Fidelity Sound - Color Coded Multipins
Here's an example of how color-coding your gear makes setup a lot easier.
On this panel, designed by Mark Johnson of Fidelity Sound in Virginia Beach VA, custom engraved colored squares are sandwiched behind each of the W5 MicroMASS chassis connectors.
The corresponding fanouts (not shown) have matching colored snakeskin applied to them - setup is as easy as connecting the same colors to each other.
