These boards can be used as cascadable multiples, to create trunk lines between different cabinets, or assuming you have something else that uses the same termination, for expansion/breakout. It uses 16 way ribbon, like used in Euro power, every second wire connected to ground to form a shield between the signal wires. You can mount one of these in each cabinet of a large system, and hook them up from behind with the ribbon. If you hook just two in different cabinets together, you have 8 trunk lines between them, reducing the need for long patch cables. If you place one in each of several cabinets, and run a common ribbon between them, then you have an inter-cabinet bus. If you mount them side by side, and use a common ribbon between them, you have a multiple. As a bonus, the board is designed to work with banana jacks as well, so your bus/trunk lines can go between different types of synths (mini jacks and bananas).
Before you start assembly, check the board for etching faults. Look for any shorts between tracks, or open circuits due to over etching. Take this opportunity to sand the edges of the board if needed, removing any splinters or rough edges.
Jack centers are at 1/2" spacing. The board will fit behind Euro and Frac rack panels.
If using banana jacks with the Euro panel, the jacks need to be mounted on the other side. A small portion needs to be trimmed from the tab of the jack to prevent it shorting against other tracks. See the photos above.
The panel has two sides, one labeled 1-8 the other A-H.
Note that you may need to open the holes out to 8mm to get your jacks to fit.
