MS setup (Mid-Side recording)

After spending whole day testing NTG3 with few other mics (like NT45, NT55 and ME66) in MS setup I got a conclusion: Rode NTG3 have similar output level as Sennheiser ME66. They also have almost same "hyper" cardioid pattern. Surprise NTG3 have more self noise than ME66. Most of the NTG3 noise was at high frequency level, even up to 45Khz, while ME66 noise was at lower frequency, sometimes mixed somewhere within the harsh midrange sound. BUT NTG3 sounds better than ME66. Softer sound with deeper natural low frequecy. Something above 6Khz was crystal clear and detailed compare with ME66. Something in the upper mid range in ME66 was also clear and transparent so it is not so bad at all.  
The other mics, NT55 and NT45 sounds cheap compare to NTG3 and ME66. No bass and low output level let this mics sounds like a cheap toy. But because of low self noise, NT45 and NT55 are remarkable better choice for quiet recordings than NTG3 and ME66.

It is important to fit all capsule on both mics as close to gather as possible. 
Therefor is it good to know the capsule placement in the mics.
The capsule on NTG3 is about 3,5" from the front end.
Photo: Strong but "soft" plastic plate holds the heavy NT2a Mic in place and decrease vibration between Blimp and the mic.
Photo: Elastic band cut out of bicycle inner tubes hold both mics in right position and decrease vibration to mics body.
Photo: Elastic band around NT-2a below the capsule will safe the mics body surface from scratches and decrease vibration.

Photo: The Sennheiser capsule can be what ever as ME62, ME64 or ME66.
Photo: Because of the heavy load of NT2a mic it can not be fitted with suspension. Here is a home made aluminium plate to fit the mic surely in a right place.
Photo: The mid-side mic is light and can be easily fit with suspansion.
Photo: The only problem with this setup is the heavy load of the Rode mic and the distance between the side- and midside capslules. 
There is also a high output difference between this two mics. (Rode 16mV/Pa and Sennheiser 31-50mV/Pa). 
Hi quality preamps must be used.

Photo: It can be interesting to use quiet mic like Rode NTG3 in this setup.

SE4400a mid-mic sounds best if it was selected as a omni (not carioid)
