在我国,高档套装音响器材还不可能普及。所以,自己动手制作音响设备,已成为工薪阶层发烧的一种途径。如何以最低的成本组装出高质量的音响设备,是每一位焊机派发烧友的追求。在音响系统中,较为简洁的设备结构是由调谐器、CD唱机、功率放大器、音箱组成。调谐器播放的节目丰富,架设一副好的天线,在城市中能收到许多调频立体声节目,而且播放的大都是CD唱片节目。一台较好的调谐器的信噪比大于70dB,频响20Hz～17kHz,这是普
In our country, it is impossible to popularize high-grade set audio equipment. So, making your own audio equipment has become a way for working-class fever. How to assemble a high-quality audio equipment with the lowest cost is the pursuit of every fan-sent fancier. In the audio system, a relatively simple device structure is composed of tuners, CD players, power amplifiers, speakers. Tuner broadcast programs rich, set up a good antenna, in the city can receive many FM stereo programs, and most of the play CD recordings. A better tuner SNR greater than 70dB, frequency response 20Hz ~ 17kHz, this is Pu
