Q: Do the OP’s actually have to be in sequential order?
A: The Ops do not have to be wired in sequential order to function but I strongly suggest that you keep good records/drawings of the order and placement. Routing the OPs in a random order will make troubleshooting difficult.
Q: I have 2 speaker channels down on an OP, how do I fix this?
A: Unplug the 2 channels in question & test all of the cables on those 2 channels. When there is a short on one channel it will cause the other channel on that amp to shut down (e.g. If channel A has a short on it, it will cause both A and B to shut down….same scenario for channels C&D)
Q: My OP is not showing up online in Sound Manager 2 & the icon is red. What could be causing this issue?
A: Check the cat5e cable with a cable tester & verify all cables in the data run are 100% working. After all cables have been verified, go into Sound Manager 2 and select Restart Poll under the system tab. This will search the system for the OP and will change the status from red to green if located. Also, check the LCD display of the OP to make sure it is still showing its identification number.
Q: My OP is showing double zero, what is the issue?
A: Double zero is an indication that power was connected to the OP while the power supply was live. When a double zero occurs, the OP cannot be used and must be replaced. An OP that displays double zero will also not show up as online in Sound Manager 2.
Q: I noticed my OP has 2 negative screw terminals for both the 48Vdc in and 48Vdc out, does it matter which screw terminal I use?
A: As long as the power pathing is correct (power in/power out), it does not matter which negative screw terminal is used.
Q: The speakers are not working. What’s wrong?
A: Check RJ45 connections on Cat 5e/CAT6
