Mavros dd BNC

Our finest wide bandwidth S/PDIF cable, designed to be technically and sonically superior, without the typical noise-related ‘glare’ freqently found in inferior cables. New for 2020, we’ve made some significant upgrades to the original specification, not least a revised conductor arrangement – now using OCC rather than OFC – and our dd (‘dual drain’) system. Recommended for use whenever signal integrity is paramount, for example between digital transport and DAC.

A true reference class 75 Ohm digital cable.

The Mavros BNC cable is engineered as a cable with extremely precise transmission and termination standards, incorporating the same microporous PTFE (Teflon™) dielectric insulation as the other Mavros interconnects.

The centre conductor is comprised of a monofilament conductor and 18 strands of super pure copper wire insulated by a thin layer of microporous PTFE. This new dielectric behaves almost like the theoretically perfect insulator –free air – with minimal effect upon the signal being transmitted. The previous highest performance insulator, solid PTFE, has a dielectric constant of around 2.1 whilst the new PTFE (Teflon™) foam improves this figure to around 1.5, providing for a 30% greater signal velocity and better signal integrity, particularly in the area of high frequency timing and stability.

The co-axial double shielding layers are an aluminium Mylar™ foil followed by OFC (Oxygen Free Copper) braiding after which the whole cable is protected by a PVC jacket damped with cotton yarn. Our unique dd system connects the screen effectively to the cable return/plug interface, meaning the cable can be terminated without distorting, twisting or mechanically stressing the precision-laid screen. The benefits are in maintaining a consistent low impedance load to the plug, and a total 360° screening against noise and signal loss caused by RFI (Radio Frequency Interference).

With a termination impedance of almost exactly 75 Ohms at 1 MHz and a low conductor-to-conductor capacitance of around 50 pF per meter the Mavros BNC interconnect perfectly matches consumer digital audio equipment to ensure error-free transmission of high speed digital signals. The result is evident in the timing and dynamic range of musical performances where the temporal ‘smearing’ of lesser cables is absent.
