INTRODUCTION
Thank you for choosing LOUD Technologies’ Mackie active sound reinforcement speakers.
The SRM350 v2 is a redesigned version of our popular
SRM350 active loudspeaker. With its newly designed Class-D
Fast-Recovery amplifiers, high-output compression driver
and new 10" neodymium woofer, it produces an even
smoother sound than the original. SRM means Sound Reinforcement Monitor, and the SRM350 v2 truly produces a
studio quality sound in a sound reinforcement speaker.
Our design goal was to build a sound reinforcement
speaker with:
1. High precision, high output, and accurate playback.
2. Very wide, smooth dispersion of mid and high frequencies.
3. Ergonomically correct physical design for easy transport
and set up.
Through the combined resources of our top-notch
mechanical and analog engineers, and our experienced
transducer engineers at EAW, we were able to achieve our
design goals in every aspect. The result is a sound reinforcement system equally at home in a concert setting, in the
studio, impromptu concerts on the studio roof, in the cinema,
or in a home theater.
The Transducers
The SRM350 v2 active speakers feature a 10-inch highpower low-frequency woofer with a neodymium magnet,
and a 1.4-inch titanium diaphragm high-output ceramic
compression driver. This high-frequency driver is mounted
on an acoustically non-resonant exponential waveguide,
providing a wide, controlled dispersion and precise
reproduction of the critical upper mid-range and high
frequencies. The result is an unbelievably smooth off-axis
response that allows everyone in the audience to experience the same high-resolution audio no matter where they
are seated.
Power Amplifiers
To power these beauties, each SRM350 v2 includes two
of our acclaimed FR Series “Fast Recovery” power amplifiers. In addition, the low-frequency amplifier uses a Class-D
design for improved efficiency and cleaner power. Our
exclusive designs use low negative feedback, yet allow the
amplifiers to maintain low distortion and stability and to
quickly recover when driven into clipping.
The amplifiers include the following features:
• The low-frequency amplifier produces 165 continuous
watts before clipping.
• The high-frequency amplifier produces 30 continuous
watts before clipping.
• When the output from either amplifier begins to clip,
a limiter gently reduces the input signal level until the
output is no longer clipping.
• The low-frequency amplifier also has a Dynamic Bass
Boost circuit. Our ears are more sensitive to bass frequencies at high volume levels than at softer volumes.
This unique circuit automatically reduces the low
frequencies below 70 Hz as the volume of the speakers goes up. This results in improved efficiency for the
low-frequency amplifier because it is not wasting power
trying to reproduce frequencies we hear better at loud
volumes. Instead, the power is used for the frequencies
where it is needed, resulting in a louder sound.
Warning: Although the amplifiers have
these protection circuits, you must
still make sure the LIMIT light is not
blinking continuously. If it is, turn
down your mixer faders, or preamplifier gain, or turn down the SRM350 v2
LEVEL control.
The Crossover
The built-in electronic crossover is a 24 dB/octave
Linkwitz-Riley design. Although more expensive than other
crossover designs, the benefits provided by the LinkwitzRiley design have been well documented. These benefits
include:
• Absolutely flat frequency response throughout the
bandpass, without the characteristic ripple near the
crossover point exhibited by other designs.
• The sharp 24 dB per octave roll-off of the filters ensures
that the transducers aren’t reproducing frequencies
outside of their capabilities.
• The acoustic sum of the two driver responses is unity
at the crossover frequency, resulting in perfect power
response.
• Our heroic engineers have worked carefully to ensure that the SRM350 v2 also provides perfect phase
response. This diligence has yielded phenomenal accuracy, even if you are standing 20 feet away.
The Cabinet
The SRM350 v2 cabinet was designed to be the strongest
molded composite cabinet on the planet. This material is as
strong as concrete, and rigid enough to prevent unwanted
vibrations in the cabinet. An optional bracket kit is available for the top and bottom of the cabinet to be used for
flying, and a socket is provided in the bottom of the cabinet
for mounting on a tripod stand. Although it is an exceptional choice for installed sound situations, its light weight and
durable finish also make it ideal for portable sound system
use. The asymmetrical trapezoidal design of the cabinet
makes it easy to use as a floor wedge for stage monitor applications.
The Active Advantage
There are a number of advantages to using an active
speaker system over a passive loudspeaker:
• The internal crossover is active, and its low power circuitry operates on line-level signals. It does not waste
speaker-level power like a passive crossover with large
coils, caps, and resistors.
• The input signals are crossed over before they reach the
amplifiers, so each amplifier only receives the correct
frequency range for its driver.
• The amplifiers are designed specifically for these
speaker load impedances. There is no guesswork as
to what load each amplifier has to drive, so they can
provide maximum acoustic output from the speakers,
yet minimize the danger of speaker damage due to
overdriving a lesser amplifier.
• The connecting wires between the amplifier outputs
and the drivers are kept to a minimum, so the damping
factor of the amplifier isn’t compromised by the resistance of long speaker cables. In addition, all the power
from the amplifier is transferred directly to the drivers
with no speaker cable losses.
• The acoustic sum of the outputs from the two drivers
is optimized electronically, as well as physically, so the
amplitude response is flat and there is no lobing error.
• The presence of active circuits within the speaker
cabinet allow the designer to add on extra details, such
as a high quality mic/line input section and optional
accessory modules.
In short, all the complex interconnected components
in the system are designed to work in harmony with each
other to produce the best possible sound.
HOOKUP DIAGRAMS
Quick Start
1. Start with the following settings on the back of the
SRM350 v2:
Turn the POWER switch off (down).
Set the CONTOUR and MIC/LINE switches out. If using
a microphone as the input to the SRM350 v2, push the
MIC/LINE switch in.
WARNING: Turn the LEVEL control
down (counterclockwise) before every
use. If not, you could be in for a startling surprise, especially if the last time
you used it was with a microphone and
now you want to connect a line-level
source.
2. Connect the output from your signal source (mixing
console, microphone, preamp, or other mic- or line-level source) directly to the INPUT connector on the back
of the SRM350 v2. This is a combination XLR and 1/4"
TRS connector, and accepts balanced or unbalanced
line-level signals from mixers, preamplifiers, CD players, tape decks, etc., with the MIC/LINE switch out, and
accepts direct connections from dynamic microphones
with the MIC/LINE switch pushed in.

3. Connect the supplied AC power cord to the IEC socket
on the back of the SRM350 v2. Plug the other end into
an AC outlet properly configured with the correct voltage for your particular model.
4. Turn on your signal source. Make sure its Master Volume control (if it has one) is turned all the way down.
5. Turn on the SRM350 v2 POWER switch.
6. Start the signal source, whether it be speaking into a
microphone or starting a CD player. Adjust any volume
controls on the signal source for normal operation.
7. Slowly turn up the LEVEL control on the back of the
SRM350 v2 until the desired volume is reached (and
the LIMIT light does not come on). Always wear hearing protectors if you are close when it is playing at high
levels.
8. If there is no sound, always turn down the SRM350 v2
LEVEL control before investigating. There may be a
mixer or preamplifier mute or tape switch engaged, or a
mic switch off.

SRM350 v2: Daisy-CHaining using THE THRU JACK
The SRM350 v2 can
be used with a Mackie
SWA1501 (or SWA1801z or
SWA2801z) subwoofer to
create an incredibly powerful system.
The active crossover
inside the subwoofer splits
the full range input signal into two ranges. The
subwoofer plays the low
frequency range through
its built-in amplifier and
woofer, and sends the
high-pass range to the
SRM350 v2.
The SRM350 v2 can
be pole mounted on top
of the SWA1501 as shown
using the optional SPM100
Speaker Pole Mount,
saving the cost of a more
expensive tripod stand.

SRM350 v2: 3-Way System WITH A POWERED SUBWOOFER
REAR PANEL DESCRIPTION
3. POWER Indicator
The SRM350 v2 has several connectors, controls, and
indicators that you should understand.
When the POWER switch is turned on, and the linecord
is connected to an active AC Mains supply, this indicator, located just above the POWER switch, glows to let you know
that you’re ready to rock and roll. The cool blue LED on the
front of the speaker works in the same way.
1. IEC Socket
This is where you connect the supplied AC linecord to
provide AC power to the SRM350 v2’s built-in power amplifiers. Plug the linecord into an AC socket properly configured
for your particular model.
Note: If you happen to lose the AC linecord, replacements are readily available at any office or computer supply
store. Always use a three-pin plug with a ground pin.
4. CONTOUR
Pushing in this switch engages a filter that provides 3 dB
of boost to the low and high frequencies (below 100 Hz
and above 12 kHz). This provides a punchy, crisp sound
for most live music applications. You can experiment with
this switch by leaving it out for a while, then pushing it in
to determine which way sounds best for your application.
It is especially useful when listening at lower volumes, as
it highlights the bass like a Loudness switch, in addition to
boosting the highs.
2. POWER Switch
Switch up to turn the SRM350 v2 on, and switch down to
turn it off. Make sure the LEVEL control is down before you
turn it on.
5. LEVEL
THIS DEVICE COMPLIES WITH PART 15

SIGNAL
This is used to adjust the signal
level, going into the built-in power
amplifiers, from Off up to 45 dB
of gain. Since the SRM350 v2 incorporates Mackie’s world-class
low-noise mic preamp technology,
you can connect either a line-level
or a microphone-level signal to
the input, and use this control to
adjust the level correctly.

There is no
phantom power provided for
a microphone,
so you should
use a dynamic
mic, or use a condensor type if it
has its own battery power.
Follow the Quick Start guide on
page 6 for setting the LEVEL control. For most applications, it will
be in the NORMAL position (12
o’clock). If you have a particularly
high line-level signal connected
to the SRM350 v2, you may need
to turn the control down to the 9
o’clock position. If you have a low
line-level or mic-level signal connected, you may need to turn the
LEVEL control up to the 3 o’clock
position.
6. MIC/LINE Switch
Leave this switch out when connecting a line-level signal
to the INPUT connector (from a mixer, graphic EQ, or other
line-level signal source).
Push this switch in when connecting a microphone
to the INPUT connector. Since a microphone produces a
much smaller signal than a line-level signal, this provides
an additional 40 dB of gain to boost the microphone signal
to a line level.
7. SIGNAL Indicator
This LED illuminates whenever there is a signal present
at the INPUT connector on the rear panel. It senses the
signal just after the LEVEL control, so if the LEVEL control
is turned down, the SIGNAL indicator won’t light.
It’s okay for the LIMIT indicator to blink occasionally,
but if it blinks frequently or continuously, either turn down
the signal level at the mixer or other signal source, or turn
down the SRM350 v2’s LEVEL control.
Wear hearing protection if you are close
to the SRM350 v2 playing at high levels.
9. INPUT Connector
This is a combination female XLR-type and 1/4" TRS
connector that accepts a balanced or unbalanced mic- or
line-level signal.
8. LIMIT Indicator
10. THRU Connector
When the signal levels at the amplifier outputs approach
clipping, a soft limiting circuit is activated that reduces
the input signal. The LIMIT LED lights whenever the limit
circuit is active.
This is a male XLR-type connector that can be used to
daisy-chain the input signal to another speaker.
The signal at this point is after the MIC/LINE switch but
before the LEVEL control. If you have a microphone connected to the first SRM350 v2 and you have the MIC/LINE
switch pushed in, the signal at the THRU jack is boosted
40 dB to a line-level, so leave the MIC/LINE switch out on
the next SRM350 v2.

CONNECTIONS
PLACEMENT
The SRM350 v2 has a combination female XLR and 1/4"
TRS input that accepts a balanced or unbalanced mic- or
line-level signal. When connecting a balanced signal, be
sure it’s wired per AES (Audio Engineering Society) standards:
XLR TRS
Hot (+)
Pin 2 Tip
Cold (–)
Pin 3 Ring
Shield (Ground)
Pin 1 Shield
The SRM350 v2 active speakers are designed to sit on
the floor, a tabletop, or to fit on a standard tripod speaker
stand. They can also be suspended by the rigging points,
which requires installing the optional hanging bracket on
the top and/or bottom of the cabinet (SRM350 Bracket Kit:
Part No. 0016404). NEVER attempt to suspend the SRM350 v2
active speakers by their handles.
You can lay the cabinet down on its side and use the
SRM350 v2 as a floor monitor. The asymmetrical trapezoidal
shape of the cabinet provides a perfect angle for aiming up
toward performers from the front of the stage.
There is also a male XLR connector labeled THRU. This
allows you to connect more than one SRM350 v2 to the output of your mixing console. Simply plug the signal source
output into the first INPUT jack, and patch that speaker’s
THRU jack to the next INPUT jack, and so on, daisy-chaining multiple speakers (see diagram on page 7).
The THRU jack’s signal comes after
the MIC/LINE switch, but before the
LEVEL control. If the MIC/LINE switch
is pushed in on the first SRM350 v2,
the signal at the THRU jack is boosted
by 40 dB to a line level. Therefore,
leave the MIC/LINE switch out on the following SRM350 v2s
in the chain.
As with any powered components,
protect them from moisture. If you are
setting them up outdoors, make sure
they are under cover if you expect rain.
The SRM350 v2 generates a magnetic
field. Do not place it closer than two
feet (0.6 meters) from any TV set or
computer monitor. Check the screen
for any change in color or distortion.
Do not place any magnetic audio or video tapes or
computer discs near the SRM350 v2.
Room Acoustics
SLEEVE
SLEEVE
TIP
The SRM350 v2 active speakers are designed to sound as
neutral as possible; that is, to reproduce the input signal as
accurately as possible, monitoring the sound rather than
changing it.
Room acoustics play a crucial role in the overall
performance of a sound system. However, the wide high-frequency dispersion of the SRM350 v2 helps to minimize the
problems that typically arise.

Here are some useful placement tips:
• Avoid placing loudspeakers in the corners of a room.
This increases the low-frequency output and can cause
the sound to be muddy and indistinct.
• Avoid placing loudspeakers against a wall. This, too,
increases the low-frequency output, though not as
much as corner placement. However, if you do need to
reinforce the low frequencies, this is a good way to do it.
• Avoid placing the active speakers directly on a hollow stage floor. A hollow stage can resonate at certain
frequencies, causing peaks and dips in the frequency
response of the room. It’s better to place the active
speakers on a sturdy table or tripod stands.
• Position the active speakers so the high-frequency
drivers are 2 to 4 feet above ear level for the audience
(make allowances for a standing/dancing in the aisles
audience). High frequencies are highly directional and
tend to be absorbed much easier than lower frequencies. By providing direct line-of-sight from the active
speakers to the audience, you increase the overall
brightness and intelligibility of the sound system.
• Highly reverberant rooms, like many gymnasiums and
auditoriums, are a nightmare for sound system intelligibility. Multiple reflections off the hard walls, ceiling,
and floor play havoc with the sound. Depending on the
situation, you may be able to take some steps to minimize the reflections, such as putting carpeting on the
floors, closing draperies to cover large glass windows,
or hanging tapestries or other materials on the walls to
absorb some of the sound.
However, in most cases, these remedies are not possible
or practical. So what do you do? Making the sound
system louder generally doesn’t work because the
reflections become louder, too. The best approach is to
provide as much direct sound coverage to the audience
as possible. The farther away you are from the speaker,
the more prominent will be the reflected sound.
Use more speakers strategically placed so they are
closer to the back of the audience. If the distance between the front and back speakers is more than about
100 feet, you should use a delay processor to time-align
the sound. (Since sound travels about 1 foot per millisecond, it takes about 1/10 of a second to travel 100
feet).
RIGGING
The SRM350 v2 cabinets are fitted with four M5 insert
points on the top and bottom for installing an optional
hanging bracket that allows the speaker to be flown.
SRM350 Bracket Kit: Part No. 0016404
WARNING: Never attempt to suspend
the SRM350 v2 active speakers by their
handles. If you want to suspend them,
use the hanging brackets only.

If you are hanging them in an inaccessable place, such as over a lion’s cage,
make sure that you first complete the
sound check and set the SRM350 v2
LEVEL correctly.

THERMAL
CONSIDERATIONS
AC POWER
CONSIDERATIONS
The amplifiers inside the SRM350 v2 are
convection cooled by a large heatsink.
For efficient cooling, it is important to
allow at least six inches of free space
behind the SRM350 v2.
If the ambient temperature in the room is high, though
highly unlikely, it could cause the amplifiers to overheat.
In this case, you should try aiming a fan at the heatsink to
increase the air flow through the fins.
During a performance, don’t have it cranked so high that
the rear panel LIMIT LED is blinking frequently or lighting
continuously. You should turn down the LEVEL control a
notch or two to avoid overheating the amplifiers or your
neighbors.
If the amplifiers begin to overheat, the Active Protection
Management System gently reduces the input signal level
until the amplifiers have cooled down to a safe operating
temperature.
Be sure the SRM350 v2 is plugged into an outlet that is
able to supply the correct voltage specified for your model.
If the voltage should drop below 97% of the specified line
voltage, the built-in amplifiers will no longer be able to
supply rated power. (They will continue to operate down
to 75% of the rated line voltage, but won’t reach full power,
resulting in lower headroom.)
Under maximum SPL conditions, where musical peaks
are clipping, the SRM350 v2 120V model draws 2.5 amps on
average (1.3 amps for the 230V model). Under normal conditions, the current draw is below 1 amp.
We recommend that a stiff (robust) supply of AC power
be used because the amplifiers place high current demands
on the AC line. The more power that is available on the line,
the louder the speakers will play and the more peak output
power will be available for cleaner, punchier bass. A suspected problem of “poor bass performance” is often caused
by a weak AC supply to the amplifiers.
AC Power Distribution
A 240VAC center-tapped service entrance transformer
serves the majority of AC outlets encountered in homes and
clubs (in the U.S.). This provides two phases of AC power
on either side of the center tap, at 120V each.
If lighting is used in a show, it is preferable to power
the lights from one leg of the service, and power the audio
equipment from the other leg. This will help minimize
noise from the lights coupling into the audio (particularly if
SCRs, or light-dimmer switches, are used).
Wherever possible, connect all of your equipment to the
same electrical circuit. This will help reduce the possibility
of a ground loop problem causing an annoying hum in your
speakers.
Low power components such as tape decks, mixers, effects processors and CD players should be connected to
the same outlet as the SRM350 v2s. Use fused power strips
as shown in the diagram below. Make sure that the total
current draw of your components does not exceed the capability of the outlets and power strips.

When setting up for a show, often
you are plugging into an AC power
distribution system you know nothing
about. You may even be faced with 2wire outlets that are missing the third
safety ground pin. It’s a good idea to
have a three-wire AC outlet tester in your toolbox so you
can check the outlets yourself to make sure they are wired
correctly. These testers will tell you if the polarity of the
hot and neutral wires is reversed and if the safety ground is
disconnected.
Don’t use an outlet if it is wired improperly! This is to protect yourself as
well as your equipment.
For the US 120 V model:
A maximum of five SRM350 v2s can be connected per
15A service.
This allows each SRM350 v2 to be safely operated at
its maximum level.
When turning your system on, turn on the SRM350 v2s
last. This will stop any turn-on thumps and bangs from your
source equipment being amplified.
When turning off your system, turn off the SRM350 v2s
first. This will prevent any turn-off thumps and bangs from
your source equipment being amplified.
Never remove the ground pin on the
power cord of the SRM350 v2 or any
other component. This is very dangerous.

SERVICE INFORMATION
If you think your loudspeaker has a problem, please
check out the following troubleshooting tips and do your
best to confirm the problem. Visit the Support section of
our website (www.mackie.com/support) where you will find
lots of useful information such as FAQs, documentation,
and user forums. You may find the answer to the problem
without having to send your loudspeaker away.
If you do find the problem, make sure
that you turn down the LEVEL controls
and turn off the SRM350 v2 before correcting it or changing any connections.
Troubleshooting
No power!
• Our favorite question: Is it plugged in? Make sure the
AC outlet is live (check with a tester or lamp).
• Our next favorite question: Is the POWER switch on? If
not, try turning it on.
• Is the blue light on the front panel illuminated? If not,
make sure the AC outlet is live. If so, refer to “No sound”
below.
• The AC line fuse inside the chassis is blown. This is not
a user-serviceable part. Refer to “Repair” on page 16 to
find out how to proceed.
No sound!
• Is the input LEVEL control turned all the way down?
Follow the procedures in the “Quick Start” section
on page 6 to verify that all the volume controls in the
system are properly adjusted.
• Is the signal source working (and making union scale)?
Make sure the connecting cables are in good repair
and securely connected at both ends. Make sure the
output volume (gain) control on the mixing console or
preamp is turned up sufficiently to drive the inputs of
the speaker. You should be able to see the SIGNAL LED
blink on the rear panel.
• Make sure the preamp or mixer does not have a Mute
on, or a Tape or Processor loop engaged. If you find
something like this, make sure the volume/gain is
turned down before disengaging the offending switch.
14
One side is way louder than the other!
• Are the LEVEL controls set the same on both active
speakers?
• Check the PAN control or balance on the signal source.
It may be turned too far to one side. If you’re using a
stereo signal source, it may be delivering an out-of-balance stereo signal.
• Try swapping sides: Turn off the active speakers, swap
the input cables coming from the mixing console, turn
the active speakers back on. If the same side is still
louder, the problem may be with your active speakers or
cables between the mixer and the active speaker. If the
other side is louder now, the problem is with the mixer
or the signal source.
Poor bass performance
• Check the polarity of the connections between the
mixer/preamp and the active speakers. You may have
your positive and negative connections reversed at one
end of one cable, causing one SRM350 v2 to be out-ofphase.
Bad sound!
• Is it loud and distorted? Follow the procedures described in the “Quick Start” section to verify that the
levels are set properly.
• Is the input connector plugged completely into the
jack? Be sure all connections are secure. It’s a good
idea to periodically clean all electrical connections with
a non-lubricating electrical contact cleaner.
Noise
• Make sure all connections to the active speakers are
good.
• Make sure none of the signal cables are routed near
AC cables, power transformers, or other EMI-inducing
devices.
• Is there a light dimmer or other SCR-based device on
the same AC circuit as the SRM350 v2? Use an AC line
filter or plug the SRM350 v2 into a different AC circuit.
• Disconnect any cables which come in from outside,
such as cable TV, satellite TV or roof top antennas. They
must be disconnected from every part of your system,
such as the TV, VCR and preamp. If the hum goes away,
you can add a “ground loop isolator” in your cable line.
This is an inexpensive device available from video or TV
dealers, or you can make your own from two TV baluns
(standard TV 75/300 ohm adaptors):
Hum
• Turn the LEVEL control all the way down. If the noise
disappears, it’s coming from the signal source. If not,
try disconnecting the cable connected to the INPUT
jack. If the noise disappears, it could be a “ground loop,”
rather than a problem with the SRM350 v2. Try some of
the following troubleshooting ideas:
• Use balanced connections throughout your system for
the best noise rejection.
• Whenever possible, plug all the audio equipment’s
linecords into outlets which share a common ground
(see the diagram on page 13). The distance between
the outlets and the common ground should be as short
as possible.
Never remove the ground pin on
the power cord of the SRM350 v2 or
any other component. This is very
dangerous.
Balun
join (+insulate)
Balun
The baluns are threaded at one end (75 ohm) to fit TV
coax cable and have two wires at the other end (300
ohm). They will not affect the video quality.
• If the hum persists, try removing components one at
a time from the back of the mixer or preamplifier, and
check for hum each time (turn off your equipment
before you undo any connections). It is fairly common
to find more than one problem.
• If your preamp or mixer are the only things connected
to the SRM350 v2s and the hum is still there, try different connection cables, or move the preamp/mixer to
another location.
• The hum may appear when using an unbalanced
source (consumer preamp, CD player, VCR, etc.). This
is caused by the unbalanced-to-balanced interface
between the devices (and exacerbated by the fact
that most consumer audio equipment have a two-wire
linecord, without the third-pin safety ground).
Use an interconnect cable wired as shown below. The
important point is that the shield and the wire from the
XLR pin 3 are joined at the RCA (source) end.

Avoid exposing the active speakers to
moisture. If they are set up outdoors,
be sure they are under cover if you
expect rain or you live in Washington.
• Avoid exposure to extreme cold (below freezing temperatures). If you must operate the active speakers in
a cold environment, warm up the voice coils slowly by
sending a low-level signal through them for about 15
minutes prior to high-power operation.
• Use a slighty damp cloth with a mild soap solution to
clean the cabinets. Only do this when the power is
turned off. Avoid getting moisture into any of the openings of the cabinet, particularly where the drivers are
located.
