TheLSA400-001Loud Speaker Amplifier 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.
