Old M14 works with iPad

Just thought some people might be interested to know that the old (ancient) M14 can be used as an audio interface for the iPad. The XLR inputs on the back don’t work but the line in at the front does. It can take a guitar/line input or a battery power mic, ie, one with its own phantom power. I’m using an old Rode NT3. And, of course, the main outputs on the back do work, as does the headphone out at the front.
I’m really surprised - and relieved as I was p…ssed off that a good piece of hardware just wouldn’t work with recent Windows systems. I use a powered USB (2) hub and a cheap substitute for the Apple connection kit (which I do understand may break down pretty soon - but it does work).
