    Nah they're going vintage. The 5 pin DIN connector is back!
  2. I got the Sachtler SN607 bag. An Anker USB-C battery fits on the bottom without problem and there's room for some cable management.

    Noise canceling headphones on set?

    Noise cancelling headphones cancel background noise reaching your head by phase cancellation by using microphones mounted on the cups. Of course it doesn't filter out any problems picked up by your microphones. So, clothing rustles, etc, will be heard actually better. While isolation headphones are better at removing high frequencies, noise cancellation excels with low frequencies. Phase matching for high frequencies is too critical, so it's not feasible. The advantage of cutting low frequency background noise is that our ears suffer from a masking effect from low frequency sounds. So, removing them can be really beneficial. In short: you will hear better what your microphones are actually picking up. Maybe some manufacturer has added some "intelligent" noise removal system? I don´t know if that's the case. I can say mine don't do that. I own a pair of Sennheiser PXC-550 and the sound is very good. Maybe not as "analytical" (ie, a bit overhyped in the high mids) as the MDR-7506 or the Ultrasone HFI-650, which are really good for monitoring, but I don't think they hide much. I have also a lighter pair by Sennheiser, I don't remember the model now. They are small over the ear ones with the typical "walkman style" form factor. Adequate for uncompromising situations but I wouldn't trust them for anything serious. They are a bit bassy and, moreover, given the small size they are prone to distortion (I think caused by some feedback between the speakers and the microphones) if the phase cancellation tries to cancel a strong bassy sound. For example, traveling by bus and hitting a bump. The PXC-550 doesn't suffer that problem. Moreover you have three different noise cancellation settings: 0, mid, high. Of course not all headphones are born equal. I tried a pair of Bose (I don't remember the model) and the result wasn't so good. Slightly better cancellation but a somewhat "boxy" sound. And if you want to punish someone, Beats are orders of magnitude worse than the worst torture device developed in the Middle Ages

    I bought NEUMANN KU100

    Inary is a lake in Finland, and the name of a friend’s daughter for example.
  5. I am sure all of us have heard of this on many places but it's worth having a notice posted here. In the last years there have been several high profile intrusions in popular (and important) Internet services. Adobe and Dropbox to mention two of them. The intruders got a huge database of usernames and passwords. The problem is, those usernames are often email addresses and most users reuse those passwords in other accounts. Which is very bad news for the user especially if the compromised password is used for the email account. I mean: Imagine your email address is justme@gmail.com. You registered on Adobe and you used the same password. That means that the guys who stole the passwords from Adobe may have the password of your email account. Maybe some of you have received a message from a place called https://haveibeenpwned.com warning abou the breach. The site I link is legit and you can check wether a username with your email address has been compromised. Note that, despite clueless news reports, your actual email account hasn´t been compromised unless you reused the same password. The site promotes 1Password, which is a very good password manager, but Mac OS X has a decent password manager built in as well. Now, the advice. First: Do not reuse passwords. Nowadays there are good password managers. Second: If you need to reuse passwords, make sure that each one of your important accounts have a unique (and good!) password. Which ones are the important ones? Any account linked to financial data, credit cards, software licenses, or, of course, email accounts. Email accounts can be used for password recovery in other sites, so email security is critical. Third: If you are reusing passwords begin changing them right now. Prioritize according to the previous recommendation. Email, banks, Amazon, eBay, Paypal, etc. You can also use the same website to check wether a password was found somewhere. It won't reveal the accounts to which it's linked, but it's a good way to know at least how unique the password is.

    I've often wondered about a Jecklin disk myself. Hope you can share some sound samples!

    Actually it's an interesting topic when discussed in a civil and rational way. In other areas not related to audio I've seen different cases of rebranded OEM hardware. In one of them, a marine aquarium filter sold under two different brands, there was a clear difference in product documentation. One of the brands included a thorough, well researched and well written manual while the other just had a placeholder. I could desribe one of them as a sheet, the other as a shit. Both units were identical as far as I know. (Note, I didn´t do sophisticated checks of important stuff such as the alloy of the pump shaft which can be an important difference for a marine aquarium). So, not all rebranded OEM products are born equal. - The Western brand selling them can offer a good technical support. You may even find out that comparing two brands selling the same unit one can give a superior technical support or offer superior warranty terms. That costs money (a lot!) and it certainly justiies higher prices. - The Western brand may have actually secured a supply/manufacture with higher grade components and/or some design changes. Only a thorough comparison would determine if that's the case. The outside look can be identical but, what about the inside? A good example would be the Sound Devices branded SD cards. Probably they not only have tested them thoroughly. If I were them I would have secured the supply with the OEM so that they don't make changes to the components or firmware without approval. And there are of course clueless brands beyond help. Several years ago I suffered a serious metal contamination incident in my aquarium with the sudden death of all my coral colonies. Before that they were growing a centimeter a month or so. Turns out the culprit was a poorly sealed magnet. To my horror, the vendor was unable to tell me the actual magnet composition. And they replied with nonsense when I asked why they hadn't sealed them with epoxy. So, not all brands relying on OEM suppliers are born equal.
  8. As far as I know they are not limiting it to Apple chargers, but they are picky with protocol details. So only power supplies supporting the power delivery standard will work.

    Ah yes, one of the old treasures of the BBC I purchased the dvds even. And the book by RV Jones is a terrific read.

    The Germans had radars as well. I highly recommend “The Most Secret War” by RV Jones. He describes some interesting differences between the German and British radar. Moreover, the main factor was how the British exploited the information obtained by them.
  11. I saw it and it's an exciting advance. That said I think it's a bit overblown to say that they have a commercially available quantum computer. After all they acknowledge that for now there's nothing you can do with it you can't do with a conventional one. I think the video was targetted mostly at investors in order to create some buzz. And yes, IBM is one of the very few companies that can eventually pull it off. Not many have Fundamental Physics research laboratories.
  12. Maybe that's why Apple are dragging their feet on the Mac Pro. They are planning a Maq Pro That said it's not the first time someone makes a questionable announcement of a quantum computer. D-Wave have done it several times.

    Sound Devices MixPre version 3.0 Now Released

    Playing devil's advocate here, it's a tricky issue. What if a user, no matter how much it violates the philosophy of a field recorder, uses the computer to set up the sample rate? I've seen weirder, trust me! Coming from a security background I find it much more convenient to prevent mishaps by restricting the functionality to what you need. The designers provide two different menu options in order to determine exactly what you want to do when you connect it to a computer. - You may want to use the computer only for power. In that case, file transfer is off and USB-C mode is "power only". - You want to transfer files? USB-C mode in "power only" and activating the file transfer. - You want to use it as an audio interface? Then set USB-C mode as "Audio". It will become a class compliant USB audio device. There is a good principle in software design, albeit sadly it's being forgotten nowadays: The Principle Of Least Astonishment. Having the recorder somewhat "decide" to switch sample rates is (in my opinion) a bad choice because it's a POLA violation. Moreover, it may cause a conflict with some use cases or, who knows, future features. Given that I make a living working on computer and network security I am going to give you some free advice. Never connect a USB device to a potentially untrusted USB port unless you are certain that the device will survive unexpected USB commands. As a silly example, maybe you are in the field, you connect your recorder to a friend's laptop with who knows what audio configuration settings and you are busted Maybe SD should rename the USB-C menu to "safe sex" to make it clearer!

    There is a setting to determine wether the USB port is used only for power or for audio as well. If you use it for audio it will obey a request from the computer to switch the sample rate. System->USB-C By default it’s set to “Audio”. Try setting it to “Power Only”. After you do that it won’t appear as an audio interface when connected to the computer.

    Odd anyway. Did someone forget a curly brace assuming they develop in C or C++?
