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. umashankar
