New Linear Power Architecture
Partnering once again with Dr. Sean Jacobs, a new power supply architecture was designed exclusively for the Statement. The power supply is distributed between two enclosures, with one enclosure containing the AC/DC conversion stage and the other containing the regulation stage together with the server components.
The advantage is clear: regulated “clean” power traverses a very short path, soldered point to point, with the least impedance and exposure to EMI. This is superior in efficiency compared to a traditional architecture where a separate power supply is used – regulated “clean” power needs to go through more obstacles of internal cabling, output connectors, cable, input connectors and more internal cable before it reaches its destination.
8 Independent Linear PSU Rails
Each critical component of the server receives its own dedicated power supply from one of the 8 independent power rails, further preventing component cross-contamination. Of particular note is the use of a dedicated power supply for each of the Ethernet and USB high-precision OCXO clocks, ensuring these clocks work at their best.
The motherboard has been fully EMI-optimised to our own exclusive design by, removing any unnecessary, noise-generating components capable of compromising audio. A fully-customised BIOS ensures the hardware works at its lowest noise without impairing performance. Further EMI treatment is then applied to the motherboard so that EMI is absorbed rather than reflected to other components.
Custom-designed Ethernet and USB Re-clocker
Not fully satisfied with existing USB and Ethernet re-clocking designs, Innuos designed in-house their own boards for this purpose.
At the heart of the design are 3 principles: The use of very high-precision OCXO clocks for timing the signals, extreme care in powering important components preventing cross-contamination, and extremely short paths between components.
While apthe use of OCXO clocks is not new, the way they are powered and the layout of the board has proven to be extremely important for their performance. As an example, dozens of USB controllers were analysed in terms of how they were powered and clocked so that they allowed this control to be done externally. The USB Controller is regulated by no less than 3 ultra-low noise regulators, one per independent voltage.
Keeping the clock very close to the controllers, via a dedicated track on the board itself, helps to avoid the losses in signal quality that come with the use of external clock units.
10mm CNC-machined Aluminium Chassis
Housed in a casing of 10mm-thick CNC-machined aluminium, the Statement is not just a pretty face. The thick metal enclosure helps to isolate external EMI, and its weight helps dampen harmful vibration into the system. By using a double-enclosure design, it also helps to contain the vibration effects of the massive 540VA toroidal transformer at its heart.
