Help Going Wireless Displays?

[pio]

Put here because not entirely sure what section this really belongs in........

 

So, I'm trying to help a local church out with their technology needs, and they've got an interesting idea but I've never done it before.

 

Is there a way to connect speakers wirelessly, screens wirelessly (4, all displaying the same thing is fine), AND microphones (to go through the speakers) wirelessly to a Samsung Galaxy View SM-T670?

 

I was thinking maybe get one of those wireless bluetooth to RCA adapters Parts Express sells and use bluetooth for the audio.  They sell those usually for wireless surround DIY options, is basically what I was thinking.  Not sure 110% if there's a bluetooth option, but I'm sure there's something out there that's a bluetooth DAC basically.  I know Amazon sells some decent 3 packs of wireless microphones that come with a USB receiver that they talk to (I'd need to either find a Micro-B receiver / mic pair or convert).  Although I am curious what your guys' thoughts are on what the appropriate type of mic would be suitable for the situation.  So that handles KINDA audio, at least in theory?

 

But how can I get the 4 HDMI cables we have coming down the wall, and get those wirelessly into the tablet and duplicate the display on 4 monitors too?  Would I use like a Roku type device, or maybe a PC with appropriate Windows 10 capabilities of using wireless display tech or something?  Would that even work?  A $30 Roku sitting perhaps even up in the ceiling connected to the 4 TV's would probably be a lot easier to wireless

 

Picture very much related, its the back of his speakers (he has 2 just like this).  TLDR:  We're trying to get these + mics + 4x HDMI outs, wirelessly, from a Galaxy View with USB Micro-B, Bluetooth / Wifi.

Close, except we already have 4x HDMI cables coming down the wall already, and an existing HDMI splitter he's been using already.  Forgot to mention that part I guess.

 

I was thinking:
This + some shielded RCA's to the speakers (use bluetooth from the tablet):

Then use microphones similar to these (idk if they make with receiver USB Micro-B instead of C though):

https://www.amazon.com/Aisizon-Microphones-Microphone-A2d-Recording/dp/B0B4KLW9B2/ref=sr_1_2_sspa?crid=XFYG4BTVAQ35&keywords=wireless%2Bmicrophone%2B3%2Bpack&qid=1673500243&sprefix=wireless%2Bmicrophone%2B3%2Bpac%2Caps%2C270&sr=8-2-spons&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyUThaN05STzA2OTlaJmVuY3J5cHRlZElkPUEwNzYzMjg2M1IzM1dHQ0JSUEJSUiZlbmNyeXB0ZWRBZElkPUEwNDI5NTcyM1QyOFA0TVgxTlFNQSZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU&th=1

 

And then I guess plug a Roku or Firestick into the 4x HDMI cables going to the TV's and use wireless display to get the screen out?  (Already have an HDMI splitter)

 

Not entirely sure if that'd work 100% though, seriously it'd be so much easier on a PC lol.  I'm not 100% sure microphones will keep working on an android if you don't have an app open to use them.  So say they start a video, but then they want to use the microphone during the video, that probably won't work on an Android without switching the apps back over is what I'm thinking.  Or to be honest, if my idea above would even work at all.

I don't get what you're trying to do. What is the end goal here? 4 TVs all showing the same video feed?

Instructions for using Chromecast to cast to more than one TV or screen both wirelessly and with HDMI cables.

partway down it describes how to connect 1 chromecast to multiple hdmi cables using a splitter.

For the mics, I'd try something like these  FIFINE UHF Dual Channel Wireless Handheld Microphone, Easy-to-use Karaoke Wireless Microphone System-K036

We're basically trying to use his Samsung View tablet to be a mixer, speaker output, microphone input, AND display videos on 4 TV's (which we already have a splitter for HDMI).  But.....all wirelessly so the tablet can be carried around.

Okay, I think I see a potential plus with that setup.  The mics could plug directly into the wireless DAC (which then goes to speakers) and bypass the tablet entirely for mics.  THAT wouldn't be too bad of an idea actually.  Then tablet can just send audio over BT (for videos), and video content over wifi to a Chromecast, Firestick or Roku, into the splitter, out to the 4 TV's.  Yay!  That'll work!
