Need some basic audio interface for PC/MAC that works with Kronos Optical SPDIF Read On

Here's the story,

I needed an audio interface for my iPad as I don't like plugging and unplugging cables from my other interface. I also wanted to use my Kronos Spdif inputs as I don't use usb for audio.

So I eventually ended up finding this Product : Behringer UCA222

https://www.amazon.com/Behringer-U-Control-Ultra-Low-Interface-Software/dp/B0023BYDHK/ref=cm_cr_arp_d_product_top?ie=UTF8

It's 16 bit, only upto 48k, etc, but for the price I decided to give it a shot, hell its cheaper than some cables I have. So, It arrived Plugged into computer. Downloaded ASIO Drivers from a third party, Plugged an optical toslink from its output into kronos input, routed them to L/R.

IT WORKED !!! Smile

++ Has worked with anything I threw at it,
iPad,PC,Laptop and even my Android Phone (Can play your backing tracks along with the other two Kronos analog inputs free for anything.)

So at Sample buffer of 128 I am getting no pops running Diva in Divine mode on my main PC that I built in 2011.

Pros :
+It's tiny, about same size as Cigarette pack.
+Works outta the box!!
+Works with Kronos SPDIF (YAY !!)
+44.1k,48K Samplerate
+Decent latency
+Has Standard RCA inputs

Cons:
- 16 bit only,Not an issue if you do proper gain staging)
- Behringer stopped distributing ASIO drivers and recommends ASIO 4 ALL Drivers, but I found them (original asio driver) online nevertheless.
- No Hardware input monitoring - i.e does not work in standalone mode.

at the price it's even worth buying as basic headphone amplifier or throw in as a backup audio device.

If you are looking for a cheap method to bring some external audio (VST/iPad,Phone) into Kronos along using mostly the unused SPDIF Optical ports, this is something that does work beautifully Smile

It costed me around USD 38.00. Well Worth every Cent!

Sounds cool. Do you think this would work to fix audio crackling, when running iPad synths apps back into the Kronos? That was a big issue when I tried running the audio of the iPad back into the Kronos via USB.

I haven't had any issue yet, but I am using an iPad pro. It definitely should take care of things from Kronos end.

I ran Model 15, Arp odyssey and Nave simultaneously without any sound artifacts.

Very cool. I shall have to try it. I have an iPad Pro also. The 9.7. The only issue would be, that the camera adapter kit, that I use to control the apps via midi (as a controller) would be taken up.
Thanks

I use a powered USB 3 hub for that. Puts much less load on iPad and increases battery life by a ton.

I already have the new camera kit adapter where you can plug in the charger also. Should I still go with a powered hub or would one of these suffice?

Or one of these?

I have two of these and they work great.

There is a Youtube video where someone mods one to be a better quality DAC.

I am confused. Does this also work with the iPad as an audio interface?
If so, then it is core audio compliant?

Update : So it uses 4558 (though not the same ones like the JRC4558's in vintage tube screamers) op-amps for Headphone and lines. They are cheap op-amps and surely can be improved / replaced with better ones from NEC or AD, even TI TLO72's might be a bit better.
Although I am Going to use SPDIF mainly so not much use to me, Just posting for anyone interested.

The 4558 line is fine. I mean you can try and get Burr Brown chips, but it probably wouldn't make that much difference.
