用Alesis io26做录音
苹果音量50％，HD535听起来比较大音量，输出电平低了很多，DAW提升20dB，同时Alesis做了+14dB增益，成绩比较差了

Testing device	MacBook Pro 13' 374 and Alesis io26
Sampling mode	24-bit, 96 kHz
Interface
Testing chain	MacBook Pro out 50, Alesis line in 1-2 +14dB +20dB
RMAA Version	6.2.3
20 Hz - 20 kHz filter	ON
Normalize amplitude	ON
Level change	0.0 dB / 0.1 dB
Mono mode	OFF
Calibration singal, Hz	1000
Polarity	inverted/inverted

Summary

Frequency response (from 40 Hz to 15 kHz), dB	+0.10, -0.81	Good
Noise level, dB (A)	-77.9	Average
Dynamic range, dB (A)	78.1	Average
THD, %	0.0080	Very good
THD + Noise, dB (A)	-71.9	Average
IMD + Noise, %	0.062	Good
Stereo crosstalk, dB	-75.0	Very good
IMD at 10 kHz, %	0.029	Good
General performance		Good

音量100％时 电平高了一些 成绩也提高了
