Heyup,
I know comparatively little about electronics, so please bear with me!
I've been working on a little project to record sound with my Zen MP3 player, which has the ability to record at 160kbs. However, it only has a line in, so to get sound from a mic, it needs to be amplified.
Now, I've got it pretty much sorted by using the pre-amp and amp circuit from one of those REALLY old Sony Walkmans, and a little circuit to power the electret capsules. Although this works very well, and the resulting sound is more than I could have hoped for, there is WAY (!) too much bass. Although it can be EQ'd in editing software, it makes the signal overload very easily.
Is it possible to make a simple high-pass filter for the mics before they enter the amp, and would it solve the problem?
Also, why exactly is this happening? Could the amp be boosting the low frequencies for some reason?
Thanks!
