LONTEN M7A JRC55320 ES9038Q2M I2S DSD Optical Coaxial Input Decoder DAC Headphone Output Audio amplifier Board customize

 

Voltage: DC 9-15V

Input support:

Coaxial: PCM44.1k ~ 192k 24bit / DOP DSD64

Fiber: PCM44.1k ~ 192k 24bit / DOP DSD64

   I2S / DSD: PCM44.1k ~ 384k 32bit / DSD64, DSD128, DSD256

   I2S / DSD pin definitions: PCM_BCLK-DSD_CLK, PCM_LRCK-DSD_L, PCM_DATA-DSD_R

The main selling point:

 

   ~: Perfect and seamless interface, PCM DSD switch without defect.

   ~: ES9038Q2M more perfect parameters, 129dB DNR -120dB THD + N

   ~: Easy to install

 

Because the ES9038's MCLK is a stand-alone clock of 100M, it is enough to simply enter DATA BCK LRCK. Sanding CD DVD old decoding effect is very good. Delicate and rounded, the extension is very good. 5532 op amp with the default, you can upgrade their own op amp, high-precision active crystal.

 

Audio input settings:

 

  J1 short , coaxial input

 

  J2 shorted, optical input

 

  J1 and J2 are not shorted, I2S input

 

Filter settings:

 

 J3, J4, J5, J6 not shorted, filter = apodizing fast roll-off filter

 

 J3 not shorted:

 

  J4 short, filter = brick wall filter

 

  J5 shorted, filter = corrected minimum phase fast roll-off filter

 

   J6 shorted, filter = minimum phase slow roll-off filter

 

 J3 short circuit:

 

  J4 shorted, filter = minimum phase fast roll-off filter

 

   J5 shorted, filter = linear phase slow roll-off filter

 

   J6 shorted, filter = linear phase fast roll-off filter

 

volume control:

 VOL: 1-2 short to mute, 2-3 short to the maximum volume

 Can be an external single potentiometer, Potentiometer rotary handle to the jumper direction, followed by the corresponding wiring, increasing the volume from left to right
