[linux-audio-user] Edirol UA-25: Any issues?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm using an UA-25 and it works plug and play, but having difficulties 
with my gf UA-20 which doesn't get recognized by alsa, unless it is 
switched in 16bit mode.

I can run it at 11.6ms (5.8+5.8) full duplex without any xrun. Lower 
latencies work but I get some xrun every now and then. Anyway I doubt 
you can get a greater bandwith with usb 1 at 24bit.

On jack you get 2 separate inputs and 2 outputs.

I get some hiss when I turn it on. It is not in the recording, you can 
hear it coming from the interface itself, but it goes away after a 
minute or two, when components are warmed up.

I successfully recorded with a phantom powered AKG3000b. Quality is awesome.

I strongly suggest it if you need an usb solution.
