I wish to connect an instrument transducer to the input of the iRig Pro, supplying it with phantom power from the iRig Pro itself, and the output to an audio amplifier. This amplifier has 1/4" input plug. (I could use a 3.5mm to 1/4" converter, the size is not the issue.) What I don't know is if an adaptor exists to convert the lightning or the USB ports in the output cable of the iRig Pro to an audio jack.
Or, if a separate cable exists (from IK Multimedia or otherwise) with the mini-DIN socket in one end (for the iRig Pro output) and an audio jack on the other end.
The setup above would provide me with a portable preamp which can supply phantom power. Many thanks.
