Product Description

This Loud Speaker Amplifier (EDMO# LSA400-001) utilizes a highly efficient power supply and a Class-D Amplifier to produce 400 watts RMS (600 watts Peak) of output power with minimal distortion and noise. Designed with the latest technology, this amplifier is ideal for light- and medium-duty helicopters with single and twin turbine engines. The LSA400-001 is more compact and lighter than other comparable amplifier systems, and features flexible options for remote mounting either vertically or horizontally.

In addition, the LSA400 incorporates a "smart" power supply that modifies the amplifier output to meet the output load demand. It is designed for use with the LS300 or LS600 external speaker array and a siren controller as a complete system.

Features

Single differential speaker output capable of driving up to 600 Watts
Built-in protection circuits that keep the amplifier from being damaged, including “output short circuit” and “thermal shutdown”
Four audio inputs consisting of one microphone, two single ended inputs and one differential audio input to provide input source flexibility
Amplifier status annunciators for the protection circuits and user accessible audio input adjustments are displayed externally near the D-Sub connector
Single PA ready output provides a switched ground for remote sensing or displaying of the amplifier ready state
