4Make sure that the amplifier is turned down, before turning the power on or off. So you can avoidsupersonic frequencies, which could damage your speakers.Don't put your equipment next to TV, radio, etc., because of interference or distortion.If you connect other parts of the system, be careful of ground loops.The best way to avoid ground loops is connecting the electrical system ground to one centralpoint ("star" system). In this case the mixer can act as a central point.Before changing the ground, always turn off your amplifier.Please read this manual carefully and keep it for future reference. Remember that the amplifierhas a better value on the market, if you save the carton and all packing materials.Always operate the unit with the AC ground wire connected to the electrical system ground.Connecting amplifier outputs to oscilloscopes or other test equipment, while the amplifier is inbridged mode, may damage both the amplifier and test equipment.Do not drive the inputs with a signal level bigger, than required to drive the equipment to fulloutput.In system setup, the amplifier's output power must be 50%-100% more than the loadedloudspeakers rated power.Please turn off the power switch, when changing the power cord or signal cable, or select theinput mode switch.In typical use, please set the volume at 0dB position.Sometimes, when you want to send one signal to more than one amplifier, you should use a signaldistributor.If your Dap Audio device fails to work properly, discontinue use immediately.
