The Rane notes https://www.rane.com/note110.html are a useful reference for equipment interconnection. For The LS9 to RCA No 6 is the one to look at, no link needed.

You can adjust the output level using the attenuator for your chosen output port(s)

You could patch two spare ports to parallel your main left/right outputs if that is your desired source.

Setup, (output port setup)

Select the appropriate Omni port

I'm not an expert on this but the default channels for scenes on an LS9 are channel 1 for scenes 1-128 Channel 2 for scenes 129 to 256 and channel 3 for scenes 257 to 300.There is an offset of 1 between midi and the LS 9 scenes

so LS9 scene 1 = Midi 1-00 scene 27 = 1-126 scene 155 = 2-26

It would probably me easier to move the other units than rewrite the LS 9 table.

Brian

Its a bit tedious but you can reprogram the channels on the LS9. Page 180 of the manual gives you the basics. You will need to define each scene manually and also clear the existing scenes, good luck. I tried a couple of random scenes into channel 5 and they worked.

It might be useful to be aware that you can also use a block of frequencies in channels 64 and 65 under the channel 38 licence. You would need Trantec S5.5D rather than G.

so some good and some bad news

Hi Stephen

The channel 38 shared licence gives you a maximum of 12 channels, Bank 7 in a Trantec S5. or the first 12 channels in Bank 5. You can't mix banks without interference problems. If you need more than 12 channels, you will need to consult Ofcom who will allocate suitable frequencies. These are fairly expensive in comparison to the shared licence. Schools are NOT exempt from the licence requirements whatever they may tell you!

Hi Sam

This is similar to the one that I used.

I can't find the actual unit. It was available via Motorola and just shy of £1000 around 12 years ago. The marketing feature at the time was that it was in use by those protecting their great leader but also useful with BA sets.

I don't know if the PTT would be useful, I used an under arm squeeze pad. PM me if you want a chat.

Brian

If intelligibility is important a bone conduction microphone could be the answer, though they are not cheap. I've used them in pressurized suits with good results.

Brian

A throat mic being dynamic will require a dc blocking capacitor and the audio gain on the belt-pack turned right up. It should be doable. The quality won't be great but I suspect that is not really relevant.

Brian

I vaguely recall a link on the pcb, perhaps a zero ohm resistor?

Brian

Are they 4mm threads?

No they are M3
