So I hooked up the contact mics with preamps to the fazley mute cymbals. The output is going through a Berhinger MX1604A (cheap second hand version ) and is mixed with SSD5 free hugo edition drum sounds controlled by my roland-TD6V module. The sound is not perfect and there's some distortion...

Yes, the question is: why are they lo-fi, why am I missing the high-end? is it the preamp? should I work with an opamp instead of a transistor? it seems the gain is enough with the transistor preamp. is it the mic? its a very cheap electret mic, I'm waiting for the primo EM172. Is it inherent...

Thanks, Both are interesting ideas. I've meddled a lot with piezo's as triggers for my DIY edrum (and indeed, I buy them for less than 1$), but I never used them as contact mic. But they are Lo-Fi and will alter the sound of the cymbals quite a lot I think. Also when you attach them to the...

I have another question: I want to power multiple preamp + electret circuits with the same power source. Would it be possible to send the mono audio signal and the V+ power supply with a stereo jack connection? I would try the following circuit, with multiple mic + preamp circuits in parallel...

OK, thanks, I found the circuits to make the output balanced. Am I correct in assuming that the only reason for a balanced output is eliminating noise picked up by the cable from the mic to the amp? Or do balanced lines have other advantages? Right now I'm using the circuit in my second post...

I might be wrong, but wouldn't the PMZ mic also record a lot of ambient sound? I'll be hitting mesh head drums and other cymbals very close by. I'm feeding the output of my preamp to the mic in of my roland quad capture audio interface. The phantom power is off, because the electret is powered...

OK, I discovered that the 7W amp is a really bad idea. Ik need a preamp of course. I used the following circuit This gives way better results, much less distortion when it's played loud. If I hook this up to an equalizer I might get some decent results. I also ordered a higher quality primo...

Hi, I'm trying to copy the Zildjian GEN16 AE cymbal system. They are using something they are calling a 'direct source pickup' to amplify low volume cymbals. With this system you get true electric cymbals (instead of a trigger - sample system). I think the 'direct source pickup' is an electret...
