Focus on extracting and purifying the essence of your music

Feel the essence of digital music, let the music fully restore the live effect and be in the scene!

Custom Built Motherboard for Audio

The Rhein Z1 provides a customized and dedicated motherboard for your audio usage. Low noise for high quality music playback, and shortest data path makes a smoother and purer data transmission possible. The Rhein Z1 consumes less power and introduces less noise on the power rails to ensure more stable USB and network signals. The independent USB-audio-dedicated-circuit effectively isolates the USB audio processing to generate less interference. As a result, data transmission is more stable, and jitter during data transmission is reduced.




Ultra Low CPU Power Consumption

The Intel mobile series CPU provides ultra low power consumption (as low as 6W), reducing electrical noise from the CPU and stabilizing the signal inside the Rhein Z1 and preventing it from affecting any nearby audio devices.

Fully Customized Power Board

A fully custom power board is capable of a 160W output, however the Rhein Z1 only requires 40W, and provides sufficient power to the motherboard and SSD to ensure stable data transmission.


High Quality Chassis made of Aerospace Industrial Grade Aluminum Alloy with CNC Processing

Its compact and ingenious industrial design makes the Rhein Z1 a form of art, and is patented in China. Its fan-less design makes no mechanical noise. 

Patented Structure Design

The groove structure design works to reduce signal interference, standardizing the line direction and placement. The design has obtained Chinese patent certification.

High Permeability EMI Absorber

To eliminate high frequency electrical noise from digital circuits, the Rhein Z1 uses specially a chosen EMI absorber at the inner side of bottom case to absorb EMI noise from internal digital circuit including the DRAM, CPU, etc.

Silent Angel Select High Quality Cable and Wires

To get a more stable signal and less electrical noise emission during signal and power transmission, the Rhein Z1 uses carefully chosen high quality cables and wires in its power button signal, power LED signal, SATA power and SATA signal.

 

Power LED and Power Button Signal

Teflon-coated ​silver plated wires are suitable for the connection of electrical equipment and instrument lines under high temperature conditions and high voltage up to 600V. It features resistance to high temperature, aging, acid and alkali, moisture, water, oil, corrosion,  and is flame retardant and other properties.

 

SATA Power Wires

​Take a look at the photo of the wires above. In the ordinary copper wire at upper side: The copper wire crystal is irregularly crystallized, and the conductivity is poor. As a result, it generates more electrical noise while power loading varies during system is accessing SSD.

​The Rhein Z1 uses OFC copper wire as SATA power wires: The copper wire crystal is evenly distributed by the high temperature, hot casting, continuous casting method, and the current conduction is good and introduces less electrical noise while power loading varies during system is accessing SSD.

 
Server Grade SATA Cable

The server grade SATA cable is optimized to ensure the stability of the signal transmission. The irregular distribution of the SATA cable in the foam layer generates an irregular telecommunications magnetic field, which affects the signal transmission quality. It also uses durable SATA connectors at both ends to ensure  the best connectivity quality.

The special designed exclusive audio SSD features fast access speed, low power consumption, good anti-noise, and stronger anti-interference. It effectively ensures the stability of the output signal, better output data stability, introduces totally different listening enjoyment and experience for you, and brings more fidelity to music.






Efficient VitOS Operating System

The Rhein Z1 features a VitOS operating system designed for music servers that focuses on streaming services. VitOS improves machine efficiency, performance stability and network latency issues.



VitOS: An operating system specially built for music server.

1. Dual Firmware: Prevent from being damaged while firmware upgrade.

2. Network accelator: Accelerated network processing

3. USB Audio Optimizer: Optimized USB Audio processing

4. Task Manager: High efficiency task management

5. Application Manager: Able to expand more and more application.

6. System Manager: Event-trigger design gets lowest system loading.

Mobile app for VitOS: VitOS Manager Features

1. Discover Rhein Z1 and adjust the network settings of Rhein Z1
2. Install and manage Roon Server in Rhein Z1.
3. Control the music importer, which imports music from the USB hard drive to the data disk in Rhein Z1 and view the music import details and result.
4. Update the firmware of Rhein Z1.

VitOS Music Server Performance Comparison

Test method: Play the same music track, captures network packets on Roon player and analyze the latency of response packets to and from Roon server. Then analyze the Roon server response packet latency and compare the result between different systems.

Lower latency implies better music server performance.
