Nice PW 5B preamp, i gotta get me one of those.
I've used my 828 for many years being fed from the 6 channel inserts from my Mackie 1402. If you only go to first click, they are pre eq and fader outs (essentially no frill mic pre with phantom; perfect for digital recording. Trim and low fq rolloff are the only things in use) You can still live monitor the channels to the main outs and eq as you would normally use the mixer.
So if you stumble upon an old Mackie mixer, it makes a great front end for this ada.
