The SPA amplifiers were specifically developed to meet the requirements of EN 60849 for safety
installations. Each amplifier module is fitted with its own 220 VAC/24 VDC power supply for increased
system reliability. To avoid handling errors, the volume output is set using the potentiometer located at
the back of the apparatus. In addition to standard protection via fuses, SPA amplifiers also have
electronic and thermal protection to protect them from all potential hazards.
A fan provides forced cooling for the final power shelves and internal parts of the apparatus. It starts up
automatically when the temperature reaches a certain threshold, and stops when it returns to normal
values.
Four LEDs display the status of each amplifier: AC or DC power supply, Line Overload and Temperature
overload.
Furthermore, a three LEDs Vu-Meter indicates the presence and level of audio signal.
