What's the best way to hook up the Capy 320? I don't have an amp per se. I route everything through my 2408 and monitor/mix through Digital Performer (By now you know I'm on the Mac platform...). I'm having a hard time figuring out how to integrate this into my current studio. Any help would be greatly appreciated! I'm extremely new at this so please feel free to explain the "obvious".

Thanks, Jon...

You should be able to connect the digital outputs of the Capybara to the digital ins on your 2408. Use the AES/EBU to SPDIF adapters that came with your Capybara (XLR to RCA).

Hi Jon
I use the 2408 with the cappy 66 and I connect it to the MOTU via S/Pdif using the convertors as mentioned by SSC. Make sure that Kyma is set to take it's clock source from it's spdif input. I have found that sometimes after bootup I have to unplug the spdif into the cappy and count to twenty , and then re plug it to get it to sinc correctly.
The cappy 66 only has two channels where as your cappy has 4 or 8 channels, so you could connect the extra 2 or 6 channels via the analogue ins and out. But if you want to work totaly digitaly then adding the MOTU digital interface, (I think its called 308 but I'm not sure ) to your setup is cheaper than buying an 8 channel AES EBU to adat convertor. You already have the MOTU core system so you won't need an extra PCI slot in the mac. You just add it to your current card. The 308 has 8 channels of AES EBU in and out, 8 channels of spdif coax in and out and 8 channels of spdif fiber in and out.
Avoid TDIF where ever posable. I have Tascams own Tdif to AES converters that don't even work with Tascams own DA88.

hope this helps

Thanks for the replies. I think the problem I'm having is more with the setup for the 2408. i'm not getting any sound. I'm getting input lights blinking when I play a sound, but nothing appears to be coming out. What software settings should I have? i'm pretty sure the hardware is set up properly. i may not have the output setup properly with Kyma 5...

Thanks again!

Jon

Hi Jon

It all depends on what else is in your set up and how you intend to use it.

I am using cubase on the mac and an Yamaha01V Mixer. So I connect my monitoring to the O1V and link the O1V to the Motu via ADAT Optical. I've set up the Motu interface so that bank 1 is the ADAT to and from the mixer and output source 7&8 get spdif instead of "from computer". Bank 3 is set to spdif and gets it's source (1&2) set to ADAT 1&2, because this is the AUX 1&2 on the O1V. This means that even if cubase is not booted up the, Kyma can send and recieve signals to and from the mixer and remain in the digital doman right up to the DAT recorder(attached to the mixers spdif).

I am guessing that you are connecting your monitoring system to the monitor output of the motu, and that you haven't yet desided which Mac Harddisc recording software you are going to use.

In this case if you set bank 3 to spdif and bank 1 to analogue then because the monitor out is a copy of analogue 1&2 out, then by setting bank 1s source 1&2 to spdif you should get Kyma's output through the speakers , but nothing else can get to the speakers at this time.

If insead, you put analogue source 1&2 back to "from computer", then by using a programme called cuemix (which is on the motu CD), you can route and mix the spdif signals in with any other signals attached to the motu.

When you have decided what Mac Harddisc software you are going to use, this would then do the job of cue mix(assuming that the software has it's own built in mixer.

On the top right of the motu control pannel is a selection box labled monitor out. This is a lie and has nothing to do with the monitor. What it actualy does is chooses which output the Macs built in sound will be routed to, Thats asuming that you've installed the Motu's apple sound manager extention. This doesn't get installed by default. You have to use the motu installer a second time and select sound manager for install on its own. Also you must then sellect the Motu's PCI card as output in the Mac's "Sound" control pannel.

I've made asumptions about you setup but if you let me know what you have and what you are trying to achieve , maybe I can help out a bit better.

Also you must make sure the sample rates match. I normaly use 44.1 khz as is will probably end up on CD.

hope it helps

Hi Pete,

Thanks very much for your help. I think this is exacly what I need. I'm away from my system at the moment so I can't set things up, but I thought I'd let you know that I'm using Digital Performer 3.0 as my Audio/Midi software; neglected to mention it before...

Thanks again for your help!

Jon
