INTRODUCTION  
Thank you for choosing Mackie’s active sound reinforce- mammoth aluminum heatsink that eliminates the need  
ment loudspeaker systems.  
for fans. A tremendous benefit of having the ampli-  
fiers located within the loudspeaker cabinet is that the  
SR1521z functions as a system, optimizing acoustic,  
electronic, and mechanical designs to achieve the high-  
est level of performance and value.  
The SR1521z is a high-efficiency, high output, horn-  
loaded, 2-way, wide-dispersion, active sound reinforce-  
ment system. The SR1521z benefits from the integration  
of 500 watts of amplifier power, complete active control  
electronics, and precision transducer components.  
These elements together form a speaker system with  
unprecedented output, resolution, and clarity.  
The rear mounted amplifier assembly features  
separate signal and AC power panels separated by the  
heatsink. The signal input panel contains:  
• an input XLR and loop-through XLR  
• a volume level control  
The 1.75-inch neodymium high-frequency compres-  
sion driver features a low-distortion optimized symmet-  
ric phase plug.  
• Power ON indicator  
• Signal Present indicator  
• Limit indicator  
• Thermal Protection indicator  
The low frequencies are produced by a high-output  
15-inch woofer featuring a 2.5-inch high-temperature  
voice coil.  
The cabinet is constructed using both 18 mm Baltic  
birch plywood and pressure injected structural resin.  
A carrying handle is integrated into each side for easy  
loading and transport.  
Connecting and setting up the SR1521z is a breeze. It  
accepts a line-level signal via a female XLR input jack.  
A male XLR Thru jack is provided for daisy-chaining the  
signal to additional SR1521z cabinets.  
Two built-in power amplifiers provide 100 watts rms  
for the high-frequency driver and 300 watts rms for the  
low-frequency driver. The amplifier modules sit on a

REAR PANEL DESCRIPTION  
1. MAIN INPUT  
This is a female XLR-type connector that  
accepts a balanced line-level signal from a  
mixing console or other signal source.

This is a male XLR-type connector that  
produces exactly the same signal that is  
connected to the MAIN INPUT jack. Use it to  
daisy-chain several SR1521z's together off the  
same signal source.

7. THERMAL Indicator  
There is also a thermal protection circuit that mon-  
itors the internal temperature of the amplifiers and  
heatsink. If the temperature should exceed a safe oper-  
ating level, this indicator lights and the signal is muted to  
allow the amplifiers to cool. When the temperature cools  
to a safe level once again, the thermal protection circuit  
deactivates and normal operation continues.  
3. Level Control  
This controls the overall signal level at the input to  
the built-in power amplifiers. It ranges from –15 dB to  
+5 dB of gain. The center detent is 0 dB (unity gain).  
4. Power ON Indicator  
Note: Activation of the thermal protection circuit is  
an indication that you should take steps to avoid con-  
tinued thermal problems. See “Thermal Considerations”  
on page 6.  
When the POWER switch is turned on, and the  
linecord is connected to an active AC power supply, this  
indicator lights green to let you know that you’re ready  
to rock and roll. The cool blue LED on the front of the  
cabinet works in the same way.  
8. POWER Switch  
5. SIGNAL Present Indicator  
Use this switch to turn the SR1521z on and off. Make  
sure the level control is turned down before you turn it  
on.  
This LED illuminates whenever there is a signal pres-  
ent at the MAIN 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 Present  
indicator turns off.  
9. AC Receptacle  
This is where you connect the AC linecord to provide  
AC power to the SR1521z’s built-in power amplifiers.  
Plug the linecord into an AC socket properly configured  
for your particular model.  
6. LIMIT Indicator  
The SR1521z has a built-in limiter that prevents the  
amplifier outputs from clipping or overdriving  
the transducers. The LIMIT indicator lights  
when the limiter is activated. It's okay for the  
LIMIT indicator to blink occasionally, but if it  
blinks frequently or lights continuously, turn  
down the level control until the LIMIT indica-  
tor only blinks occasionally.

DAISY-CHAINING MULTIPLE SR1521z'S  
The LOOP OUT jack is wired straight from the MAIN  
INPUT connector — there is no electronic circuitry  
between — so the signal coming out of the LOOP OUT  
jack is exactly the same as the signal going in.  
CONNECTIONS  
The SR1521z has one female XLR input that accepts  
a balanced line-level signal. When connecting a balanced  
signal, be sure it’s wired per AES (Audio Engineering  
Society) standards:  
PLACEMENT  
XLR  
The SR1521z speaker is designed to sit on the floor or  
stage. It can be pole-mounted via the built-in socket on  
the bottom of the cabinet. Be sure the pole is capable of  
supporting the weight of the SR1521z.

Pin 3  
Shield (Ground) Pin 1  
WARNING: The cabinet has no rig-  
ging points and is not suitable for  
rigging. NEVER attempt to suspend  
the SR1521z by its handles.  
You can create a horizontal array by placing the cabi-  
nets side-by-side. However, you should have a good un-  
derstanding of the relationship between the splay angle  
(the angle between the facing sides of the cabinets),  
the on-axis power, and frequency cancellation effects  
between cabinets.  
Balanced XLR Connectors  
When two cabinets are placed side-by-side, the actual  
splay angle is 20º (determined by a 10º angle on each  
cabinet side). As the splay angle increases toward the  
angle of horizontal coverage (90º for the SR1521z), the  
on-axis power decreases, but the frequency response be-  
comes smoother as the comb-filtering effects (caused by  
the interaction in the area of double-coverage) decrease.  
There is also a male XLR connector labeled LOOP  
OUT. This is also wired according to the above AES  
standard.  
The LOOP OUT connector allows you to connect  
more than one SR1521z to your system. Simply plug the  
signal source (i.e., mixer output) into the first MAIN  
INPUT jack, and patch that speaker’s LOOP OUT jack  
to the next MAIN INPUT jack, and so on, daisy-chaining  
multiple speakers.  
As with any powered components,  
protect them from moisture. If you  
are setting them up outdoors, make  
sure they are under cover if you  
5
expect rain.  
 
Room Acoustics  
THERMAL CONSIDERATIONS  
The SR1521z loudspeakers are designed to sound as  
neutral as possible; that is, to reproduce the input signal  
as accurately as possible.  
The SR1521z has two powerful built-in amplifiers  
capable of producing a combined 500 watts of power.  
As amplifiers produce heat, it is important to dissipate  
the heat as quickly as possible. This results in increased  
reliability and longevity for the amplifier.  
Room acoustics play a crucial role in the overall per-  
formance of a sound system. Here are some additional  
placement tips to help overcome some typical room  
problems that might arise:  
The amplifier module is mounted on a large heatsink,  
which is cooled by convection where cool air is drawn  
through it’s fins, carrying the heat away. In order for this  
convection cooling to work efficiently, it is important  
to provide adequate airspace behind the loudspeaker.  
When you position the SR1521z, we recommend leaving  
at least six inches of air space behind it.  
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.  
In the unlikely event of the amplifier overheating, a  
built-in thermal switch will activate, which mutes the  
signal and lights the THERMAL LED. When the amplifi-  
er has cooled down to a safe operating temperature, the  
thermal switch resets itself, and the SR1521z resumes  
normal operation.  
Avoid placing the speakers directly on a hollow  
stage floor. A hollow stage can resonate at certain  
frequencies, causing peaks and dips in the fre-  
quency response of the room. It’s better to place the  
loudspeakers on a sturdy table or stand designed to  
handle the weight of the SR1521z.  
If the thermal switch activates frequently, try turning  
down the level control a notch or two on the mixing con-  
sole (or the back of the SR1521z) to avoid overheating  
the amplifier.  
Position the loudspeakers 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  
loudspeakers to the audience, you increase the over-  
all brightness and intelligibility of the sound system.  
If the temperature in the room is too high, it could  
cause the amplifier to overheat. In this case, you should  
try aiming a fan at the rear panel to move more air  
through the heatsink fins.  
AC POWER  
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. Depend-  
ing 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.  
Be sure the SR1521z 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 spec-  
ified line voltage, the built-in amplifiers will no longer  
be able to supply rated power. (They will continue to  
operate down to 80% of the rated line voltage, but won’t  
reach full power, resulting in lower headroom.)  
Be sure the electrical service can supply enough am-  
perage for all the components connected to it.  
However, in most cases, these remedies are not possi-  
ble 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.  
We recommend that a stiff (robust) supply of AC  
power be used because the amplifiers place high cur-  
rent 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.  
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.)  
Never remove the ground pin on  
the power cord of the SR1521z or  
any other component. This is very  
dangerous.

SERVICE INFORMATION  
Warranty Service  
Poor bass performance  
Check the polarity of the connections between the  
mixer and the loudspeakers. You may have your  
positive and negative connections reversed at one  
end of one cable, causing one loudspeaker to be  
out-of-phase.  
Details concerning warranty service are spelled out  
on page 11 of this manual.  
If you think your loudspeaker has a problem, please do  
everything you can to confirm it before calling for service,  
including reading through the following Troubleshooting  
section. Doing so might save you from being deprived of  
your Mackie loudspeaker.  
Poor sound  
Is it loud and distorted? Make sure that you’re not  
overdriving a stage in the signal chain. Verify that  
all level controls are set properly.  
Of all Mackie products returned for service (which is  
hardly any at all), many are coded “CND” — Could Not  
Duplicate— which usually means the problem lay some-  
where else in the system. The following troubleshooting  
tips may sound obvious, but here are some things you  
can check:  
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.  
Troubleshooting  
Noise  
Make sure all connections to the active loudspeak-  
ers are good and sound.  
No power  
Make sure none of the signal cables are routed near  
AC cables, power transformers, or other EMI-induc-  
ing devices.  
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 there a light dimmer or other SCR-based device  
on the same AC circuit as the SR1521z? Use an AC  
line filter or plug the SR1521z into a different AC  
circuit.  
Is the POWER LED on the rear panel glowing  
green? If not, make sure the AC outlet is live. If so,  
refer to “No sound” below.  
The internal AC line fuse may be blown. This is not  
a user serviceable part. If you suspect the AC line  
fuse is blown, please see the "Repair" section next.  
Hum  
Try disconnecting the cable connected to the MAIN  
INPUT jack. If the noise disappears, it could be  
a “ground loop,” rather than a problem with the  
SR1521z. Try some of the following troubleshooting  
ideas:  
No sound  
Is the input level control for the input source  
turned all the way down? Verify that all the volume  
controls in the system are properly adjusted.  
Use balanced connections throughout your  
system for the best noise rejection.  
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 is turned up sufficiently to drive the inputs of  
the speaker.  
Whenever possible, plug all the audio equip-  
ment’s linecords into outlets which share a common  
ground. The distance between the outlets and the  
common ground should be as short as possible.  
Make sure the mixer does not have a Mute on or a  
Processor loop engaged. If you find something like  
this, make sure the volume/gain is turned down  
before disengaging the offending switch.  
Is the THERMAL indicator lit red on the rear panel?  
Make sure there is at least six inches of free space  
behind the SR1521z.

number ready. You must have a Service Request  
Number before you can obtain service at a factory-  
authorized service center.  
CARE AND MAINTENANCE  
Your Mackie loudspeakers will provide many years of  
reliable service if you follow these guidelines:  
Avoid exposing the loudspeakers to  
moisture. If they are set up out-  
doors, be sure they are under cover  
if you expect rain.  
3. Keep this user’s manual and the detachable line-  
cord. We don’t need them to repair the loudspeaker.  
Avoid exposure to extreme cold (below freezing  
temperatures). If you must operate the loud-  
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.  
4. Pack the loudspeaker in its original packaging,  
including protective wrap, endcaps, and box. This  
is VERY IMPORTANT. When you call for the Service  
Request Number, please let Tech Support know if  
you need new packaging. Mackie is not responsible  
for any damage that occurs due to non-factory  
packaging.  
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 driv-  
ers are located.  
5. Include a legible note stating your name, shipping  
address (no P.O. boxes), daytime phone number,  
Service Request Number, and a detailed description  
of the problem, including how we can duplicate it.  
6. Write the Service Request Number in BIG  
PRINT on top of the box. Product shipped with-  
out the Service Request Number will be refused.  
7. Tech Support will tell you where to ship the loud-  
speaker for repair. We suggest insurance for all  
forms of cartage.

not authorize any third party, including any dealer or  
sales representative, to assume any liability on behalf of  
LOUD Technologies or to make any warranty for LOUD  
Technologies Inc.  
2. Pack the product in its original shipping carton. Also  
include a note explaining exactly how to duplicate the  
problem, a copy of the sales receipt with price and date

not allow exclusion or limitation of incidental, special,

E. LOUD Technologies reserves the right to inspect  
any products that may be the subject of any warranty  
claims before repair or replacement is carried out. LOUD

of the original dealer’s invoice or sales receipt. Final  
determination of warranty coverage lies solely with LOUD  
Technologies.
