OK a couple things.
1. Set all up, connected my amps and noticed a buzz that is in all channels. I unplugged all source cables (HDMI), BUS connections and all interconnects from the MACH IV (all but one amplifier to see if I had a bad cable or something causing this). To test, I checked that only the Mach IV and one amplifier were plugged into the same, one circuit - nothing else plugged into the MACH IV. Still the buzz. I can hear maybe from 1-2 ft away. It does not change in volume not matter how high I set the gain. It is in all speakers. I cannot hear it from the seating positions around the room and is more annoying than problematic. Doesn't sound like a ground loop. What do you think / suggestions? I like perfection
2. After configuring it all in the software program, I loaded the file again then hit 'SEND ALL' and immediately after, my amps all shut off (all are on turned on my triggers). Even though the triggers were set to ON in the software program, they would not fire up. Even if I turned them on and off in the software program. When I checked the trigger setting by using the front panel controls, I could see it was set to OFF. I turned it on using the front panel controls and it stayed on. This happened to all sources. I had to manually turn the trigger back on for all. Though I was getting feedback using the computer program and I had the triggers set to ON, they were not 'ON' in the MACH IV. Might be a software bug.
3. Relatedly, when firing up the software program, I hit UPDATE ALL and then hit the LOAD FILE button. After I load the file, everything is loaded and looks good. But why does the SEND ALL button turn YELLOW after hitting LOAD? I never hit the SEND ALL button after loading settings but did so one time and I lost trigger commands from the software program. What is that all about?
4. Also, Joel had told me the command to have the OSD turn off after a certain time period. How do you do that again??
All is loaded, levels set, but with the buzz thing I ran out of time to test the sonics tonight. But I am ready to go!!
