  1. Hey Alexandre. Nice idea to use this handy little stuff. I tend to half clumsily set my angles by vaguely judging something that “seems ok”, so this will bring a bit of balance to the damn thing.
    I see you’re sporting the friendly line audios, and was wondering about which coupling bar/suspensions/blimp you use ?
    How light and comfy would your set be ? I’m considering a lighter ortf setup and this doesn’t look too bulky !

  2. Hope the protractor helps! I created it in order to eliminate any phasing issues. The suspension is by Rycote called the InVision INV-7HG MKIII Stereo Pair Kit. You’ll need some kind of bar handle to screw into it. I’m still experimenting to have an even more stealth / compact kit. Let me know how it works out for you!

  3. thanks for the answer !
    Myself I’m sporting 2xSchoeps with MK4s, both independantly babyballgagged, on two INV-7, the whole thing screwed to a very crummy K&M bar. I bought the INV-7 separately without knowledge of the suspension-bar bundle… I’m kicking myself a bit about that.
    While I’m very happy with the sound, month after month I find my setup really too bulky and heavy…
    I’m tempted to try the Lineaudio someday, I wonder if they would fit in one of those new fancy Rycote ORTF blimp ? They don’t look too big and seem really handy !

  4. Great set up, where can I find your sounds? Not 100% sure if the CM3’s would fit, they are pretty small though so I assume if it’s ORTF you should be good 🙂

  5. Cm3s… New mics… Yum !
