单声道声频设备主要调测幅频特性,总谐波失真,信号噪声比,录音机抖晃等四大指标。而立体声声频设备除四大电声指标外还有几个独特的电声指标,就是通道间的通道平衡、相位差和串音等。立体声录音机的录音工作磁平与单声道录音机也不同,频响调测也有差别,随着技术发展和测量手段的完善,在调测声频设备时还增加了一个指标,就是方波■应的测量。
The main parameters of mono audio equipment are amplitude and frequency characteristics, total harmonic distortion, signal-to-noise ratio, audio jitter and other four major indicators. The stereo audio equipment in addition to the four major electro-acoustic indicators there are several unique electro-acoustic indicators, is the channel between the channel balance, phase difference and crosstalk. Stereo Recorder recording magnetic level and Mono Recorder is also different, frequency response measurement are also different, with the development of technology and measurement tools to improve, in the commissioning of audio equipment also added an indicator that is the square wave should be measuring.
