Smart Research UP4 

Four Channel Universal Mic/Line Preamps.

Software 'Front Panel' application to control the UP4 from a PC is version U4_05C.exe. Macintosh version for OSX is: UP4 v05C. These only need the file 'Factory' to be in the same folder to run, so no install is necessary. Simply drag the folder to your hard disk. They can be run as 'Demos' on their own, without connecting to a UP4, and so may be of informative value to show the functions available. Please feel free to distribute them.
