radioélectriques dépassant las limites applicables aux appareils numériques de
class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage
radioélectrique édicté par les ministere des communications du Canada.
19. Exposure to extremely high noise levels may cause permanent hearing
loss. Individuals vary considerably in susceptibility to noise-induced
hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limits
could result in some hearing loss. To ensure against potentially danger-
ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres-
sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here.

INTRODUCTION
Thank you for choosing a Mackie compact active PA
system for your sound reinforcement applications.
The SRM150 is an active PA system that provides a
built-in mixer, high sound pressure levels, and is de-
signed to give you the best performance of any compact
PA system in its class and price range.
Our design goal was to build a compact PA system with:
1. High precision, high output, and accurate playback.
2. Controlled, smooth dispersion of mid and high
frequencies.
3. Ultra-clean, high-headroom mic preamps.
4. High-output Class-D amplification.
5. Onboard Mackie mixer with 3-band EQ.
Through the combined resources of our top-notch me-
chanical and analog engineers, we were able to achieve
our design goals in every aspect. The result is a sound re-
inforcement PA system equally at home in a concert setting,
in the studio, or impromptu concerts on the studio roof.
The Transducer
The SRM150 active loudspeaker features a full-range
5.25-inch neodymium driver.
Power Amplier
Each SRM150 includes a Class-D power amplifier
capable of producing 150 watts peak before clipping.
The amplifier includes the following features:
• The amplifier produces up to 100 watts rms continuous
before clipping (150 watts peak).
• A built-in limiter acts when the input signal is large
enough to cause clipping, distortion, and excessive
voice coil heat. The limiter will automatically decrease
the signal going to the amplifier to a safe level.
Warning: Although the amplifier has
a limiter protection circuit, you must
still make sure you don’t overdrive
the amplifier. If you hear any distor-
tion, turn down the input (MIC/LINE)
gain control, or turn down the MAIN
LEVEL control.
The Cabinet
The SRM150 cabinet was designed with the same
material as our SRM350 and SRM450 loudspeakers, the
strongest molded composite cabinet on the planet. It
has an insert in the bottom for mic stand mounting (us-
ing the mic stand adapter included with your SRM150),
and a threaded insert in the top for mounting a micro-
phone boom (using the included boom extender).
Its light weight and durable finish make it ideal for
portable sound system use. In addition, the unique de-
sign 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 amplifiers are designed specifically for the speaker
load impedance. There is no guesswork as to what load
the amplifier has to drive, so it can provide maximum
acoustic output from the speaker, yet minimize the
danger of speaker damage due to overdriving a lesser
amplifier.
• The connecting wires between the amplifier output and
the driver is 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 driver with no
speaker cable losses.
• 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.
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.

QUICK START
1. Start with the following settings on the front of the
SRM150:
• MAIN LEVEL [6] control down.
• PHANTOM POWER [5] switch out (unless you are
using condenser microphones).
• INSTRUMENT [4] switch out (unless you have an
electric guitar connected to channel 1).
• Channels 1-3 gain [3] controls down.
• EQ [7] controls centered.
And on the rear panel:
• Turn the POWER [8] switch off (down).
• MIC/LINE [12] switch out.
WARNING: Turn the MAIN LEVEL
[6]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 MIC/LINE [1] combo
connector on the front of the SRM150. It accepts
balanced line-level signals from mixers, preamplifi-
ers, CD players, tape decks, etc., and accepts direct
connections from microphones. Channel 3 has ste-
reo RCA jacks [2] specifically for a stereo line-level
input from a tape deck or CD player.
3. Connect the supplied AC power cord to the AC
power receptacle [10] on the back of the SRM150.
Plug the other end into an AC outlet properly con-
figured with the correct voltage for your particular
model. (The SRM150 has a universal power supply
that accepts an AC mains voltage ranging from 100V
to 240 V.)
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 SRM150 POWER [8] switch.
6. Start the signal source, whether it be speaking into
a microphone, playing a guitar, or starting a CD
player. Adjust any volume controls on the signal
source for normal operation.
7. Turn up the MAIN LEVEL [6] control about halfway
(12 o’clock).
8. Slowly turn up the gain [3] controls for the input
channels until the desired volume is reached.
9. If it gets really loud, really fast, try turning down
the MAIN LEVEL control (or the input source
volume control, if it has one).
If it doesn’t get very loud, even with the input chan-
nel gain control all the way up, try turning up the
MAIN LEVEL control (or the input source volume
control, if it has one).
10. If there is no sound, always turn down the SRM150
MAIN LEVEL control before investigating. There
may be a mixer or preamplifier mute or tape switch
engaged, or a mic switch off.

FRONT PANEL DESCRIPTION
Plugging a guitar straight into a
typical line-level input can result in
the loss of gain, especially at high
frequencies, resulting in a dull sound.
Normally, you must use a direct box
between a guitar and a mixer’s or preamplifier’s input,
which serves to convert the impedance of the guitar
from high to low. The Instrument input on channel 1
makes the need for a direct box unnecessary. It’s like it
has its own built-in direct box!
However: The Instrument input is unbalanced, so if you
are running a long cord between the instrument and the
SRM150 (say over 20 feet), it is best to use a direct box
with a balanced output to avoid picking up noise over
the length of the cord.
5. 48V PHANTOM POWER Switch and
Indicator
Most professional condenser microphones require phan-
tom power, which is a low-current DC voltage delivered
to the microphone on pins 2 and 3 of the XLR micro-
phone connector. Push in the 48V button if your micro-
phone requires phantom power. An LED lights next to
the button to indicate that phantom power is active.
Most of the connections and controls on the SRM150
are located on the front panel for easy access.
1. MIC/LINE Inputs
Channels 1 and 2 have Neutrik® combo connectors,
which accept balanced microphone inputs from an XLR
connector, or balanced and unbalanced line-level inputs
from a 1/4" TRS or TS connector.
The XLR inputs are wired as follows:
Pin 1 = Shield or ground
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
The 1/4" inputs are wired as follows and will accept
both balanced and unbalanced inputs:
Sleeve = Shield or ground
Tip = Positive (+ or hot)
Ring = Negative (– or cold)
2. Stereo Input
Channel 3 has a pair of RCA connectors, which accept
a stereo line-level input from a CD player or MP3 player
(or any other line-level device).
3. Channel Gain Controls
These are used to adjust the signal level for each
individual channel. Since the SRM150 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.
Follow the Quick Start guide on page 4 for setting
the gain controls. For most applications, it will be in
the 12 o’clock position. If you have a particularly high
line- level signal connected to the SRM150, 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 con-
nected, you may need to turn the gain control up to the
3 o’clock position.
4. INSTRUMENT Switch (CH 1)
Push in this button to change the 1/4" line input
on channel 1 to an instrument input. When the but-
ton is out, the 1/4" input accepts normal line-level
signals from low-impedance sources. When the button
is pushed in, the 1/4" input accepts high-impedance
signals from instruments with electric pickups, which
you would normally run through a DI box.

This is a global phantom power switch and applies 48V
to the XLR input connectors on channels 1 and 2.
Dynamic microphones, like Shure’s SM57 and SM58, do
not require phantom power. However, phantom power
will not harm most dynamic microphones should you
accidentally plug one in while the phantom power is
turned on. Be careful with older ribbon microphones.
Check the manual for your microphone to find out for
sure whether or not phantom power can damage it.
6. MAIN LEVEL
This is used to adjust the signal level from the
SRM150 mixer, going into the built-in power amplifier.
Follow the Quick Start guide on page 4 for setting the
MAIN LEVEL control.
7. HIGH, MID, and LOW EQ
Use the EQ controls to make overall adjustments to
the sound of the SRM150.
The HIGH EQ provides a boost or cut of up to 15
dB for the very high frequencies, above 12 kHz. These
frequencies include the sizzle of cymbals, the edge of
a guitar, or the upper harmonics of vocals. In general,
boosting the HIGH EQ will brighten the sound of the
loudspeaker.
The MID EQ provides a boost or cut of up to 15 dB for
the mid-range frequencies around 2.5 kHz. Most vocals
are located in the mid-range frequencies, so this can be
used to bring the vocals up or down in the mix.
The LOW EQ provides a boost or cut of up 15 dB for
the very lowest frequencies, below 100 Hz. These fre-
quencies are represented by the punch in bass drums,
bass guitar, and some really serious male singers.

8. POWER Switch
Switch up to turn the SRM150 on, and switch down
to turn it off. Make sure the MAIN LEVEL [6] control is
down before you turn it on.
When the POWER switch is turned on, and the line-
cord is connected to an active AC Mains supply, the cool
blue LED on the front of the speaker glows to let you
know that you’re ready to rock and roll.
9. FUSE
This is a resettable circuit breaker that monitors the
amount of current being drawn by the SRM150. Under
normal operating conditions, this should never pop. An
unusual condition may cause the breaker to pop, such
as a mains voltage surge occurring at the same time as a
peak amplifier output.
To reset the breaker:
• Turn the POWER [8] switch off and push the FUSE
switch to its UP position.
• Turn the POWER switch back on and the SRM150
should resume normal operation. If the circuit
breaker pops again, there may be something wrong
inside the SRM150. Refer to “Repair” on page 15.
10. AC Power Receptacle
This is a standard 3-prong IEC connector. Connect
the detachable linecord (included with your SRM150)
to the power receptacle, and plug the other end of the
linecord into an AC outlet. The SRM150 has a universal
power supply that can accept any AC voltage ranging
from 100VAC to 240 VAC. No need for voltage select
switches. It will work virtually anywhere in the world.
Note: If you happen to lose the AC linecord, replace-
ments are readily available at any office or computer
supply store. Always use a three-pin plug with a ground
pin.
11. THRU Connector
This is a male XLR connector that produces the main
signal just prior to the EQ [7] controls and the MAIN
LEVEL [6] control. The signal at the THRU connector
includes the input signals connected to channels 1-3
[1/2] and the MAIN IN [13] signal.
Use this connector to patch the signal from the
SRM150 to another SRM150 or other active loudspeaker
(like an SRM350 or SRM450), or to a mixer.
12. MIC/LINE Switch
The MIC/LINE switch affects the output level of the
THRU connector. Leave the switch out (LINE) when
connecting the THRU connector to another SRM150
or to a line-level input on a mixer. Push the switch in
(MIC) when connecting the THRU connector to a mi-
crophone input on a mixer or a stage snake.
13. MAIN IN
This is a Neutrik combo connector that accepts a
balanced line-level signal from an XLR connector or a
1/4" TRS connector. The signal is mixed with the signals
from channels 1-3 on the main mix bus, just prior to
the THRU [11] output, EQ [7] controls and the MAIN
LEVEL [6] control.

11
PLACEMENT
The SRM150 compact active PA systems are designed
to sit on the floor, a tabletop, or to fit on a standard
microphone stand.
You can place the SRM150 on the floor and angle
it back to use it as a floor monitor. The unique shape
of the cabinet provides a perfect angle for aiming up
toward performers from the front of the stage.
You can also use the Mic Stand Adapter (included),
which allows you to mount the SRM150 onto a standard
microphone stand.

In addition, there is a threaded insert on top of the
cabinet for mounting the boom extender (included).
This allows you to attach a microphone boom on top of
the SRM150 for your microphone.

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.
THERMAL CONSIDERATIONS
The amplifier inside the SRM150
is convection cooled by a large
heatsink. For efficient cooling, it is
important to allow at least six inches
of free space behind the SRM150.
If the ambient temperature in the room is high, it
could cause the amplifier to overheat. In this case, you
should try aiming a fan at the heatsink to increase the
air flow through the fins.
In the unlikely event that the amplifier does over-
heat, a built-in thermal switch will activate, placing
the SRM150 amplifier into standby. When the amplifier
has cooled down to a safe operating temperature, the
thermal switch will reset and the SRM150 will resume
normal operation.
Here are some other 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 loudspeaker directly on a hol-
low 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
loudspeaker on a sturdy table or microphone stand.

12
AC POWER CONSIDERATIONS
Be sure the SRM150 is plugged into an outlet that is
able to supply enough current for the amplifier.
Under maximum SPL conditions, where musical peaks
are just hitting the limiter, the SRM150 model draws 2
amps on average. Under normal conditions, the current
draw is below 1 amp.
We recommend that a stiff (robust) supply of AC
power be used because the amplifier places high cur-
rent demands on the AC line. The more power that is
available on the line, the louder the speaker 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 amplifier.
If lighting is used in a show, it is preferable to power
the lights from a separate AC circuit than the one
powering the audio equipment. This will help minimize
noise from the lights coupling into the audio (particu-
larly if SCRs, or light-dimmer switches, are used).
Wherever possible, connect all of your audio equip-
ment to the same electrical circuit. This will help
reduce the possibility of a ground loop problem causing
an annoying hum in your speakers.
A maximum of five SRM150s can be connected per
15A service (120 VAC). This allows each SRM150 to be
safely operated at its maximum level.
When turning your system on, turn on the SRM150s
last. This will stop any turn-on thumps and bangs from
your source equipment being amplified.
When turning off your system, turn off the SRM150s
first. This will prevent any turn-off thumps and bangs
from your source equipment being amplified.
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 2-
wire 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 im-
properly! This is to protect yourself
as well as your equipment.
Never remove the ground pin on the
power cord of the SRM150 or any other
component. This is very dangerous.
CARE AND MAINTENANCE
Your Mackie active loudspeaker will provide many
years of reliable service if you follow these guidelines:
Avoid exposing the loudspeaker to
moisture. If it is set up outdoors, be
sure it is under cover if you expect rain
or you live in Washington.
• Avoid exposure to extreme cold (below freezing
temperatures). If you must operate the loudspeaker
in a cold environment, warm up the voice coil slowly
by sending a low-level signal through it for about 15
minutes prior to high-power operation.
• Use a slighty damp cloth with a mild soap solution
to clean the cabinet. Only do this when the power
is turned off. Avoid getting moisture into any of the
openings of the cabinet, particularly where the driver is
located.

SERVICE INFORMATION
Bad sound!
• Is it loud and distorted? Follow the procedures de-
scribed 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 SRM150? Use an AC line
filter or plug the SRM150 into a different AC circuit.
Hum
• Turn the MAIN LEVEL control all the way down. If the
noise disappears, it’s coming from the signal source. If
not, try disconnecting the cables connected to the input
jacks one at a time. If the noise disappears, it could be a
“ground loop,” rather than a problem with the SRM150.
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 line-
cords into outlets which share a common ground. 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 SRM150 or any other
component. This is very dangerous.

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 resettable circuit breaker has popped. Refer to
“FUSE” [9] on page 10 for information on the circuit
breaker.
No sound!
• Is the input gain control [3] or the MAIN LEVEL [6]
control turned all the way down? Follow the procedures
in the “Quick Start” section on page 4 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 whatever is connected to the
SRM150 is turned up sufficiently to drive the inputs of
the speaker.
