Small list, for now, of the various microphones I have that are relatively interesting.
## LEM DO 42
Dynamic Lavalier Microphone.
Some brochure [here](http://www.retronik.fr/Audiovideo/LEM/LEM_Catalogue.pdf), see page 5 for the DO42.
- Bandwidth: 40 - 18.000 Hz
- Omnidirectional with some attenuations above 8000 Hz for a 90° angle
- Impedance at 1 KHz: 200Ohm +-20%
- Connector: 3m wire with XLR

## LEM 307
"Anti-directional" microphone.
Some more informations: [here](https://www.doctsf.com/lem-307/f16504) and the [datasheet](https://archives.doctsf.com/documents/feuilleter_document.php?num_doc=25008&ref=16504).
Mine is an "High Impedance" one.
- Bandwidth: 50 - 10.000 Hz += 6dB
- Output: -57dB (1.5mV in open circuit) for 1bar pressure
- Impedance: 80000Ohm, for direct usage
- Connector: screw-on circular connector (Adapter to be tested: "Switchcraft 2501F")
