For ambiances recording, I almost always use the LCR setup in the Cinela blimp, this setup is composed of a Sennheiser MKH 8040 ORTF setup + 1 MKH 8050 added for ” Center ” channel, which is really nice to have once in the edit room.
I often add the excellent LOM Usi omni microphones to get another sonic perspective and more edit possibilities afterwards, so I came up with the idea of mouting the Usi mics inside the Cinela basket in a unorthodox “AB” configuration.
please note that I didn’t use the ” center MKH 8050″ in the examples below and that the Usi are plugged into the 3.5mm AUX input on the MixPre-6, the preamps are a bit noisier than on the normal XLR inputs in which the Sennheisers are plugged, so don’t use this as a noise floor comparison but more to compare stereo image and overall mic tones.
Here are the recordings for comparison:
rain on roof – 8040 ORTF
rain on roof – LOM Usi AB
quiet night – 8040 ORTF
quiet night – LOM Usi AB
no denoise applied here, I think the “weird” sound is due to the distance (approx. 1km) and sound diffraction through the valley
distant motorcycle – 8040 ORTF
distant motorcycle – LOM Usi AB
wind in tree in the background
diffuse car pass by – 8040 ORTF
diffuse car pass by – LOM Usi AB
