Entry level is 34 € Thomann, self-powered and two pairs of jacks noon. What else?
Compact, simple, no heating (m'fin it would be the height ..) with an LED indicator for each port and an LED power (see photos I put one immediately sees the config ..)
With reason with me it turns nickel.
No drivers, windows 8 against by not recognized if it is connected to a usb3.0 home port, but is set by changing the USB port, I have two in 2.0 rab. (It's USB 1.1, I'm surprised there is not backward compatibility ..)
I plug it in to a midi keyboard and my MPC 1000 in / out, live in Reason it works impeccable after a few config
The case looks solid, I put 10/10 worry, if you want a small powered USB ports with 2x2 auto twelve o'clock interface that makes his job very well.
I had a bonus two MIDI cables in the box, attention is always fun and gives the interface a fair price.
