L1387Portable4.4 DAC Headphone Amplifier 4.4mm Balanced Output with Data Cable to Connect Computer

L1387Portable4.4 DAC Headphone Amplifier 4.4mm Balanced Output with Data Cable to Connect Computer

Features:
- 4 classic TDA1387 decoding chips connected in parallel for output, and the sound reflects usual mellow style for Philips
- VIA's USB transmission solution realizes NOS mode to decoder chip, supporting up to 384KPCM transmission
- The NOS de-sampling method is used to further make the sound more natural
- Powered by 8.4V lithium battery, it completely eliminates the high-frequency interference caused by voltage boost and negative voltage reversal
- A lot of optimizations have been made to the USB interface digital transmission, decoding circuit, headphone amplifier circuit, independent decoupling, wiring, etc.
- Use a PCM software decoder up to 192-384K to decode DSD audio files
- Refer to the circuit of RA1 battery version. Four amplifier circuits are used to form a 4.4mm balanced output
