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.

Compact headphones preamp with two outputs and individual level knobs
I’m searching for a very compact battery powered headphones preamp with two HP outputs and individual level knobs.
The goal is being able to use my iPhone with iRig Pro IO (one 3.5 mm output) with IEM and battery powered PA speaker with individual levels.
There is M-Audio bass traveler, but no individual knobs per output:

@ToMess
Thanks, the first one seems to be a good solution to complement M-Audio Bass traveler, for lowering IEM level and keep an output at max/higher level for PA speaker. I have to try that.
@McDtracy
Thanks too, seems to be a good solution for sound quality but I need something as compact as possible as all that gear will be mostly on my belt, etc for that project.
If that don’t works well, I’ll go for an iRig Pro Duo.
I keep forgetting your model... wireless, stand-up, mobile.
I have a iRig guitar input that and I velcro'ed an iPhone to a Fender Telecaster and use some short cables to keep it clean and strap on the Tele' and I can play/practice while I take walks
using headphones. I could strap a speaker to my belt and busk with this rig. I'd love to see a video of your rig when you take this next step in your design.
You light open eyes of many instrumentalists with your mobile approach and sophisticated "band" playing along.
