Product Details

We are audio amplifier manufacturer and supplier. There are two options in circuits for the X audio amplifier. The first choice is CLASS H with 3 groups of voltage to drive the amplifier. The advantage of this kind of circuit is to make every penny for more power. But the restrictioin is, the efficiency of the amplifier will become lower than the second choice. Yes, for the second choice, you will have ONLY ONE voltage to drive the amplifier to save the energy for more power. However, for this kind of design, the amplifier will be required for some better devices to finish the convert. In this case, the cost will be higher than your first choice. Just choose what you are fond of, we are flexible to change and finish a good amplifier for your use.
