D5b Standard Version Bluetooth DAC USB DAC Dual ES9038Q2M Bluetooth 5.1 Receiver for LDAC APTX

D5b Standard Version Bluetooth DAC USB DAC Dual ES9038Q2M Bluetooth 5.1 Receiver for LDAC APTX

Features:
- Transparent and natural sound; full sound quality
- 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
- 1.3" screen display: OLED high-definition wide-angle display can display the input signal channel, 255-section column volume bar and real-time display sample rate and digital filter mode
- PCM: When PCM is input, there are 7 kinds of digital filter modes that can be adjusted, which are displayed in real time in the upper right corner
- DSD: When DSD is input, the sampling rate of the audio source is displayed in real time
- DOP: Support optical fiber, coaxial DOP input, optical fiber 64, coaxial 128
- Signal Direct: Turn off the volume control, maintain the maximum level output, reduce signal interference, and make the sound more realistic
- With dual ES9038Q2M, it has lower signal-to-noise ratio and harmonic distortion. The sound quality is purer, the level of detail and the sense of air are also improved
- MCU software control: It adopts the single-chip microcontroller solution to optimize the performance of ES9038Q2M. Software-controlled and optimized breakouts for song cuts, fast-forwards, and sample rate changes. 7 adjustable digital filter modes; automatic identification Input sample rate noise cancellation technology
- Output protection: Japanese relay is adopted, it will be closed with a delay when it is turned on; it will cut off the output immediately when it is turned off. Avoid the popping sound of startup and shutdown, thus protecting speakers from causing damage
- Filter op amp: Compared with other passive RC structures, its 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
- With remote control: power on/off, adjust volume, and switch input via the remote. It enables wireless playing from speakers without Bluetooth. Old-fashioned power amplifiers can also get rid of the shackles of cables and make digital music resources richer
- It uses the QCC5125 Bluetooth 5.0 scheme that is newer than the 8675. For LDAC, aptx-Adaptive, aptX-HD, and AAC. Support 32bit 384kHz audio CD-level sound quality; super cost-effective
- Multiple input: support USB, Bluetooth, optical fiber, coaxial input. With volume adjustment, it can be used as a preamp. Good sound quality and no delay. Reduce the secondary loss of sound quality compression, accurately reproduce the full audio bandwidth, HIFI-level high fidelity
- Onboard USB TYPE C input supports 48KHz 16bit. At the same time, it reserves a plug-in interface to upgrade the USB digital interface. All systems are driver-free; plug and play, convenient and flexible
