One of the things I like most about the Infocomm show is that I always unexpectedly run into friends, and also invariably see something new. In 2009, that something new was Audio-Video Bridging (AVB), an IEEE open standard for transmitting time-synchronized audio and video over Ethernet, using special network switches. I've long been a supporter of open standards, and I was a big supporter of AVB. But after the 2013 AES convention, four years after that very public roll out, it seemed to me that AVB had been too slow out of the gate, and that Audinate's proprietary Dante audio networking technology had already won dominance in the live sound market (and I wrote about all that in a blog entry, which, amazingly to me, has had nearly 5,000 views). Everything I saw at this year's Infocomm further supports that conclusion.
These pictures (sorry for the cameraphone quality, I wasn't lugging my heavy DSLR around the show) sum up the situation for me. Here's the display by the AVNU Alliance (the AVB Trade association--I wrote a lot about them here after a visit to their testing lab last summer):
There's actually less on display this year than last year. There was the (very nice) AVB-based Avid S3L console, some interfaces, and switches from Extreme Networks, who, as of now, are the only company to get AVNU-certified switches onto the market. The Extreme switches seem very nice, but when I priced them recently I was surprised to learn that the AVB option costs over $300+ extra per switch. With so little AVB product available for our industry, what does that $300 get me? (BTW, recently there was a very cool "Brick and Bullet" AVB I/O Kickstarter that unfortunately did not reach its funding goal--they are vowing to go forward anyway).
Contrast that to the demo area at Audinate's A/V Networking World (AVNW) the day before Infocomm:
Here, there was lots of stuff from popular pro audio manufacturers that you can buy today, all connected together using standard switches and patched with a consistent interface. And in this all-day Dante love fest, they showed real world, completed installations, and lots of new, working stuff. My friend Jamie Anderson from Rational Acoustics presented on a recent SMAART class he taught where he replaced his old analog signal distribution system with Dante, saying it saved him several hours on the class because it "just worked":'
Another old friend, Michael Cusick from SAVI, explained the massive Dante network his company recently installed in a big renovation at the Planet Hollywood showroom in Vegas.
I had to miss the afternoon presentations. But Dante had a booth on the floor showing many of their OEM partners:
The booth also featured Audio Technica's ATND971, "the first wired microphone that transmits audio and control data together over the Dante network protocol":
So, it seems the prediction I made after peering into my crystal ball back in November still holds up: "... Audinate's Dante has won the race, while AVB is still being tweaked by the mechanics over in the pit lane."
Update June 24, 1pm: Here's a video from Audinate from Infocomm explaining the above and some things I missed at the show:
There are as many opinions about microphones as there are sound engineers. Experimentation with mics is a great thing to do, but what if you’re just starting out, or you need to mic something you haven’t worked with before?
For my students (and anyone else interested), I thought it would be fun to develop a list of “classic” live mics for live sound. Rather than just make a list based on my own opinions, I figured I’d crowd source it by creating a survey and sending it out to as many people as possible (and writing this, with the analysis complete, I just realized I forgot to vote in my own survey!). I ran a beta test of it with a few people on the always excellent Theatre Sound Mailing List, and then tweaked up the survey and posted it both there and on the ProSoundWeb Live Audio Board forum. 36 people completed the survey, which ended up being a bit tedious (it turns out we mic a LOT of different things!).
I asked respondents for two variations on “Classic”. The first would be “Money Is No Object”, and the second is “Most Commonly Used”. Here’s the list of the most popular in each categories (I've also got a better formatted PDF available here). Ties are indicated by multiple mics separated by “/”, such as SM58/AKG 414.

Respondents were encouraged to skip mics they didn't use, so a few of the entries are blank (I guess not many people mic tuba sections). A few also had pretty small sample sizes and ended up being less relevant--you can download my summary sheet of the top three results in Excel format here. I also have all the raw data available here (scrubbed of any personal information).
In general, the “Money Is No Object” section drew a lot of diverse responses, while the “most commonly used” tended to hone in on a few favorites, some overwhelmingly (again, see the percentages on my summary sheet linked above). Despite my efforts, I still missed some mics in my list, most notably the Shure BETA 91 for inside a kick drum (the eventual winner), and the write in box worked to correct that. The only other write in that I saw with more than a few entries was a couple Heil mics, but the respondents weren't always clear about where they should go, and the quantities would have only added up to compete for third place or so, so they didn't affect the categories where they were written in (some people also wrote in mics that were on the list).
This is of course not a scientifically accurate survey, since I have no idea how many sound engineers there are in the world, and therefore also have no idea how well this small sample represents the market. But I do think the list has some value, since it’s as if I had asked 36 of my closest sound engineer friends their opinion. And it’s an experienced group, with 82.4% of respondents indicating that they had worked in the live sound business more than 10 years. 90% said they worked at least partly in concert sound, and 50% do this kind of work primarily (I forgot worship sound in my poll so several people wrote that in). 24 (67%) of the respondents were from the US, but I also got seven from the UK, three from Canada, one from Germany, and one from the Netherlands. You can see the rest of the demographic result details in the excel sheet linked above. Thanks to all the participants! And, congratulations to Tim Perry of Utica, NY, who won the copy of my book.
It turns out that Survey Monkey offers a very limited set of options for data analysis for the “Matrix of Questions” type that I used, so I ended up having to do an unbelievable amount of spreadsheet magic to get the results. For that reason, I’m sure there’s mistakes in the list; if you find any please let me know and I’ll correct it.
NOTE: Survey closed, results posted here.
I believe that microphones are something everyone should experiment with to get the best sound for the application, but my students and others new to the business lack experience and are often looking for good starting points for professional technique.
So, for fun, I'm looking to develop two crowd-sourced "classic" mic lists, using two definitions of classic:
1. of the first or highest quality, class, or rank: "a classic piece of work."
2. serving as a standard, model, or guide: "the classic method of teaching arithmetic."
List 1 will be what your mic choice would be for a particular application if money were no object; list 2 will be what you use (or see used) most commonly.
I will publish the results here in conjunction with the upcoming 2014 USITT convention. All data from the survey (except for optionally given email addresses and names) will be available to anyone interested for download. And, I will randomly select one survey responder and give them a copy of my book, Show Networks and Control Systems.
If you use microphones for live shows, please take a few minutes to fill out my survey here.
The survey will close at noon NYC time on Saturday, March 22, 2014.
I've written before about controlling a GrandMA2 console, Figure 53's QLab V3, Weigl's ProCommander, and Stage Research's SFX all using ASCII commands over IP. I had a little time today (we're on winter break and don't have classes) so we set up our ETC Ion lighting console to see how to control it over the network. I'm a noob on the Ion, but I worked with my colleague Sue Brandt who can find her way around the board, and this blog assumes you know the basics of the console as well.
In most of the stuff I'm doing these days, I'm trying to move away from legacy protocols like MIDI, serial, and DMX and into IP everything. (Although, implementing my "simpler is always better" design principle, for an upcoming show we will be firing old school, hardware-based MIDI Show Control out of the Ion to control Dataton Watchout).
ETC has implemented into the Ion (and the Eos family) a simple ASCII-based "String Interface" control protocol that can be sent via a serial port or via IP. The commands are detailed on page 23 of the EOS Family Show Control User Guide.
Here's a couple typical cue messages:
• Go 1 – fire playback 1
• Cue 1 2 – run cue 2 from list 1, on the appropriate fader
• Cue 1 – fire pending cue from list 2
The manual is very clear that, "All text will be queued up until either a carriage return (hex 0D), a “\r”, or a “#”, is encountered to show the end of the command".
There's just a couple things you need to need to establish communications. Of course, the computer/device you are using for control must have an IP address in the subnet of the console. Our console had a Class A, non-routeable IP address. You can get to this screen by going to the "Shell" and selecting "Settings" to bring up the EOS Configuration Utility ("ECU" in ETC Parlance).
While you're in this configuration screen, you also have to turn on the "UDP Strings" feature to get it to accept the string commands (I learned this the hard way by not turning it on at first and finding a port rejected command in Wireshark; you can learn from my mistake):
(Sorry about the crappy camera phone pictures--if you want to see my better (unrelated) photography go to my Facebook page).
Go back into the main console software, and there under the Show Settings page you need to enable "String RX" (RX means Receive), and then pick some port for the board to receive on. I picked 56789 for this test (just make sure to pick something not on the assigned list).
That's the extent of the configuration on the Ion side.
For a basic test, I used the Essential Net Tools utility running on a PC. Essential Net Tools has a "Raw Socket" mode that is great for this kind of testing (socket just means IP address and port number combination).
Here's the ETC syntax to fire a Cue on List 1, Cue 5.5 out from Essential Net Tools:
That was it, that's all it took! Once configured, it worked just fine and was very responsive.
I then decided to fire the ETC Console from the Dataton Watchout multidisplay software system. To send ASCII commands out over the network from Watchout, you first setup a String Output (screen capture from the manual since I forgot to capture my screen).
With that in place, writing a cue was a simple matter of filling in a box and dragging it onto the Watchout timeline (as indicated, the $0D indicates a Carriage Return ASCII symbol:)
And that was it, it worked great! I've been doing this a while, but for me I find controlling anything over a network like this to be the most straightforward and powerful method.
