13. Unplug this device during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the device has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled, or objects
have fallen into the device, the device has been exposed to rain or moisture, does not operate normally,
or has been dropped.
15. WARNING: To reduce the risk of fire or electric shock, this device should not be exposed to rain or
moisture and objects filled with liquids, such as a vase, should not be placed on this device.
16. To completely disconnect this equipment from the mains, disconnect the power supply cord plug from
the receptacle.
17. The mains plug of the power supply cord shall remain readily operable.
1. Plugging in or unplugging the power cord with wet hands may result in electric shock.
2. Never move the device with the power cord plugged into the wall, as damage to the power cord may result.
3. When unplugging the cord from the wall, grasp the plug, NOT the cord.
4. Never install this device in humid or dusty locations, nor in direct sunlight, near sources of heat, or in
areas where sooty smoke or steam are present. Fire and electric shock may result.
5. Keep all sides of the device at least 31⁄2" away from objects that may obstruct air flow to prevent the unit's
internal temperature rise.

1. To prevent electric shock, do not remove the device cover as there are high voltage components inside.
Refer all servicing to Atlas Sound.
2. Should any of the following irregularities occur during use, immediately switch off the power,
disconnect the power cord from the AC outlet and contact Atlas Sound. Do not to attempt to continue
operation with the device as this may cause fire or electric shock:
• Smoke or strange smell coming from the unit.
• If the device falls or the case is damaged.
• If water or any metallic objects falls into the device.
• If the power supply cord is damaged in any way.
• If the device is malfunctioning.
3. Do not insert or drop metallic objects or flammable materials into the ventilation holes of the device's
cover, as this may result in electric shock or fire.
4. Do not place any containers with liquid or metallic objects on the top of the device. If any liquid spills into
the unit, fire or electric shock may result.
5. Never operate this device or touch the power supply cord during an electrical storm, electric shock
may result.
6. Never exceed the wattage on the product when connecting equipment. Fire and/or property damage
may result.
7. Operate the device only with the voltage specified on the unit. Fire and/or electric shock may result if a
higher voltage is used.
8. Do not modify, kink, or cut the power cord. Do not place the power cord in close proximity to heaters and
do not place heavy objects on the power cord, including the device itself, doing so may result in fire or
electrical shock.
9. Ensure that the safety ground terminal is connected to a proper ground. Never connect the ground to a
gas pipe as a catastrophic disaster may result.
10. Be sure the installation of the product is stable, avoid slanted surfaces as the product may fall and cause
injury or property damage.
1. Never place heavy objects on the product, causing it to fall and/or break, resulting in personal injury and
property damage. In addition, the product itself may fall and cause injury and property damage.
2. Contact Atlas Sound for instructions on cleaning the inside of the unit. Large accumulations of dust
inside the unit may result in heat buildup and fire.
3. Ensure that the power supply plug is securely plugged into the wall outlet. Never allow dust to
accumulate on the power plug or inside the wall outlet.
4. When cleaning the unit or the unit is not to be operated for an extended time period, unplug the power
cord from the wall.

Front Panel Description
1. Power LED
This LED illuminates when the AC Mains are plugged in.
2. Limit LED Indicator
The LIMIT LED will illuminate when the MA40G/MA60G is in a clipping condition, caused by excessively high input levels
or a GAIN control is turned up too high. An occasional flash is OK. Check that the proper signal level is being fed into the
inputs and/or turn the input gain down until the LED is no longer illuminated. Refer to Limit LED & Load Conditions for
more information.
3. Signal LED
When the signal LED illuminates, this indicates that input signals connected to the amplifier are capable of
driving the MA40G/MA60G to full power.

Limit LED and Load Consideration
If the Red Limit LED illuminates, the amplifier has sensed an improper load or the input signal is too high, triggering the protection
circuitry. When the load sense Limit circuitry is engaged the amp will operate but at a lower power output. It is s highly recommended
to discontinue use immediately and correct the fault condition. If you continue to operate with the RED Limit LED on, the second stage
of the current sense circuit may engage causing the amp not to pass any signal. To reset the amp turn down the Level controls and turn
the power off for 10 seconds.
In most situations when the Limit LED is in the illuminated steady state it means the speaker system load to the amp is lower than
whattheampisrated.Thisusuallyisdetectedwhenthesystemisfirstsetup.Belowareafewloadconditionstocheckforifthe
Limit LED is on.
 1. Connectedtothewrongspeakerterminal.Alwayscheckthespeakerterminaltothetypeofloadyouareusing.Example:If
  youareinstallinga70Vor100Vsystemmakesurethewiresareconnectedtothe70V/100Vandcommon(COM)terminals.
 2. Toomanyspeakersconnectedtotheamp.Thisisaverycommonmistake.Ifyouareusinga60Wampandusingthe70V
speaker terminals, add up the number of speakers and their wattage selections at the speaker. If they exceed 60W you must
retap the speakers or remove the correct amount of speaker wattage until the wattage is 60W or less. Example if you are
using a 30W tap you can only connect 2 speakers to the amp. If you are using the 7.5W tap, you can connect 8 speakers. If
you have too many speakers on the amp it will load the amp down, causing excessive current demand and will trigger the
Limit & Protect circuit.
 3. Wrongspeakertapselection.Itisalsocommonina70Vor100Vsystemthatoneofthespeakersissetattoolowofan

4. Short in system. This is common if the wire is run in metal conduit and the wire got nicked during the wire pull.
 5. SpeakerLevelControls.IfanL-PADorsteppedattenuatoriswiredwrongitcanalsoloadasystemdown.

Measuring a Speaker System's Impedance
Note:ItisimportanttoonlyuseanAudioImpedanceMeterandnotaconventionalVolt/Ohmmeter.
A true audio frequency impedance meter is essential for reliable installation of background music and paging systems in residences,
office buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior
tooperation.Unlikeconventionalvolt/ohmmeters,whichmeasureDCresistance,anAudioImpedanceMeterunitutilizesaninternal
frequencyoscillatortomeasuretrueimpedance.Itmayalsobeutilizedwith70.7Vand100Vspeakerlinetransformers,L-padsand
matching Impedance volume controls. There are several Audio Impedance meters on the market, if you need to buy one we suggest
going to MCM Electronics, Parts Express or search the internet for “Audio Impedance Meter”.
Measuring 70.7V or 100V Distributed Speaker Systems
Largedistributedsystemstypicallyutilize70.7V(NorthAmerica)or100V(Europe)typesystemtogreatlyeasetheconnectionof
multiple speakers and facilitate long cable runs. Shown below are speakers connected in parallel with wattage ratings to calculate
the overall load of the system. Connecting an Audio Impedance Meter to a speaker arrangement such as this will provide the overall
impedance of the system.
Usingthefollowingformulayoucancalculatetheloadimpedancefromthespeakerselectedwattage.Theaccumulativewattageof
the speaker system must not exceed the maximum wattage output rating of the amplifier or damage may occur. In this example the
measurementfora70.7Vdesignwiththreespeakersof15Weach,thesystemimpedancewouldmeasurecloseto111Ω. Formula
70.7Vx70.7V=4998,4998/45W=111Ω. The amplifier power requirements would be at least 60W for the system to operate
properly.Note:Itisalwaysrecommendedtousealargerampthanneededwithpowerheadroomofatleast25%.Calculatetheload

proceed connecting the load to the amplifier. If they are not recheck your speaker taps or check for shorts.
