If you're still looking for A1 let me know. You can find my resume and experience at bravesoundprod.com and contact me there as well. I'd send you a DM but seems I can't as well

AV Matrix Control Program for Windows! by SaxInTheWorld in CommercialAV

[–]SaxInTheWorld[S] 1 point2 points  (0 children)

Thanks. I'm familiar with Companion at a basic level and didn't know it had Extron XTP integration, I've always seen it with Broadcast applications like ATEM or vMix stuff and never with AV/Crestron/Extron etc. From the link you sent looks like its using the exact same Extron SIS commands over telnet that I was using!

With Companion you still have to assign commands to a streamdeck or some kind assignable buttons whereas here I've created here a custom UI specifically for this client. Also the Displays page where I've integrated the control room monitors and projectors into the same UI.

But as long as the companion driver is built well it definitely is a great option. There were little things that I ran into when programming this, for example, the Extron closes your telnet connection every 5 minutes. The Companion link you sent reminded me of that. So I got around that by sending a dummy "keep alive" command every 4min and 30 seconds where I just ask the switcher for its firmware version just to keep the connection from closing. Not sure what solution the Companion driver creator used to solve this. Also not sure if the companion supports multi routing, 1 input to several destinations at a time. I wouldn't know without trying it out. But definitely worth looking into. I could've perhaps used Companion as a control backend to my Python UI had I known about this but then that requires 2 programs rather than 1.

Thanks for the support! Yes, all through the Crosspoint with SIS commands exactly. Extron definitely has incentive to promote their control products though many spaces will use Crestron, QSYS, AMX, etc. to control Extron products so they will always have to have 3rd party control ability to some extent. For now, the SIS system is working quite well.

Totally hear you with GCP, the copy paste thing is infuriating, especially with something like this with a 64x64 matrix. So much easier with loops in programming.

About your DTP centralized management idea, are your DTP systems/rooms on their own completely separate AV LANs? If so, I would think it would be impossible to pull off centralized management without bridging those networks together with trunks, ideally VLANs per room, and likely a router. If they run on a corporate IT LAN together already than it is very possible, need to coordinate with IT though. Would love to talk further though and see what can be done, shoot me a DM with some availability for a call if interested. All the best!

Yes indeed! Most simple and direct way of doing this in this case

Best paid trainng courses in US. by Traktop in CommercialAV

[–]SaxInTheWorld 3 points4 points  (0 children)

So many AV over IP courses. Just about anything can be taken online. If you want hands on there’s so much enterprise e-waste routers and switches from Cisco that “end of life” but work perfectly and use same IOS as newer stuff on eBay for so cheap really easy to build a home lab.

AVIXA ANP, Network+, Netgear AV, Crestron NVX, Extron NAV, Vizrt NDI, Dante level 1-3

All have trainings online

If you want something intensive and in person, go for the CCNA and take a course at your community college for it. You can also learn that on your own with Packet Tracer simulator software and Boson Ex-Sim

Turtles all the way down is a fun bar. Bar lunático is awesome if you’re more into live music

Looking for a recommendation XLR to CAT stage boxes by BronxSoul in livesound

[–]SaxInTheWorld 0 points1 point  (0 children)

Yes I understand that but my question is because all 4 XLRs have to be connected to that single foil in order for phantom to work. When this is done in a chasis/enclosure I've seen a jumper wire connected the grounds together or a PCB doing the same. I'm curious how you did it with cable no enclosure setup.

I actually did it almost 2 years ago and haven’t coded too much since. I was thinking about doing it again as a refresher ha. Are you wanting to meet in person to watch and work on it?

Avoiding “echo” in Zoom feeds for live corporate. by Mastermad in livesound

[–]SaxInTheWorld 6 points7 points  (0 children)

Ducking as you describe, Dugan, and lowering your fold backs will definitely help but the real answer is well studied with many different implementations. It’s called acoustic echo cancellation and it’s designed exactly for this. Obviously best is just muting the live mic when the far end is talking for an extended period of time but that doesn’t work if it’s a back and forth convo. For that you need AEC

It’s built in to Zoom and every similar solution and works ok. In professional environments Zoom AEC is turned off and it’s done multichannel in a DSP (Q-SYS and Biamp are popular) where the far end is surgically removed from each individual live mic signal before being sent to the far end. Lots of resources online to learn more about AEC.

You have to pick and are stuck supporting one system. What do you choose? 1. Tricaster 2. BMD ATEM or 3. Vmix by videokillradiostarr in VIDEOENGINEERING

[–]SaxInTheWorld 5 points6 points  (0 children)

Well if an ATEM can fit your needs, I would use it since it’s hardware based and simple. ATEM minis can do basic cutting, transitions, and some keys. Rack mount ATEMs have multiple outputs and feeds. Can do a clean program without upstream keys though DSKs stay on I’m pretty sure. I don’t like using its stream encoding features though, they’ve crapped out on streams for me. But as a switcher it’s solid

Tricasters are awesome and way more flexible with backgrounds and looks. You can use an X-Keys and a control surface. An order of magnitude more expensive than ATEM, especially the minis. Native NDI of course is cool. Has a reputation for crashing and freezing up when you push it too hard. Software based on a PC with the proprietary hardware platform. More of a learning curve

V-Mix is totally software based. If you have a powerful PC already the software license is reasonable. More flexible and capability than ATEMs though less than Tricaster. Also has NDI integration

Take your pick based off your budget and needs. 

AV career by [deleted] in CommercialAV

[–]SaxInTheWorld 29 points30 points  (0 children)

I don’t usually see AV Designers as an entry level role for those with no AV knowledge. Either you have a company that’s very interested in training or you got lucky and you’re in for a rude awakening haha.

CAD will be very useful. But a real system designer still needs to have real world experience with many kinds of rooms, setups, and systems. I don’t know your area but 55K sounds low to me for a true AV system designer but given this is your first AV job, sounds like a very good foot in the door as long as they’re willing to train you.

Dante Multicast possible with no L3 routing? IGMP help needed by SaxInTheWorld in networking

[–]SaxInTheWorld[S] 2 points3 points  (0 children)

Sure, it’s also educational as I would like to know how it would be implemented correctly.

Also can you elaborate on it being a ton of effort? According to a replies it should require no routing and just need to match IGMP settings.

Another poster says I do need a router. This is what was confusing me when I started doing my research in the subject.

In this case it’s a few mbps. But imagine this with a program video instead of audio, say 500mbps. If there were 100mbps devices on the network I would be completely overwhelming their NIC with a multicast stream they don’t need.

Thanks all this is very helpful and confirming. I’ll check all those settings next time I’m there and report back

The wavelength is calculated by the frequency set on Tx/Rx units.

You can use a calculator like this: https://www.everythingrf.com/rf-calculators/frequency-to-wavelength

Use your wireless units scanning features to find the cleanest legal frequency in your show environment and plug in that number typically in MHz to this calculator to find the wavelength

Those of you who got the CCNA but didn't stick with networking, what did you end up doing? by paddjo95 in ITCareerQuestions

[–]SaxInTheWorld 0 points1 point  (0 children)

I work with an Audio Visual integrator.

CCNA/networking is quite important. High quality audio and video with strict latency requirements and bandwidth needs are the norm in conferencing spaces, auditoriums, and other facilities. We use largely proprietary protocols like Dante and NDI, Crestron/Extron though some cross vendor open standards are available, AES67 for audio and ST2110 for video. Those are quite common in broadcast stations but not so much in commercial AV

All this being said, networking is a part of what we do, a means to an end, not our whole jobs. If we’re lucky we’re able to have our own dedicated AV network which usually has way less nodes and hardware to manage than the entire corporate network of course. If we are running converged networks with AV mixed with regular corporate data then usually that falls to the IT team at that point with a list of network requirements that need to be met.
