D3a Basic Version DAC Audio Decoder Dual PCM1794A Supporting Coaxial and Optical Input
D3a (Basic Version):
- Chip: Dual PCM1794A
- Bluetooth: None (with coaxial and optical input)
- USB: None (User can install USB card)
- Op amp: NE5532Px3
Material List:
- For Nichicon
- Dual PCM1794A
- Pluggable op amp
- For WIMA
- For Nover
Attention:
- Power adapter and antenna are not included.
- Remote control is included.
- Electronic components are subject to periodic changes and will be replaced with components of the same quality.
- The picture is for reference only, the electronic components will change without notice. Please refer to the actual product. Thank you for your understanding!
Features:
- Remote control functions: switch on/off, mute, switch input source
- PCM1794A chip: It has high sampling rate and resolution. Its sense of speed and transparency is very good, and the three-frequency sound is very commendable, especially the mellow and sweet vocals. This is a very cost-effective chip
- Screen display: Using a 1.2-inch IPS display, it can display the signal channel being input and the real-time sampling rate. Large viewing angle display allows users to master audio information from a distance
- Signal receiving: Adopt CT7302 receiver scheme PCM 32BIT/384KHZ, let PCM1794A support input DSD and DOP. The CT7302 is a lower jitter S/PDIF receiver than the AK4118. High sampling rate: advanced digital input processing chip CT7302, input channel with power-down memory, low jitter, high sampling rate
- MCU software control: The performance of PCM1794A is optimized by software control of single chip microcontroller solution. Power on/off through the panel buttons. The input signal is automatically recognized. Using broken sound elimination technology, it can solve the broken sound generated when the song is switched, fast forwarded, and the sampling rate is changed.
- Filter op amp: Adopt active LPF, and I/V conversion design. Compared with other passive resistance-capacitance structures, it is more conducive to improving the system's response speed to audio, making the signal distortion lower and the music dynamic more rapid and powerful
- 3pcs dual op amp: reserved IC seat, through simple plug and play, you can replace the op amp of different music styles
- High-quality power supply: Built-in true dual-source positive and negative voltage conversion design. Compared with other capacitor voltage divider structures, it is more conducive to improving the symmetry of positive and negative voltages, and making the PCM1794A decoding smoother
- Secondary voltage regulation: High-performance power purification circuit design reduces ripple interference caused by switching power supply, and provides clean power for DAC and LPF
- Support a variety of input sources and switching is more convenient
Specifications:
- Dimensions: 120 x 95 x 30mm (LxWxT)
- Weight: 283g
- External power supply: 12V DC (jack 5.5-2.1)
- Input Interface: Coaxial and Optical
- Output interface: RCA (output level 2Vrms)
- Sampling rate: 16-32Bit 44.1-384kHz
- Power consumption: 0.58W (standby <0.1W)
Package Included:
- 1 x Main unit
- 1 x Remote Control
Note:
- Battery for the remote control is not included.
