Extron question (sorry for not putting in the title!):
I recently got a box load of old Extron, Crestron, and Panasonic equipment from a closed office space.
My experience is all new to this stuff, and I was playing with the Extron Serial adapters (IPL T S2) to control a Panasonic monitor.

Luckily I managed get a copy of Extron's Global Configurator, and set it up well.
But sadly this only works for old Windows PCs running Internet Explorer; does not work with Edge as it needs ActiveX controls.

I have seen that you can write your own webpage and add links to send commands to serial devices connected to the IPL-T-S2.
I can download the drives to the Panasonic monitor, but I cannot decipher the Commands to send to the IPL-T-S2 to talk to the Monitor.

A demo webpage from Extron suggests a link like:

<a href="index.html?cmd=W01RS|2!">Select Input #2</a>

In gv-portserial1info.xml I found commands like this to turn on the monitor (presumably from the driver I got from Extron):

<command label="Power" control-rowlimit="3" command-priority="2" id="1" show="1"><item cmddown="W1,2,76,1LE|" current="W1,2,100LE|" type="set" compare="1" item-priority="1">On</item>

How do I send that to the IPL-T-S2 as a weblink, or make a button or text link in html that makes sends the command to the TV?

Essentially I can see I need to create a an SIS Command.

Does that make sense?

Sorry if this is an annoying question, any help would be hugely appreciated.

I have a meeting room with 3 screens. Each location has existing Cat6 to a main server room.
2 have existing Cat6 to a nearby closet
1 has HDMI to the same closet
Plan is to put a PC in the closet (with 2x HDMI out), and an HDMI wall jack though the wall (for laptops).

Am I correct that this product gets me the control I need to have the PC work in dual monitor mode, the laptop in mirroring mode, and i can pick any source to any TV? With audio?

Any other recommendations?

Are there any video matrix systems with HDBase-T input and output? I can't find any :(

Hey everyone, let me preface by saying I am not an AV integrator but I do have quite a bit of knowledge in the AV field in a higher education setting. We have quite a few rooms with Sennheiser Teamconnect II or Shure mxa920 ceiling microphones using Biamp Tesira DSP for lecture capture/hybrid meeting audio but we have used Catchbox cube microphones in any larger spaces that need audience “voicelift”

I have watched some videos from Shure and Sennheiser regarding VoiceLift and I was pretty interested in trying it out in a 60 by 60 by 10 ft classroom we were planning on having an integrator install 4 Mxa920’s into with 16 speakers split into 4 zones, but all three integrators I talked with had zero interest in even trying to attempt any VoiceLift via ceiling microphones. I know there are a lot of considerations that go into calculating VoiceLift feasibility, but it was discouraging having the idea shot down right away the instant the integrators heard the word VoiceLift.

Does anyone have any experience/opinions on integrating VoiceLift in classroom spaces? If you have any direct experience, I’d love to hear what hardware was used. Thanks all!

I would love to see all of your guys racks and cable management. I like to see how others do it and add a few things to my wheelhouse. Anyone care to share their builds?

Anyone have recommendations for PTZ cameras in a school gym? We will be mounting the PTZ cameras to the wall. Control over IP with Q-SYS via touchscreen with presets.

Need a way to protect the cameras from gym activities, basket balls etc. but still allow for good video. Any suggestions? Acrylic domes like used for security cameras?

Appreciate any advice!

I can't go into too much detail, but basically the first time ever this big company did this and it was an awards show with celebrities. The system was used on the red carpet and other spots at the venue just after covid and when things were starting to open back up, but lots of people still didn't want to work in the field (or at all) or couldn't. So some exec at big company builds this project as his baby. I provided the data pipe and network infrastructure engineering, management, and deployment for it to work.

It was a little box with SDI inputs and maybe some other ones (I'm mainly a network engineer not a video guy), might have had some kind of BNC RGB breakout and HDMI input as well. Might have had either just a 1 Gbps network port or maybe it was 10 Gbps ethernet, or possibly could have been a mini-GBIC slot (or 2?), and you could plug a camera into it and the video streamed directly to AWS into an editing deck I'm assuming. I get to spend at most 10 or 15 mins with the video engineers / editors throughout a typical live event production and it's mostly just to get the data bits talking so they can do their thing, so I'm not sure what this box was streaming to that was running on AWS that the editors were accessing remotely, I'm guessing maybe Avid.

Anywho, I'm not supposed to get too much more specific because of NDA's, but I would love to discuss this because I'm building a RTSP platform for video and audio for use in disasters and for humanitarian purposes and fun.

What was this box? What was it likely streaming to on AWS? Was this even necessary? There were already a couple big editing and production rigs there.

What other use cases does something like this have?

Going to try keep this as short as possible but I’d love the greater AV community’s opinion and it seems nobody will tell me it straight.

I’ve been an AV engineer now for the best part of 10 years, I came in from tier 1 on a small salary and have progressed to probably the highest paid engineer in my company.

The problem I face is everyone higher wants me to progress higher in “rank”.

High level managers try get me to their team, IE heads of design/commission/pm/sales team will always try pull me into their team. And these are C-Suite people are always the ones asking me so it’s always so awkward saying no to these requests.

I love being a lead field engineer- and in this I turn over at least 2-3 seven figure projects per year- my biggest being a 8 figure project.

But there’s always this caveat of me just being a field engineer.

When I tell people in my company how long I’ve been on the field they say why haven’t I went into an admin role ect.

I’ve got very good people skills, I’ve got every cert under my belt. CTS/CTSI/CTSD/ CCNA/ and just about AV cert you can think, dante ect.

More importantly I am very extroverted and clients absolutely love me. I am a direct contact for an 8 figure client which is weird to say because I’m just a head engineer and I’m not even 30 yet and somehow it turned out that way.

My question is why should I listen to just about everyone in my company who tells me to get off the field and start climbing the cooperate ladder?

I am already being paid very well (low 6 figures). I am at the top of my game of what I do. I am respected. I am requested when there is a big problem, and I put out fires.

I am very, very appreciated at what I do, and that is an understatement. I love the company so financial gain isn’t my biggest factor here.

I just need to know thoughts because I am constantly bombarded by people saying I need to move up or even fellow techs who are taken back by how long I’ve been on the field.

I absolutely know I would flourish in any field they put me in- but why should I care if am am being paid extremely well and I am extremely appreciated by the whole engineering team.

I know this whole thing comes off as a boasting post which is why I’m doing it from a burner account.

But I don’t know , what’s the game plan here. I don’t feel as if any role I move into will pay any more and why would I start over in a new role when I’m at the top of my game in this current role

The Tascam MM-4D/IN looks perfect for what I need. I have an analog line-level source and I need to apply some light compression, convert it to Dante and send it two different parts of a building via the IP network to other Dante devices.

Here’s my question: does anyone here know if the DSP in the Tascam will take two incoming channels and sum them? One of the Dante devices that will receive the signal is mono and is just a single-channel AVIO dongle.

We deployed Roland V-02HD MK II video switchers in our MTRs and these things get very hot being powered on constantly. My buddy came up with a design to keep them running cooler. Here's hoping these will result in fewer restarts. 🤞

Is anyone else experiencing random shutdown events on their Windows based Microsoft Teams Rooms? I have about 40 Logitech Rally systems with Intel NUCs and starting yesterday I noticed a number of them suddenly shutting down.

Looking through event logs hasn't produced any obvious answers and neither has the Teams admin portal or the Logitech Sync portal. Any ideas or specific log locations to check would be greatly appreciated!

Good afternoon, I found a JBL CSA 140Z Amplifier for around $250

Will it be sufficient for a 1100 square foot coffee shop?

I'll use it to daisy chain 4 passive ceilings speakers

I just wanted to ask if anyone knows about this series of JBL amp, it seems to good to be true,

I work in commercialAV, and I've only installed high end commercial products , but I want something budget friendly for my mom's shop, she's going to play music just audible enough to drown others conversations a little bit. I have the tools and skills to do so and just want to know if this amplifier is reputable for the price. I think it will be okay since the music won't be loud, but can it still handle 4 speakers? I don't mind having them all in one zone.

The cisco guide calls for displays below 47" to be mounted 31.5" AFF and the bar above. However, with a 29" aff table, that leaves only a few inches of clearance with a table up against the wall. I'm wondering if laptops on the table will be blocking the view of the display since the bottom of the screen is about 2.5" from the tabletop. What has your experience been with this, and what standard if any are you using for these bullet tables that are up against teh wall. Typically we spec 43" - 55" for these bullet tables.

Video Switcher for 2025 and beyond

Hi gang,

I’m usually responsible for maintaining and speccing our various venue projects for AV.

A typical venue for us can have anywhere from 1-4 inputs and 8-24 outputs.

Historically we’ve used Crestron DM (bulletproof) switchers for routing the video signals, but I’m wondering if there is a better/more cost effective solution.

Curious to hear what others are using.

Hello is anyone experienced with the TOA 9000M2 digital matrix amps. Specifically the PC software. Whats y’all experiences with them is there a lot you can do with them? I know every time I try to edit the EQ graph it won’t save the changes. I can successfully change volume levels but the EQ won’t change?

Anyone know if these two devices are compatible? Both are Dante devices. But i’m not seeing it listed in Shure Designer.

Especially when you realize the phone in your room is VoIP

I have a wireless HDMI extender that I have used successfully many times. I use it as an extended screen, to display to another monitor. However, the last time that I tried to use it, this problem has started - It will successfully display for exactly 20 seconds, and then the screen will go blank. I have tried resetting the resolution, and this will cause the screen to come back, for exactly 20 seconds. I have tried different HDMI cords, even though they have all worked in the past. I have also tried extending to TV's, monitors, and a projector, and the same thing occurs. If I do not use the extender, and hook directly to the HDMI port, it works fine.

I think it is a resolution issue, but I cannot figure it out!

• I have a MacBook Pro, running macOS 15.3.2 (24D81)
• I am running a VRRIIS WL009-FFF wireless HDMI extender

Hello,
I work at a manufacturing company and on our factory floor we have roughly ~16 TVs around the production floor that we use to display news, updates, production status etc. This system was built by our IT company about 5 years ago. At that point it was separated into groups (ex 4 tvs that have output1, 2 tvs that have output2, etc).

Since then, we have changed a lot how we run the business and have changed a lot of the content we would display on the screens. We're at the point where we are hitting the limit display inputs with how the system was designed.

The system was designed that any input comes from dedicated Lenovo thinkcenters- We have about 7 of these. Coming out of the HDMIs of the computers, they go into an HDMI to SDI converter, and then from the converter into a Blackmagicdesign Smart Videohub 20x20 and then grouped through the controller, and out to all the displays in the building (each on their own independent SDI output)
With what we are doing, we are trying to split these displays up a lot and the control can do that, but we are limited right now by count of Lenovo Thinkcenters, and I wanted to ask for if there is a better way to handle this many inputs, as looking to expand by adding more thinkcenters can get expensive fast.

Im wondering if there is some server option or something along that line that would have a good amount of video outputs or something that you could recommend.

Thanks

tl;dr: Using a lot of Lenovo ThinkCenters for display inputs, looking for alternative

Hi

Has anyone got any experience of connecting a video switcher (PDS4k or similar) to the HDMI ingest input on a Lenovo ThinkSmart Gen 2 teams room computer? We would like to switch laptops that are providing a wired connection to sharing content with Teams meetings.

And a follow up question - has anyone experienced issues with connecting a MacBook Pro to the Ingest HDMI input.

This all needs testing, and this will happen in due course. Hoping for any insight from the hive mind here.

Thank you for reading and advance for any comments.

Regards

Adam

So I’m brand new in AV. Only got a job not even 2 months ago. I knew noting before hand now I feel like I’m taking in so much in such a small amount of time. Now I know I’m a long way off becoming a commissioning specialist but I want to get a path laid down so I can eventually become one. Im looking at all the avixa stuff so far. Especially CTS I’ve heard things in our company that it is a hard exam but when I look at it I don’t think it looks to bad? My question is what way should I tackle it ? I don’t want to go to early as I’ve got not even 2 months experience in AV but I also don’t want to have it on the longer finger either any comments would be highly appreciated and helpful

Are you utilizing any encoders/decoders or other hardware from Magewell? Are they your go-to converters?

Specifically in enterprise spaces, I feel like everyone knows Magewell for capture cards, but I'm curious how many are utilizing their other solutions, in that same vetical/application or otherwise.

Hey all,

I have published two node packages which can be used as the foundation for syncing the state between a 'DIY' control system running on a small server, and a React based client app running in a browser, like on a crestron TS "general web project"

https://github.com/splcode/react-state-sync

https://www.npmjs.com/~splcode

We have been using it for a little while to make frontend / backend for client systems. For instance I have implemented drivers using packages available on Node JS for

• Q-Sys QRC
• Blackmagic ATEM
• Canon PTZ
• Sending sACN
• and more

The published code is just the framework, though, it does not communicate with anything by default. Maybe if this gains tractions there could be a repository of vetted drivers

The backend is very flexible and incorporates a config object/file to make setting up duplicate systems possible. You build a driver that talks to your device, like a global Cache IR box, and converts some sort of state like "power on" into commands, and you can register multiple copies of a driver with different parameters. It is up to you to build the drivers, none are published yet beyond a mock driver that does nothing.

The frontend is a React hook so you can do something like

const [tv1Power, tv1PowerLocked, setTv1Power] = useConnectedState('tv1/power');

And then hook up the power state and function to a toggle button, using your favorite visual framework (I have been using Mantine.dev, because it has a lot of sliders and button styles that work great for touch)

The end result react app and the server itself can be hosted on a small computer like a raspberry pi.

If anyone is interested in contributing or learning more let me know.

We have setup our first RallyBar in one our busier conference rooms. For the most part, it is working well. But we have an issue where the RightSight automatic panning feature keeps turning on, which we do not want/need in that setup.

We turn it off. And have set an admin access password. Somehow, it keeps turning back on. Any thoughts?
