Products: Military Public Address System: Power amplifier

General description

The equipment is made of lightweight alloy and stainless steel with surfaces treated with high-grade protection against marine environments, in accordance with MIL-C-5541. Mechanical parts are high-resistance and low-weight.

The different modules are mounted to the chassis, which is easily accessible from the outside.

All the components included in the rack are easily accessible for its checking or replacement during maintenance operations.

The connection between the equipment and the ship network is done by means of terminal sockets located in the back part of the chassis.

The Amplifier permits the activation of a general circuit (5MC) that includes the orders group to flight deck, control chambers and associated places.
