44.1 ADAT upscaling to 96K

[henkmeid]

Maybe a dull question. But I have some old gear which have an 8 channel ADAT out which runs on 44.1K.

If I run a session on my DM-4800 on 96K thru firewire to my DAW, will the 44.1K ADAT be upscaled or will this not work at all?

Hope my question makes sense

It won't work. If you're running the desk at 96k then you would have to also sync the ADAT gear in at that rate which sounds like it wouldn't work. You don't gain anything by upsampling to 96k. I would suggest capturing all that old stuff separately at 44.1k and then upsample in the DAW as required if you need to drop it into 96k projects. Hope this helps.

And what about S/MUX? I believe my old gear supports it, 4 channels, but does the DM onboard adat or adat card?

 

[cmaffia]

Yes it does I believe support S/MUX

 

[Gerk]

Yep the DM consoles do support it if you're older gear does (not all of it will).

 

[henkmeid]

Thanks guys! Appreciate it.

And what about The tdif interface? Do they support 96k?

 

[Gerk]

They do but it works pretty much the same was as S/MUX does with ADAT. THe higher the sampling rate the less channels that it can bring in at once. I think you get the same as ADAT, 4 channels per when using 96khz.

TDIF can do all 8 channels at 96k on the DM boards but the only thing that will except it is the Tascam X48 or Avid 192's and HD I/O's will allow input of all 8 channels of TDIF because the units upsample to 96k but will not allow output of any channels of TDIF at that sample rate.

Motu 2408 mk2 or mk3 with PCIE card can also do 8 channels of TDIF at 96k. Very affordable option if you just need to transfer some files or need sample rate and digital format conversion.

 

[29CountsNY]

8 Channels per TDIF connection?
Do you need the PCIe card to do it or can it be done with unit standalone?

 

[Tuviel]

Yes 8 channels per connection for a maximum of 24 tracks. I'm not sure if it can be done in standalone but the manual seems to indicate it can be used as a digital format converter I.e. ADAT to TDIF or analog to TDIF "at up to 96k".

However, I think the files need to already be at that sample rate if your input source is digital so as previously mentioned one might have to do the upscaling in a DAW.

Also keep in mind that TDIF use on the 2408 requires word clock sync. The protocol Motu uses does not carry a sync signal. Found this out the hard way. These are very useful boxes IMO.
