they do not have three mics in the zoom. there are four, and a friend of mine 
tells me the capsules actually sound quite good. there is a front pair, two 
cardioids at 90 degrees, and a rear pair, with the cardioids at 120 degrees. 
from the photos i have seen, each capsule is soldered with two wires, and my 
aim is to extend these wires and connect a sound-field like microphone array - 
if the capsules are really good i might make the array out of them, otherwise i 
was planning to use tsb 120s, which are excellent.

there is a 2.5 volt pip available, and i think it can be switched off if needed.

of course, you can produce 5.1 out of the existing four mics without mods. as i 
said, daniel courville has published a vst plug in (as far as i can tell, only 
for apple) and that would be the simplest solution, especially if the capsules 
turn out to be good.

I saw that some folks on the SurSound list are looking into ways of 
inserting their own mics into the H2's circuit. I think that 
Terence's mics on the Holophone HD3 are all omni-directional, but 
they might be a good match for the H2 mic pre. Do you have a theory 
about the array/processing Samson is using to produce the two stereo 
pair tracks from the three, built-in mics?  Rob D.
