Cartridge loading is the act of putting a resistance (sometimes, a capacitor and a resistance) in parallel with the cartridge, such that the cartridge is driving the load.
We provided a cartridge loading strip on the back of our preamp for this purpose. Some preamps employ a second RCA connection in parallel with the input- you put the resistor on an RCA connector and plug it in.
Other preamps have a switch with preset loading positions. Still others use tiny little jacks mounted to the circuit board in the preamp.
Some phono preamps have no provision. Then you have to come up with something to make the connection.
