Product description:

Less is more - WBT nextgen™ products are convincing proof of this.

The new WBT-0703 nextgen™ pole terminal preserve valuable resources of non-ferrous metals and conduct signals and sounds – not however, rather exactly for this reason - better than any other before them.

With the new WBT-0703 nextgen™ pole terminal, we have succeeded in offering the standard-bearing nextgen™ technology at an extremely attractive price. The new model is nextgen™ through and through and therefore provide faithful signal transfer and an authentic sound experience.

The signal conductor of the WBT-0703 nextgen™ pole terminal is restricted to as low metal mass as possible consisting of pure copper. This does not simply preserve valuable resources, but also eliminates losses in sound quality owing to the mass storage effect. This effect is unavoidable with larger metal masses and has a measurable influence on signal flow. The innovative geometry of the conductors in the nextgen™ pole terminals also prevents eddy currents effectively which can affect the purity of the signal. Eddy currents occur in the form of nonlinear distortion and cannot be corrected.

But the innovations by no means stop here. The form of the signal conductor doesn‘t just act again the mass storage effect and eddy currents, it has also been optimised over the course of complex tests and calculations so that the new nextgen™ pole terminal is significantly more resistant than conventional models to microvibrations through structureborne sound.
This means that nextgen™ pole terminals offer an unrivalled level of transfer safety and, in conjunction with the WBT-0718 nextgen™ impact sound interrupter, define the boundaries of what is technically possible.

Another innovation is the moment of force indicator integrated into the pole terminals. This provides an acoustic signal when there is sufficient contact pressure to the sandwich spades. It is a popular misconception that signal transfer is only at its optimum level if the maximum possible contact pressure is exerted on the contact surfaces. If these surfaces are pressed against each other too tightly, parts of the surfaces can be damaged beyond repair.

That being said, nextgen™ pole terminals give you a free choice as to contact pressure. Alongside the signal conductor, another decisive factors for the quality and long lifespan of the nextgen™ pole terminals is the interaction between the different materials.

In terms of robustness, nextgen™ pole terminals don‘t play second fiddle to classic metal models – in fact, they are far superior.

Explanatory notes:

External connection
The smart design of the signal conductor enables a secure termination of cable ends, banana plugs and crimped cable ends.

Internal connection
Soldering lugs which can be bent by hand if necessary. WBT recommends application of the silver solder WBT-0800/0805 which is gentle to the precious surfaces.

Mounting
WBT recommends using the impact sound interrupter WBT-0718.

Hint for equipment manufacturers
Due to the valid safety regulations the 4mm banana holes of WBT pole terminals being used in the field of audio/video within the EU territory have to be closed with the safety stick WBT-0799.
