Flexible Multicore System!

Need a 4-channel multicore of any length quickly? No problem! Pronomic's NetCore system transmits both analog and digital signals through a thin network cable.

Ingenious Technology

A Cat cable contains 4 pairs of wires - so 4 balanced audio signals can be carried in a single thin cable. The cable shielding acts as signal ground, so operation is only possible with shielded network cables. Since the NetCore system works with standard network cables, using an existing building network is also possible to route signals from one room to another. The prerequisite is direct wiring of the sockets – no switch or similar device may be in between.

Freely Combinable

The NetCore system includes several stageboxes, rack units, and snakes, each component can be connected to any other. It doesn’t get more flexible than this.

Applications

The uses of a NetCore line are very diverse, for example:

  • From drum kit to mixing console
  • From mixing console to monitors
  • As a submulticore for keyboards to mixing console
  • From DMX controller to lighting effects (4 DMX lines simultaneously)

You won’t find a more elegant and slim way to lay multicore. To avoid possible interference noise, we recommend using a NetCore line exclusively for either analog OR digital signals.

Simple, Practical, Cost-Effective!

Simply practical

My use case is to bring the signal from the IEM mixer rack to the rack with the transmitters.
So far everything has been solved with patchbays and 8-way jack cable whips. Takes up space in the rack, is prone to errors (once two plugs get mixed up and you have to search), weighs.

With transmission via Net Core, it is compact, lighter and foolproof with a network cable.

Workmanship is good. Sockets grip properly. The workmanship makes a high-quality and solid impression. A clear recommendation to buy!
I will now gradually start retrofitting exactly this product in the other racks and also in the studio. The fact that you can send Phantom over the line is also very practical.

Super tool - very flexible

Class tool. Very flexible thanks to parallel F/M sockets. I have ordered two more 4x whips (also split into M and F) so that I am equipped for all applications (submulticore for microphones but also submulticore for distributing active speakers on stage).
I can recommend it without hesitation. There is only a polarity change in the NetCore SB-3FM section via CAT cable to 4-whip. But you can also "fix" this with a soldering iron
Ideal solution

Ideal solution for assigning a maximum of 4 channels with only one cable. One audio signal to and 2 microphones back, even a DMX signal can be assigned in parallel. I got two for my soundcraft, 🔝
Great solution for permanent cabling in racks!
