I just got Zapco DC reference 1000.4 and 1000.1 amps. They are works of art. The problem comes when trying to adjust the settings with my computer. I was able to properly set up my 1000.1. However, the 1000.4 is giving me problems. Its acting like din switch 5 is always on and keeps going into firmware update mode. I have tried powering the amp off and on with the same results.
Any suggestions?
