hi all,
I have this mic, Sony ECMMS907 Digital Recording Microphone. I use it for field/ remote recordings through a minidisc player which provides it with Plug in power. The mic does not function through a mixing desk, with or without phantom power. I know this is normal. Id like to be able to use the mic in my studio and run it straight into pro tools hardware. AT the moment I have to run it into the minidisc, then run an output from the minidisc to the desk.
Is there a simple, clean, discrete preamp I can build so I can use this mic in a studio situation? schematic would be good - vero would be even better :)
Thanks in advance
I just did this one the other day:

Worked fine
here is another one:

The ECM-MS907 has preamps built-in. And is stereo. The plan you show would require much internal hacking.
The manual I found (http://support.sony-asia.com.edgesuite.net/consumer/IM/3858569131.pdf) shows a battery holder for a AA batt which will run 200 hours. Unless you are bugging your enemies, that's gotta be cheaper and quicker (and less hum) than any external rig-up.
Innerestingly the sheet does not say anything about getting power from a DiscMan.
To use it in studio you will need a semi-custom adapter from stereo-mini to two separate outputs.
Looking at the manual (thanks Paul) I believe I own one of these, I bought it to bootleg concerts with my WM-D6C (Pro Walkman.) If it's the same one, it works wonderfully well off a battery.
Gotta look for & digitize my excellent Stevie Wonder recording from Radio City - he brought Take6 up on stage for a couple of numbers, they were just getting launched. Great concert...
