Low Voltage Wiring

January 3, 2024

Over the last couple weeks I finally got around to finishing up the low voltage wiring.

All the analog audio runs terminate at a floor box behind the desk, so I started there.

I tested each run to ensure the labels were correct and then soldered into the back of the floor box panel.

I used Neutrik NC3FD-L-B-1 and NC3MD-L-B-1 connectors for the audio lines and NE8FDX-Y6-B connectors for the ethernet lines.

There are 8 sends, 8 returns and 2 ethernet lines, for a total of 18 connections.

I used black label tape with white text to create the labels for each connector.

There’s another matching floor box nearby with power in it. I wanted to keep them separate to avoid EMI issues.

There are 24 ethernet lines running throughout the studio, each of which could carry networking, audio or video signals.

As I hooked up each plate, I used the label maker to identify what’s going where.

I had to split these into two boxes since there’s a double 2×6 column in the center of the wall.

The black screw-less plates look slick, but also leave a nice surface for labels.

The cable raceways are made by Kable Kontrol, and provide a robust, if not overkill, way to route cables around.

With the audio and ethernet lines complete, it was time to build a couple audio snakes.

These are Neutrik XX series connectors paired with Neutrik color-coded boots. The multicore cable is made by Canare and everyhing gets covered in TechFlex.

I made two 8 channel snakes, one with male and another with female XLR connections.

I used Neutrik NP3X-B TRS jacks with gold plated contacts on one end and Neutrik NC3MXX-B and NC3FXX-B XLR jacks with gold plated connectors on the other.

The snakes will run to a TRS patch bay, where I can then use patch cables to route audio around the studio.
