Title: Actual PIP DCV of Sony M-10 - anyone know?
Post by: groovon on July 06, 2010, 04:49:14 PM

Anyone measured actual DC off the mic input jack? Just wondering how well electrets will perform powered straight off the recorder...

Thanks!

Sorry, dumb question, I haven't got the recorder yet. Now I see it takes two AAs... so I expect the PIP supply doesn't amount to much more than a couple of volts. Looks like I'll need to make a battery box...

Thanks ms - yes, I'd have hoped for something more like that, but I just found a post where guysonic apparently measured 2.5V.

At least, that's what he says here: http://taperssection.com/index.php?topic=136665.msg1780607#msg1780607

cheers

Given how decent the mic preamps in the D-10 are said to be, and if so, all you need is 9-10v DC (@ possibly insignificant mA?) I wonder if an internal hack for boosting DC to the mic jack would be possible. Trouble is, the components in these things are getting so tiny they'll eventually be impossible for a normal person to work on (if they're not already). But I'm thinking, if not able to be inside the recorder, a teeny flat cellphone-type rechargeable, low-profile Li-ion cell virtually sculpted to the D-10 case, with a charging jack, and hard-wired back into the recorder's mic jack.. just a thought.
