Bluetooth 5.1 Receiver USB DAC Receiver ES9038Q2M QCC5125 for LDAC APTX HD (B5c Isolated Version)

Bluetooth 5.1 Receiver USB DAC Receiver ES9038Q2M QCC5125 for LDAC APTX HD (B5c Isolated Version)

Features:
- Bluetooth antenna: 2.5DB by default. You can also choose other antennas
- Rich details and plenty of dynamics
- Bluetooth receiver for LDAC and ES9038Q2M DAC
- Mobile phone bluetooth to speaker: Allows speakers without bluetooth to play wirelessly. Older amplifiers can also play richer music sources wirelessly
- Wireless input: Adopt QCC5125 Bluetooth 5.1 scheme which is newer than CSR8675. Supports multiple encoding types, such as for LDAC, aptx-Adaptive, aptX-HD and AAC; supports 24bit 96kHz audio CD-level sound quality; super cost-effective
- Good sound quality and no lag. Reduce the secondary loss of sound quality compression, accurately reproduce the full audio bandwidth, and achieve HIFI-level high fidelity
- ES9038Q2M decoding chip: adopt the latest ES9038Q2M decoding scheme, with 32BIT/384KHZ DAC patent structure for Hyperstream. It also has time-domain jitter removal technology and 129dB of dynamic range and -120dB of distortion. ES9038Q2M is a rare high-performance level DAC chip in the industry today, with transparent sound quality, high density and rich details
- Signal Direct: Turn off the volume control, maintain the maximum level output, reduce signal interference, and make the sound more realistic
- Single-chip software control: It adopts the single-chip microcontroller solution to optimize the performance of ES9038Q2M; it automatically recognizes the input signal. Software-controlled and optimized breakouts for song cuts, fast-forwards, and sample rate changes
- Filter op amp: Compared with other passive RC structures, the active LPF and I/V conversion design is more conducive to improving the system's response speed to audio, resulting in lower signal distortion and better music dynamics
- 3 Op amp: With reserved IC socket, users can replace them with new op amps with different music styles by simply plugging and unplugging
- Output protection: Original HF relay is adopted, which is delayed to close when starting up, and immediately cuts off the power supply when shutting down. Avoid the popping sound of startup and shutdown, thus protecting speakers from causing damage
- High-quality power supply: Compared with other capacitor voltage divider structures, the built-in positive and negative voltage conversion design is more conducive to improving the symmetry of positive and negative voltages, thereby making the Bluetooth signal (for LDAC) more stable, and ES9038Q2M decoding smoother
- Secondary voltage regulation: The high-performance power purification circuit design reduces the ripple interference caused by the switching power supply and provides clean power for the DAC and LPF
