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.

SR1521Z

ACTIVE SOUND REINFORCEMENT

SPEAKER SYSTEM

2. LOOP OUT

��

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.

Cold (–)

Pin 2

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

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.

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.
