Hey Guys
So after a short 13 months, I received half my order from RM. The SuperBeast DA is on the way soon, I'm assured....
I'm trying to figure out the best way to hook it up and could use some insight from you guys.
My current setup is using a Motu 2408mk3 which has three banks of 8 channels I/O. Banks A and B are taken up by Apogee AD/DA 16x's, and Bank C has my Burl B2 AD. So 18 ins 16 outs.
To add the RM AD, I tried running the optical out of the RM into optical in on my Mac Pro. Made an Aggregate Device with the 2408 and the Built In Digital In. I was able to get the RM to show up as Inputs 19 and 20 in Logic, but there is a huge latency that I can't seem to get rid of.
My word clock setup (which is probably wrong) is,
Burl (Master - has two W/C outs) W/C out 1, to Apogee AD16x W/C in
Burl W/C out 2, to Apogee DA16x W/C in
Apogee AD16x W/C out, to RM AD W/C in.
If the Burl had a 3rd W/C out, I would have used that going to the RM, but it doesn't.
PS: If I choose "Built In Digital Input" as my Input Device in Logic's Preferences, I get the signal without the latency, but then I lose all my other 18 inputs.
Can anyone tell me what I'm doing wrong? Thanks so much!

The best way to run your clocking would be to use one WC out from your Burl if it's the master. Go to radio shack and buy a few BNC T splitters. Come out of the Burl WC and have a T on the Motu WC in, then from the other side of the T run a WC cable to a T on the first AD16x WC in, then from that T run another WC cable to another T on the last AD16x. From there run another WC cable to another T on the RM WC with the cable going in one side of the T and then a 75ohm termination plug on the other side of the T on the RM. The Burl should have plenty of power to send WC to just 4 devices.
If you do it this way it ensures all your gear is synced on one transmission line and all are receiving the same clock signal.
Does the RM have a RCA type SPDIF I/O? If so you could utilize that so your Motu is the only device running and you won't need to make an aggregate device. I'm not sure how you are wanting to set this up so thats all I can suggest with the info you gave. Hope it helps!

All I'm really trying to do is to be able to use the RM AD (and the DA when it arrives) without having to switch out my Burl. The Motu has SPIDF but it still only has 3 banks, which are all being used. I was hoping the Mac Pro digital I/O would be the ticket, but I'm getting a ton of latency. I tried researching the Mac Pro digital I/O, but couldn't find anything that would be xplain the latency. Thanks for your help again! Much appreciated! |

Also, if you are even a total novice and have a soldering iron, you can make the WC termination plug with parts from Radio Shack. Just buy yourself a solder type BNC connector and solder a 75ohm resistor from the center pin to the outer contact. If Radio Shack doesn't have 75ohm resistors and have 150ohm, then just take two 150ohm resistors and solder them together in parallel and it'll give you the 75ohm's as well. Good luck! -J |
