To reach the Max output, the input power also should be the MAX.<br><br> 2. The input power should be within the range, or it will be damaged.<br><br> 3. The different modes work under different conditions, so please check instruction before using it.<br><br> <br><br> Something New and impirtance about the Updated Version:<br><br> Q1.Why did we decide to design a "Fan" on the amplifier?<br><br> A1. During the programming of investigating regular customers of the amplifier, over two thirds of the customers leave the mssage that they need to put a additonal fan to cool the amplifier when it is working.They think sometimes, when a fan is not availabel, it will get much more business. Also, considering that the high degree of heat dissipation will affect the amp's working efficiency, our engineers decided to put a fan on the amplifier. It does greatly ease the problem.<br><br> Q2. Why chose such a " loud voice " fan to put on the amp.<br><br> A2. Dear friend, if it is that at the first, we got two kinds of the fans to consider ---- one is with lower noise and cost but just with lower rotate speed, while another one is with a louder noise and higher cost, but it works more perfectly and feectively with hiher rotate speed. So, we choose the later one, although the noise is louder but it does work well with the heat dissipation.<br><br>
