Decoder features:

1. Adopt the current USB scheme

XMOS asynchronous xu208 chip makes the sound of computer reach a new level (the sound is more durable and lasting)

2. With AKM high performance, low distortion ak4490 chip directly

Decode PCM 384k audio signal, enjoy master band audio, and support direct decoding of dsd64, dsd128 and dsd256.

3. On board coaxial output, supporting 44.1k-192k sampling rate and dop64

4. The earphone chip is the hifi class earphone max9722 of Meixin

Small distortion, large output current and strong driving force. It only needs USB power supply. The actual effect is better than that of tda1308 and tda1308

TPA152 is more dynamic, which may be related to the chip design,

Because this chip does not need output capacitance, it is better for low frequency (generally, ear Amplifiers need output capacitance). The distortion of this chip is as low as

0.003%

5. Play the sample rate indication, and the playback status is clear at a glance (44.1k-384k, 10 indicators for DSD and PCM)

6. Gold Plated interface design, smaller contact internal resistance and higher temperature

7. Multistage precision ultra-low ripple voltage stabilizing chip,

Plus fever level components (Panasonic gold filter, Panasonic patch electrolysis,

Italian AV film capacitor (Elna output coupling capacitor) is the guarantee of good sound.

8. It can be powered by USB,

It can also be powered externally (it must be a 5V, dc3.5mm socket with a current greater than 500mA)

9. Overall dimension: 71 * 100mm (excluding protruding part)

10. Output audio signal 2.0V RMS, signal-to-noise ratio 112dB, distortion 0.001%

11. The default operational amplifier is ti's three in-line ne5532
