The LA4708 amplifier has two bridge outputs, which gives it a higher efficiency and allows you to develop an output power of 20 watts per channel. The microcircuit is a full-fledged amplifier. But for its correct operation, you need a harness from certain passive radio elements (resistors, capacitors, diodes) according to the circuit recommended by the manufacturer. Case Type SIP 18H. The advantage of this type of case is the convenience of mounting the microcircuit to the heat sink (radiator).
