ES9038Q2M DAC Chip
Using the DAC chip ES9038Q2M from US ESS company, built-in Time Domain Jitter Eliminator,delivers a DNR of up to 129 dB and THD+N of -120dB.
DAC has built-in 7 PCM filters and 1 DSD filter, which are corresponding the follows:
1. The effect of the above filter is for reference only. It is subject to the practical hearing.
2.The main effect of DAC filter is to filter the useless cutter signal out of the voice frequency(above 20k), making the rear operation amplifier circuit processing audio is cleaner and more efficient. As a matter of fact, the smoothing cut-off frequency is away from the audio frequency, thus having litl influence on the sound. Sometimes, it can’ t be perceived obviously. It is almost the same before and after adjusting. If the difference can” t be distinguished, it can be ignored.
3. lt is generally believed that human ear can’ t hear the high frequency above 20khz. However, some people believe that the high frequency of 50k or even 150k will affect the tone quality. Therefore, we will set the corresponding adjustment to meet the needs of some users.
