K551x by Labo ★ K Effects

The 500 format created by API allows the use of different preamplifier modules, compressors... in the same box that provides the supply voltages and inputs/outputs. A new 51X standard has been introduced to provide additional options by using an 18-pin connector. This allows to add the necessary +/- 24V voltages to some modules while maintaining compatibility with modules typically in 500 format. We can go even further by making the backplane modular. This is why Labo K Effects has studied the problem and is able to offer different types of backplanes for the 500 enclosures, using 18-pin connectors to be compatible with the 500 and X51 standards. They have been named the K551X. These backplanes are connected to the power supply via a ribbon cable. This makes backplane configurations easy to modify and opens up new possibilities for developers. (API is a registered trademark of Automated Processes Incorporated)
