected, positioned properly within the room and configured to match your speakers. To connect the M8 you will need either a single audio interconnect cable (in
the case of systems with a subwoofer output), a pair of audio interconnects (in the
case of systems without a left/right pre-amp output) or additional speaker wire.
We recommend the Outlaw Audio PCA SUB cable, but any high quality, shielded
audio interconnect will work properly.
AC INPUT
Connect your power cord here.
1. Turn off all system components and unplug the processor or receiver
and the M8 from their AC power source.
2. Locate the “Subwoofer/LFE Output“ on the rear panel of your receiver
or processor.
Any audio product that decodes Dolby Digital or DTS soundtracks will have
this type of jack. Depending on the particular brand or model, this RCA jack
may be labeled “Sub”, “Subwoofer”, or “LFE Out”. If your receiver or processor does not have this type of output you will need to follow the “Connecting
to a System with No Preamp Outputs“ instructions that follow this section.

Preamp Output, but with Standard Left/Right
Preamp Outputs
If your system does not have a dedicated subwoofer preamp output, but has left/right
preamp outputs, you can use these jacks to connect your receiver or processor to the
subwoofer amplifier. See Diagram 2 on the next page.
To connect an M8 Subwoofer using standard Left/Right preamp outputs:
1. Turn off all system components and unplug the processor or receiver
and the M8 from their AC power source.
2. Locate the “Left/Right preamp outputs” on the rear panel of your
receiver or processor.
Some audio products that do not offer digital surround processing will
have these types of jacks. If your receiver or processor does not have this
type of output you will need to follow the “Connecting to a system with no
pre-amp outputs” instructions that follow this section.
3. If using an external power amplifier; connect a Y-Adapter/Splitter to the
left and the right pre-amp outputs (one for each output). If a separate
amplifier is not being used, connect a pair of RCA cables to the left and
right preamp output and skip ahead to Step 5.
4. Connect one set of the pre-amp outputs created by the Y-Adapters/
Splitters directly to your power amplifier with a pair of RCA cables.
5. Locate the connections labeled “Right” and “L/MONO” on the rear
panel of the M8.
6. Connect the remaining pre-amp output connections to the “RIGHT”
and “L/MONO” connections on your M8 with a pair of RCA cables.
7. Plug the M8’s power cord into an un-switched AC outlet.
CAUTION: Due to the power requirements of the M8, it must not
be connected to the accessory outlets on a receiver or processor. If a
power-strip or surge protector is used, make certain that it is rated to
accommodate the M8’s power requirements.
8. Reconnect your processor or receiver to the AC power source.
9. Proceed to the “Setting the M8’s Controls” section to learn about the
M8’s controls and how they operate.

Outlaw Audio
To connect the M8 Subwoofer using high level inputs:
1. Turn off all system components and unplug the receiver and/or amplifier
and the M8 from their AC power source.
2. Locate the front left/right speaker output terminals on your receiver or
amplifier.
In cases where there are both “A” and “B” terminals, the “A” terminals should
be used. Disconnect any wire that is presently connected to these terminals.
3. Using the same type of speaker wire used for your other speaker
connections; connect the left and right channel speaker outputs of your
receiver or amplifier to the M8’s “Speaker Level Input”.
NOTE: Be sure to connect the speaker wires to the appropriate speaker
input connections located on the back of the M8, making certain that
the polarity (–/+) on the receiver or amplifier matches the polarity on
the connections of the subwoofer amplifier. In most cases this means
connecting the red terminal on the receiver or amplifier to the red
terminal on the M8, but always check the markings on the rear panel
to insure “+ to +” and “– to –“ connections.
4. Plug the M8’s power cord into an un-switched AC outlet.
CAUTION: Due to the power requirements of the M8, it must not
be connected to the accessory outlets on a receiver or processor. If a
power-strip or surge protector is used, make certain that it is rated to
accommodate the M8’s power requirements.
5. Reconnect your receiver and/or amplifier to the AC power source.
6. Proceed to the “Setting The M8’s Controls” section to learn about the
M8’s controls and how they operate.
Subwoofer Placement
Placement of your subwoofer is a critical component in maximizing the performance of your M8. Placement influences the subwoofer’s “perceived” frequency
response, sound pressure level (SPL), and overall accuracy. Since each listening
room differs in virtually every aspect, the ideal location will also vary.
An easy way to find the right spot to place your new M8 is to experiment with what
we call the “Subwoofer Switch Trick.” This process puts the subwoofer where you
normally sit and then lets you play the role of the subwoofer.
1.Place the subwoofer as close to your favorite listening position as possible. If
possible, place the unit in front of your couch or easy chair, right in the room’s
“sweet spot.” Provided that there is no damage to your furniture, you may even
place the subwoofer on the chair or couch, but remember that the M8 is heavy,
and the Outlaws are not responsible for any damage to your furniture or for
arguments this might cause with other members of the household!
2. Activate the test tone from your processor or receiver’s internal test tone generator,
or use your favorite test disc so that pink noise plays through the subwoofer. While
the test tone is playing, walk around your room to find the spots where you hear
the best bass response. Sometimes this may be in the center of the room, while
in other cases you may find the best spot in a corner or along a side wall.
3.Turn off the test tone and move the subwoofer to the location where you hear
the best bass response. If that location is unacceptable or impractical, repeat
the procedure to the spot that is the best compromise between bass performance
and aesthetic considerations.

Setting the M8’s Controls
Notes On Subwoofer Placement
Volume Level
Try to avoid creating a listening position that falls directly between the front
and back walls as this may cause a strong interference effect due to the collision
between bass waves bouncing off the rear wall and new bass waves from the M8.
When this happens you might hear an unnatural “build up” in the low frequencies
where the bass sounds “bloated”, based on the specific dimensions of the room
and the particular frequency being reproduced.
Using the built-in test tones of your receiver/processor, match the levels of all
of your speakers including the M8 as described in your receiver or processor’s
owner’s manual. A setting of 5 on the M8’s volume knob should provide enough
gain to properly match the sub level to your speakers. We recommend using an
SPL meter such as the Radio Shack (part number 33-2050). When using the test
tones, measure from the listening chair and set the meter to the 75 dB level. In
order to accurately measure levels between channels use “C” weighting and the
“slow” setting.
In other situations you might encounter a “null”, which is caused by two low
frequency waves canceling each other out. When this happens you will find that
your favorite listening position is bass shy. In this type of placement situation bass
response will suffer greatly regardless of how powerful the subwoofer is. The best
way to solve this problem is to change the location of the seating position so that
the distance to the front of the room is different than that to the back of the room.
Setting the M8’s Controls
Phase Switch
Depending on the absolute phase of your main speakers and amplifier, as well
as the relative distance from the M8 and main speakers to the listening position,
the bass in the crossover region may be smoother if you reverse the phase of the
M8. Try both positions of the phase switch to determine which way sounds more
bass-heavy. The bass-heavier position is the setting where the output of the M8
and the main speakers are most in phase. Use program materials with bass in
the crossover region such as music containing bass drums, double basses, bass
guitar, etc. to determine the correct setting.
Variable Crossover
By adjusting the variable crossover on the M8, you can perfectly match it to your
main speakers. If your receiver or processor already has a built in crossover, disable
the crossover on the M8 by flipping the X-over switch to the “BYPASS” position.
Refer to the owner’s manual for your receiver or processor to see how to disable
any internal crossover capability it may have. If your receiver or processor does not
have internal crossover control, follow these steps to set M8’s variable crossover:
Determine the +/- 3dB point of your main speakers. This frequency is usually
found on the speaker’s specifications sheet or may often be available on the speaker
manufacturer’s web site. Start with the crossover set approximately to this point. By
experimenting with the crossover frequency and level control, you can fine-tune
the M8 so that there is a seamless link between the M8 and the main speakers.
If the actual +/- 3dB point cannot be obtained from the speakers’ specifications
or the manufacturer’s web site, you can use the following chart as a guideline:
40 Hz
Large tower speaker with one 12 or 15-in. woofer or two 10-in. woofers;
Small tower speaker with one 10-inch woofer or two 8-inch woofers
60 Hz

Note: The Radio Shack meter is down about 12 dB at 16 Hz, 7 dB at 20
Hz, and 4 dB at 25 Hz. Add these numbers to the readout to compensate
for these errors if necessary.
The Scattered Subwoofer System (Two M8’s)
Why Two Subwoofers?
In most circumstances two subwoofers will perform better than one. While you
might assume this is for added SPL, the greatest benefit will actually be smoother
bass response.
Room shape, the cubic volume of the room (width x depth x height), furniture,
floor coverings and even wall and ceiling material all play a roll in bass performance. These factors create peaks and dips in the level of low frequencies at
different points in the room. That said, two properly positioned subwoofers will
distribute the bass throughout the room with greater accuracy than a single sub.
For this reason many professional acousticians and installers recommend more
than one subwoofer. The final result is that you will create a much larger “sweet
spot” where the bass is powerful but more importantly smooth and consistent.
If near perfect bass response is your goal, consider using two M8’s: the Outlaw
Audio Scattered Subwoofer System.
What’s Needed to Connect Two Subwoofers?
Most of today’s digital receivers and pre-amp/processors provide a single subwoofer
output. Connecting two subwoofers to these systems is as simple as adding a Yadapter. A Y-adapter splits a single output into two separate outputs. Be sure to
use a Y-adapter that is of equal or better quality than the subwoofer cables you
intend to use.
To use the Y-adapter, insert the single male end of the cable to the subwoofer
output of your receiver or processor. On the opposite end of the Y-adapter you will
now have two separate subwoofer outputs, one for each sub.
Placement and Level Control
Placement and level control of two subwoofers is somewhat more complicated
than using a single subwoofer. However, the end result of two properly placed and
calibrated subwoofers is well worth the added effort.
The procedure for placement of the second subwoofer is identical to that of determining the placement of the first subwoofer (see the “Subwoofer Placement”
section of this manual). However, the second sub should be placed in the seating
area outside of the “sweet spot” where good bass response is also required. Walk
around the room until you find the area where the bass sounds the best, just as
described in the process for locating a single sub. This spot will almost always be
different than the one that was best for the primary sub.

Troubleshooting
NOTE: When calibrating your second subwoofer, be sure to turn off the first
sub. This will help you to determine ideal placement without being misled
by the response of the first sub.
Humming or
Buzzing Noise
When calibrating the final levels of each subwoofer, you may want to reduce
their output to compensate for the added 3 or 4 dB of gain created by using two
subwoofers together.
If you sense a loss of bass output after properly locating and calibrating both
units in a two-subwoofer system, the likely problem is that the two units are out
of phase with each other. If this occurs try flipping the phase switch on the back
of one or both of the subwoofers until the bass returns. For more information
regarding the phase control function, please read the “Setting the M8’s Controls”
section of this manual.
Care and Maintenance
Cleaning
When the M8 Subwoofer cabinet becomes dirty, wipe it with a clean, soft, dry
cloth. If necessary, first wipe the surface with a soft cloth slightly dampened with
mild soapy water, then with a fresh cloth dampened with clean water. Wipe dry
immediately with a dry cloth.
NEVER use benzene, thinner, alcohol or any other volatile cleaning agent. Do not
use abrasive cleaners, as they may damage the finish of the metal parts. Avoid
spraying insecticide, waxes, polishing agents, or any aerosol product near the unit.
If the hum goes away when interconnects are
disconnected, it is coming from the rest of your
equipment. Add them back one piece at a time.
The one that causes the system to hum is the
source of the noise.
No output from the
subwoofer (The LED
does not light up)
On the back of the subwoofer, make sure the
power switch is set to “on” or “auto”, and the
power cord is fully inserted and receiving power.
The subwoofer is
not receiving a
signal (The red light
does not turn green)
Recheck the connections between the receiver/
processor and the subwoofer. On the back of
the subwoofer, make sure the power switch is
set to “on” or “auto”.
No output from the
subwoofer (The LED
lights up red)
Connect the signal cable to another subwoofer
or amplifier. If you get output, then the amplifier
is faulty. Email or call technical support for
authorization to send the amplifier back for
service.
No output from the
subwoofer (The LED
lights up green)
Remove the woofer and make sure that the two
speaker wires that come from the subwoofer
amplifier are securely connected to the woofer.
If they are not, secure them or call/email
technical support for assistance.
When You Are Away
If you will not be using your home theater system for an extended period of time,
it is always a good idea to turn the unit off using the Master Power Switch on the
rear panel of the subwoofer. This will prevent the automatic turn on circuits from
accidentally powering the system on during your absence.
