K4003 - 2 x 30w power amplifier

Description

This small amplifier uses the TDA1521 integrated circuit, providing a maximum of 2 x 15 W rms (4 Ohms) or 2 x 10 W rms (8 Ohms). This system is fully thermally and short-circuit protected. The system does not require a rectifier and a smoothing capacitor because it can be directly supplied with alternating voltage.
