> The Tetramic spec declares 3.5mA x 4 capsules (=15mA) @48V - that's 720mW
> But to power through the PPac it's 9-12V @<10mA - that's 90- 120mW - a big difference. The P48V current consumption is pessimistic. Powering directly bypasses the regulation required for P48V. You also avoid noisy P48V in some (many?) prosumer recorders though PPAc is pretty immune to this. It was designed with wall plug adaptors in mind but do check out the one you want to use. I use an alkaline PP3 rubber banded to the PPAc. Make sure you have the correct connector. For an important recording, use a new ALKALINE PP3. Probably 10 hrs life http://data.energizer.com/PDFs/522.pdf I regard batteries as consumables and the cost is trivial. I do stage sound and find it easier to use new batteries than to try & ensure 24 batteries for 12 radio mikes are all fully charged. A bag of PP3s costs less and will weigh less than chargers etc But really anything which will supply 9-12VDC will do. I've suggested to Len we sell a deluxe PP3 connector with O2-free Cu, insulated with the scrotums of Cooktown kangaroos, all hand carved from solid Unobtainium by Virgins .. shut up Lee ... just SHUT UP! _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
