i don't follow what the output of the mps6030 has to do with anything since the mps6030 has a single 1/8" mini output; the same connector you offer on your heb battery box[/url].
This is incorrect. Our HEB battery box has only a single locking mini-XLR jack that has both input and output signals on it. The output from our HEBs is a single 1/8" stereo miniplug (from Switchcraft -- the highest quality connector available), not a jack; it's at the end of a cable, not on the battery box. And we use it only because lots of mass market recorders use 1/8" for their mic inputs.
In general, the 1/8" miniplug/minijack is a crappy and unreliable connector -- that's why, given the choice, the pros use XLR, mini-XLR, Neutrik, Hirose, BNC, TNC or just about anything but 1/8".
...could it be you "forgot" about the other boxes because they just so happen to be in direct competition to your "heb" package?
If you'd like to provoke a fight, you won't get one from me.
DPA makes the finest miniature microphones in the world, bar none -- that's why we use them in our HEBs.
Some of their other products are not the best in the world, and though they're quite fine, sometimes they can be improved on in both function and price. When we can do it (and it's not often, simply because the folks at DPA are excellent engineers), we do.
