Precautions
Verify The Line Voltage
Your new amplifier has been factory configured for 120 or 230 (+/- 3%) volt AC lines dependingonwhatcountryyoupurchaseditin.Connectingtheamplifiertoalinevoltageotherthanthatforwhichitisintendedcancreateasafetyandfirehazard,andmay damagetheamplifier.Ifyouhaveanyquestionsaboutthevoltagerequirementsforyour specificmodel,oraboutthelinevoltageinyourarea,contactAtlanticTechnologybefore pluggingtheunitintoawalloutlet.
Verify AC Circuit Capacity
Thehighpoweroutputof youramplifiermayrequireheavypowerdrawunderfullload conditions. To insure proper performance, and to avoid potential safety hazards, we recommend that it be connected to a minimum 20 Amp capacity circuit.Connecting multipleamplifierstothesamecircuit,orconnectingittoacircuitusedbyotherheavyusepowerdevices,suchasairconditioners,maycausecircuitbreakerstotrip.
NOTE:ItisalwaysagoodideatoavoidusinganyaudioorvideoequipmentonthesameAC circuitasequipmentwithmotors,suchasairconditionersorrefrigerators.Thiswilllessenthe possibility of power variation and electrical start-up noise affecting your sound system.
Extension Cords and Power Strips
We do not recommend that extension cords be used with this product unless they are of sufficientgaugetopassthenecessarycurrentduringfullloadconditions.Mostinexpensiveextensioncordsarenotcapableof suchhigh-currentloads.
Similarly, should you use a power strip, surge protector or any type of AC power line conditioning equipment, make certain that it is also able to handle the high current loadsthisproductwilldraw.
Handle the AC Power Cord Gently
Whendisconnectingthepower cordfromanACoutlet,alwayspulltheplug,neverpull the cord.If you do not intend to use the amplifier for any considerable length of time, disconnecttheplugfromtheACoutlet.If thepowercordisreplaced,makecertainthat it is of similar gauge.As with all electrical devices,do not run power cords under rugs or carpets or place heavy objects on them.Damaged power cords should be replaced immediatelywithcordsmeetingfactoryspecifications.
Wiring
Cables that are run inside of walls should have the appropriate markings to indicate compliancewith,andlistingbytheUL,CSAorotherstandardsrequiredbytheUL,CSA, NECoryourlocalbuildingcode.Questionsaboutcablesinsideofwallsshouldbereferred toaqualifiedcustomerinstaller,oralicensedelectricianorlow-voltagecontractor.

Installation Location
To assure proper operation and to avoid the potential for safety hazards,place the unit onafirmandlevelsurfacecapableof supporting100poundsormore.Whenplacingthe amplifieronashelf,becertainthattheshelfandanymountinghardwarecansupportthe weightof theamplifierandanyadditionalitemsintheequipmentrack,orontheshelf.
When positioning the amplifier in its final location,make certain that it has adequate ventilationonallsides,aswellasonthetopandbottom.Inparticular,itisagoodideato provideatleasttwoorthreeinchesof roomabovetheamplifierforaircirculation.
DO NOT place CDs, DVDs, videotapes, owner’s manuals, or other paper on top of, or beneath,the unit,or in-between multiple amplifiers in a stack.This will block airflow, causingheatbuild-up,degradedperformance,andmaycreateapossiblefirehazard.
If the unit is to be enclosed in a cabinet or rack,make certain there is adequate air circulation.Sufficient ventilation should be provided so that hot air may exit,and cool air may enter the cabinet.In some instances,a small cooling fan may be required to insure adequate airflow through the cabinet.If you are in doubt as to the ventilation requirements for your specific installation, please contact us.Also, do not place the amplifier directly on a carpeted surface,as this will inhibit airflow underneath as well as create a potentialfirehazard.

Loudspeaker Ratings
TheAtlanticA-2000hasadequatepowertodrivemostloudspeakerswithoutproducing audible distortion.Most modern speakers are rated at four to eight ohms nominal impedance,butwithinsomefrequencyranges,theimpedancemaydroptotwoohms.The A-2000isdesignedwithsubstantialpowerreservestoprotectyoufromexperiencingany problemsattheselowimpedances,unlessyoudemandexcessivelyhighvolumelevels.
Duetothehighpoweroutputcapabilityof theA-2000,itisimportantthattheamplifier not be used with speakers that aren’t capable of handling theA-2000’s power output or in a manner that could lead to speaker damage. Before using the A-2000 for the first time,makecertainthatyourspeakersarecapableof handlingitsratedpoweroutput,at the impedance rating of your speakers and that you read and understand the following importantnote.
IMPORTANT NOTE Given the right set of circumstances any amplifier is capable of damaging any loudspeaker, no matter what their respective power ratings. Damage can be done either through excessive power output to the speaker or excessive distortion from the amplifier due to clipping. Amplifier clipping is the result of asking the amplifier to deliver substantially more power than it is capable of producing without excessive distortion. This is the single most common cause of speaker damage and can happen no matter how high the power rating of the attached speakers or amplifier may be. Atlantic Technology is not responsible for damage to any speaker system or other component that is caused by using products whose power rating is lower than that of the amplifier or in a manner that results in amplifier clipping and therefore component damage.
Do Not Open The Cabinet
Therearenouserserviceablecomponentsinsidethisproduct.Openingthecabinetmay present a shock hazard,and any modification to the product will void your warranty.If wateroranymetalobject,suchasapaperclip,coinorastaple,accidentallyfallsinsidethe unit,disconnectitfromtheACpowersourceimmediately,andcontactAtlanticTechnology oryourDealer/Installerforfurtherinstructions.
IMPORTANT SAFETY NOTE
Before connecting a new component such as power amplifier to your audio or home theatersystemitisalwaysgoodpracticetomakecertainthatallcomponentsareturned off, and preferably unplugged from their AC power source.
