D5a Basic Version DAC Decoder ES9038Q2M DAC Supporting Coaxial Optical Input with Remote Control

D5a Basic Version DAC Decoder ES9038Q2M DAC Supporting Coaxial Optical Input with Remote Control

Features:
- Transparent and natural sound; full sound quality
- With remote control: power on/off, adjust volume, and switch input via the remote
- 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
- Multiple input: support optical and coaxial inputs. With volume adjustment, it can be used as a preamp
- 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
