Decent AES I/O expansion for ULN-8 Digital Converters

Decent AES I/O expansion for ULN-8

Hey All,

Loving my ULN-8 and 8 inputs gets me by 98% of the time. But every once in a while I want a few more channels (think toms, percussion, etc..). Don't need the greatest conversion but the ULN-8 only takes AES/EBU for its digital inputs.

Can't seem to find a sub $1500 answer for this and for the amount of use it will get I only wish I could make the Behringer ADA8000 work (I feel dirty even saying it)........ Currently have an old Focusrite 428 hooked up but really would like to sell that one (I have other pres that are more exciting at this time)

So, any more like $500 solution... used is fine.......

All I found was
Aurora 8
RME ADI-QS (yikes!)
and a weird AJA ADA4 (right price for 4 channels but who knows anything about this one)

Thanks!

What about an Apogee Rosetta 800? Doesn't that have AES? If you only needed AD, I think the AD16X would work also.

Presonus Digimax 48K here. Works fine. The 96k version is easily had for your budget.

Apogee stuff is great but pricey
Presonus is all ADAT outputs as far as I can tell
Mackie 800r..... now that will work! Now I have to find one.......
For 2 channels there is also a Behringer SRC2496 -- $170 new......

THANKS!

Audient ASP008. 8 fast preamps with good A/D conversion built in. It's got both ADAT, AES/EBU and Analog outputs, which makes it usable when you want to split your signal to FOH or other stuff.

I just saw an AD16X go for $1500. I'm assuming a used Rosetta 800 can be had for around $1200 these days. Why hook up a Behringer to a ULN8?

Regarding the Presonus, this is incorrect. The old (i.e. made in the US, good) Digimax 48 and 96ks have AES output. I use one with a ULN-8 which I picked up used for $400 or so.

Thanks Syntax for clearing that up........

So two days ago I decided to keep my ISA428 with digital card (just got the digital card a few months ago).......
Got everything working and casually touched the back of the 428..... to my surprise I would say the case is at about 80degreesC !!! Being an electronics guy I investigated. Although the pre works perfectly there is a serious heat problem with this design. So off to ebay she goes.........

From the input here I think I will be hunting for a combined pre/converter unit--
either -- Presonus digimax, the Mackie 800r or the audient..........

Still welcome other ideas but this is it so far.........

Thanks all!!

Hi, how do you tell if the unit is made in the US? Also, can you please clarify the connection with the ULN8 DB25 connector and the Digimaxes?

Sorry if that's a bonehead question, I'm still getting my head around the AES/EBU stereo channel protocol vs. the ULN8 "8 channels AES digital I/O on DB25 / Single wire mode for full 8 channels at 44.1-192KHz operation" definition.

Thanks!

<DELETED BY MODERATOR> I found the dsub/aes connector and assume only USA made units had dsub.

My Digimax (original 48kHz) uses the presonus AES cable and simply goes DB25 on ULN8 to DB9 (I think) on the presonus. Works fine.

My buddy just picked one up for $350. This thing really flies under the radar.
