飞利浦公司过去推出的高保真音响功放集成电路TDA1521及TDA1514A,可谓发烧友们业余制作功放之首选。然而与之一脉相承的另外一枚飞利浦集成电路TDA1524A却知之者甚少。此集成电路是双声道音调控制电路,采用直流电平控制双声道音量、平衡、高音、低音并有响度开关。实践证明,将其用于TDA1521或者TDA1514A之前,不仅对音乐的控制有出色的表现,同时也是实用发烧、一举成功的上好组合。那些手中仅有VCD或者CD机而又想亲自动手制作一台物美价廉的实用性功放的工薪族朋友们不仿一试。
Philips introduced in the past high-fidelity audio amplifier integrated circuits TDA1521 and TDA1514A, can be described as the first choice for enthusiasts amateur production amplifier. However, with one pulse of the other Philips TDA1524A Philips has little to know. This integrated circuit is a two-channel pitch control circuit that uses a DC level to control two-channel volume, balance, treble, bass and loudness switches. Practice has proved that before its use for TDA1521 or TDA1514A, not only excellent performance of the music control, but also practical fever, a good success in one fell swoop. Those in the hands of only VCD or CD player and want to personally create a practical inexpensive power amplifier workers do not give it a try.
