To prevent fire or shock hazard, do not expose this appliance to rain or moisture. 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 or may even cause damages. [. . . ] In the event of serious operating problems, stop using the appliance and contact your dealer immediately. Due to safety reasons it is prohibited to make unauthorized modifications to the unit. INSTALLATION GUIDELINES: Install the unit in a well-ventilated location where it will not be exposed to high temperatures or humidity. Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc. (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. 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. 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. (in some cases the DJ is not ) Note: In Mono and Bridge mode, only the gain control of the left channel is used to adjust the input sensitivity. In the description of the unit you will find more information on how to connect the amplifier. Switch (12) on the rear panel is used to choose one of these 3 possible modes: STEREO MODE: Both LEDs are lit. Basically this is identical to stereo mode but the inputs of both channels are linked so the output will be mono. In this case you only need to use the input of the left channel to drive both output channels. [. . . ] 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. [. . . ]
