New Information for me, After more research are learned there are 25 adjustable pre-amp settings on the H2. 20 below zero or negative dB and 5 above zero. So same scenario as above, I set the X-H2 external Pre 5 clicks up from the least preamp level of -30, to -22.5, and I now have plenty of gain at 50% on the DXA-Max, and the Rode SVMIC Pro is at 0 gain. All other settings are as others have posted, internal mic off, Jack is on Mic not line, and the gain is on manual. If I increase the DXA to max, it will actually clip. I will see how this will affect video audio quality in the future, but I think running the H2 preamp at 25% below zero should minimixe its work and hiss. The new mics I have coming are small condenser, and have sensitivity similar to the Rode SVMIC Pro. They will be good for close micing of instruments, piano, singing but are not sensitive for distance. So trying to figure out the gain I'll need is important. Hope this helps someone else:-)
