带速、抖晃率、信噪比、失真度和频响是盒式录音机的五个主要技术参数.前两个参数由机芯决定,而后三个参数则取决于电路.要想提高这三个参数中的两个还比较容易,但要同时将它们提到较高水平却是困难的.若放宽对频响的要求,可以将偏磁电流调大些,这样失真度就可降到2%以下,同时可录磁平也可高些,即信噪比也得到改善.若放宽对失真度的要求,
Band speed, dither rate, signal-to-noise ratio, distortion and frequency response are the five main technical parameters of the cassette recorder. The first two parameters are determined by the movement and the last three parameters are circuit dependent. Two of the parameters are still relatively easy, but at the same time it is difficult to mention them to a higher level. If you want to relax the frequency response, you can set the bias current slightly higher so that the distortion can be reduced to 2 % Below, at the same time recordable level can be higher, that is, the signal to noise ratio has also been improved.If the relaxation of the degree of distortion requirements,
