Referentni sustav nula kelvina

Postoje, broadly, two approaches to building a reference audio sustav. The first is incremental: you upgrade one komponenta at a time, each upgrade revealing a new weakest link, each revelation demanding another upgrade, until you have spent more on your sustav than you originally intended and still suspect that something, somewhere, is holding it back. The second approach is the Zero Kelvin Reference Sustav. You eliminisati every weakness istovremeno by eliminating the physical mehanizam that causes weakness: electrical otpor.

The Zero Kelvin Reference Sustav is a complete superprovodljivi signalni lanac. Four SC Power Cords isporučiti AC power from the wall to your izvor, DAC, predpojačalo, and pojačalo with zero otpor. One SC Word Clock Kabel distributes your master clock signal with zero jitter contribution. One SC Digitalni Kabel carries your digitalni audio stream with zero attenuation and cryo-locked impedansa. Two SC Interconnects transport the analogni signal from DAC to preamp and from preamp to pojačalo with zero šum. One pair of SC Zvučnik Kabeli isporučuje the pojačalo's full output to your loudspeakers with zero power loss and infinite damping factor. From the moment electricity enters your sustav to the moment it moves your zvučnik cones, the otpor is zero. Not low. Not negligible. Zero.

The infrastructure that makes this possible is the central LN2 reservoir: a 500-liter vakuumski izoliran stainless čelik vessel that feeds tekući dušik to all kabel runs kroz a 12-port distribution manifold. Each port is individually valved, allowing any kabel to be isolated for maintenance bez warming the rest of the sustav. A 24-sensor monitoring array tracks temperatura at each kabel's cryostat, pritisak in the reservoir and distribution lines, ambijentalni oxygen concentration in the prostorija za slušanje, and LN2 flow rate kroz each manifold port. The data is displayed on a touchscreen HMI mounted at the reservoir and mirrored to a web interface accessible via Ethernet, so you can monitor your sustav's kriogeni status from anywhere. If ambijentalni oxygen drops ispod 19.5% — indicating a significant LN2 leak — the sustav sounds an alarm and, if connected to a building management sustav, triggers emergency ventilation.

The first year of tekući dušik is included with the sustav. Based on an ambijentalni temperatura of 22°C and the aggregate termički leak rate of all included kabel runs, the estimated annual consumption is približno 5,840 liters. This figure will vary with your room temperatura, kabel routing, and how often the manifold ports are cycled. Naknadni years' LN2 is available kroz our annual subscription program or kroz your own industrial gas supplier — tekući dušik is a commodity product available worldwide. The sustav weighs over one tonne when filled. A structural floor assessment nije optional; to je mandatory, and to je included with the purchase cijena because we take seriously the possibility that your prostorija za slušanje floor nije bio konstruisan for a kriogeni instalacija.

The sustav tagline — "Zero-Point was still iznad zero" — nije a slight protiv our flagship bakar kabeli. The Zero-Point range predstavlja the absolute pinnacle of what is achievable with resistive provodnici. But a resistive provodnik, by definition, has otpor. The Zero Kelvin Reference Sustav is what comes nakon you accept that zero-point was never actually zero.
