WBT -0144 Quick Start Manual

Coaxial Plug WBT-O 144
RCA plug (1 6 ohms) for cables up to 9 mm dia.,
for soldering
Made in Germany Int. Patent. 0460145
To achieve the best possible results from the individual components of
a HiFi system, you need optimum connections. lt's not so much the
cable you use which is decisive but the connectors, since it is at the
contact points between cable and system that most transmission loss
occurs.
For this reason, WBT has developed plugs and sockets for audio
systems tar superior to the standard types available. WBT quality
connectors are made from a special OFC copper alloy and ideally pro-

addrtionally ensures constant dielectric properties. WBT RCA plugs
and sockets are matched for a unified surge impedance of 16 ohms
which qualified them to form adapted connections when the system
cable WBT-2016 is used.
Even more important than the material used are the mechanical pro-
perties of a connector. The decisive factor is a high and reliable contact
pressure, created for example by clamping or spring mechanisms:
A precisely manufactured connector alone can fulfill these require-
ments. A connector made of solid material (tolerance < 51100 mm)
additionally guarantees extremely low and reliably reproducible
contact resistances.
The contact quality of conventional RCA pin-plug connectors is un-
deniably poor. The reason for this is a lack of standardisation.
WBT trial
measurements have shown, for example, that the diameter of the out-
side contacts of RCA sockets varies f rom 7.95 to 8.55 mm ! An ideal
pin-plug connector can therefore never be a perfect fit but must be
adaptable,_This problem tvas solved bv WBTJong ago: - -- --
- due to the (patented) collet chucking device, which works in the
same way as the chuck of a power drill, WBT coaxial plugs can be
adjusted to fit phono sockets of all kinds. The lamellas of the outer
plug contact can be narrowed down to fit any socket by turning the
plug sleeve. This not only ensures uniformly high contact pressure
but also clamps the plug firmly to the socket.
- The spring path of the fourfold slotted inside contact is such that
the necessary contact pressure is reliably created even in the widest
of sockets.
- Intelligent contact arrangement: when WBT plugs are used in
conjunction with WBT coaxial sockets, this ensures that the outside
conductors are activated before the inside conductors, thus preven-
ting unwanted voltage peaks.
