L1387DAC USB/BT Bluetooth Decoder Headphone Amplifier 4.4 Balanced Output Support for APTX/LDAC Protocols

Features:
- Using classic 8pcs TDA1387 HiFi decoding chip parallel output, the sound is warm and durable, very close to TDA1541.
- Adopting the latest Bluetooth chip for Qualcomm, it supports for aptX Adaptive and LDAC protocol 24bit 96k.
- Provides USB input and still supports 24bit 96k lossless bit-rate for both computers and mobile phones to connect via OTG.
- The transformer outputs dual 15V and single 6V to separately supply power to the headphone amplifier and digital circuit.
- Using classic two TPA6120 headphone amplifier chips in parallel to achieve balanced 4.4 and single-ended 6.5 headphone outputs.
- Provide a comprehensive headphone protection circuit, including startup delay, pre shutdown cut-off, and DC output detection.
