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
dangerous exposure to high sound pressure
levels, it is recommended that all persons
exposed to equipment capable of producing
high sound pressure 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 a permanent hearing loss if exposure is in excess of the
limits set forth ­here.

14.Rigging Precautions: When mounting or suspending Mackie loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading, and any
other contributing factors affecting the loudspeaker installation.
The user must determine the proper safety factor for specific applications and the required load rating of the connection to structure. Comply with all applicable federal, state, and local regulations.
Mackie strongly recommends the following rigging system practices:
Documentation: Thoroughly document the mounting/rigging design with
detailed drawings and parts lists.
Analysis: Have a licensed structural engineer or other qualified professional review and approve the mounting/rigging design before its
implementation.
Installation: Use personnel experienced and qualified for mounting/rigging
loudspeakers in accordance with and in compliance with all federal,
state and local regulations.
DANGER: Loudspeakers should be mounted or suspended only by persons
with knowledge of the proper hardware and rigging techniques. When
stacking or pole-mounting loudspeakers, be sure that they are stabilized
and secured from falling over or being accidentally pushed over. Failure to
follow these precautions may result in damage to the equipment, personal
injury, or death.

INTRODUCTION
Thank you for choosing Mackie sound reinforcement loudspeakers.
The C300z is a portable two-way loudspeaker
system, specifically designed to complement our
PPM Series line of professional powered mixers. They are capable of extremely high sound
pressure levels, and designed to give you the best
performance of any loudspeaker in its class and
price range.
The Transducers
The C300z features a 12-inch high-power
low-frequency woofer and a 1.75-inch titanium
diaphragm high-output compression driver. The
woofer incorporates technology used in largeformat touring systems and, with a massive,
precision 3-inch voice coil, is virtually indestructible.
The high-frequency compression driver is
mounted on a multi-cell aperture loaded on a
constant directivity horn, providing an ultrawide, controlled dispersion pattern 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.
Each driver has been specifically designed by
our engineers for optimum performance in a lightweight high-strength cabinet.
The Crossover
This unique Low Impedance Compensated
Crossover (LICC) design places inductors in series with the woofer whose values are markedly
lower than conventional designs. This reduces
the amount of energy that is typically wasted as
heat and increases the amount of energy that is
transformed into real acoustic power. It also incorporates dynamic protection for the compression
driver from non-linear signals.
The Cabinet
The C300z cabinet was designed to be the
strongest molded composite cabinet on the planet.
This material is as strong as a rhinoceros horn,
and rigid enough to prevent unwanted vibrations
and standing waves in the cabinet. It has built-in
fly points for hanging, and a socket in the bottom
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 also
makes it easy to use as a floor wedge for stage
monitor applications.
The C300z offers a portable, lightweight
solution for a variety of high-powered sound reinforcement applications.

The C300z can
be used with a
Mackie SWA1501 (or
SWA1801) subwoofer
to create an incredibly
powerful system.
The active crossover
inside the subwoofer
splits the full-range
stereo input signal into
two ranges. The SWA1501
sums the left and right
low-frequency range and
plays it through its builtin amplifier and 15-inch
woofer. It sends the stereo high-pass range to the
C300zs, via an external
power amplifier.
The C300z can be
pole-mounted on top of
the SWA1501 or 1801 as
shown.

PLACEMENT
The C300z loudspeakers 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, shown at the right (also see "Rigging" on the next page).
You can lay the cabinet down on its side and use
the C300z 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.
Warning: Do not stack speakers in a column. This is to
avoid the danger of toppling
speakers.
As with any loudspeakers, protect them from
moisture. If you are setting them up outdoors,
make sure they are under cover if you expect rain.
Room Acoustics
The C300z loudspeakers are designed to sound
as neutral as possible; that is, to reproduce the input signal as accurately as possible, monitoring the
audio signal 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 C300z helps
to minimize the problems that typically arise.

up to 20 kHz
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 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 loudspeakers on a sturdy table or tripod stands.
• 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 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.)
PROTECTION
A protection circuit is built into the C300z to
protect the high-frequency compression driver
from excessive power. When the power to the HF
driver approaches the maximum, the power delivered to the driver is momentarily reduced.
CAUTION: The protection
circuit is designed to protect
the HF driver under reasonable
and sensible conditions. Should
you choose to ignore the warning signs (i.e., frequent clip
LED indications, excessive distortion), you can
still damage the speakers in the C300z by overdriving them past their recommended amplifier
power-handling ratings, or past the point of amplifier clipping. Such damage is beyond the scope
of the warranty.
Amplifier Power
We give you three power-handling numbers for
the C300z: rms (continuous), music, and peak. So
how much power do you really need to drive the
C300z?
The answer to that question depends on what
type of program material you are running through
the system and how loud it needs to be.
Some audio signals have lots of momentary
peaks whose amplitudes extend far above the
average overall level of the program. Percussion instruments are a good example of this. Other types
of signals, like highly compressed rock music, have
a higher average signal level with fewer peaks.
Speech reinforcement requires less power overall,
but involves large moment-to-moment variations
in level.
Assuming you want to use the full capability
of the loudspeaker, and the program contains at
least some momentary peaks, we recommend that
you use an amplifier that is rated at twice the continuous power rating of the loudspeaker (into 8
ohms). For the C300z, this would be 300 watts x 2
= 600 watts per channel into 8 ohms. This insures
that the amplifier can reproduce peaks that are 6 dB
higher than the continuous (rms) power-handling
rating before clipping occurs.
Preventing Loudspeaker Damage
Speaking of clipping, this is likely the number
one cause of damage to loudspeakers. Clipping occurs when the signal at the output of any device
in the system (not just the amplifier) reaches its
maximum level. The input signal to the device
may continue to increase, but the output simply
stops, and is characterized by a “flat-top” appearance to the waveform when viewed on an
oscilloscope.
Normal Sine Wave Signal ☺
Clipped Sine Wave Signal Clipping interrupts the motion of the transducer, creating distortion and excessive heat in the
driver, which can damage it over time.
Some folks think that if they use a power amplifier whose power rating is below the maximum
power-handling rating of the loudspeaker, then
they can’t possibly damage the loudspeaker. But if
the amplifier is driven into clipping, even a lower
power amplifier can damage the loudspeaker.
The bottom line is that to prevent damage to
the loudspeakers, you must have a properly operating sound system. Proper operation of a sound
system includes being aware of the types of audio
signals being reproduced, controlling the output
levels accordingly, and operating all the devices in
the system so that no clipping occurs within the
signal chain.
RIGGING
The C300z cabinets are fitted with ten rigging
points as shown in the diagram on the previous
page. These are M10 inserts. M10 threaded eyebolts (M10 x 1.5 mm x 20 mm) are available to fit
in these inserts (PA-A1 Eyebolts).
WARNING: Never attempt to
suspend the C300z loudspeakers by their handles. If you
want to suspend them, use the
rigging points only. Consult a
professional rigger or structural
engineer prior to suspending loudspeakers from a
structure not intended for that use. Always know
the working load limit of the structure supporting
the loudspeaker array. Always make sure that the
rigging hardware minimum rating is at least five
times the actual load.
SERVICE INFO
If you think your Mackie product 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 Mackie product away.
Bad sound!
• Is it loud and distorted? Follow the procedures
described in the “Quick Start” section to verify
that the levels are set properly.
• Are all the connections secure? It’s a good
idea to periodically clean all electrical connections with a non-lubricating electrical contact
cleaner.
• Keep practicing.
Troubleshooting
No sound!
• Are the level controls on the mixer or amplifier 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 all the connecting cables are
in good repair and securely connected at both
ends.
One side is way louder than the other!
• Are the level controls set the same for both
channels on the mixer and amplifier?
• Check the PAN control 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: Switch the speaker cables
coming from the amplifier at the amplifier end.
If the other side is louder now, the problem
is with the amplifier, the mixer, or the signal
source.
Poor bass performance
• Check the polarity of the connections between
the amplifier and the loudspeakers. You may
have your positive and negative connections
reversed at one end of one cable.
It hurts when I touch my arm, or my leg, or even
my head!
• You have a broken finger.

CARE AND MAINTENANCE
Your Mackie loudspeakers will provide many
years of reliable service if you follow these simple
guidelines:
• Avoid exposing the loudspeakers to moisture.
If they are set up outdoors, be sure they are
under cover if you expect rain.
• Avoid exposure to extreme cold (below freezing temperatures). If you must operate the
loudspeakers 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 slightly damp cloth with a mild soap
solution to clean the cabinets. Avoid getting
moisture into any of the openings of the cabinet, particularly where the drivers are located.
CONNECTIONS
The C300z has 1/4" TS and Speakon™ style INPUT and THRU connectors. The connectors are
wired in parallel, so use only one of the input connectors (either 1/4" TS or Speakon-style).
Do not use coaxial cable like
a guitar cord to make speaker
connections. They are not
designed to handle the high
currents produced by a power
amplifier and can overheat.
As the distance between the amplifier and
speakers increases, the thickness of the wire
should also increase. Speaker wire has resistance,
and when electricity passes through a resistor,
power is lost. The thicker the wire, the less the resistance it offers, and the more power actually gets
to the speaker.
1/4" TS Phone Plugs and Jacks
“TS” stands for Tip-Sleeve, the two connections available on a mono 1/4" phone jack or plug.
They are used for unbalanced signals and speaker
connections.

THRU
C300z Connector Panel
Normally, you would use only one THRU
connector, but it is possible to use both THRU
connectors. Keep in mind that all the speakers are
connected in parallel through these connectors, so
you want to be sure not to go below the minimum
impedance requirement for your amplifier.
The C300z has a nominal impedance of 8 ohms.
Two C300zs in parallel equals 4 ohms.
Three C300zs in parallel equals 2.7 ohms.
Four C300zs in parallel equals 2 ohms.
Use heavy gauge, stranded wire for connecting a
speaker to the output of a power amplifier.
This connector is compatible with the popular
Neutrik® Speakon® 4-pole plugs. These connectors are designed to handle the higher currents
produced by amplifiers, and have a locking feature to prevent accidental disconnections. Simply
line up the tabs on the plug with the jack on the
C300z, push it in, and rotate it 1/4 turn to the
right to lock it in place.

Please keep your sales receipt in a safe place.
A. LOUD Technologies Inc. warrants all materials, workmanship and proper operation of this product for a period of one
year from the original date of purchase. You may purchase
an additional 24-month Extended Warranty (for a total of 36
months of coverage). Visit our website and follow the “Product
Registration” links for details (www.mackie.com). If any defects
are found in the materials or workmanship or if the product
fails to function properly during the applicable warranty period,
LOUD Technologies, at its option, will repair or replace the
product. This warranty applies only to equipment sold and delivered within the U.S. and Canada by LOUD Technologies Inc. or
its authorized dealers.
B. For faster processing (not to mention a free gift), register
online or mail in the product registration card.
C. Unauthorized service, repairs, or modification of Mackie
products will void this warranty. To obtain repairs or replacement under warranty, you must have a copy of your sales
receipt from the authorized Mackie dealer where you purchased the product. It is necessary to establish purchase date
and determine whether your Mackie product is within the
warranty period.
D. To obtain warranty repair or replacement:
1. Call Mackie Technical Support at 800/898-3211, 7 AM
to 5 PM Monday through Friday (Pacific Time) to get authorization for repair or replacement. Alternately, go to the
Mackie website, click “Support” (www.mackie.com/support), and follow the instructions for reporting a warranty
issue and submitting a request for an advance replacement.
2. Advance Replacement: Mackie will ship a replacement
unit to you along with an invoice for the suggested retail
price of the replacement unit. You must return the defective unit immediately to cancel the invoice. If you do not
return the defective unit within 30 days, you must pay the
full amount stated in the invoice to satisfy your debt.
3. Repair: When you call Mackie Technical Support, explain the problem and obtain a Service Request Number.
Have your Mackie product’s serial number ready. You
must have a Service Request Number before you can
obtain factory-authorized service.
• 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
showing, your daytime phone number and return street
address (no P.O. boxes or route numbers, please!), and
the Service Request Number. If we cannot duplicate the
problem or establish the starting date of your Limited
Warranty, we may, at our option, charge for service time
and parts.
• Ship the product in its original shipping carton, freight
prepaid to the authorized service center. Write the Service Request Number in BIG PRINT on top of the box.
The address of your closest authorized service center
will be given to you by Technical Support, or it may be
obtained from our website. Once it’s repaired, the authorized service center will ship it back by ground shipping,
pre-paid (if it qualified as a warranty repair).
Note: Under the terms of the warranty, you must ship or
drop-off the unit to an authorized service center. The return ground shipment is covered for those units deemed
by us to be under warranty.
Note: You must have a sales receipt from an authorized
Mackie dealer for your unit to be considered for warranty
repair.
IMPORTANT: Make sure that the Service Request Number
is plainly written on the shipping carton. No receipt, no warranty service.
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 Technologies may,
at our option, require proof of the original date of purchase in
the form of a dated copy of the original dealer’s invoice or sales
receipt. Final determination of warranty coverage lies solely
with LOUD Technologies.
F. Any products returned to one of the LOUD Technologies
factory-authorized service centers, and deemed eligible for
repair or replacement under the terms of this warranty will be
repaired or replaced. LOUD Technologies and its authorized
service centers may use refurbished parts for repair or replacement of any product. Products returned to LOUD Technologies
that do not meet the terms of this Warranty will not be repaired
unless payment is received for labor, materials, return freight,
and insurance. Products repaired under warranty will be
returned freight prepaid by LOUD Technologies to any location
within the boundaries of the USA or Canada.
G. LOUD Technologies warrants all repairs performed for 90
days or for the remainder of the warranty period. This warranty
does not extend to damage resulting from improper installation, misuse, neglect or abuse, or to exterior appearance. This
warranty is recognized only if the inspection seals and serial
number on the unit have not been defaced or removed.
H. LOUD Technologies assumes no responsibility for the timeliness of repairs performed by an authorized service center.
I. This warranty is extended to the original purchaser. This
warranty may be transferred to anyone who may subsequently
purchase this product within the applicable warranty period for
a nominal fee. A copy of the original sales receipt is required to
obtain warranty repairs or replacement.
J. This is your sole warranty. LOUD Technologies does 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.
K. THE WARRANTY GIVEN ON THIS PAGE IS THE SOLE
WARRANTY GIVEN BY LOUD TECHNOLOGIES INC. AND
IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS AND
IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
WARRANTY GIVEN ON THIS PAGE SHALL BE STRICTLY
LIMITED IN DURATION TO ONE YEAR FROM THE DATE OF
ORIGINAL PURCHASE FROM AN AUTHORIZED MACKIE
DEALER. UPON EXPIRATION OF THE APPLICABLE WARRANTY PERIOD, LOUD TECHNOLOGIES INC. SHALL HAVE NO
FURTHER WARRANTY OBLIGATION OF ANY KIND. LOUD
TECHNOLOGIES INC. SHALL NOT BE LIABLE FOR ANY
INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES
THAT MAY RESULT FROM ANY DEFECT IN THE MACKIE
PRODUCT OR ANY WARRANTY CLAIM. Some states do not
allow exclusion or limitation of incidental, special, or consequential damages or a limitation on how long warranties last,
so some of the above limitations and exclusions may not apply
to you. This warranty provides specific legal rights and you may
have other rights which vary from state to state.
