Just wanted to reach out to a larger audience about an issue I am having.
We installed a ZC1 at a gym and it is automatically raising and lowering the volume without being touched. You can watch it jump up and down in the program when on line, and obviously you can hear the volume going up and down. Tech support suggested a couple of things. One was to pull it out and plug it directly into the Zone pro, the other was the cable could be getting RF interference. Plugged the ZC1 into the zone pro, actually the BOB, and the volume was steady. This led me to believe it was a cable issue. Reran the cable using Shielded Cat 5e, same problem. Originally Cat6 was used.
After calling tech support again, they want me to check the voltage on pin 1 and 8 and also try a new program because what I have may be corrupted??? I have another ZC1 in a different room and it works fine.
So, anyone have an issue like this? Can SPL affect the signal travel. We are dealing with SPL's of just under 100. 6400 watts for two JBL CBT1000+1000E. I just can't believe I have two bad cable runs. They are clean and away from AC, fans and normal things we try to avoid. Cable run is roughly 200' at 20' in the air through a roofing deck. Zone Pro 640M, BOB and 2 ZC1's
Any help suggestions or trouble shooting ideas would be appreciated.
