D50 Bluetooth 4.2 Hifi DAC Headphone Amplifier Dual ES9018K2M Decoding Chips For LDAC 64G U Disk

D50 Bluetooth 4.2 Hifi DAC Headphone Amplifier Dual ES9018K2M Decoding Chips For LDAC 64G U Disk

Features:
- 2pcs ES9018K2M decoding chips
- Support for Bluetooth 5.0 expansion APTX-HD protocol
- Volume: 18 x 12 x 4cm/7.1 x 4.7 x 1.6 inch
- Support U disk formats: wav, mp3, ape, flac, wma
- Support U disk up to 64G
- Support U disk up to 24B 48K master tape playing
- Coaxial, optical fiber inputs (coaxial, optical fiber both support 24B192K sampling rate input)
- Contains a pair of OPA2604 and a pair of OPA604
- Headphone hole with LO direct output function, which can drive 120Ω headphones. Wearing 64 ohms headset (the drive mentioned here is when the sound quality is relatively good. If you push it alone, it can be pushed to 600 ohms. But it does not mean that the sound quality will be better. Optional headphone amp module. It can drive 600 ohms earplugs. For 250 ohms headset.)

Advantages:
- Using zero-distortion digital volume adjustment technology to compensate for the exponential distortion of common analog potentiometers from low volume to large volume. Only after turning up the volume, there will be high, medium and low frequency balance.
- Hardware phase-locked loop matrix is added to transform the digital signal of glitch into a regular digital signal, which can effectively reduce jitter value. Make sound details more prominent, eliminate high-frequency burrs, and eliminate pops.
- Two decoding chips are used for left and right channels independently. Compared with one decoding chip, they have twice the thrust of a single decoding chip, in terms of left and right channel separation, resolution, and signal noise. Ratio, dynamics are better than 2 times the theoretical value of a single chip. However, due to loss, there will be a 1.6 times improvement effect.
- 5A adapter is enough to meet the D50 with only 200MA working current. This decoder uses 6 groups of low noise and high current power management chips.
- Each group of chips can support a maximum operating current of 2A. It is sufficient to cope with the current demand in large dynamic situations, and each group of power supplies providing power to different modules. Do not interfere with each other, the background is dark and quiet. Working for a long time, the machine does not heat up.
- Using 4pcs op amps to adjust sound, the first-level differential thrust is increased, and the second-level tuning timbre is solid and solid, without digital flavor, which enhances the sense of music and improves the sound quality. And with the plug-in design, players can easily replace with their favorite op amp.
- Use independent constant temperature active independent crystal oscillator to minimize Jitter value. Further improve music details and separation, reduce noise and glitches.
- Screen can display the name of songs currently playing on your U disk.
- 3 ways to choose U disk song mode, panel with a 4-way switch, remote control selection, APP selection song.
- APP can select songs for multiple folders, and similar songs can be grouped into one folder, making it more convenient to select songs.

Package Included:
- 1 x Set of DAC
