NOVA PA/GA - Audio Power Amplifier - GAI

NOVA PA/GA - Audio Power Amplifier - GAI
Class D Audio Power Amplifier
Compact design 3U x 19”
Up to 4 amplifiers in a single modules cage 3U (PA) + 1U (cage)
High efficiency “Class D” 300Wrms Amplifier
Thermal and output overload protections
Speakers line diagnostics function
Serial communication interface (RS485)
Forced cooling by means of dedicated fan activated on temperature threshold
Low frequency 30Hz test, setup and PA diagnostics, line ground leakage detection. A rich set of front
panel LEDs is provided for faults indication (ground leakage, overload, over temperature, amplifier
fault), power on, Vu-meter function. An output transformer insulates the semiconductors power rails
from speaker line increasing safety for critical applications.
