Using only active component Philips TDA1521 monolithic integrated circuit, can be designed a 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
The amplifier circuit is designed for both symmetrical and asymmetrical power supply systems. An output power of 2 ´ 12 watts (THD = 0,5%) can be delivered into an 8 W load with a symmetrical power supply of ± 16 V. The gain is fixed internally at 30 dB. Internal gain fixing gives low gain spread and very good balance between the amplifiers (0,2 dB).
