Something I‘ve been waiting for for a long time. With the CMC 1 this will be a pretty compact unit, probably like the MiniCMIT, but far more flexible. I just don’t understand why they don’t demo this with a blue preamp (which they do make) or a grey KMIT. This grey on blue looks ghastly

Wow, the specs really do look very good! Only weight and size are letting it down somewhat. I am a big fan of the 4017c, mostly for its pickup pattern, so I‘d be very curious to try the 2017, which could be a very good backup mic. Also, I am having trouble with one 4017 with rf interference, so this could be interesting.

Schoeps themselves sell these little plastic screw top tubes for their capsules. I use these all the time for Schoeps. They have them in different sizes, but nothing long enough to fit a interference tube, afaik. As you probably know, it’s best practice to keep capsules on preamps at all times, but if that doesn’t work, those tubes are ideal. They also sell these tubes that can be untwisted in the middle (sorry, finding it really difficult to describe in English) and are large enough for shotgun mics. Similar to what Rycote sold a few years ago with their mic storage solution that I forgot the name of. The Schoeps solutions are probably only suitable for mics and capsules with a slightly larger circumference, so DPA mics at 19mm won’t really fit

Schoeps do specifically advertise their mics (most of them) to work with 12V. Interestingly, you can power the MiniCMIT with 12V, but you can’t power the CMIT with 12V. However, they do state that the dynamic range is reduced when using only 12V, top spl is only 115dB as opposed to 130dBspl when powering it with 48V. This is not wrong on its own, but in this context perhaps a bit misleading. Many small diaphragm mics need 48V as well, such as the regular CMIT. Then there’s the MiniCMIT another small diaphragm mic, which is somewhat fine with 22V. On the other hand the DPA 4017, also a small diaphragm mic, is actually an electret mic, but it too requires 48V

It‘s classic clickbait

I‘m not sure if Google really did nail it. With regards to audio waves it seems correct, but antennas can be vertically polarised or horizontally polarised. That shouldn’t really affect phase as the moment in time a signal radiates from an antenna would still be the same, but with horizontal polarisation the rf wave sort of lays on its side, whereas with vertical polarisation its upright. I‘m just curious how it could change from one to the other, but I don’t want to take this thread too far from its original question, so maybe I have to find this info elsewhere

Hence my page for Larry, if anyone knows it’s him. I just can’t imagine how the wave would change orientation mid-air. I guess if it hit a parabolic dish or something it could happen. in space on the other hand, maybe it rotates all the time, who knows, that is certainly easier to imagine for me

I always thought this was polarisation not phase, but in any case I was always curious about this. Some wireless manufacturers used to sell their receivers with one antenna sideways and the other straight up. It’s rare that I would have a transmitter sideways, but it does happen and it’s good to have a sideways antenna ready for that. However, I don’t understand how a rf wave can change its orientation once it’s gone from the transmitter. So I can’t see an advantage in having both at the same time, but like I said, just because I don’t understand it, doesn’t mean it won’t happen. phase diversity as I know it is how Lectro receivers work(ed) for a long time. But at this point we probably need @LarryF in this room

Yes, that’s what the A is for. 😉 log-periodic dipole array

Just to pick this up before a develops a life of its own: sharkfins are dipoles. It‘s in their actual name, LPDA where the D is for dipole. a dipole can be made to be either omni-directional or directional. The classic whip antenna is a monopole and it is omni-directional, as is Betso‘s Bow-tie, for example, which is, well, a bow-tie antenna, but it’s also a dipole. It certainly is worth a try. I did try it a few times, but I have not been able to produce significant improvements over two sharkfins, but that was only in that given situation and I never made any real comparisons. What you are saying about the reflected signal possibly reaching the antenna from the side rather than straight on, does appear to make sense.

Really? This is the first time? I‘m surprised! I think I actually wanted to write: „omni antennas wil not mitigate this, BUT they don’t have the …“ Anyway. Yes maybe the omni can work well, too. I suppose they may well worl better indoors and sharks probably perform better in more rf congested areas. But while I don’t have any measurements or other proof ready to strengthen my theory, to me it always seemed like when I am really far away from the transmitter, my sharkfins could still receive a signal (when they were pointing in the right direction), when omnis were already crapping out. but, YMMV. I‘m fine with that

I think there is no rule to this. Whip antennas as found on the transmitters radiate in an omni pattern, but the body they are attached to will block a lot of signal in that direction. If that is where your antennas are you’d lose a bit of signal strength, it would make sense to have another diversity pair on the opposite side of the set. But it kind of depends on how your actors are moving around. Ideally, you should have antennas there where the signal isn’t obstructed by the actor‘s body. I would say this could be achieved with a single pair as well. I did try this once and it worked really well to extend the coverage area. But with two pairs you‘re definitely better off Using omni antennas on your receiving end will not mitigate this and they also don’t have the signal boost quality that comes with the shark fin design

Just remember that maybe two years ago, AI was a thing mostly for nerds. Along came ChatGPT and suddenly there’s AI everywhere. We have generative AI (music, pictures, movies, speeach) that was unthinkable just a very few years ago. It has come along so fast. And that is kind of the AI thing: it will learn and improve itself, that will be a very exponential curve. so a lot of that happened in the last 2 years. Imagine what can happen in the next five…

Actually their spitters work bth ways. So they can either split a signal or combine the two ports (or more) into one

I actually find the 48V capable plug-on quite useful. You can decide if you currently need it, for a handheld mic, but even when I had already upgraded my wireless, this was still useful as a bonus 2nd boom or as a plant transmitter. Plus, you only need to buy a single receiver to have a second channel, like transmitting to a camera or whatever
