Transmit Wireless Stereo Audio from Computer
« on: December 02, 2023, 10:49:06 AM »

Hey!

So did the forum searching already and found a few general ideas on a way to do this, but nothing specific. Many of them from over 6 years ago as well so some things have been discontinued.

Here's the deal:

-Need to transmit stereo audio from a computer located at a scorer's table in the middle of a gym to input of mixer in closet. Hardwired is the way to go, but no practical and affordable way to do this
-Distance will always be under 100ft
-Trying to keep cost under $1500 total
-Tried a 2.4GHz transmitter, and works great when the gym is empty. But with lots of people in the stands...no reliability as you'd expect
-I want hardwired power on both transmitter and receiver, nothing running on battery. (That seems to rule out using a turnkey IEM system with a beltpack)


Someone thought that a Shure PSM IEM transmitter and ULX reciever could be made to work together to get stereo wireless audio? But couldn't track down the specific devices this might be.
Suggestions?

Thanks!

Why does audio in a gym have to be stereo?  Get one of the PCDI boxes from the other thread, make it mono and use any decent wireless you have in stock.

Using the "buy once, cry once" mentality, I'd much rather invest in a system that is capable of stereo if possible. (The PA in the gym is setup for stereo.)


Now, if there truly are no capable, relatively affordable systems to transmit 2 channels, then it isn't the end of the world.

Assuming all the audio is prerecorded,  put a PC at the mixer with your audio player loaded.  Remote into it from the scorers table PC and trigger playback as desired.  Still have wifi possible issues, but you could use 5 gig versus 2.4.

You always have to do the right thing, but that's not enough. You have a job where people have to trust you. You have to LOOK like you're doing the right thing.

Maybe one of those Alto Stealth wireless 2-channel units would suffice. Ive not used one but a friend does for wireless satellite delay speakers. Is battery life not long enough or can you not do a switch during an event?

Oh, that's what you were going for...

Since this is going to be run by parent/coach volunteers at most events, trying to get rid of as many variables, as well as make it as user-friendly as possible.

The Saturday morning calls with someone trying to figure out why the audio isn't working and it is because the battery has died is something foreseeable I'm trying to avoid!!   ;D

If you're running power, don't you already have cables on the floor?

What kind of audio is being played back? Music from a playlist? Spotify/Apple Music? QLab tracks? Is the playback device the same all the time or are people bringing their own laptops/phones, etc. for playback source? If so, there's a lot more issues that can happen than just the wireless connection between the source and destination!

Knowing why the audio source has to be at the same spot as the playback controls would help narrow down the best solution. Remote controlling a fixed audio source will always be a better solution for unattended systems.

If there were an XLR input in the wall by the scorer's table we'd be in business! But sadly, the AV rack was added after the gym was built and is decently far away.

Now, if there are no decent, affordable wireless solutions it may come to finding a creative way to get some cables over there.

The source is a PC that is sending video via HDMI to a screen built into the scorer's table. Audio will be from several apps on that same PC. Spotify, sound effects QLab type app, video playback, etc.

(Just FYI - This is for middle school sports at a grade school run by different volunteers, so that may help with the level of solution as well as simplicity we are aiming for.)
