Decca tree stereo mic set-up with three omnis

[Haydarpasa]

Hello,
I am new to this forum and wanted to ask if it is possible to use two different brands when recording with three omnis in a stereo decca tree set-up?
I want to use two Sanken omnis for the sides and one spot Earthworks mic in the middle.
They all have a flat frequency response.

By the way does it make sense to record with a mic which goes all the way down to 3 hz amplified with a Millennia hv3c or an Earthworks zero latency pre-amp?

Thanks a lot for your support.
Regards,
Haydarpasa.

Welcome Haydarpasa -

This topic would probably be best served in our Acoustic Music forum as that's where all the live, orchestral recording guys/gals hang out.

In any case, yes, you should be able to use different brands with no problem. Granted, your best sound will come from three matched mics; however your setup should work.

When doing this, I've typically used my "darker" mics on the outer edges and the brighter mic for the center mic.

As for reaching down to 3Hz, I haven't heard too many that would go down there (haven't tried the Earthworks) but the Gefell M296s I use go down to DC and I do notice a few things with it that I don't with my Schoeps. If you do a gentle HPF below 30Hz, you'll gain back an additional 5dB of noise floor.

Cheers-
Jeremy

Well I like recording air conditioning noise so I think a response to 2 hertz is much more important than 3 hertz.

Did you here that harmonic come off that violin at 125kHz? It was sweet. I think I'm stuck to my seat?

Acetone. If it's on fire will the forest hear it clearly?
