[. . . ] If the amplifier should overheat, a thermal switch turns off the power amplifier, allowing the heatsink to cool down. Once the amplifier has cooled to a safe operating temperature, the thermal switch resets and reactivates the amplifier. If this should occur, identify the cause of the problem and take corrective action. For example: · · · Provide better ventilation Install a fan in the rack to move more air Make sure the amplifier is not overloaded with too low of a load impedance or by a short circuit on the speaker line Owner's Manual The AC current demand of an amplifier varies dependRACK MOUNTING ing on several factors, including the load impedance, the crest factor, and the duty cycle of the program The FRS amplifiers are designed to be mounted in a material. They require two rack spaces music where musical peaks are just below clipping, the (2U = 3. 5"). They also require 14. 65" depth inside the amplifiers require the following average currents: rack, including the rear support brackets. When designing your rack, put the heavier items at the bottom and FRS·1300 = 6 A the lighter items toward the top. FRS·1700 = 8 A FRS·2800 =11 A Secure the front panel of the amplifier to the front of It is recommended that a stiff supply of AC power be the rack using four screws with soft washers to prevent used because the amplifier places high current demands scratching the panel. The more power that is available on the of the amplifier, you must secure the rear support brackline, the louder the amplifier will play and the more ets of the amplifier to the back of the rack. You could peak output power will be available for cleaner, punchuse a support rail or shelf across the back of the rack, or ier bass. angle brackets attached between the rear support rails and the rear rails of the rack. This is recommended for If you have more than one amplifier sharing an AC all components mounted in a rack that is going to be outlet, you should avoid turning them all on at the moved frequently. Rather, sequence them on, one at a time, to prevent popping the circuit breaker (due to in-rush current). MAINTENANCE Usually, your amplifier will not require regular maintenance for normal use. However, you can do several things to keep it in good operating and cosmetic condition. · Testing: Periodically test your system for proper performance. A simple test is to play a CD through it using well-defined, articulate, wide-range program material. Listen to ensure all drivers are working properly and for any evidence of distortion or other extraneous sounds. Cleaning: Use only a clean dry cloth to dust off and clean the surface. Turn off the power to the amplifier while you do this. THERMAL CONSIDERATIONS The power amplifier is fan cooled. Air is drawn through the rear panel vents, to cool down the amplifier heatsinks, and then expelled through the front panel vents. When installing, be sure to allow sufficient air space around the front and rear of the amplifier for adequate cooling for the heatsinks. Leave at least one rack space above and below, and at least 6 inches behind and in front of the chassis to allow proper ventilation. · Owner's Manual 11 FRS SERIES AMPLIFIERS Appendix A: Service Information If you think your Mackie product has a problem, please check out the following troubleshooting tips and do your best to confirm the problem. [. . . ] The return ground shipment is covered for those units deemed by us to be under warranty. Note: You must have a sales receipt from an authorized Mackie dealer for your unit to be considered for warranty repair. IMPORTANT: Make sure that the Service Request Number is plainly written on the shipping carton. LOUD Technologies reserves the right to inspect any products that may be the subject of any warranty claims before repair or replacement is carried out. [. . . ]
