Core equipped with Raspberry Pi Compute Module 4 (CM4)
The RPIpro bridge adopts the Raspberry Pi 4th generation computing core module CM4, which outputs directly through native USB,
Avoiding signal loss and interference caused by PCIe conversion of Raspberry Pi 4B.
Multiple commonly used software supporting Raspberry Pi 4B system can run on RPIpro, such as Volumio,
Ropieee,Moode，PiCorePlayer。 Before RPI Pro leaves the factory, we will install Ropieee
System, Ropieee not only has good sound quality, but also is easy to use. Even if you don't have the built-in Ropieee
There is a Roon core, and you can also directly cast music onto your phone for decoding, which is much better than using Bluetooth
The effect is much better.
Built in high-precision clock system
Equipped with a high-precision and low phase noise SC CUT OCXO constant temperature crystal oscillator (PN: -1000dBc/1Hz)
Typ. serves as the reference clock benchmark for the entire machine
Using SkyWorks' high-performance PLL phase-locked loop chip to generate multiple high-precision synchronous clock signals
Number, provide for the main computing unit (CM4), network control chip, and USB port processing chip respectively
The clock signal enables multiple modules within the entire machine to achieve clock synchronization.
·Equipped with a 1OMHz BNC external clock input, it can connect to higher-level reference clocks and automatically switch,
Meet the ultimate upgrade needs.
USB native output with isolation design
The USB 2.0 port is native to the CM4 core CPU and has not undergone any other conversion processing, significantly reducing signal loss and interference. At the same time, a 3165 high-speed isolation chip and power module have been added to the output end of the USB port, further improving the quality of this USB Audio port. Therefore, by directly transmitting digital audio to the DAC decoder through this USB Audio port, stable and accurate playback of high-resolution PCM and DSD files can be ensured, showcasing studio level delicate details and dynamic performance. Whether connected to high-end decoders, streaming media players, or HiFi systems, it can provide a high fidelity auditory experience with "zero compression" and "zero compromise".
Built in high-performance network controller
Simultaneously providing dual ports of RJ45 and SFP, making it convenient for users to cooperate with fiber optic modules and cables, easily achieving optical and electrical isolation of the network, significantly reducing network interference noise, and improving network signal transmission quality.
Carefully designed DC power supply
The whole machine adopts a 3OVA arrowroot ring transformer as the power core, and is equipped with multiple EMI filters.
·Using high-speed rectifier devices and multiple high-capacity electrolytic capacitors, a high-speed matrix filtering multi-channel is formed
·Adopting three independent high-performance DC conversion power supply circuits to meet the high-speed and dynamic requirements of digital circuits,
It can also provide low noise at the uV level.
