Complete question: I have a Red PS LED indicator illuminated on the front panel of the Main PA, how can I determine which STX GEN II transmitter B+ power supply is faulting?
Answer: Under the DIAGNOSTICS menu screen check each PA Module (PA1, PA2, PA3, PA4, PA5) for a “PA PWR SUPPLY FLT” fault indicator. Another quick method will be to visually check the rear panel of each of the 1kW PA’s and check for missing “AC OK” or “DC OK” LED indicators on each of the 2kW power supplies; under normal condition both LEDs should be lit on green.
