The basic element influencing the sound quality of the WBT-0102Cu is the central contact, here using pure Copper, chosen for its excellent electrical conductivity, guaranteeing perfect signal transmission. This contact is gold plated to give it a high resistance to oxidation.

The WBT-0102Cu supports a transmission bandwidth of up to 200MHz, a much higher value than traditional RCA plugs.

The clamping system, functioning like the chuck of a drill, allows a firm hold of the connector. The maximum contact pressure not only ensures a secure connection but also minimizes transition resistance.

The two-part clamping tube ensures that no part of the connector can move so that the contact areas are not exposed to torsional pressure. In addition, this method compensates for potential inaccuracies in the dimensions of the outer contacts of the sockets.

The center pin is split and slightly bent to ensure a secure and durable connection with the lowest possible transition resistance.

The body of the connector is made of a copper alloy with gold plating and can accept thick, rigid cables. The metal body is, of course, electrically insulated from the contact area and uses a very small amount of metal to cancel eddy currents.

Finally, the WBT-0102Cu has electromagnetic shielding, which is particularly important for analog connections.
