Design Features
The LSA800-001 has a two differential speaker outputs, each capable of driving 400 watts RMS (800
watts Peak) into 3 Ohm loads.
The LSA800-001 has a number of built in protection circuits that keep the amplifier from being damaged,
including
Output Short Circuit
and
Thermal Shutdown
which minimize the possibility of damage to the
speaker output stage.
The LSA800-001 has four audio inputs consisting of one microphone, two single ended inputs and one
differential audio input to provide input source flexibility. Each input has a field adjustable gain level to
optimize speaker output power for various input signal levels.
The amplifier status annunciators for the protection circuits and user accessible audio input adjustments
are displayed externally near the D-Sub connectors .
See Section 2.0 for further details on the Audio Input Adjustments and Section 3.0 for Status
Annunciators.
There are two Remote On/Off inputs that provide the ability for low current switched high or switched low
remote activation of the amplifier if being turned on remotely from a siren controller.
A single PA Ready output provides a switched ground for remote sensing or displaying of the amplifier
ready state.
