Some Klark Teknik units are fitted with combination ports as shown in the center of the diagram above. This style port is capable of taking both jack plugs and XLR plugs, thus reducing the physical size of the product to accommodate both types of port and reducing the cost of the product to end users.

It is worth noting that the port will only allow 48v/phantom power when a balance XLR cable is fitted, it will not work via a standard jack cable.
