I've heard mentioned that some recorders, including the M10, can't supply e=
nough voltage to two pairs of EM-172s, which leads to at least some reducti=
on in this benefit. I don't know how much of the benefit is lost. I'm using=
 an M10 with two pairs of capsules in a similar array to Vicki's on the cap=
erteebirder site, but I haven't got around to comparing it with a single pa=
ir. It sounds ok to me.=0D

Perhaps someone who understands it better could elaborate on the effects of=
 the voltage drop?=0D

One gets a 6 dB signal gain from the adding the output of the two capsules =
together, but the capsule self-noise which is uncorrelated will only increa=
se by 3 dB. So the net result is a signal to noise gain of about 3 dB for a=
 two-capsule vs. one-capsule mic channel.=0D
