Velleman Microphone Preamp Kit
Can a condenser mic element be hooked to this preamp?
yes, but only if the condenser mic utilizes an external phantom power source.

I know this says it's rated for 10-30 volts. Is there any way to make it work on a 9v battery?
This preamp should "work" on 9 volts, but you may not get the maximum amount of gain specified.

If I am using this with a board amp that requires a power supply as well, can I use just one for both somehow?
Yes, as long as both devices work with the same power input. You just simply split the output from the power supply.

Does this provide the 48V phantom power for the microphone?
Does this provide the 48V phantom power for an XLR microphone? Or is that something separate I have to get for the mic?
Using this will require a separate phantom power supply for your mic as this does not output phantom power. In fact, this requires it's own 10-30 volt power supply that is not provided with the kit. There are some microphone preamps here on PE that are reasonably priced and provide phantom power. The first one I list below is a small low cost single channel one that provides 21-30 volts of phantom power (this is usually plenty). The second one is a nice 2 mic set up that provides a full 48 volts of phantom power.Or, if you want to use this Velleman kit, you can find some DIY schematics for building your own phantom power supply with a little Googling.

The mic has batteries and is plugged into correct jack. . .any ideas???
I bought this type for use in my computer which does have a stereo input jack. The mic is powered by batteries instead of a mic jack power source. I contacted Tascam and they suggested a mic pre-amp. This surprised me since cheaper mics have better gain while this Tascam has to be yelled into. My question is. . .could this plate pre-amp work if I used two to maintain the stereo recording.Thanx in advance if you have a clue. I have also tried USB mics but I'm running Window XP Professional so it requires a driver and will not 'sense' a driver when a hardware device is plugged in.
This pre-amp should work fine as a pair. First, though, check the volume settings on your computer. If a cheaper, higher-gain microphone has been plugged in, the computer may have turned its own volume down to compensate.

Boosting electret microphone
would this product be suitable for boosting an electret microphone signal (3 ohms) to line level (10 ohms)? The speaker amp I am using is line level input only..
Yes this preamp will work for this application.
