dear david
 
I forwarded your mail to embrace video people; I would like the page to sound 
meaningful. they showed me the copy, but I was always a lousy proof reader. as 
to the preamp, the plan is to provide a small box with a five pin tuchel on one 
side and five xlrs or mini xlrs on the other. it should be possible to power it 
either with an internal 9 volt battery or with phantom. there is also a plan 
for a variant for unbalanced outputs, the box providing very low impedance 
capable of driving long cables and better dynamic range than pip. I have 
breadboarded the circuits and at the moment doing the pcb layouts.
