|1. I'm having trouble unplugging the microphones from the Plexer.
At times the microphone connectors can become sticky.
If you have a hard time removing a connector, don't push and pull harder!
This will bend and possibly break the release tab on the connector.
Try pushing the connector back in all the way, and
then very lightly pressing on the release latch. The connector should then release.
Using electronic contact cleaner may also help.
