nextgen™ - new generation of WBT RCA connectors
» more about the awards
The basic element having influence on the sound quality of WBT-0152 Cu is the Central Contact Unit which has been developed exactly the same way as for the plug model WBT-0110 Cu: minimal mass of signal conductors made of highly pure copper. Copper was chosen as one of the best electrical conductors which provide not only an ultra rapid signal transmission, but also an excellent fine resolution. This metal is of course nickel-free gold plated so that the surface does not oxidize which would affect the contact quality.
WBT-0152 Cu lies with its transmission bandwidth of up to 200 MHz far in excess of the transmission bandwidth of conventional RCA plugs.
Through the collect chuck device which works like a chuck of a drill machine the plug’s outer contact once inserted clamps firmly to the RCA socket. The maximum contact pressure provides not only a secure connection, but also minimizes the transition resistance.
Thanks to the two-piece clamping sleeve the sleeve’s cone does not turn while the clamping sleeve is tightened and thus the contact elements are not exposed to twisting pressure. Besides, this way dimension inaccuracy of the outer contacts of the female sockets are compensated for.
The centre pin is slotted and slightly bent up and thus guarantees with its firm spring feature a long-lasting secure electrical connection with lowest transition resistance possible.
The body element is made of brass (nickel-free gold plated) in order to accept rigid and particularly thick cables. The metal connector body is of course electrically uncoupled from the central contact unit und is made of as little metal as possible so that also WBT-0152 Cu is free from eddy current to a large extent.
Other than for digital outputs it is very important for phono outputs (record players, microphones) to have a good shielding against electromagnetic interfering fields. The undesirable interspersions can be very high depending on the nature of the devices and first of all on what they are surrounded by (cellular phones, computers etc.). WBT-0110 nextgen™ pure was designed as the perfect RCA plug for digital links, the new WBT-0152 Cu optimizes analogue connections. WBT-0152 Cu has the more conductive and with the minus contact element connected brass clamping sleeve in order to provide the necessary electromagnetic shielding.
For soldering your cable WBT recommends using silver solder WBT-0800 (see also solder connection) which is gentle on the surface.
Torx screw provides a secure cable strain relief. (The position of the Torx screw on the plug´s round shaft can vary depending on the production process).
