At the heart of all GAI-Tronics Public Address
Systems is the D550i Class D Power Amplifier.
The D550i is designed for use in GAI-Tronics
high integrity Elemec, NOVA and Advance
public address and alarm systems.
GAI-Tronics
designs
and
manufactures
sophisticated public address and alarm systems
to suit specific markets and applications. The
NOVA system addresses multiple zones,
multiple networks and multiple speech path
applications such as large petrochemical
facilities. Elemecplus addresses self-contained
applications such as platforms and FPSOs.
ADVANCE combines public address with multistation intercom capability.
The field proven D550i amplifier is designed for
performance in a range of applications,
continuous 550W RMS rated outputs for Alarm
Systems to high quality music reproduction.
To reduce the risk of single point failure on AC
systems, the Amplifier has its own internal
rectified
DC
power
supply.
Fault protection and 20 kHz load sensing are
contained within the Amplifier. Load sensing is
easily configured by use of pushbuttons on the
front of each amplifier. This load sensing facility
allows loudspeaker monitoring and automatically
detects changes in the load of the connected
loudspeakers.
Thermostatically controlled fans, integral to each
unit, provide forced air cooling to the output
power devices only during high temperature
operation.
System expansion is easily achieved by simply
adding more amplifiers without the need to
change controller hardware.
