This came up surplus from the BBC radio remotes division and i figured it would make a useful audio tool for the studio.
Theres 5 DI / Line amps with gain and 2 outputs each starting on the left side.
The right side has a stereo mic pre with secondary sends as well!
It's designed to run on AC or battery but required 240 volts AC ( UK ) to run.
I replaced the AC transformer with one that would deliver the correct secondary voltage from a US line and everything else worked!
