The IK Multimedia iRig Keys I/O MIDI Keyboard is a 49-key MIDI controller with microphone and instrument inputs. The microphone input is balanced, with a 3-pin XLR connector and +48 V ± 4 V phantom power, while the instrument input is unbalanced Hi-Z with a 1/4" TS connector.

The two balanced line outputs use 1/4" TRS connectors and automatically compensate the level when used with an unbalanced connection.
