[. . . ] Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc. Will affect its performance and may even damage the unit. the unit can be mounted in 19-inch racks. Attach the unit using the 4 screw holes on the front panel. Be sure to use screws of the appropriate size. (screws not provided) Take care to minimize shocks and vibrations during transport. When installed in a booth or flight case, please make sure to have good ventilation to improve heat evacuation of the unit. To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance. CLEANING THE UNIT: Clean by wiping with a cloth slightly dipped with water. Do not use volatile liquids such as benzene or thinner which will damage the unit. Clean the ventilation holes regularly with a vacuum cleaner. VENTILLATION HOLES: during its operation the amplifier produces heat that needs to be dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore is it very important not to cover any of the ventilation openings as this may result in overheating. Clean the ventilation holes regularly with a vacuum cleaner. You can use these controls to set the maximum sound level of your setup: Turn both controls on the amplifier to the left. Put on some music on and make sure the VU meters on your mixer are at 0dB. (from time to time the red zone is lit) Set the Master output from your mixer to maximum. Open the Gain controls from the amplifier until the maximum desired sound level is reached. Make sure nobody can reach the Gain controls of the amplifier. You have just set the maximum level the DJ is able to produce. [. . . ] FAN & VENTILLATION HOLES: during its operation the amplifier produces heat that must be dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore is it very important not to cover any of the ventilation openings as this may result in overheating. XLR/JACK inputs: You can connect these balanced inputs to balanced and unbalanced line level audio sources: Balanced source: Use good quality XLR/XLR balanced audio cables. [. . . ]
