相对测量:<>用导线直接把 maya 的输入、输出口连起来,运行RightMark Audio Analyzer,得到 maya 本身性能数据,国外网站测量 maya44 数据公布如下(maya44为maya的升级版,音频指标基本相同,maya 的信噪比、THD、IMD等各项指标确实是很优秀的):<>Tested chain: Maya44 Line Out 1 - Line In 1
Operating mode: 16bit 44100 Hz <>Frequency response (40 Hz - 15 kHz), dB -0.07, +0.00 Excellent
Noise level, dB (A) -90.3 Very good
Dynamic range, dB (A) 87.7 Good
THD, % 0.008 Very good
Intermodulation distortions, % 0.014 Very good
Crosstalk, dB -87.8 Excellent <>Tested chain: Maya44 Line Out 2 - Line In 2
Operating mode: 16bit 44100 Hz <>Frequency response (40 Hz - 15 kHz), dB -0.06, +0.00 Excellent
Noise level, dB (A) -92.0 Very good
Dynamic range, dB (A) 89.6 Good
THD, % 0.002 Excellent
Intermodulation distortions, % 0.008 Very good
Crosstalk, dB -86.1 Excellent <>这个数据和arnoldcen测量的数据比较一下,或者说减一下,基本就是放大器的真实数据了。arnoldcen有空也可以测量一下,这样数据就更清楚了。<>
