So no compression if the unit is not actually recording? That would make sense. Anyway, I did some experimenting last night (not really related to MD, but thought I'd share anyway): Recorded from my stereo speakers first through the Sharp702 with level near 0dB, to the JB3 at 0gain, +4gain, +8gain, and +12 gain. Then went directly to the JB3 with mic-in, and then line-in. Seems the mic-in and line-in are really the same on the JB3, with the mic-in just allowing for a gain up to +48, where line-in only let's you go up to +12. In a nut shell, the least noisiest recording came through the Sharp MD at +12 gain on the JB3. It clipped a bit, but was nice and loud. Downside is the level meter on the JB3 is horrendous. The meter didn't indicate clipping but it sure as hell was. Anyone out there know of a separate level meter? The MD meters are generally pretty good, so I'm guessing that most folks wouldn't be interested. Anyway, thanks for the input daniel!
