Is it possible to calibrate 7.5 AND 15 IPS to work properly with DBX on the MSR-16 at the same time? It seems there’s only 1 bias trimmer, and 1 REP lvl for both speeds. I can get either one to work, but then I have to recalibrate to switch speeds, so DBX won’t breathe/act up. I don’t own an MRL tape, but my friend does. I hate to pay/bring him down here every time I wanna switch speeds on a certain project. Any help is greatly appreciated!
