Logitech Rally Camera

I'm using this camera as a webcam option as for a PC. I wanted to know if there's any software that could be used to control the camera (PTZ, Presets, all that jazz). Logitech sync only pans but it's basically for preview purposes.

MIDI out for QSYS Core? Or alternative controls for LS9

Have an LS9 as my main mixing board for an install. It feeds mix out to my QSYS core for system processing. I would like to add a UCI button to mute a channel on the LS9 but can’t find great resources on IP control of the console.

I read online most people use MIDI to control it. Instead of using a PC USB Midi interface triggered by QSYS is there any IP Native Midi interfaces! I’m thinking like a Global Tach IP2IR or something form factor must be out there.

Alternative options are to send split mix and recombine in the core or open Wireshark and sniff the Yamaha software.

EDIT: LS9 Edit uses Network Midi? Cool. Can this be tapped into by external software?

Streaming audio in a QSYS UCI

I’m wondering if there is an “easy” way to add an audio stream to a QSYS web UCI. The idea would be a user would select an audio channel from the core to subscribe to and the audio would be played in that webpage.

The goal would be to avoid adding hardware or software to the existing PCs. I realize this could be done with Dante or by connecting audio out channels from a QIO or core, etc, but looking for a purely web based option.

Small budget purchases for small church

Hey all,

I'm in charge of purchasing a computer and PTZ camera for a small church.

They currently have one camera set up directly across from the pastor on the other side of the sanctuary, about 70-ish feet away. They want the new camera to be PTZ so they can put it elsewhere and control it via NDI. Budget is $700. I've seen a lot of recommendations for PTZOptics, but then others say they're overhyped and to look at SMTAV.

They also want to replace an 8 year old Windows PC, preferably with a Mac. They're moving from PowerPoint to ProPresenter and Mac reportedly has better integration. Budget for this is $800. I'm currently looking at either a Mac Mini M4 or a Mini M2 Pro. Which of these would be best, or something else?

They'll have an Atem Mini Pro that everything plugs into, and a couple NDI converters for some TVs around the building.

Let me know what y'all recommend, or what other info I can provide. Thanks!

Conference room Setup help

Note: Boss wants a proper system for video call / screen sharing meetings, I am no it or anything, but I was chosen for this

Looking for a help/recommendations on a meeting room setup with camera/speaker/mic that allows for byod as people bring laptops and sharing screens. So far internet has steered me towards logitech meetup 2 but I am not sure.

The meeting room is medium sized, 10 people with a long rectangle table setup and an existing large screen tv, previously we would use a laptop in the middle of the table but they want to have an actual setup. It is a small office so there is no proper microsoft teams or zoom setup other than sending links to each other.

What would you guys recommend for a not so expensive setup, could be premade solutions like cisco/logitech or just diy with mics/cameras but I am not sure what to get / start

Dead USB ports on Logitech Teams NUCs with Rally PTZ cameras

I work in IT for a medium sized organization that has been installing a number of meeting room AV systems in the last year or so, which have been using Logitech Rally Teams bundles for virtual conferencing. I started getting trained to support these systems last summer to fill in for a colleague who was going on leave, so I'm still fairly new to their quirks.

Since mid-December we've had four different Rally cameras go down, and after extensive testing I've discovered dead USB-C/thunderbolt ports on the NUCs in three instances and dead USB-C/10gbps cables in two instances. I also learned that we went with third party USB-C to USB-C cables instead of Logitech branded strong USB-A to USB-C cables because Logitech cables were so expensive.

So the question is whether these NUCs have inherent USB port problems or the off-brand cables are running too hot and killing them, which so far I haven't been able to think of a reliable way to tell.

I'm wondering whether anyone here is aware of these Logitech NUCs being notorious for sudden USB port failure, and if so whether that's an issue that can be mitigated with driver or firmware updates. Logitech's documentation has proven unhelpful in answering that question.

Thanks in advance!

HDbaseT which doesn't send constant hot plugging signal on HDMi pin 19

Hi folks,

I'm looking for a HDbaseT sender which will still allow display auto switching to work. In order to achieve this, when the sender has nothing plugged into it the receiver shouldn't be sending any signal to the display. I'm told most tx/Rx will send a constant HDMI pin 19 signal which will force the display into thinking there is a constant source input.

Any recommendations on a product which doesn't do this?

70V/100V line system

Hi all, quick question, for a 70V or 100V system, can I run different tap settings on the same loop, or 30w, 30w and a 20W speaker off one channel, or do they need to all be the same tap setting (i.e all 30w)?

Recessed Rack/Enclosure

I’m looking for a wall rack/enclosure I can recess into a cinderblock wall. New construction, so they’ll build the cinderblock around it. It needs to be flush mounted when done. It’s in a professional looking space, so can’t use standard electric box enclosures.

Looking for something 10U-20U, but am flexible on size. It doesn’t need to be full depth, 6” would be enough. Mostly being used to rack a few control units, so nothing deep. They don’t want them wall mounted, but in some form of cabinet/rack

Trying to find a stock solution to buy instead of custom fabricating. Looking for a plexiglass door. The end user wants to “see the high tech blinky lights”.

The architect is stumped, the electrical sub is stumped; so time to ask Reddit!

Huddly L1 and Zoom Rooms

Hey all,

after failing to get ahold of Zoom technical support, not a surprise, I'm wondering if the fine people of reddit might be able to help me either get in touch with their support or know where to look for this.

I have a Lenovo Core with Logitech Tap w/ Zoom Rooms.
I have a Huddly L1 Camera system
I have a Shure P300 processor

When the room is unlicensed the L1 Camera system works as it should in the test zoom call or joining another zoom call. When the Lenovo core gets licensed with Zoom Rooms and pulls the global settings from the company, the Huddly L1 system no longer switches between its 3 cameras only every uses one camera and is very slow to crop in on the person speaking.

This leads me to believe it is some setting somewhere from the previous integrator that I can't seem to find that is blocking the L1 system from performing like it should.

Licensed or not, the Shure P300 works as it should over USB to the Lenovo Core.

Does any one have any thoughts on what setting the Lenovo core is pulling from the cloud that is tanking the L1 performance? Any help or thoughts would be greatly appreciated!

Technical question for engineers in this sub

I'm an artist who was recently given some equipment to use for an installation I'm doing. I need some guidance or assistance with how it will/should be hooked up. Apologies for any misguided questions or incorrect terminology.

The gear:

  • (1) Extron XPA-2001 - 70v amplifier at 200watts.
  • (4) SolidDrive SD1-sm inductive drivers with the PEM-W equalizer blocks at 8ohm/100watts max
  • (1) RDL TX-10B 10k ohm bridging input transformer
  • (1) RDL ST-PA18 18 watt power amplifier at 8ohms
  • (1) RDL STM-1 microphone preamplifier
  • (1) RDL STA-1 Universal line amplifier
  • (4) 12"x16" sheets of 1/16" sheet metal

The sources

  • (3) plate contact microphones with 1/4" unbalanced out (mic level)
  • (1) guitar output (instrument level)

The goal:

  • To either use a guitar or the contact mics to send signal to the amp which then powers the induction drivers that are affixed to 4 metal plates.

The questions:

  1. From the output of the XPA-2001, can I feed the RDL 10k input bridging transformer before hitting the first driver?
  2. Do I need a separate transformer for each driver?
  3. Is there any wiring scheme (series, parallel or S/P that will allow me to use this amp with these drivers safely? I don't want to start a fire in the musuem or anywhere really including my home where I'll test this out.
  4. Will wiring the 4 - 8ohm drivers in series effectively bring the wattage from the amps output to 25? Is that how ohms law works?
  5. Are there any other methods you'd use to get this to work based on the equipment that I've listed?

I'd like this to be as loud as the amp and speakers can handle safely. I'm not trying to compete with Van Halen but if its loud enough to be difficult to hear from that would be sweet. Grateful to you knowledge and thank you, kindly.

Biamp meltdown

Disclaimer: ex-live event video engineer now managing an integrated auditorium… so still wrapping my head around DSPs…

What could be some possible causes for a few Tesira Forte CIs ran though a group of XEL 1200.1s on a m4250 network mixed with Dante and control (NDI in vlan) to all go offline and throw faults when one of the DSPs is power cycled.

Biamp has logs and such and is investigating but have been all day and no word back yet.

Portable Teleconference Device Recommendation Request

Hi all,

Hoping to get some advice on this, it seems a simple question but I'm out of my element here. We need to replace our Meeting Owl Pro and I'd love to get recommendations on the best options out there for portable teleconferencing devices. I know there are mixed feelings about Meeting Owl, but it's served our purposes quite well over the last few years, just getting old and starting to have some connectivity issues.

We need something that's portable as we travel to meeting locations. We usually use Zoom or Google Meet for teleconferencing, and plug the Owl into a laptop. Our meetings are on the smaller side, usually somewhere between 5 - 50 attendees with some minimal screen-sharing or whiteboard presentations. We like the 360 feature and the focus on presenters, as well as having the speaker/microphone built in. Essentially, it takes very little time to set up, is all-inclusive for our simple purposes, and is easy to transport.

Additionally, if anyone has an opinion on Meeting Owl 3 vs 4 that would be great. From what I see it's just a better camera and updated connectivity options, but if anyone can chime in on specific features or whether it's worth it to upgrade that would be great.

Anyone experience pulsating feedback on a dead connection with Qsys/Crestron?

I have had a cascading failure of wireless mics and the result is a crazy pulsating feedback loop through the house speakers, even with the receivers completely disconnected. I'm guessing the feedback is unrelated to the mic situation other than it put a spotlight on it. Anyone have a guess as to what could be causing the pulses?

2x3 Planar Video Wall Connectiond

I recently acquired 6 - Planar LX55HDS-L monitors and mounts that were in a 2x3 configuration. I do not have any of the power supplies or a video processor. The 48V power seems simple enough, but the only video input appears to be LCD In over Ethernet. I have not opened the panel to check for other inputs. How do I send video over CAT6? I see a lot of devices to extend it over CAT6, but it converts back to HDMI to plug into the display. Could I use those devices and just plug it into the RJ45 on the monitor?

Portable speakers for meetings with 80 attendees

I mainly do IT but have enough AV skills/experience to run a few meetings each year. Renting is getting pricey, so I'm looking to complete my equipment inventory with a pair of portable speakers on stands, for a room that usually holds 80 people. These are educational meetings where people just present a powerpoint and speak into a podium mic. Occasional use of a wireless mic for audience Q&A. Barely any music.

Since it's only 2-3 meetings a year, I'm not looking to spend a lot....would like to get away with just spending around $200 per speaker, if possible.

What would you recommend?

Novastar VX1000 blackout mode...IP commands?

Has anyone had experience controlling a Novastar VX1000 with 3rd party control? Crestron? I'm looking at the IP commands but dont see any commands for blackout. I'm basically looking for a way to kill the video wall when the system is off. Even idling at black would be OK. I see commands in there for Preset recall. Would you set a preset with 0% brightness? Any ideas?

Logitech rally bar sleep mode

Hello, I have a teams room with a smart tv and a rally bar mini with tap ip with power saving mode on on the teams admin side.

The tv should display a black screen after 10 minutes of no use but instead it is showing a screen that says the hdmi is disconnected. Is there any way to change this or is it a tv issue?

Crestron MTR + Clickshare CX-50 | BYOD Mode

We are an integrator and I need to get help from the community with a question, I have a Crestron UC-CX100-T MTR and I also have a BARCO CX-50 for wireless presentation, everything works fine except BYOD.

When I connect the USB-B and HDMI to the Clickshare, the change in the MTR is done correctly and I can use the room in BYOD mode, but this only happens if I connect it manually (all the equipment is inside a rack).

Do you have an idea if I can have an automatic priority selection, the idea is to leave it always connected and I can manually activate in the touchpanel the BYOD mode. Or maybe set a priority to the USB (like when you do it with a lightware).

Thanks in advanced dfor your help.

Thoughts on A&H AHM processors and Custom Control?

I'm an AV Tech at a medium sized sports arena. I do not work in install. We recently had one of our installed systems in a lounge go down. It was a Crestron button station controlling a EV N8000. This has raised the question of upgrading the processor. And I'm looking into purchasing the A&H AHM-16 to replace the EV and possibly purchasing a CC-7 to replace the button station. Anyone have experience with the A&H installed systems?

Hoping to handle the upgrade in house, and they seem good to me on paper. Also hoping to use the Custom Control app to control basic functions of our A&H dLive. But that's not a necessity at this moment. Thanks in advance.

Poly x52 going to reboot loops

We bought the new Poly X52 and encountered an issue right out of the box. When trying to upgrade the firmware, it goes into a reboot loop with no way to fix it, not even with a factory reset.

HP has replaced the unit three times, and all of them have had the exact same issue. We were planning to outfit our new office with the entire new Poly series, but now we're extremely concerned with all of this going on.

Is anyone else experiencing the same issue?

Kramer - One Source to Two Endpoints

I’ve been recommended Kramer products as a compromise on Extron, but I’m struggling to find what I need in their range. I’m UK based.

What I’m looking for, is one unit with a single HDMI source, with pass through to a local HDMI monitor. Throwing said HDMI source over Cat6 (one or two cables) to two ‘receiver’ units, each having their own HDMI output.

I don’t need audio, IR or anything else.

Any ideas?

Thanks in advance!

timer clock in conference room?

I am having a conference room having Crestron CP4 AV control processor. I want to install a digital timer clock (like a stop watch) showing time left to the person who is presenting so that he completes his presentation on time. I want this digital timer clock to be fully controlled (setting the duration, start, stop, pause, reset, etc) from from Crestron CP4 via touch panel on which similar UI need to be there. What all options are there ? What is the industry practice ?

Outsourced designs?

Hey guys, I’m an AV designer that's tired of working for "the man" and kinda wants to venture out. I'm looking to validate a business idea, and I’d love your thoughts. Just wondering on the feasibility of this. I wanna start a stand-alone design business, think of it like freelancing but on a bigger scale where companies could just outsource their design work to me. Process would go something like this: They could hire me on a contract term, they send me what they want designed, i use their labels and all then send it back.

BTW this is a throwaway account.
