it's working
but now i got another problem ... i'm trying figure out what i'm doing wrong
Had to laugh at this post...."Its working, but now.....I've got to figure out what I did wrong"....LOL. Been there.
OK. You do not need a 2408 anywhere in the chain. I believe you have an MX2424, is that right? And you have it hooked up with the TDIF Cables? Well, that would be EXACTLY like the way the guy in the video has his hooked up. He recorded directly into his mx2424 (not exactly sure what he recorded into, just guessing). Now, he is playing back what he recorded and is mixing on the DM. As Dan said, this is common practice to mix out of the box (OTB). The post I send you, that you quoted, is the proper routing for assigning the MX2424 returns back into the DM for mixing. When it sounds right, send it out the DM's stereo buss and record that.
As for an overall picture for effects use in the DM3200;
You can assign separate EQ, Gate and Compression/Limiting to every individual channel, from CH1-32, from within the channel's module screen, mainly because these are "serial" effects, and are typically used at a 100%mix. The full signal goes in, gets effected, then the full effected signal comes out.
The two TC effects on the DM should be more thought of as two parallel effect busses. For example, imagine having one really good stereo reverb and a really good delay in your studio, then assigning a varying bit of signal from each individual track to that one reverb and/or delay, to be lightly mixed into the stereo mix buss. That's how the TC effects are setup in the DM. As two stereo (or dual mono) parallel effects. You cannot have multiple, individual instances of these effects assigned to multiple, individual channels. But you CAN/WOULD have multiple, individual channels assigned and mixed to these two stereo effect busses.
