Jumper functions
In order to maximize the VPS’s performance, the path of the (very low and
therefore sensitive) phono signal has been shortened as much as possible. This is
why the jumpers are very tight and close to the inputs.
We hope you will find that the manipulation difficulties are far outweighed by the
VPS’s quality.
Make sure that you are facing the phono module when setting the jumpers, in
order to have good access and a good view of the serigraphy.
We advise you to use the supplied jumper pliers to make changes.

Load circuits
The Nagra VPS is supplied with 6 load circuits, 3 resistive loads (R) and 3
capacitive loads (C), allowing the settings of your VPS to most closely match the
specifications of your cartridge manufacturer.
For each input module, Nagra offers you three free optional*, load circuits,
individually tailored according to your wishes. Please contact your Nagra dealer
for more information.
*Offer valid for a limited period following your purchase, please contact your
Nagra dealer.
You can choose the load circuit to be installed according to the technical
characteristics of your cartridge. (Please refer to the relevant manufacturer’s
data).
Each load circuit is numbered
and matches precise load values,
referenced in the card supplied in
the box.
While waiting for the custom circuits, you can use the closest load value to that
specified by the cartridge manufacturer.
