An update for this - ended up just running the h1n internals last night because I didn't get the 9v connectors in time and didn't want to risk the CA14s without the battery box. The recording actually came out pretty banger, I'm always impressed by the sound quality of those internal mics (there are quite a few GYBE shows taped w them)
Just picked up the 9v connectors, wired them back-to-back, and it seems to be working perfectly - hilarious.
For tonight, I'm gonna run CA14 > SUBB (Stupid & Ugly Battery Box) > r-05. Hopefully that works well
Once I ship off the BB back to Chris, I'll use these connectors to build my own BB!
