Sigcom’s AMH Series signals are high output continuous duty amplified speakers for industrial signaling applications in hazardous areas. AMH Series signals draw extremely low power from the audio system while producing audio reproduction up to 107 dBA. Each AMH Series signal features a rugged speaker cone and a projector built with spun aluminum. The amplification, power management, and other internal circuitry are built into a rugged die cast aluminum housing which is sealed with powder coat paint and includes dust and moisture proof gaskets.
