Excalibur is Supra Cables' flagship USB audio cable, featuring OFC conductors with a 3.8% silver plating for optimal transmission of high frequencies and high speed data transfer. This cable also features separate and carefully designed conductors for data and power, meaning that both pairs are optimised for performance and to reduce crosstalk and RFI.
Supra have for a couple of years been developing an ultimate USB Cable, the result was USB Excalibur. Their goal was simple: to make the world's best USB cable, with no compromises or shortcuts. Excalibur is a premium high speed cable with improved data and power transmission, a complement to the existing USB series.
Supra USB Excalibur is supplied in a black presentation bag, but you can use it to help protect the cable, if used in portable/remote situations.
Both the data pair and the power pair are optimised for their purpose, as the demands to transmit data and power are different.
The twisted data pair is made of PE insulated Silver-plated Oxygen Free Copper wires. The Silver layer is very thick, 3.8% of the total wire, for best conductivity and high velocity factor. Silver is great for high frequencies and high speed data transmission.
USB Excalibur, is optimised to handle 24-bit HD Audio and it's 90 Ohm characteristic impedance results in low attenuation.
The construction of the power conductors are totally different compared to the data pair. To avoid power losses and to maximize the conductor area we used 4 Tin-plated OFC wires in a star quad configuration. Star quad design and the seperate screen reduces any RFI greatly .
You probably recognise the design of the plugs - the USB plugs are siblings to our popular HDMI plug. Fully shielded in Aluminium.
The plugs are detachable to make it possible to route the cable within in 16 millimeter conduits including the contact. No more on-site cut-offs and re-soldering, jeopardising the typical Supra top notch performance.
The connectors use aluminium housings to withstand tough applications and long term use.
Maximum Data Transfer Rate: 480 Mbits/second (as per USB 2.0 specifications).
Please note: While USB 2.0 and 3.0 are physically and electrically compatible, USB 3.0 is a dual-link system that is not currently used for USB Audio.
