Can I bypass the Mic Pres on the iD22 (and use my own mic pres)?
You can easily bypass the mic pres on iD22 by simply patching the output of your other mic preamps or gear into the insert return, which is a very pure differential line stage into the ADC, therefore completely bypassing the on-board mic pres / HPF and line input stage.
This would allow you to still use the excellent Audient mic preamps for other duties in the analogue domain (output available at the insert send jack).
