9. Power Sources -- This Mackie product should be connected to a power supply only of the type described in these operation instructions or as marked on this Mackie product. Power Cord Protection -- Power supply cords should be routed so that they are not likely to be walked upon or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit this Mackie product. Object and Liquid Entry -- Care should be taken so that objects do not fall into and liquids are not spilled into this Mackie product. [. . . ] We recommend that a stiff (robust) supply of AC power be used because the amplifiers place high current demands on the AC line. The more power that is available on the line, the louder the speakers will play and the more peak output power will be available for cleaner, punchier bass. A suspected problem of "poor bass performance" is often caused by a weak AC supply to the amplifiers. Never remove the ground pin on the power cord of the SR1530 or any other component. This is very dangerous.

THERMAL CONSIDERATIONS
The SR1530 has three powerful built-in amplifiers capable of producing a combined 500 watts of power. As amplifiers produce heat, it is important to dissipate the heat as quickly as possible. This results in increased reliability and longevity for the amplifier. The amplifier module is mounted on a large heatsink, which is cooled by convection where cool air is drawn through it's fins, carrying the heat away. In order for this convection cooling to work efficiently, it is important to provide adequate airspace behind the loudspeaker. When you position the SR1530, we recommend leaving at least six inches of air space behind it. In the unlikely event of the amplifier overheating, a built-in thermal switch will activate, which mutes the signal. When the amplifier has cooled down to a safe operating temperature, the thermal switch resets itself, and the SR1530 resumes normal operation. If the thermal switch activates frequently, try turning down the level control a notch or two on the mixing console (or other signal source) to avoid overheating the amplifier. If the temperature in the room is too high, it could cause the amplifier to overheat. In this case, you should try aiming a fan at the rear panel to move more air through the fins.
Troubleshooting
No power
· Our favorite question: Is it plugged in?If you suspect the AC line fuse is blown, please see the REPAIR section next.
No sound
· Is the input LEVEL control for the input source turned all the way down?Verify that all the volume controls in the system are properly adjusted. Make sure the connecting cables are in good repair and securely connected at both ends. Make sure the output volume (gain) control on the mixing console is turned up sufficiently to drive the inputs of the speaker. · Make sure the mixer does not have a Mute on or a Processor loop engaged. If you find something like this, make sure the volume/gain is turned down before disengaging the offending switch. Make sure there is at least six inches of free space behind the SR1530.
SERVICE INFORMATION
Warranty Service
If you think your loudspeaker has a problem, please do everything you can to confirm it before calling for service, including reading through the following Troubleshooting section. [. . . ] You must have an RA number before taking your unit to a service center. Make sure that you have a copy of your loudspeaker's sales receipt from the store where you bought the product. It is necessary to establish purchase date and thus determine whether or not your loudspeaker is still under warranty. If you can't find it, the Authorized Service Center may charge you for repairs even if your loudspeaker is still covered by Mackie's 1-Year Limited Warranty. [. . . ]
