Mini USB DAC Headphone Amplifier HIFI DAC AK4490 Assembled Support DSD256 For XMOS DOP Output

Mini USB DAC Headphone Amplifier HIFI DAC AK4490 Assembled Support DSD256 For XMOS DOP Output

Attention:
- USB port does not support the insertion of U disks and hard disks, and can only be connected to devices for Android such as computers or mobile phones and set-top boxes! An optional kit is required to connect to mobile phone for iPhone. Hard solution.
- During DSD playing, the volume of all audio output ports is not adjustable (including headphone port).
- During DSD playing, when you play next song, pause, or fast forward, there will be a slight impact sound, which is normal. PCM playback will not have this problem. Please make sure that you don't mind before purchasing.
- USB cable is not included.

Features:
- Using trendy USB solution, asynchronous XU208 chip for XMOS, let the sound of computer reach a new level (Sound is more audible and has a charm).
- With high-performance, low-distortion AK4490 chip, it can directly decode PCM 384K audio signals, enjoy master audio, and support DSD64, DSD128, DSD256 direct decoding.
- On-board coaxial output, support 44.1K-192K sampling rate, support DOP64.
- American HIFI-grade amp MAX9722 is the amp chip, which features low distortion, large output current, and strong driving force. It is powered via USB power supply for better effect. The actual effect is better than the dynamics of TDA1308 and TPA152, because this chip does not require an output capacitor, which is better for low frequencies (generally amps require output capacitors). Chip distortion is as low as 0.003%.
- Playing sampling rate indicator. Playing status is clear at a glance (44.1K-384K, DSD, PCM, a total of 10 indicators).
- Gold-plated interface design, contact internal resistance is smaller.
- Multi-level precision ultra-low ripple voltage regulator chip, plus HiFi-level components (SMD electrolysis for Panasonic, Italian film capacitor, output coupling capacitor for ELNA), is a guarantee of good sound.
- Can be powered by USB or external power supply (must be 5V, DC3.5mm socket, current is greater than 500MA).
- Dimensions: 71*100mm (excluding the size of protruding parts).
- Output audio signal 2.0V RMS, SNR 112db, distortion 0.001%.
- OP Amp supports plug-in replacement and upgrade, with JRC4580*1 by default.
