7/31/2019 Van Den Hul - Ground End Marking Stickers

1/1

Grou nd- End Mark ing St i cke rs

As from May 1999 all our screened twin core, quadruple core and triaxial (i.e. balanced)

interconnects that are ready-made with RCA type connectors for unbalanced/asymmetric

signal transport are equipped with ground-end marking stickers.

This to provide additional indication regarding the side of the cable at which the shield is connected to the RCA connectors

shell (= ground). With these cables our standard rule that the shields grounded end is at the left side of the cable when

holding the cable such that its type printing can be read is maintained.

With these cables already one of the internal conductors functions as signal return, connecting between signal source and

receiver ground (see the illustration at the bott om of t his page). In connecting the shield to ground only at one side of the

cable and lifting it at the other side it functions as a true screen: It does not carry any audio signal; It screens the inner

conductors and drains away unwanted noise to one location. This location (marked by the ground-end sticker) generally is

chosen to be the signal sources ground (*), however in a few cases better shielding performance can be obtained by

reversing the cable, thus grounding the shield at the signal receiving side.

Please note that reversing the cable here has nothing to do with the sometimes used term cable directionality; In van

den Hul cables this effect is absent.

Burn in effects and directionality found with some audio cables also partly can be pointed towards polluted contacts; For

optimal contact care we therefore recommend our The SOLUTION contact fluid.

* : Here, tying the shield at the source end rather t han at t he receive end has the potential advantage of a reduction in

the coupling of ambient electromagnetic high frequency noise into the audio signal due to possible "line to shield"
