Introduction to the dual PCM1794A DAC decoding DIY kit:

The pcm1794 has a sampling rate of 24bit 192Khz, high resolution, speed, transparency, and triple frequency balance, especially with a rounded, sweet, and cost-effective voice.

Two PCMs 1794 are connected in parallel, greatly improving the dynamic range and signal-to-noise ratio to 132dB. After being connected in parallel, the output current is doubled, the sound density is enhanced, and the entire sound is more balanced, durable, and the background appears cleaner.

A 1794 chip is only responsible for one channel, with a truly balanced independent line, and the two channels do not interfere with each other. The sound is crisp, delicate, and clean and transparent.

It is recommended to use a linear power supply for power supply, with improved details, speed, and fineness. Linear power supply is better and more stable than Zui's good DC to DC power supply, with open sound fields and accurate positioning.

Parallel enhanced dual 1794 chips

Two top audio flagship store decoders from BB Company, PCM1794A, with parallel dual core output sound quality effects exceeding terminal decoders such as AK4493, ES9038Q2M, ES9028QM, PCM5102, CS4398,

Dynamic, high frequency extension, excellent air sense and sound field positioning.

------------------------------------------------------------------------------

True balanced output

A 1794 chip is responsible for only one channel, and the independent lines are truly balanced. The two channels do not interfere with each other,

The sound is crisp and warm, clean and transparent, with good analytical power.

---------------------------------------------------------------------------------------------------------------------------------------------

Convenient and highly playable

Self changeable operational amplifier tuning

The default is 5532dd+5534dd, where DD represents dual precision, which is beneficial for improving the system's response speed to audio,

Lower signal distortion and better dynamics.
