whats the differemce between a Preamp and battery module?

[Guest Anonymous]

I Have a sharp dr420.

I was wondering..

1)whether I really need a preamp or battery module for decent far off recording

2) Is the minidisc by itself enough to power these cardioid mics?

Thanks

A battery module would generally be used for loud recording sutuations (eg. rock concerts) so as not to overload the recording levels. A pre-amp would be used where the recorder doesn't have one, or to by-pass the built in mic-pre-amp for better quality.

As Sharps have quite good mic pre-amps built in, you probably won't need one initially, especially if your mic is a good one. Your cardioids, being uni-directional would be good for recording sounds at a distance. Experiment with the recording volume and you could be pleasantly surprised....
