AX24 offers an impressive dynamic range , making it the quietest and most transparent converter on the market.

Full remote controllable via USB or Ethernet.  AX24 is ideally suited for stage box applications or machine room environment, due to the powerful remote control.  The remote control interface is RS-422 nad can be adapted to USB, Ethernet or other data formats providing a very flexible control structure.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
