Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.
Download on the App StoreAudiobus is the app that makes the rest of your setup better.

Comments
Maybe they'd better stick with speakers/monitors...
I wouldn't want to load a mic with 100 Ohms... and 46 dB of gain isn't state of the art either.
(typicial mic input impedance is 1kOhm to 7kOhm, most are about 3kOhm)
