Hi hann...
Channel 2 on an EDB-1 would work fine for pre-amplifying two passive sources. The internal mic requires phantom power to work, which is only supplied by channel 1.

Many companies wire their preamps with the assumption that we will be using a dual source with one passive pickup and a phantom powered mic.

This is not the approach taken by Headway.
