INTRODUCTIONIn short, all the complex interconnected

components in the system are designed to workin harmony with each other to produce the bestpossible sound.

The Transducers...The monitors feature an 8.75-inch die-cast

magnesium frame woofer and a 1-inch viscousedge-damped aluminum-alloy dome tweeter onthe front, and a 6-inch x 12-inch elliptical flatpiston passive radiator in the back.

The high-frequency driver is mounted on amassive, acoustically non-resonant die-cast zincexponential waveguide which results in wide,controlled dispersion of high-frequency sounds.The unique passive radiator design provides asmooth response down to 39Hz — an astoundingaccomplishment for a cabinet of this size! Andsince the radiator is producing most of the sound atthe lowest frequencies, there is very little distortionfrom the woofer because its cone movement isminimal at those frequencies.

The Cabinet...The cabinet is made of MDF wood. An internal

“H” brace further increases the strength and rigid-ity (stiffness) of the box. An open-cell adiabaticfoam material fills the inside of the box to absorbinternal reflections and dampen standing waves.

FR Series Power Amplifiers...What better way to power the loudspeakers

than with our acclaimed FR Series “Fast Recovery”power amplifiers. Our Fast Recovery design useslow negative feedback, yet allows the amplifiersto maintain low distortion and stability evenwhen driven into clipping.

The low-frequency amplifier produces up to150 watts continuous (350 watts peak) beforeclipping, while the high-frequency amplifier producesup to 100 watts continuous (210 watts peak).

Thank you for choosing Mackie Designs’HR824 Studio Monitors. We realize that monitorsare a critically important tool whether your appli-cation is studio recording, audio/video postproduction, hi-fi, or home theater. Knowing this,Greg Mackie had a simple mandate: Design a refer-ence monitor with a degree of accuracy andversatility unmatched by any other in its size andprice category — or any size and price categoryfor that matter. The mandate was simple, butaccomplishing it was another story!

Investments in Excellence...To accomplish the task at hand, Greg and the

New Product Development team realized that acommitment was required in terms of new resourcesand new equipment. So we recruited some of thebest speaker and acoustic engineers in the indus-try to assist in the design of the HR824. And weinvested in some advanced (and need we sayexpensive) measurement and analysis tools forthe design team to use.

The result? The HR824 Studio Monitors areextremely accurate and versatile, loaded withunique controls that allow you to fine-tune thesound to match your individual environmentprecisely. You’re gonna love these!

What are they? The Advantages...The HR824 Studio Monitors are high-resolution,

two-way, bi-amplified, active monitors employinga 6th-order Butterworth system with a built-inrear-firing mass-loaded passive radiator. Whew!There are many benefits to integrating an activecrossover, power amplifiers, and drivers into asingle cabinet, and we’ve taken full advantage ofthese benefits in the design of the HR824.• The crossover point is designed so that the

high and low frequency drivers are fed onlythe frequencies they are best able to reproduce.

• The amplifiers are designed to providemaximum acoustic output from the speakers,yet minimize the danger of speaker damagedue to overdriving.

• In addition, the amplifiers’ gain and fre-quency responses are individuallyhand-trimmed to compensate for typicalmanufacturing tolerances between thedrivers and produce a smooth frequencyresponse from 39Hz to 20kHz (±1.5 dB).

• The connecting wire between the amplifieroutputs and the drivers are kept to anabsolute minimum, so the damping factor ofthe amplifier isn’t compromised by theresistance of long speaker cables.

• The acoustic sum of the outputs from the twodrivers are optimized electronically, as well asphysically, so the amplitude response is unityand the phase difference is minimal.

1. Connect the line-level monitor signal fromyour mixer (or other signal source) to theSIGNAL INPUT jack on the HR824Studio Monitor (1⁄4-inch TRS, XLR, or RCA).

2. Connect the supplied AC power cord to theIEC socket on the back of the monitor.Plug the other end into an AC outlet properlyconfigured with the correct voltage for yourparticular model.

3. Set the POWER MODE switch on therear panel to the ON position. With thepower switch on the front panel in thedown position, the power amplifier is inStandby mode.

4. Start your signal source (tape deck, CD,DAW, or whatever), but leave the masterlevel control on your mixer down.

5. Set the power switch on the front of theHR824 to the ON position. The red PWR

LED will turn on.6. Slowly turn up the INPUT SENSITIVITY

control on the back of the monitor to itsfully clockwise position (NORMAL).

7. Adjust the master volume on your mixer toa comfortably loud listening level. Enjoy thesilky smooth highs and authoritative,commanding lows of the HR824. Then readthe rest of this manual…especially thefollowing:

QUICK START.We realize that you can’twait to hook up your newMackie Designs HR824High Resolution StudioMonitors and try them out.

Nevertheless, please take the time to read thispage NOW, and the rest can wait until you’regood and ready.

Each of the HR824 cabinets has its own built-in power amplifiers. That’s right, two amplifiersper speaker cabinet; one for the high-frequencytweeter and one for the low-frequency woofer.You should turn the INPUT SENSITIVITY control on the back of the cabinet down (fullycounterclockwise) before turning on the StudioMonitors for the first time. Also be sure to setthe power switch on the front panel to itsstandby position (down). This will prevent youfrom accidentally connecting a hot signal sourceto the monitors and getting a rude surprise.

There are a number of other settings youcan make on the back of the HR824, and youcan look at the graphic instructions relating toeach of them on the back of the cabinet (orwait until you read about them later on in thismanual so you really know what they do). Fornow, just leave them at the factory default set-tings (ACOUSTIC SPACE = WHOLE; LOWFREQ = 37Hz; HIGH FREQ = 0), except forthe POWER MODE switch. Be sure it is setto the STANDBY position.

Additional Tidbits of Wisdom• When you shut down your equipment, turn

off the HR824 studio monitors first toprevent thumps and other noises generatedby any upstream equipment from comingout the speakers. When powering up, turnon the monitors last.

• Save the shipping box! You may need itsomeday, and you don’t want to have to payfor another one.

• Save your sales receipt in a safe place.• Also record both HR824 serial numbers in

the space provided on the inside frontcover, along with where and when youbought them.

PlacementThe HR824s were designed to be placed in a

vertical position. If you find it necessary toplace the speakers in a horizontal position (ontheir sides), place them so that the woofers aretoward the inside; that is, so the woofers areclosest to each other. This provides the bestlow-frequency summing and overall imaging.

AN EXTREMELY IMPORTANT NOTEON HR824 BASS RESPONSE ANDYOUR CONTROL ROOM.

Your new HR824s achievetheir best bass response ina room that’s optimized forbass reproduction. A lot offactors can conspire to

thwart the HR824s’ extended low frequency —including room shape, room volume andacoustical treatment.

This is not a cop-out or an apology. It’s plainold physics in action. Luckily we’ve armed youwith some compensating controls which youcan use to optimize the frequency response ofthe speakers in your particular room. Considerthe following:

The ACOUSTIC SPACE switchmust be set correctly.

When you put your HR824s in a corner orup against walls, their bass characteristicschange. Adjust the ACOUSTIC SPACE switch setting accordingly to avoid muddy orexaggerated low frequency response.

Feel free to experiment.In many respects, every control room is

unique in terms of its acoustics.Even after you’ve read about how to set the

HR824’s rear panel switches, try other settingsto see if your particular room environmentrequires different adjustments.

And, even after you’ve placed your monitorswhere you think they’ll sound best, try movingthem around. You might be pleasantly surprised.

Finally, keep an open mind aboutimproving your room’s acousticsand bass-handling ability.

Nobody likes to buy a new set of monitorspeakers and then be told that they shouldspend extra bucks on bass traps or a remodelingjob. But the simple fact is, “standard” rooms,i.e. rectangular rooms in conventional businessor residential structures, are rarely if everconducive to optimal low bass reproductionwithout some modifications.

Luckily, there are plenty of options short ofbuilding a new control room, many of whichare covered in this manual.

A Few Words About THX® pm3™Certification

Nearly two decades ago, George Lucasturned a passion for great sound into theworld’s most accepted and trusted solution forachieving it. The standard was named THX(for Tomlinson Holman, who developed theTHX Sound System when he was the researchand technical director at LucasArts® in theearly 80s), and today, with hundreds of thou-sands of home theater customers and morethan 3000 THX Certified movie theaters enjoy-ing its benefits, the THX name has becomenothing short of legendary. Simply put: when itcomes to premium sound, no other name soclosely defines ‘quality’ for millions of movie-goers and home theater enthusiasts alike.

Today, a new landscape is emerging. A land-scape comprised of hundreds of small,professional multi-channel facilities, whoseneed for differentiation, expert technical andmarketing support, and a true, multi-channelstandard is becoming a competitive fact of life.Again, THX has a singular solution and thistime it’s called THX pm3 Certification.

All facilities involved with mixing and/ormonitoring of multi-channel material shouldhave the option to use pm3. THX pm3 Certifi-cation is ideal for DVD mastering, sweetening,and mixing; and is also perfect for facilities do-ing work in broadcast, music, or multi-mediaapplications.

HR824 THX pm3 Certification

When we submitted the HR824s for THXpm3 Certification, they passed on the first trywith no modifications!

Anyone seeking THX Certification for theirstudio, or striving to maintain THX standards,can use the HR824s and rest assured that theirfacility is in full compliance. (Celebrating witha jumbo Bucket ‘o Popcorn with extra butter ishighly recommended!)

INPUT SENSITIVITY

–10dB

The HR824 expects a line-level signal at itsinput connectors.• The reference sensitivity is –7.5 dBu=100 dB

SPL at one meter (39 inches) with the INPUTSENSITIVITY control set to its NORMALposition (in other words, wide open).

• The HR824 is designed to operate with a+4 dBu signal when the INPUT SENSITIVITYcontrol is in the NORMAL position.

• Refer to the QUICK START section onpage 4 for the level-setting procedure.

ACOUSTIC SPACEThis is a three-way switch that adjusts the

low-frequency response of the speakers to com-pensate for their placement in the room.

ACOUSTIC SPACE

A B CWHOLE

(NORMAL)

• If you place the HR824 monitors against awall (half space ), set the ACOUSTICSPACE switch to the “B” position. Thisactivates a shelving filter to reduce the low-frequency output by 2 dB to compensate forthe half-space placement.

• If you place the monitors into the cornersof your room (quarter space ), the low-frequency output approximately doublesfrom what it is in half space. Set theACOUSTIC SPACE switch to the “A”position to reduce the low-frequencyoutput by 4 dB to compensate for thequarter-space placement.

• If you use the HR824s free-standing, awayfrom walls and corners (whole space ),set the ACOUSTIC SPACE switch to the “C”position (NORMAL).

This is where you connect your signal to themonitor, and make adjustments to the frequencyresponse of the speakers to match the monitor’slocation and your room’s environment.

SIGNAL INPUTSThe location of the signal input jacks makes

the connectors exit down and not straight outthe back of the enclosure. This flush-mount de-sign allows you to place the monitor right upagainst the wall if desired.• XLR female, TRS female, and RCA female

connectors, parallel connected.• Don’t connect more than one source to the

jacks.• You can use the remaining jacks as “Thru”

jacks for daisy-chaining the signal toanother monitor or to another amplifier. Ifyou do this, be aware that unbalancing thesignal anywhere along the chain does so forall devices connected to the chain. Thisnegates the benefits associated withbalanced lines and inputs.

• Unbalanced TS (tip-sleeve) lines can beaccommodated via the TRS jack. Make surethe cable terminates with a TS plug (like aguitar plug), or if it’s a TRS plug (such as aheadphone plug), make sure the ring is tiedto the sleeve and that the plug is fullyinserted into the jack.

• When using a TS or TRS plug, make sure itis pushed all the way into the jack. Par-tially inserting the plug into the jack couldresult in a drop in signal level (by 6 dB).

• The XLR and TRS input connectors acceptbalanced or unbalanced signals. Theconnectors are wired as follows (per theAES/IEC standard):

XLR TRS RCAHot (+) Pin 2 Tip TipCold (–) Pin 3 Ring —Shield (Ground) Pin 1 Shield Shield

• The HR824s can be used with a homereceiver even if the receiver lacks a preampoutput by using a speaker-level to line-levelsignal attenuator. (See page 13 for moreinformation.)

somewhat. Low-frequency information requiresthe largest amount of an amplifier’s output, sorestricting the low-frequency content allowsraising the mid-frequency level somewhat. Ifyour client insists on mixing LOUD, this may bea workable strategy.

HIGH FREQ

–2dB +2dB

The HIGH FREQ switch tailors the overallhigh-frequency response by ±2 dB at 10kHz.Leave this switch in the 0 (NORMAL) positionunless:• You want to subtly brighten or darken the

sound of the speakers.• Perhaps you have hearing loss caused by

too many nights in front of a doubleMarshall stack.

• You just like to mix on the bright side ordull side.If your mixes consistently sound dull or dark

when you listen elsewhere, this usually indicatesthat your monitors are too bright, relative toyour normal hearing. A bit less high-frequencyenergy usually fixes this, and you can force themix in this direction by reducing the high-frequency output of the monitors by usingthe –2 dB position of the switch.

LOW FREQ

37Hz80Hz 47HzLOW CUT (NORMAL)

The LOW FREQ switch inserts a steep low-frequency rolloff into the response curve.• For many applications, the low-frequency

output of the HR824 may impair your abilityto make mix judgements.

• For most applications, use the 47Hz setting.• If you want or need the extra low-frequency

capability, by all means use the 37Hz(NORMAL) position.

• The LOW FREQ switch affects the low-frequency content of your mix. Rememberhow things work in reverse, so removing thedeep bass content on playback may actuallyincrease it in the final mix.

• You can use the LOW FREQ switch’s 80Hzposition to simulate a smaller loudspeaker,especially one with limited low-frequencycapability (like a certain popular 2-waynearfield monitor). You may need to do thisif a small speaker is the eventual destina-tion of your mix, or perhaps just to see howyour mix sounds on a clock radio.Removing the low-frequency content also

allows you to raise the overall output level

Conversely, if your mixes are consistentlytoo bright, then adding some additional highfrequency energy in the monitors satisfies yourears, and the resultant mix has less HF content.

The timbre of your monitorsaffects the way that yourmixes play on other equip-ment. Remember that themonitors have a mirroring

effect on the mix; if the monitors make some-thing too loud in the mix it usually results innot enough of that thing on tape.

Start with the response modificationswitches in the factory recommended settings(see Quick Start Section ). After prolongedlistening, if you notice a trend in your mixes,perhaps making some small adjustments assuggested here will help.

It’s a real rush to mix really loud. But re-member that the resulting mix only soundsgood when you play it at least that loud. How-ever strange it may sound, mixes made atlower levels sound even better when playedloud; perhaps even a bit bigger than life.

Get that sound level meter out. Decide whatlevel you’re going to mix at and use the meterto help keep your mixing at that level. Yourears will thank you, and your mixes will bebetter for it.

The HR824 is a bass reflex 6th-order system.Rather than use ports, the vent takes the formof a passive radiator, a mass-loaded flat pistoncoupled to the air trapped within the enclo-sure. You can’t see the passive radiator becauseit is located at the rear of the cabinet, behindthe power amplifier assembly.• Simple ports or ducts must have sufficient

surface area to prevent the velocity of theair within them from exceeding 5% of thespeed of sound, which keeps the vent frombecoming audible (breathing and wheezingsounds) at high signal levels.

• This requirement for sufficient surface areacreates a design problem when using ports —finding enough space in the enclosure forthem to fit.The passive radiator replaces the port found

on most speaker systems. It offers several ad-vantages to simple porting:• One primary advantage is that a passive

radiator can reproduce low frequencieswith lower distortion and at a higher soundpressure level (SPL) than a simple port orduct.

• Our unique passive radiator design uses adiaphragm made with a composite honey-comb material providing exceptionalstiffness to the radiating surface.

• The elliptical shape of the passive radiatortakes up nearly the entire surface areaavailable on the rear of the enclosure,allowing the passive radiator to move moreair than a port.

input signal level of –45 dBu (minimum)activates the auto-on function. A silentperiod greater than five minutes activatesthe auto-off function. The red PWR LEDon the front panel reflects the state of theamplifiers.

MAINS INPUTConnect the power cord to this IEC socket, and

plug the other end into your AC outlet.• When the POWER MODE switch is in

the ON position, and the power switchis in the ON position, applying AC poweractivates the muting circuit for about fourseconds while the power supply andinternal circuitry stabilize.

PASSIVE RADIATORWhen you mount a loudspeaker in a box,

there are two things that you can do with theradiation from the rear of the cone: use it toenhance the low-frequency performance of thespeaker system (bass reflex system) or soak itup (acoustic suspension system).• A bass reflex system uses the rear radiation

to extend the low-frequency response. Mostsystems provide holes (ports) in the frontor back of the cabinet to release the rearwave. Sometimes the holes have tubes(ducts) in them. The dimensions of theholes and the volume of the cabinet workwith the characteristics of the woofer toproduce low-frequency extension. Thesesystems are characterized by good low-frequency performance down to the –3 dBfrequency set by the design. Below thisfrequency, the frequency response falls at24 dB/octave or more.

FRONT PANEL DESCRIPTION

Overload ProtectThe high and low frequency power amplifiers

have clipping detectors that light the OL LEDwhen either power amplifier output clips.• If you see the OL LED blinking more than

just occasionally, it’s an indication that youshould reduce the signal level coming fromyour mixer or other signal source.

• If frequent clipping continues, the driverthermal overload protection activates acompressor that reduces the input level tothe amplifiers. During this time the OLLED lights continuously.

• The compressor was designed to protectthe speakers and its action is highlyaudible.

• The compressor was not designed formixing!

If a client insists on listeningto the monitors at a very highvolume, you may find thatthe OL LED lights frequently.Since the majority of the

power requirement in any monitor are the lowfrequencies, selectively reducing the low endcan provide a little more headroom and volumefor the monitors. Change the LOW FREQ switch to 47Hz or 80Hz, if necessary, to reducethe bass response. This may allow the HR824sto play just enough louder to satisfy the clientand to eliminate most of the amplifier clipping.

Power SwitchUse this switch to turn on or off the HR824

from the front. It works with the POWERMODE switch on the rear panel in thefollowing way:• If the POWER MODE switch on the rear

panel is set to STANDBY, the front panelpower switch has no effect. The PWR

LED remains off.• If the POWER MODE switch is ON, the

front panel power switch turns the HR824on or returns it to STANDBY mode, asindicated by the PWR LED.

• If the POWER MODE switch is in theAUTO ON position, the front panel powerswitch turns the HR824 on, even when thereis no signal present. If there is no signal afterabout two minutes, the auto-off function isactivated and the amplifiers go into Standbymode, indicated when the red PWR LEDgoes off.

OL (Overload) LEDThis LED blinks when the amplifiers begin

to clip and lights steadily if the overload protec-tion circuit has been triggered.• Occasional blinking of the OL LED indicates

that the loudest transients are reaching themaximum output capability of the amplifiers.This is okay.

• Frequent or continuous blinking of the OLLED indicates that you have exceeded themaximum output capability of the amplifiersand that the amplifiers are clipping. If youpersist, the overload protection circuit takesover, reducing the input level. You shouldreduce the level from your signal source untilthe OL LED blinks occasionally or not at all.

PROTECTION CIRCUITSThere are a number of protection mecha-

nisms designed into the HR824 to safeguardthe loudspeakers from inadvertent damage.

CAUTION: The protection circuits are de-signed to prevent damage to the loudspeakersunder reasonable and sensible conditions.Should you choose to ignore the warning signs(i.e., frequent Overload LED indications, ex-cessive distortion), you can still damage thespeakers in the HR824 by overdriving thempast the point of amplifier clipping. Such dam-age is beyond the scope of the Warranty.

13

Thermal ProtectAll amplifiers produce heat. The HR824 is

designed to be efficient both electrically and ther-mally.• If for some reason the heatsinks get too hot,

a thermal switch activates, placing theHR824 into Standby mode (indicated whenthe red PWR LED turns off).

• Should this happen, make sure that airflowto the rear of the cabinet is not restricted.

• When the heatsinks cool down to a safetemperature, the switch resets and normaloperation resumes.

INTEGRATED MAGNETIC SHIELDINGThe HR824 Studio Monitor contains drivers

with large magnet structures. The drivers’ mag-nets are shielded to help prevent the magneticfield from radiating out into the environmentand playing havoc with computer monitors orTV screens. Unshielded speakers can causedistortion in both the shape and color of thepicture if placed too close to a CRT (cathoderay tube). If you have a particularly sensitivecomputer monitor or TV screen, it may be nec-essary to move the speakers a few inches away.

INPUT SIGNAL WIRINGYou should use high-quality, shielded cable

to connect the signal source to the SIGNALINPUT jack on the HR824.• Foil shielded cables, such as Belden 8451,

8761, or 9501 are commonly used for studiowiring.

• Microphone cables work well.• The better the shield, the better the

immunity from externally induced noise(like EMI and RFI). Route the cable awayfrom AC power cords and outlets. These arecommon sources for hum in an audiosignal. Wall warts and line lumps areespecially insidious hum inducers!You can purchase quality cables from yourMackie dealer.

• In certain home theater applications, itmay be necessary to connect the speakeroutputs from a stereo receiver to the inputsof the HR824s, if the receiver doesn’t havepreamp outputs or other line-level outputconnections.

CAUTION: Do not attemptto connect a speaker outputdirectly to the input of theHR824! Speaker levels aremuch higher than line

levels and can damage the input circuitryin the HR824.You can, however, insert a speaker-level toline-level signal attenuator between thereceiver’s speaker output and the HR824’sinput. Your Mackie dealer may be able tohelp you find one, or you can build yourown. Contact our tech support departmentfor more information.

• If it’s a stereo pair, try switching themaround. For example, if a left output ispresumed dead, switch the left and rightcords at the monitor end. If the problemswitches sides, it’s not the monitor. It couldbe a bad cable, or no signal from the mixer.

Bad Sound• Is the input connector plugged completely

into the jack? If using a 1⁄4” TS or TRS plug,make sure it is plugged all the way in.

• Is it loud and distorted? Reduce the signallevel at the mixer.

• If possible, listen to the signal source withheadphones plugged into the preamp stage.If it sounds bad there, it’s not the monitor.

• Too much bass or not enough bass? Movearound the room and see if the bassresponse changes. It’s possible yourlistening position coincides with a roommode where the low frequencies eitherbecome exaggerated or nulled. If so, trymoving the monitors to a different position,or moving your listening position.

Noise/Hum• Check the signal cable between the mixer

and the monitor. Make sure all connectionsare secure. These problems usually producecrackling noises or hum.

• If connecting an unbalanced output to theHR824 balanced input, make sure the shieldis connected to the unbalanced ground andto pin 1 of the XLR (or the sleeve of theTRS jack).

• If a CATV cable is connected to the system,try disconnecting it. If the hum goes away,call your cable carrier to check for propergrounding of the cable.

Service InfoDetails concerning Warranty Service are

spelled out on the Warranty Card included withyour monitor (if it’s missing, let us know andwe’ll rush one to you).

If you think your monitor has a problem,please do everything you can to confirm it beforecalling for service, including reading throughthe following Troubleshooting section. Doingso might save you from deprivation of yourmonitor and the associated suffering.

Of all Mackie products returned for service(which is hardly any at all), roughly 50% arecoded “CND” — Could Not Duplicate, whichusually means the problem lay somewhere elsein the system. These may sound obvious to you,but here are some things you can check:

Troubleshooting

No Power• Our favorite question: Is it plugged in?• Make sure the power cord is securely

seated in the IEC socket and pluggedall the way into the AC outlet.

• Make sure the AC outlet is live (check witha tester or lamp).

• Are the power switch on the front paneland the POWER MODE switch on therear panel in the ON position?

• Is the PWR LED on the front panelilluminated? If not, make sure the ACoutlet is live. If so, refer to “No Sound”below.

• If the PWR LED is not illuminated, and youare certain that the AC outlet is live, it willbe necessary to have the HR824 serviced.There are no user-serviceable parts inside.Refer to “Repair” at the end of this sectionto find out how to proceed.

No Sound• Is the PWR LED on the front panel

illuminated? If not, refer to “No Power”above.

• Is the INPUT SENSITIVITY controlturned up?

• Is the signal source turned up? Make sure thesignal level from the mixing console (or what-ever device immediately precedes the studiomonitor) is high enough to produce sound.

1. Review the preceding troubleshootingsuggestions. Please.

2. Call Tech Support at 1-800-258-6883, 7 amto 5 pm PST, to explain the problem andrequest an RA (Return Authorization)number. Have your monitor’s serialnumber(s) ready. You must have an RAnumber before you can obtain service at thefactory.

3. Set aside the power cord, owner’s manual,or anything else that you’ll ever want to seeagain. We are responsible for the return ofthe monitor only.

4. Pack the monitor in its original packingbox. This is very important. When you callfor the RA number, please let Tech Supportknow if you need new packaging. Mackie isnot responsible for any damage that occursdue to non-factory packaging.

5. Include a legible note stating your name,shipping address (no P.O. boxes), daytimephone number, RA number, and a detaileddescription of the problem, including howwe can duplicate it.

6. Write the RA number in BIG PRINT on topof the box.

7. Ship the monitor to us. We suggest insur-ance for all forms of cartage. Ship to thisaddress:

Mackie DesignsSERVICE DEPARTMENT16220 Wood-Red Rd. NEWoodinville, WA 98072

8. We’ll try to fix the monitor within fivebusiness days. Ask Tech Support for currentturnaround times when you call for your RAnumber. We normally send everything backprepaid using three-day shipping. However,if you rush your monitor to us by next-dayair, we’ll treat it in kind by shipping it backthe same way in which it was received. Thisparagraph does not necessarily apply tonon-warranty service.

• Make sure the signal cable is not routednear AC cables, power transformers, orother EMI sources (including wall wartsand line lumps!). These sources usuallyproduce hum.

• Is there a light dimmer or other triac-based(SCR) device on the same AC circuit as themonitor? Dimmers cause buzzing noises.Use an AC line filter or plug the monitorinto a different AC circuit.

• Excessive hiss is an indication of anincorrect gain setting somewhere beforethe speaker.

• If possible, listen to the signal source withheadphones plugged into the console. If itsounds noisy there, it’s not the monitor.

I hear sound from the monitors after Iswitch the AC power off!• Use the front panel switch to turn the

monitors on and off, or turn off the signalgoing to the monitors when the AC power isturned off.If you unplug the HR824 or turn off the

power strip that it’s plugged into with a signalapplied to the input, you may hear sound fromthe monitor for a short period of time as themuting circuit unmutes and the power supplyfinishes discharging. This is normal and notharmful to the monitor.

RepairService for the U.S. versions of our monitors

is available only from our factory, located insunny Woodinville, Washington. (Service formonitors living outside the United States canbe obtained through local dealers or distribu-tors.) If your monitor needs service, followthese instructions:
