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:

no denoise applied here, I think the “weird” sound is due to the distance (approx. 1km) and sound diffraction through the valley

    Thanks for this comparison. I own the Clippy EM172 which use the same capsules as the Lom Usi so I was really interested in this comparison. The self-noise on the Usi is definitely higher, but only noticeable in certain very quiet scenarios. I downloaded your recordings which were really useful for helping me tweak my noise reduction settings. I managed to get them sounding very close in terms of self-noise, with minimal elimination of the signal. What helps is that the Usi are naturally quite sensitive in the 7-10khz range which is also where most of the self noise is apparent. So doing some reduction in that range doesn’t hurt the signal too much.

      Thank you very much Doug ! I never tried the Clippy Mics but I’m thinking about grabbing a pair of EM272.
      True about the upper range, sometimes the Usi sound a little harsh so they can deal with a bit of noise/hiss reduction.

    Thanks for letting us see this comparison, one thing, have you ever used the mkh mics as a LCR and then the 2s LOMs for the back? As a 5.0 setup, not sure it will work but interesting to know if you have tried it!

    thanks

      Hi Björn !

      Thanks for your comment. Yeah I’ve tried that in the past, it worked okay but I prefer to use another ORTF pair as a rear pair alongside the LCR.
