INTRODUCTION  
Thank you for choosing Mackie sound rein-  
forcement loudspeakers.  
The Crossover  
This unique Low Impedance Compensated  
Crossover (LICC) design places inductors in se-  
ries 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 incor-  
porates dynamic protection for the compression  
driver from non-linear signals.  
The C300z is a portable two-way loudspeaker  
system, specifically designed to complement our  
PPM Series line of professional powered mix-  
ers. 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 large-  
format touring systems and, with a massive,  
precision 3-inch voice coil, is virtually inde-  
structible.  
The high-frequency compression driver is  
mounted on a multi-cell aperture loaded on a  
constant directivity horn, providing an ultra-  
wide, 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-reso-  
lution audio no matter where they are seated.  
Each driver has been specifically designed by  
our engineers for optimum performance in a light-  
weight high-strength cabinet.  
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 asym-  
metrical 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 rein-  
forcement 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 built-  
in amplier and 15-inch  
woofer. It sends the ste-  
reo high-pass range to the  
C300zs, via an external  
power amplier.

PLACEMENT  
The C300z loudspeakers are designed to sit on  
the oor, a tabletop, or to t on a standard tripod  
speaker stand. They can also be suspended by the  
rigging points, shown at the right (also see "Rig-  
ging" on the next page).  
You can lay the cabinet down on its side and use  
the C300z as a oor 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 speak-  
ers 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.  
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 fre-  
quencies 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 gymna-  
siums and auditoriums, are a nightmare for  
sound system intelligibility. Multiple reec-  
tions off the hard walls, ceiling, and oor  
play havoc with the sound. Depending on the  
situation, you may be able to take some steps  
to minimize the reections, such as putting  
carpeting on the oors, closing draperies to  
cover large glass windows, or hanging tapes-  
tries or other materials on the walls to absorb  
some of the sound.  
Room Acoustics  
The C300z loudspeakers are designed to sound  
as neutral as possible; that is, to reproduce the in-  
put signal as accurately as possible, monitoring the  
audio signal rather than changing it.  
Room acoustics play a crucial role in the over-  
all 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  
However, in most cases, these remedies are  
not possible or practical. So what do you do?  
Making the sound system louder generally  
doesnt work because the reections 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  
reected 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.)  
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 oor. A hollow stage can resonate at certain  
frequencies, causing peaks and dips in the fre-  
quency response of the room. Its better to place  
the loudspeakers on a sturdy table or tripod stands.

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 de-  
livered to the driver is momentarily reduced.  
CAUTION: The protection  
stops, and is characterized by a “flat-topap-  
pearance to the waveform when viewed on an  
oscilloscope.  
Normal Sine Wave Signal  
circuit is designed to protect  
the HF driver under reasonable  
and sensible conditions. Should  
you choose to ignore the warn-  
ing signs (i.e., frequent clip  
Clipped Sine Wave Signal  
LED indications, excessive distortion), you can  
still damage the speakers in the C300z by over-  
driving them past their recommended amplier  
power-handling ratings, or past the point of am-  
plier clipping. Such damage is beyond the scope  
of the warranty.  
Amplifier Power  
Clipping interrupts the motion of the trans-  
ducer, creating distortion and excessive heat in the  
driver, which can damage it over time.  
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 in-  
struments 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 amplier that is rated at twice the con-  
tinuous power rating of the loudspeaker (into 8  
ohms). For the C300z, this would be 300 watts x 2  
Some folks think that if they use a power am-  
plier whose power rating is below the maximum  
power-handling rating of the loudspeaker, then  
they cant possibly damage the loudspeaker. But if  
the amplier is driven into clipping, even a lower  
power amplier can damage the loudspeaker.  
The bottom line is that to prevent damage to  
the loudspeakers, you must have a properly oper-  
ating 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 tted with ten rigging  
points as shown in the diagram on the previous  
page. These are M10 inserts. M10 threaded eye-  
= 600 watts per channel into 8 ohms. This insures bolts (M10 x 1.5 mm x 20 mm) are available to t  
that the amplier can reproduce peaks that are 6 dB in these inserts (PA-A1 Eyebolts).  
higher than the continuous (rms) power-handling  
rating before clipping occurs.  
WARNING: Never attempt to  
suspend the C300z loudspeak-  
ers by their handles. If you  
want to suspend them, use the  
Preventing Loudspeaker Damage  
rigging points only. Consult a  
professional rigger or structural  
Speaking of clipping, this is likely the number  
one cause of damage to loudspeakers. Clipping oc-  
curs when the signal at the output of any device  
in the system (not just the amplier) reaches its  
maximum level. The input signal to the device  
may continue to increase, but the output simply  
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 ve  
times the actual load.

SERVICE INFO  
Bad sound!  
Warranty Service  
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 conrm it before  
calling for service, including reading through  
the following Troubleshooting section. Doing so  
might save you from being deprived of your Mack-  
ie loudspeaker.  
Is it loud and distorted? Follow the procedures  
described in the Quick Startsection to verify  
that the levels are set properly.  
Are all the connections secure? Its a good  
idea to periodically clean all electrical connec-  
tions with a non-lubricating electrical contact  
cleaner.  
Keep practicing.  
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 somewhere else in the sys-  
tem. These may sound obvious to you, but here  
are some things you can check:  
Repair  
Service for the C300z is available at a factory-  
authorized service center. Service for Mackie  
products living outside the United States can be  
obtained through local dealers or distributors.  
If your Mackie loudspeaker needs service, fol-  
low these instructions:  
1. Review the preceding troubleshooting sugges-  
tions. Please.  
2. Call Tech Support at 1-800-898-3211, 7 am to  
5 pm PST, to explain the problem and obtain a  
Service Request Number. Have your speakers  
serial number ready. You must have a Service  
Request Number before you can obtain fac-  
tory-authorized service.  
Troubleshooting  
No sound!  
Are the level controls on the mixer or am-  
plier turned all the way down? Follow the  
procedures in the Quick Startsection 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.  
3. Keep this owners manual. We dont need it to  
repair the loudspeaker.  
4. Pack the loudspeaker in its original package,  
including protective wrap, endcaps and box.  
This is very important. Do not use styrofoam  
peanuts! Mackie is not responsible for any  
damage that occurs due to non-factory pack-  
aging.  
5. Include a legible note stating your name, ship-  
ping 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. Products sent to us  
without the Service Request Number will be  
refused.  
7. Tech Support will tell you where to ship the  
loudspeaker for repair. We suggest insurance  
for all forms of cartage.  
One side is way louder than the other!  
Are the level controls set the same for both  
channels on the mixer and amplier?  
Check the PAN control on the signal source. It  
may be turned too far to one side. If youre us-  
ing a stereo signal source, it may be delivering  
an out-of-balance stereo signal.  
Try swapping sides: Switch the speaker cables  
coming from the amplier at the amplier end.  
If the other side is louder now, the problem  
is with the amplier, the mixer, or the signal  
source.  
Poor bass performance  
Check the polarity of the connections between  
the amplier and the loudspeakers. You may  
have your positive and negative connections  
reversed at one end of one cable.  
8. Well try to x the loudspeaker within three to  
ve business days. Ask Tech Support for the  
latest turnaround times when you call for your  
Service Request Number. The loudspeaker  
must be packaged in its original packing box,  
and must have the Service Request Number  
on the box. Once it is repaired, we'll ship it  
It hurts when I touch my arm, or my leg, or even  
my head!

You have a broken nger.  
 
back the same way in which it was received.  
This paragraph does not necessarily apply to  
non-warranty service.  
Note: You must have a sales receipt from an  
Authorized Mackie Dealer to qualify for a  
warranty repair.  
Use heavy gauge, stranded wire for connecting a  
speaker to the output of a power amplier.  
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  
amplier and can overheat.  
CARE AND MAINTENANCE  
As the distance between the amplier 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 re-  
sistance it offers, and the more power actually gets  
to the speaker.  
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 freez-  
ing 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.

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.  
B. Failure to register online or return the product  
registration card will not void the two-year warranty.  
C. Service and repairs of Mackie products are to  
be performed only at a factory-authorized facility  
(see D below). Unauthorized service, repairs, or  
modification will void this warranty. To obtain  
repairs 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.  
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.  
D. To obtain factory-authorized service:  
H. LOUD Technologies assumes no responsibility  
for the quality or timeliness of repairs performed by  
an authorized service center.

or sales receipt. Final determination of warranty  
coverage lies solely with LOUD Technologies.
