TECT LED. If it comes on immediately, a fault has occurred within the amp and it will need to
be returned to the factory for repair. If the LED does not come on, the amp should operate
normally.
PROBLEM:
PMA MANAGER CANNOT ESTABLISH CONNECTION TO THE AMPLIFIER
While every effort was made to make PMA Manager and the PMA Amplifiers robust and as bullet-
proof as possible, modern day PC’s are complicated devices with everyone’s PC being comprised
of a vast variety of differing hardware and software components. Software and hardware drivers
can interfere with one another and cause the system to act in unpredictable ways.
CAUSE 1 : PMA MANAGER IS INCORRECTLY IDENTIFYING ANOTHER HARDWARE DEVICE AT-
TACHED TO THE COMPUTER AS A PMA AMPLIFIER
This happens when the third party device that uses the same USB hardware interface as the
PMA Amplifier (and therefore the same driver) is connected to the PC before the PMA Ampli-
fier. To Windows, these devices look the same.
REMEDY :
While programming PMA Amplifiers, disconnect all other USB devices from your PC. This will
allow PMA Manager to easily identify and connect to the amp.
CAUSE 2 : WINDOWS HAS NOT LOADED THE CORRECT USB DEVICE DRIVER FOR THE PMA AMP
The first time you connect a PMA amplifier to your PC, Windows must locate and install USB
drivers for the PMA unit into your operating system. Normally, this will require access to the
internet so that Windows can find the required files and copy them to PC hard disk.
REMEDY :
If you have not connected a PMA amplifier to your PC when an internet connection is active
you will need to do so. It doesn’t matter which model or which particular PMA chassis you are
connected to do this, any PMA amplifier will do.
