electrical circuit between a power amplifier channel and its respective speakers. The LEDs, indicate a complete circuit
from the respective power amplifier channel to the speakers and back when the power amplifier is in operation. An
active LED indicates that the power amplifier channel, system driver board, speaker wires, and speaker(s) are
functioning when a warning signal tone or public address mode is active. Speakers < 60 Watts may not indicate
correctly.
In the public address mode of operation, each appropriate power amplifier channel(s) increases its amplification output
by an additional 25% to compensate for the differential in power between voice audio signals and siren warning signals.
This increase in amplification assists in providing voice broadcasting at warning signal tone ranges.
