9. Servicing The user should not attempt to service this Mackieproduct beyond those means described in this operating manual. All otherservicing should be referred to the Mackie Service Department.
10. Exposure to extremely high noiselevels may cause permanent hearing loss.Individuals vary considerably in susceptibil-ity to noise-induced hearing loss, but
nearly everyone will lose some hearing ifexposed to sufficiently intense noise for aperiod of time. The U.S. Governments Occupational Safety and HealthAdministration (OSHA) has specified the permissible noise levelexposures shown in the following chart.
According to OSHA, any exposure in excess of these permissible limitscould result in some hearing loss. To ensure against potentially dangerous ex-posure to high sound pressure levels, it is recommended that all personsexposed to equipment capable of producing high sound pressure levels usehearing protectors while the equipment is in operation. Ear plugs or protectors inthe ear canals or over the ears must be worn when operating the equipment inorder to prevent a permanent hearing loss if exposure is in excess of the limitsset forth here.

INTRODUCTION
The Crossover
This unique Low Impedance Compen-sated Crossover (LICC) design placesinductors in series with the woofer whosevalues are markedly lower than conven-
tional designs. This reduces the amount ofenergy that is typically wasted as heat andincreases the amount of energy that istransformed into real acoustic power. It alsoincorporates dynamic protection for thecompression driver from non-linear signals.
The Cabinet
The C300 cabinet was designed to be thestrongest molded composite cabinet on theplanet. This material is as strong as con-crete, and rigid enough to prevent
unwanted vibrations and standing waves inthe cabinet. It has built-in fly points for
hanging, and a socket in the bottom formounting on a tripod stand. Although it isan exceptional choice for installed soundsituations, its light weight and durable fin-ish also make it ideal for portable soundsystem use. The asymmetrical trapezoidaldesign of the cabinet also makes it easy touse as a floor wedge for stage monitor appli-cations.
The C300 offers a portable, lightweightsolution for a variety of high-poweredsound reinforcement applications.
Inputs
The C300 input is a Speakon connector,wired as follows:
Pin 1+ is Positive (+)Pin 1 is Negative ()(Pins 2 and 2+ are not used)
The C300i input is 1/4 TS (tip-sleeve),wired as follows:
The Tip is Positive (+)
The Sleeve is Negative ()Having these inputs on the C300i
speakers makes them an ideal choice foruse with one of our PPM-series profes-sional powered mixers.
Thank you for choosing Mackie Designssound reinforcement speakers.
The C300 has a Speakon input, and theC300i has a 1/4 inch phone jack. Apartfrom this difference, all details in this
manual apply to both models.The C300 is a portable two-way loud-
speaker system, capable of extremely highsound pressure levels, and designed to giveyou the best performance of any loudspeakerin its class and price range.
Mackie Designs entry into the soundreinforcement loudspeaker market beganwith the acquisition of Radio Cine Forniture(RCF), headquartered in Reggio Emilia,Italy. RCF has a long tradition in develop-ing speaker technology for the high-endpro-audio market.
The Transducers
The C300 features a 12 high-powerlow-frequency woofer and a 1.75 mylardiaphragm high-output compression driver.The woofer incorporates technology usedin large-format touring systems and, with amassive, precision 3-inch voice coil, is virtu-ally indestructible.
The high-frequency compression driveris mounted on a multi-cell aperture loadedon a constant directivity horn, providing an
ultra-wide, controlled dispersion pattern andprecise reproduction of the critical uppermid-range and high-frequencies. The resultis an unbelievably smooth off-axis responsethat allows everyone in the audience to ex-perience the same high-resolution audio nomatter where they are seated.
Each driver has been specifically designedby our engineers for optimum performancein a lightweight high-strength cabinet.

The C300 can beused with a MackieSRS1500a Subwoofer tocreate an incrediblypowerful system.
The active crossoverinside the SRS1500asplits the full-rangestereo input signal intotwo ranges. TheSRS1500a sums the leftand right low-frequencyrange and plays itthrough its 600 wattamplifier and 15-inch
woofer. It sends thestereo high-pass rangeto the C300s, via an ex-ternal power amplifier.

PLACEMENTThe C300 loudspeakers are designed to
sit on the floor, a tabletop, or to fit on astandard tripod speaker stand. They canalso be suspended by the rigging points,shown here.
You can lay the cabinet down on its side
and use the C300 as a floor monitor. Theasymmetrical trapezoidal shape of the cabinetprovides a perfect angle for aiming up towardperformers from the front of the stage.
Warning:Do not stackspeakers in a column.This is to avoid thedanger of topplingspeakers.
As with any loudspeakers, protect themfrom moisture. If you are setting them upoutdoors, make sure they are under cover ifyou expect rain.
Room Acoustics
The C300 loudspeakers are designed tosound as neutral as possible; that is, to re-produce the input signal as accurately aspossible, monitoringthe audio signal ratherthan changing it.
Room acoustics play a crucial role in theoverall performance of a sound system.However, the wide high-frequency dispersionof the C300 helps to minimize the problemsthat typically arise.
Top
900Dispersionup to 18kHz
900
Here are some other placement tips: Avoid placing loudspeakers in the
corners of a room. This increases thelow frequency output and can cause thesound to be muddy and indistinct.
Avoid placing loudspeakers against awall. This, too, increases the lowfrequency output, though not as muchas corner placement. However, if you doneed to reinforce the low frequencies,this is a good way to do it.
Avoid placing the speakers directly on ahollow stage floor. A hollow stage can
resonate at certain frequencies, causingpeaks and dips in the frequency re-sponse of the room. Its better to placethe loudspeakers on a sturdy table ortripod stands.
Position the loudspeakers so the high-frequency drivers are 2 to 4 feet aboveear level for the audience (make allow-ances for a standing/dancing in theaisles audience). High frequencies are
highly directional and tend to be absorbedmuch easier than lower frequencies. Byproviding direct line-of-sight from the
loudspeakers to the audience, youincrease the overall brightness andintelligibility of the sound system.
Highly reverberant rooms, like manygymnasiums and auditoriums, are anightmare for sound system intelligibil-ity. Multiple reflections off the hardwalls, ceiling, and floor play havoc withthe sound. Depending on the situation,you may be able to take some steps tominimize the reflections, such asputting carpeting on the floors, closing
draperies to cover large glass windows,or hanging tapestries or other materialson the walls to absorb some of the sound.
However, in most cases, these remediesare not possible or practical. So what doyou do? Making the sound system
louder generally doesnt work becausethe reflections become louder, too. The
best approach is to provide as muchdirect sound coverage to the audience aspossible. The farther away you are fromthe speaker, the more prominent will be
the reflected sound.Use more speakers strategically placedso they are closer to the back of theaudience. If the distance between thefront and back speakers is more thanabout 100 feet, you should use a delayprocessor to time-align the sound.(Since sound travels about 1 foot permillisecond, it takes about 1/10 of asecond to travel 100 feet.)

Poor bass performance
Check the polarity of the connectionsbetween the amplifier and the loud-speakers. You may have your positiveand negative connections reversed atone end of one cable.
It hurts when I touch my arm, or my leg,or even my head!
You have a broken finger.
Bad sound!
Is it loud and distorted? Follow theprocedures described in the QuickStart section to verify that the levelsare set properly.
Are all the connections are secure? Its agood idea to periodically clean allelectrical connections with a non-
lubricating electrical contact cleaner.
Keep practicing.
Repair
Service for the C300 is available onlyfrom one of our authorized domestic ser-vice stations or at the factory, located insunny Woodinville, Washington. Service for
loudspeakers living outside the UnitedStates can be obtained through local dealersor distributors.
If your Mackie loudspeaker needs ser-vice, follow these instructions:1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883,7am to 5pm PST, to explain the problemand request an RA (Return Authoriza-tion) number. Have your speakersserial number ready. You must have anRA number before you can obtain
service at the factory or an authorizedservice center.
3. Keep this owners manual. We dontneed it to repair the loudspeaker.
SERVICE INFO
Warranty Service
Details concerning Warranty Service arespelled out on page 11 of this manual.
If you think your loudspeaker has aproblem, please do everything you can to
confirm it before calling for service, includ-ing reading through the followingTroubleshooting section. Doing so mightsave you from being deprived of yourMackie loudspeaker.
Of all Mackie products returned for ser-vice (which is hardly any at all), many arecoded CND Could Not Duplicate,which usually means the problem lay some-where else in the system. These may soundobvious to you, but here are some thingsyou can check:
Troubleshooting
No sound!
Are the level controls on the mixer oramplifier turned all the way down?Follow the procedures in the QuickStart section on page 4 to verify that allthe volume controls in the system areproperly adjusted.
Is the signal source working (and making
union scale)? Make sure all the connect-ing cables are in good repair and securelyconnected at both ends.
One side is way louder than the other!
Are the level controls set the same forboth channels on the mixer and ampli-fier?
Check the PAN control on the signalsource. It may be turned too far to oneside. If youre using a stereo signalsource, it may be delivering an out-of-
balance stereo signal.
Try swapping sides: Switch the speakercables coming from the amplifier at theamplifier end. If the other side is loudernow, the problem is with the amplifier,the mixer, or the signal source.

CARE ANDMAINTENANCE
Your Mackie loudspeakers will providemany years of reliable service if you followthese simple guidelines: Avoid exposing the loudspeakers to
moisture. If they are set up outdoors, be
sure they are under cover if you expectrain.
Avoid exposure to extreme cold (belowfreezing temperatures). If you mustoperate the loudspeakers in a coldenvironment, warm up the voice coilsslowly by sending a low-level signalthrough them for about 15 minutesprior to high-power operation.
Use a damp cloth with a mild soapsolution to clean the cabinets. Avoidgetting moisture into any of the open-
ings of the cabinet, particularly wherethe drivers are located.
4. Pack the loudspeaker in its originalpackage, including protective wrap,endcaps and box. This is very impor-tant.Do not use styrofoam peanuts!When you call for the RA number,please let Tech Support know if youneed new packaging. Mackie is notresponsible for any damage that occurs
due to non-factory packaging.5. Include a legible note stating your name,shipping address (no P.O. boxes),daytime phone number, RA number,and a detailed description of the prob-
lem, including how we can duplicate it.
6. Write the RA number in BIG PRINTon top of the box.
7. Ship the loudspeaker to us. We recom-mend United Parcel Service (UPS). Wesuggest insurance for all forms ofcartage. Ship to this address:
Mackie DesignsSERVICE DEPARTMENT16220 Wood-Red Rd. NEWoodinville, WA 98072
8. Well try to fix the loudspeaker withinthree business days. Ask Tech Supportfor the latest turnaround times whenyou call for your RA number. Wenormally send everything back prepaidusing UPS BLUE (Second Day Air).However, if you rush your loudspeakerto us by Next Day Air, well treat it inkind by shipping it back to you UPSRED (Next Day Air).
