2x15w stereo power amplifier circuits based TDA1521
It is small and compact stereo amplifier is powerful but can easily be used to replace your broken amplifier or new construction, or to make an active speaker, in all cases combined with a preamplifier. With remarkable features make it the true Hi-Fi amplifier.
Using only active component (the right and left channel) Philips TDA1521 monolithic integrated circuit, which contains a double line-end audio amplifier completely independent, each capable of providing from 10 to 12 W to the load 8 ohm or 15 W into 4 ohms (30 W music). Voltage gains of the amplifier is fixed at 30 dB.
