Independently developed Gigabit Switching Hub 4 ports, USB 1+2 ports
W SmartHub 3.0 is fundamentally different from an audio hub made by processing only the power supply and chassis of a general hub. It is a product designed by Waversa's own technology, from motherboard design to noise removal by ultra-low impedance lithium-ion battery power supply, high-precision audio grade clock, self-developed chip, and network management.
Ultra-low noise design
1. 4 Bank, 4 x 18650 Li-ion battery realizes NOISE FREE The biggest noise source of a regular switching hub is a low-cost SMPS power adapter. W SmartHub's internal power is 100% battery operated. The lithium-ion battery not only suppresses its own noise generation with its excellent power supply capability, ultra-low impedance, and ultra-low noise, but also removes noise coming through the network cable, resulting in excellent sound quality.
2. Minimized jitter by adopting audio grade high-precision clock
Most of the common hubs employ low-cost crystal oscillator clocks. Clocks are divided into crystal oscillators, crystal oscillators, MEMS, OCXOs, etc. Naturally, the further back you go, the more sophisticated and expensive it becomes. As we all know, clocks are very important in digital audio. The WSmartHub 3.0 is designed to provide excellent performance by minimizing jitter generation by adopting a high-precision OCXO clock (WSmarthub 2.0 MEMS clock), which is used only in high-end DACs
The crystal oscillator method applies electricity to a crystal to generate a clock using the vibrating property. High-speed operation is impossible, the change is large according to temperature, and the clock itself vibrates. The OCXO clock employed in WSmartHub 3.0 utilizes the phenomenon that the semiconductor vibrates due to the generation of an electromagnetic signal, and operates much more precisely, has less displacement due to temperature, and almost no self-oscillation.
3. Realization of vibration, heat dissipation, and shielding through aluminum uni-body chassis. Aluminum uni-body has a higher manufacturing cost than anything else. The WSmartHub 3.0 uses a whole aluminum unibody cutting case, which is precisely manufactured as a Waversa product. The advantage of an aluminum unibody is that it has excellent effects in low vibration, heat dissipation and shielding.
4. Minimize all areas that generate noise, such as not using LED indicators. A typical hub has an LED for each port to show data traffic status. But from an audio point of view, this is also noise. The WSmartHub did not use any LED indicators considering this part. It is designed with the smallest details in mind for sound quality.
Modern Ethernet switches and Renderers
You can set speed adjustment and traffic control for each Ethernet port, and you can turn off ports that are not in use, significantly reducing battery usage and blocking noise transmitted to adjacent ports in advance. You can set the Ethernet port through WRemote
Display to check all status
In the previous version, you could only check the voltage of the battery, but from 3.0, you can also check the status of the Ethernet port, so you can intuitively check whether the port is communicating normally or not in use through the icon, so you can check the Ethernet port and battery voltage at a glance.
Changed battery operation
• Adoption of 18650 lithium-ion battery
• Extended Li-ion Battery Efficiency and Lifespan with 4 Bank Expansion
• Block the source of noise by changing the battery switching part from a relay to a MOSFET In the two-bank method, four batteries were required as one bank per two batteries was used. When one bank is in operation, two batteries are used, reducing the lifespan of the batteries and increasing the replacement cycle. This time, with the upgrade to 3.0, it was changed to a 4-bank method and consisted of one bank per battery. This allows only two batteries to function normally
Application of an OCXO clock
• The highest-grade OCXO clock is applied for better performance.
New Powersupply redesign
• WLPS filter part technology applied
• Switch to linear power when all batteries are discharged Power supply: External SMPS When the battery is discharged: Inoperable Power supply: WLPS power supply When the battery is discharged: Switch to the linear power supply / Battery discharge notification
Provides various information and the latest Ethernet switch (Managed)
• Front display information window of various information
• Modern Ethernet Switch (Managerd
• Speed control by port, On/Off, Traffic Control Smarthub 3.0 is larger than the existing Smarthub. It is larger in size and heavier due to internal design changes and adoption of 4Bank 18650 Li-ion batteries.
