Hi All,
Looking for the simplest and cheapest way to set up 48 individual speakers on individual audio channels. Maybe there's a software hack for bluetooth or wireless audio receivers that could route the channels or similar?
Or would the best solution be daisy chaining a few adat converters and running the outputs straight into active speakers?
appreciate any response.
All the best,
Jeremy

Active speakers makes the speaker end simple. I see the problem as coming up with 48 discrete signal sources. (Or perhaps they are discreet...)
What is the application? DO you have 48 different signals? Or do you merely want to individually control volume of 48 speakers, all playing the same signal?

If you use powered speakers and a 48channel mixing desk, (Allen & Heath GL series would do), use the insert out connectors after each channel pre amp and there is 48 individually controlled signals from 48 separate pre amps.
Any 1 of 48 In to any 1 of 48 Out?
More than one Out to any In?
Oh, this could be fun! Check out the Mitel MT88xx crosspoint switch arrays. E

I like Snell's mixer idea. A 48 channel mixer used as preamps is a lot less expensive than 48 preamp units. Unless you have a 48 signal source already.
You'd need something like an ML5000, which I can say from working with an ML4000 for a few years that it's not a good idea. That thing was a four-man lift.
You wouldn't have much routing capability, either. It'd work as 48 preamps, but if you wanted to route a few of them together, you'll run out of aux sends eventually.
I'm with mickeymoose on this one.

The ML4000/5000 has inserts on each pre amp output, exactly the way I would go if I had a need to.
Absolutely Chris661 but imagine the cost to the person wanting this system, Megga Bucks, bad back and loads of hassle.
On the other hand, imagine the huge chunk of equipment he'd have if he used 48 separate preamps. If this were a common need, there would be a commercial piece of equipment to do it.
There are! Several.
Me, I would use a load of Dante equipped powered speakers (Maybe even Dante POE boxes if the required power is low enough), and some simple network infrastructure, DVS works well if you need is playout or something like MAX/MSP, so get the appropriate stage boxes if you need live input.
Routing is flexible and simply configured on the fly using a PC connected to the network, and any Gb switch will work for distribution.
Not cheap, but 64 channels of anything is not cheap.

Multiple unicasted streams of compressed audio (e.g. MP3 encoded) could do it. I have been working on something similar, just not for so many clients.
No need to compress for this, you can stuff 64 channels @ 24 bit 48K down a single 100Mb/s link without needing any compression (Netjack on pi's could be an approach if you dont want the off the shelf convenience of Dante).

I'm still very intrigued as to why would anybody need 48 audio signals played simultaneously through 48 speakers in the same place.
Hey duffdisco, would you care to describe your needs a little better?
Won't hold my breath, since you dropped this question and didn't check answers since.

hey all,
Thanks for answers, since then I have been looking into the Dante software and seems the most logical.
I'm working on an art installation - 48 speakers to begin with but looking at developing this in the future with more.
So I've come to the conclusion that I either need an IP speaker or a network device that has audio out which I can plug into an active speaker or an amp. This is so i can route the audio channel.
At the moment it's looking like it will cost a fortune though so I'm hoping to find maybe a raspberry PI type of device!
I'm looking at the following set up;
DAW with virtual soundcard software like Dante gives me the outputs and channels over cat5 > ethernet/cat5 > 48 port Switch > ethernet to XLR/Jack/RCA > network device / dante device > amp or speakers
just need to find that cheap solution for the network device.

Ok i got all the speakers working!
What i really need help with now is a maxforlive patch or something similar that can map out the outputs on a channel with xy type axis grid. Map the outputs and be able to automate between them on one channel. Can anyone help here?

When I did this ten years ago (only twenty-four outputs, but it could easily have been increased by the addition of another MOTU interface) all the output routing was in the Pyramix DAW. A personalised program, as I know the guys from Merging very well, but more of the complexity was in launching tracks, or sets, than in output routing. Added to this was a single pan/effects module driven by the narrator's mic, that could
Being Dylan Thomas' 'Under Milk Wood', very few of the individual sources moved during their segments, and I believe we had two 5.1 outputs for Ocky milkman, Willy Nilly postman, rhyming children and goats (oh, and the drowned men at the beginning), and a rack of balanced mix amps so directs, stems and live mic could feed into the same loudspeaker- cheap and cheerful.
As we were impoverished we couldn't get all identical loudspeakers - some were active (many thanks PSI) , some ran through racked power amps. Due to difference in sound colour between the different units, any group had to be all the same technology, and the 'map' showing auditorium, speaker placement, speaker model, amp channel, mixed sources and level was very precise, and took a week of rehearsals to finalise. There was little space for improvisation on the technical side. so there was a separate production with announcements on the tracks of the contents, with pans between outputs and a separate track to feed the pan narrator module. Tecchies and narrator would wander round the auditorium, or dash back and tweak something, for half an hour before the public arrived.
Every spectator got a slightly different mix, got an individualised performance, but hopefully all heard all the words. Nobody tripped over a cable, nor got lost finding the lavatories, so I hold the experiment up as a sucess.
