在唱片领域中,由乙烯基塑料制成的慢转(45及33(1/3)转/分)密纹唱片具有优异的电声性能:频率范围宽于30～12000赫,总谐波失真小于2%(录音频率1000赫、录昔速度7厘米/秒),动态范围高达45～50分贝以上.可见,密纹唱片能高保真地重现各种语声和乐声的全部频带,其放音效果可与调频广播相媲美.在本文中,就作为高保真度放音基础的唱片录音和放音特性进行讨论.
In the field of record, slow-rotating (45 and 33 (1/3) rpm) vinyl discs made of vinyl have excellent electroacoustic performance over a frequency range of 30 to 12,000 Hz, total harmonic distortion Less than 2% (recording frequency of 1000 Hz, recording speed of 7 cm / sec), the dynamic range of up to 45 to 50 dB above, visible music records can reproduce all the high-fidelity voice and sound all the frequency band, its The playback is comparable to FM radio, and in this article we discuss recording and playback of recordings that are the basis for high fidelity playback.
