The Atlas Ascent Ultra 75 Ohm SP-DIF digital cable is a superb cable which gives a considerable insight into the state-of-the-art performance of our ‘high-end’ Mavros interconnect at a very reasonable price. Ascent was designed to be technically and sonically superior to competing digital cables currently available at similar prices. Designed to maintain a true 75 Ohm impedance. The central conductor is made from OCC copper which is insulated by an extremely low-loss PEF (Foamed Polyethylene) dielectric. The tightly woven wire mesh together with an aluminium outer foil provides 100% rejection of RFI (Radio Frequency Interference) ensuring the music signal is free from any external noise. The cable is covered by a soft PVC sleeve and finished in a grey woven fabric. The Ascent digital cable is terminated with our cold-weld connected wideband Ultra RCA plugs. The result is a smooth, uninterrupted signal path which behaves as one continuous entity, with minimal degradation of the signal compared to soldered connections. This is particularly important in a digital cable, connectors which compress the cable can actually alter the cable’s impedance, which drops below the 75 Ohm specification, typically by up to 50%, reducing accuracy of the signal transfer. The Ascent digital cable can be supplied with BNC plugs as well as RCA plugs.
- The Ultra is a wide-band, OCC copper, constant impedance, self-cleaning, solder-free construction RCA plug.
- OCC (Ohno Continuous Casting) process was developed by Professor Ohno, from the Chiba Institute of Technology, to manufacture a very high purity single grain copper or silver. There are only a handful of companies in the world manufacturing via this method.
- PEF (Foamed Polyethylene). The foaming process uses a blowing agent, of which there are two types. Atlas use the gas-foamed method which creates a more inert, consistent and higher quality product.
- Central conductor (signal path) surrounded by dielectric material encased within a circular conducting screen which acts as the signal return path
