Double PCM1794A DAC Decoding DIY Suite Introduction:
The PCM1794 has a sampling rate of 24bit 192kHz, which has high analytical force, speed sensation, and transmissive, three-frequency balance, especially human voice, sweet, cost-effective.
2 PcM1794 parallel, dynamic range and signal-to-noise ratio have greatly improved, reaching 132dB, after parallel, output current is double, the sound density is enhanced, the entire sound is more balanced, the sound, the sound, the background is also cleaner.
A 1794 chip is only responsible for a channel, the independent line is really balanced, the two channels do not interfere with each other, the sound is brittle, clean and transparent.
Power supply is recommended to supply power supply, detail, speed, and slenderness, linear power supply ratio ZUI DC transfer DC power supply is better and stable, and the sound field opens positioning.

Parallel double 1794 chip
2 pieces of BB company top audio flagship store decoded PCM1794A, parallel dual core output sound quality exceeds AK4493, ES9038Q2M, ES9028QM, PCM5102, CS4398 and other terminal decoding chips,
The dynamic is high frequency extension, and the air feeling is well positioned.

True balance output
A 1794 chip is only responsible for one channel, the independent line is really balanced, and the two channels do not interfere.
The sound is crisp, clean and transparent, and the analytical force is good.

Convenient, playable
Can be transferred from yourself
Default 5532DD + 5534DD, DD represents double precision, It is conducive to the increase in the response speed of the system to audio.
Let the signal distortion are lower, more dynamic.
