If your mic is the Presonus M7 Condenser mic, it uses an xlr cable and is not a USB mic and it also has to have 48v phantom voltage.

To plug the M7 into the looper you will need to route the M7 through either a DI box that also provides phantom power or a mixer that provides phantom power and feed that output into the looper. In order to utilize the stereo effects created by the looper you will need a 1/4" stereo splitter cable for the ditto's input and output. Recording looped vocals, and not applying any stereo effects, use the mono input and output. The audiobox input will accept a 1/4" mono input, so a 1/4" - 1/4" mono cable would work. If you use a standard guitar chord, use the shortest length that is practical.

You can buy a xlr-1/4" adapter but that does not provide the phantom power to the M7 and so that will not work.
