IF-AN/DM - where are the jumpers?

[snafu]

Hello everyone,

this is maybe a dumb question, but: I've found a "manual" for the IF-AN/DM here. It implies that I can set I/O sensitivity via jumpers. There is also an image of the card, but I can't see the jumpers.

I'd like to set them to -11 instead the default of -16 dBFS.

Now, here is the caveat: my DM3200 is build into my desk. It would take some great time and de-montaging to get to it's backside. However, I can access it's interior - to the left there is the housing of the internal 2-slot bay, covered by a platine. I am not a 100% sure, but I think with some caution, I should be able to losen it, and access the cards. However, since they're plugged in from the inaccessible backside, I can't pull them out. If I knew where these jumpers are, I could make an educated decision whether it is possible or not to set them under these more or less not so optimal conditions.

Can anyone provide a picture of the card, indicating where these jumpers are?
Thanks a lot,

regards
snafu

I could get you a picture, but I'll have to take it from Google too, so you best go there. On these pictures, you can see on the IF-AN/DM circuit board little black rectangular things with white selectors inside them (Google dip switch separately and you see what they look like). You see them in groups of 3, 2 and single ones, for a total of 32. These are the 'dipswitches' - they're not really jumpers. They have two positions, ON and OFF and you can set them with the tip of a pen. They should each be indicated with their switch number (SW 011, SW 012 etc) close to them, but I can't make that out on the pictures I found.

They are close to the card's mounting plate with the connectors - and your AN/DM must be in Slot 1, or in Slot 2 without anything in Slot 1, otherwise you won't get to them with the card installed. Might be tricky anyway - also to see which one is which. Good luck!

Thanks for your answer, Arjan. I already had some "good" google pics, but didn't know what to look for. I think I know where they are now, and what they do look like - unfortunately (if I'm not completely mistaken) I have to set them by pressing down of that switch? Phew - this could be far more than tricky - besides the AN/DM I have the FW/DM mkII installed^^

It might still work though, without having to remove the DM from the desk, but it would be very tricky. I have an endoscope cam here, so visuals should not be a problem. But the workspace surely will be...

Maybe I should put the question otherwise: by setting the sensitivity to -11dB - do I get a reasonable benefit when connecting a dynamic mic directly (!) to the AN/DM? I propably better take an educated advice on this one first, to see if it would be worth the grind...

To start with your last question, I think it will be problematic to get a good level from a dynamic mic from -11 dB, but it depends on which mic and what you record with it ofcourse. Guitar amped cabinet with an SM-57 in front should be OK ;-)

You could give it a try with one input channel on the AN/DM. You see on the sheet that you need to flip 2 switches to change 1 channel. 11 and 21, 12 and 22 etc. If you can find a set of two you could try, to see if you can actually flip the switch and then try if it gives you enough level. As you have the IF-FW/DM I assume it is in slot 1, so on top of this card. I wish you luck..

BTW, you don't press down on the dip switches, you have to slide them between On and OFF. Check this: https://www.google.nl/search?q=dip+switch

anyone got the manual of the analog card?

The "manual" is supposed to be online - but I remember it quite disappointing: it's been a scheme and a level setting chart. I have the latter as pdf - if that's of any use for you, let me know, and I'll send it to you.

Is there something specific you're looking out for?

 

[henkmeid]

If you could send me it, that would be great. Just figuring out the level settings and all the dipswitches, so many of them

i know a few folks would love a copy - if you could also post a copy in the documentation and manuals section for future use by forums members that would be super helpful!

I'd really love to - but I cannot upload files directly, and am no Admin.
However: I provided links to the only two files I have.

Don't be too disappointed: as far as I know, this really is all Tascam gave to the user (the "manual" of the IF-FW/DM isn't a novel either...). Anyway: I could be mistaken, but I think there is a drawing of the card somewhere. Should I find it, I'll post it.

those links are great, thanks. the one page of jumper info is definitely useful and i have never seen it before. most grateful, good luck w it!
