Hi guys,

SM58 mic [XLR connection] -> RNPreamp -> Benchmark A/D Converter [optical connection] ->

Edirol UA-101 Audint [USB connection to PC & Reaper] + [optical out] -> Audioengine D1 D/A Converter

-> KRK R5 Speakers.

Having read the ADC1 manual several times I still wonder if anything would be gained by connecting via USB to the PC.

----- am I doing it right? Any advice, please.

Not sure I understand what you are asking, but once your signal is sampled it doesn't matter how may hops it does, so long the devices are properly synchronized and the cables are ok.

So - if this is what you are asking - passing the signal from the A/D converter to the interface via an optical (digital) link or via USB or any other digital connection makes no functional difference. If you can remove a box, it simplifies things a bit, but that's all.

Hi, CS70,
Thanks for the speedy reply.
I just wondered if a usb connection would have any use with regards to Reaper.

If connected to a PC, the problem is you can only have one audio driver working at a time. So you could select the Benchmark, but then you lose the Edirol and your speaker outputs. So whilst it's slightly convoluted, your current way is about the only way you can use everything at once.

On a Mac, you could create an aggregate device and do it, though some mixtures can apparently be problematical.

Hi Wonks,
Just wondering out of interest if the ADC, having been connected via usb to the PC, could then be toslinked to the DAC and then to the speakers. However, from what you say, as there doesn't seem to be any good reason, in this case, for connecting the usb, I'll give it a
miss.
Thanks for the info.

I'm not sure that would work particularly well. I think you could get the DAC to output what the ADC was sending it, but not anything else sent from your DAW. A quick look at the Audioengine D1 D/A Converter seems to show it to be able to only process one stream of data, with optical taking priority, so it doesn't seem to be able to mix a DAW stereo output over USB and the optical input data at the same time.

Obviously the Edirol is designed to be an input and output device and has the software and mixing capability to do so.

Unless you can find anything else in the manuals that says otherwise, I'd leave things as they are.

Thanks, Wonks,
It's nice to know that what I have has been set up reasonably.
Thanks very much for your help.

Cheers.
