INTRODUCTION
PX series of power amplifiers are equipped with AFS (Auto Fault Sensor) which generate pilot tones internally and automatically diagnose and detect any faulty condition that may occur at the output end. Pilot tones are generated at intervals to avoid straining the power packs, and this shall prolong the life span of the units.
FEATURES
 |
Incorporating Auto Fault Sensing (AFS) circuitry for self monitoring of its output |
|
Pilot tone switchable for normal operation without AFS |
|
Interval PT generation to avoid continuous loading of the amplifier |
|
Thermal protection by muting input signal (typically 85º at heat sink) |
|
Temperature dependent dual speed cooling fan |
|
Manual reset circuit breaker for AC mains and DC input |
|
Balanced input signal with gain control and selectable grounding option |
|
AC and DC operation for uniterrupted operation during power failure |
