Auracast transmitter tests

Welcome, Ken. You do not need to worry about the real life numbers as Auracast is like FM radio station, the number of receivers does not impact the performance.

Auracast will be massive and easily smash the number of fm users.

The question is, in the real world, what is your experience of the most concurrent users listening at any one time.

I know in theory it is umlimited but I want to find out if specific transmitters have a limit.

Limitations will be physics based and equally to blame on the environment as the transmitter. If you are close enough, if there is enough signal strength, if it bounces off walls well, leaks through particular walls well enough to receive it.

This is somewhat like asking how many people can fit in the auditorium. How does the transmitter maker know? They might be able to say that with a particular receiver, in an open field, they can get 50 meters away. (I’m making the number up). When you go into a particular room or place in a building (maybe a wing) the issues with that bandwidth are non-trivial in figuring out propagation of the signal.

This is like the earlier discussion regarding “logging in” which doesn’t apply to this to an extent. Perhaps there is an application in mind where an answer could be obtained experientially? How high is up?

I just want to know what is the max number people have had on a broadcast. It really is a simple question.

Ok. However many people with Auracast-equipped aids or buds (assuming no persons without the right equipment) that you can cram into the room. Hearing loss is not essential.

It would be nice to test ear buds in school hall to see the maximum number the Auracast could broadcast to. Language center would nice.

Absolutely everyone within range of the transmitter. You could hang people by their ankles from the rafters like bats to increase the number.

I’m having the same problem with the FlooGooPHA120. of the aurocast being too loud. It’s hooked up to my Windows 11 Dell laptop. I turned the sound down all the way in the app, and also the laptop, and it still is too loud. I have the Jabra Pro20’s custom. So I’ve gone back to using my Phonak L90’s if I want to stream from the PC. The Jabra’s don’t connect to the laptop without aurocast. So, yes, help!

Homespot has a utility you can use to attenuate the output from the BA210. You can ask their support for a link to download it.

Tap it to start streaming.

Our engineer suggests adjusting the volume directly from your computer or phone’s audio settings or app. Could you please give that a try and let us know if it helps?

To adjust SQ broadcast volume, visit https://www.qkaudio.com/support-ba21027 and select QK CastTool.

Feedback from GN users shows that they usually settle with -18dB to -30dB. I suggest to start with -24dB, adjust upward/downward until a level that you can use the Jabra EP app to fine tune the volume comfortably. Things to note

1. QK CastTool is a Windows PC/WebApp that runs on web browsers. No software to download or install.
2. Use Chrome browser, version 100 or later. Edge might work. Safari definitely doesn’t.
3. Use a USB data cable to connect the BA210 to your computer. Charging-only cable won’t work. If you have purchased BA210 v2 standalone model, there should be a white USB data cable in the box.

I have Jabra Pro 30 from Costco and have them working with BA210 v2 streaming Auracast… the 310 is a receiver only I believe.

Thanks… that fixed my high volume problem. Trying to find best level for me… looks like higher than -18 db
