PANASONIC WM 61A REPLACEMENT MOD
The Linkwitz mod involves cutting the connection on the capsule between the case and the "source" connection. Note that if you remove R12 and R13, you need to replace them with jumpers,or the output will be disconnected from the XLR connector! Also, note that the stock ecm capsule has been replaced with a Panasonic WM-61A with the Linkwitz mod. You will notice that the original 6 volt zener diode has been replaced with a 12 volt zener diode. I left things in the same relative positions so that you can easily spot removed parts. The good news, is that for recording we can get rid of about half of them!īelow is the modified schematic for the ECM8000, which I would argue, is no longer an ECM8000 mic. But, remember, Behringer designs these for measurement purposes, so a lot of those parts are designed for stability under any conditions. If the schematic looks "busy", you are right. And, it turns out that you can swap capsules and modify the mic's electronics to turn it into a much better mic!īelow is the schematic for the ECM8000 as Behringer builds it. This is where things start to get interesting.Īs it happens, Behringer builds the ECM8000 with a Panasonic capsule. It turns out to be fairly easy, although a delicate operation, to dramatically improve this mic, boosting it into the realm of far more expensive mics. However, since it is intended for measurement purposes and not recording, the designers have optimized it for the measurement task. The Behringer ECM8000 measurement microphone is a very inexpensive phantom powered condenser microphone that performs well for the price right out of the box. The frequency response is flat from 20 to 20K hz! And, for most purposes it is quiet enough. The Panasonic WM-61A condenser mic capsule is very inexpensive and provides excellent performance, especially if you apply the Linkwitz mod. And, sooner or later, you'll find out that the two items overlap. The other is information on the Behringer ECM8000 measurement microphone. One is information on using electret condenser microphone (ECM) capsules such as the Panasonic WM-61A, and applying the Linkwitz mod to it. If you look around the Internet for information on building microphones, sooner or later you will run across two things. So, read on, you too may be able to construct for yourself a versatile recording Of information about building a surprisingly good, yet inexpensive microphone. In the process of going that rout, I gathered a lot But, for most of us, we have toīut, for those among us who might be handy with building things, there isĪnother alternative. And, let's face it, if we could allĪfford a Neumann U87 we'd be all set. And specific examples, such as Rode NT1, audio-technica AT4040, AKG C414, Neumann TLM103, Neumann U87, shure SM57, etc., all great mics for their intended purpose. Manyįine examples exist from various manufacturers, AKG, Shure, Neumann, audio-tecnica,Įarthworks, Rode.just to name a few. So, the beginning of a good audio chain is always the microphone. Naturally, you cannot expect your recordings to sound good if the microphone picks up sound poorly. Good recording is totally dependent on the quality of the microphones you use.
