I’m looking to hook up an external XLR microphone to the Iphone... Any thoughts on adaptors for this? It seems people all over the web are looking for the same thing.

Such as this self powered mic:

Or a typical Shure sm57:

I would assume we need an XLR>Minipin adaptor, but not sure of line level, etc.

TIA!

They also make any cable custom, just email them!

Actulaly, you may want to consider using a "Zoom" for recording multitrack audio via it's built-in mics and XLR inputs. Then, you bring it into your post editing system and synch to the video you shot in the iphone using Plural eyes from Singular Software. A lot of folks are doing this with the DSLR cameras... why not take a page from their book.

Chip, That's what I've been doing and it works great.
