Interesting concept.

Perhaps the idea behind the two capsules is to get extended dynamic 
range from the dynamic element and high-end "bite" on the slap from 
the condenser element. Has two outputs. I guess it would require four 
channels to record stereo.

I see that the self-noise for the condenser element is rated at 68 
dB, 1 kHz at 1 Pa or 26dB(A). The sensitivity is 3.5 mV)/Pa. 
Self-noise of 16dB(A)  and sensitivity of at least 10mV/Pa  might  be 
regarded as borderline  performance for recording ambience in quiet 
locations. There are always surprises but it seems unlikely this will 
be one.  Very well suited for loud sounds,.. 148 dB SPL.  On the 
other hand, I'd like to see better low-end response in a mic for a 
bass drum,.. Rob D.
