Hi, I'm new here.

I have had a 2408 for many years that has served me in many ways but most recently I've been using it as a format converter to go from ADAT to TDIF on one bank only. I've recently had a need to use more than one bank of ADAT to TDIF conversion but I cannot get it to work.

I have 2 ADAT sources that I'm interfacing with TDIF inputs on a Tascam DM3200. When I set the Source on the 2408 to ADAT A, B, C and input unique signals on those respective banks I can see corroborating signal indication in the TDIF signal meters below (below the ADAT input indicators). However, when I try to get this signal to present itself on the Tascam mixer it doesn't work. If I change the source on the 2408 to A, or B, or C then I see the whatever signal is present at the single source bank reproduced on all TDIF banks. I can also get this signal to come out of the Tascam mixer.

I know I am clocked correctly and that my mixer is setup to receive signal from the TDIF inputs. What I don't understand is that according to the 2408 user manual I should be able to use it in the fashion I've described. Am I doing something wrong? Does this work for anyone else? I bought this unit new in 2004 and it has never had any problems when I was using it with the 424 card.

Thanks for your input.

For the record, I'm using all this stuff on a windows computer.

I don't think I've tried to route two ADAT sources. There are quite a few posts about standalone mode, thought they may be hard to search.

Most are along these lines:

Hi Doug, according to that post in the link it sounds like what I'm trying to do should work perfectly.

My source is set to ADAT A-C and my TDIF outputs are connected correctly but nothing is actually being output at all. I can only get converted output if I set the source as ADAT A or B or C. The indicator LEDs show what would be the expected activity for unique conversion across ADAT A-C but unfortunately there is no output.

I'm just trying to confirm that this feature is broken or incorrectly documented to exist.

Hi, My Exact issye. Will Upgrade to thge latest Mac Pro rack but rge MOTU card is no longer support. I have the didgital Mixer Tascam 3200 DIgital. If I replace the computer I am disconnected from the mixer and studio is crippled. Using an older verion of Logic due to my older MAC Pro 2013. Frustrating.
1. What I can do with my MOTU 2408 to use it as a converter to TDIF with No MOTU card
2. Get a similar Digital Mixer - which is ok using newer MOTU technology.
Anyone have a studio wiuth the latest MAC Pro, Logic latest version, and what is the solution )choose the correct mixer)
Thank you.

I used my 2408 in stand alone to convert ADAT to analog and back. There was a limitation of 8 channels in stand alone mode. Mine was a 1st gen, however, not a mkIII.

My FOSTEX FD8 could only record eight tracks simultaneously from an ADAT source, otherwise it was limited to two only. I fed it with a Mackie 1604 because I could take a direct out from each of the eight preamps. The 324 let me dump all 8 tracks of ADAT simultaneously into my Beige G3 when I got home. The entire portable rig fit in a small case and could be laid out on a card table — I was in heaven. My Sweetwater guy was convinced that it would never work, BTW, but it did perfectly. This was how I started with DP although I did my first few sessions in Audio Desk while waiting for MOTU to ship my upgrade to DP 2.7. Was that really 25 years ago? Oh my…

Looking at these descriptions and the manual again, it looks like it should work. I wouldn't rule out the routing in the Tascam mixers, since that's common to both posts. I know I have frequently ruled something out that I was "certain of", that later turned out to be the problem.

The only alternate test I would think to try would be to loop the ADAT back to it's source, or to another ADAT receiver, and see if that will pass all 24. That only tells you that you do or do not get pass through, and whether the source selection options control that pass through, but if that seems similarly broken you have another clue. Someone with a 2408 in line with an ADAT stream going other places along with Tascam sources, who switches between them, might know. Broadcast or transfer house.

TDIF-1 is not something I hear about anymore, not sure what other options exist these days.
