Ustars Audio R19 Digital Audio Board 32Bit PCM384KHz DSD512 Coaxial DOP128 For Raspberry Pi
Read Before Purchasing:
- Hands-on ability and basic knowledge are needed for product installation and using.
- Only fits users for Raspberry Pi and related player software Volumio and Moode.
Introduction:
1. Professional SPDIF digital processing solution, coaxial support output 384K/DOP128, better than common AK4118, WM8804 solutions
2. Local dual audio clock synchronization, avoid using PLL to generate clock and cause cold sound
3. Board for Raspberry Pi uses IIS to play music, and the listening feels smooth, real and natural
4. Use the general version for VOLUMIO, MoodeAudio. The official version for VOLUMIO can support 44.1-192KHZ DSD64 original code output. The official version for MoodeAudio can support 44.1-384KHZ DSD64-DSD128 original code output
5. There is no need to set output resampling, just turn off by default, truly original code lossless output
6. Adopting DS8921, a dedicated driver chip for coaxial, which is recognized as good sound
7. Use HDMI interface to output IIS signal, with MCLK output, you can set multiple output modes and MCLK clock frequency, which is convenient to connect to most high-end DAC decoders on the market
Specifications:
Digital output:
- Coaxial: PCM 44.1KHz-384KHz/24Bit; DSD DSD64/128 (DOP)
- Optical fiber: PCM 44.1KHz-192KHz/24Bit; DSD DSD64 (DOP)
- IIS: PCM 44.1KHz-384KHz/32Bit; DSD DSD64/128/256/512 (Native DSD)
Parameter Test Description:
For Raspberry Pi 4B (version 1.2) to install the optimized version for MoodeAudio640. The output setting is: Audiophonics ES9028/9038 DAC, measured when playing music files on the USB flash drive, there will be differences under other conditions, for example: for MoodeAudio7.01 can support PCM384KHz /DSD128.
Powered by:
The 5V power supply of the board is directly connected to the 40P interface of the board for Raspberry Pi. There are two ways to supply power as follows:
a. Directly use micro_usb to power the board for Raspberry Pi, and power the audio board from the 40P interface of the board for Raspberry Pi
b. Power is supplied from the DC socket input interface of the audio board, and the audio board supplies power to the board for Raspberry Pi through the 40P interface
Attention: Only one of the two power supply methods can be used at the same time, and the two cannot be used at the same time, otherwise it will cause damage to the board, the board for Raspberry Pi or the power supply.
Board Power Supply Interface Input Specifications:
- Power supply voltage: DC stabilized voltage +5V, voltage range: ±5%
- Power interface specifications: 5.5/2.1, inner positive, outer negative
- Suggested power supply current: ≥2000MA
- Single board working current: <100MA (board for Raspberry Pi not included)
- The pictures on the product introduction are for reference only and are subject to the actual product. As the raw materials supplied by the market may change, the product is subject to change without notice. Thank you for your understanding!
Compatible Main Boards For Raspberry Pi:
- For Raspberry Pi 2B
- For Raspberry Pi 3B
- For Raspberry Pi 3B+
- For Raspberry Pi 4B
Package Included:
- 1 x Set of Digital Audio Board
Note:
- Board for Raspberry Pi is not included.
- The optimized version for MoodeAudio640 is only available for Raspberry Pi 4B (version 1.2), Raspberry Pi 3B+ and Raspberry Pi 3B. Most of boards for Raspberry Pi 4B (version 1.4) or above versions currently on the market cannot be used for MoodeAudio640.
For MoodeAudio Settings:
The setting method uses a mobile phone connection. Take settings for MoodeAudio7.01 as an example. Other versions may have differences. The setting method for VOLUMIO is similar. Please handle the basic operations such as memory card flashing and setting up the network by yourself.
