when I record with my battery box/mics there seems to be some background noise and very low levels...compared to my Iriver. Maybe a preamp or more sensitive mics would give better results?
Yeah, I guess that is what Todd who wrote the guide also concluded. Like the JB3, the internal gain is noisy and insufficient.
From what I understand, the JB1 doesn't have digi-in, so you have to rely on the internal AD, which probably is another weak spot contributing to the noise?!
But kudos for doing the CF mod! How much does the adapter cost these days?
