I cranked up the volume, and then the channel stopped working. What is going on?
Congratulations! You have just discovered AmpTraXX's built-in overdrive protection. It has just prevented AmpTraXX's amplifier circuit from melting into a small pile of molten goo. There are several ways to bring the Amplifier back out of protection mode.
1. Power-cycle the unit.
2. Issue a Set Filter Type command. If you are using the AmpTraXX application, just change filters.
3. Issue a Reset Amplifier command
