GENERAL DESCRIPTIONSeries HLE and MLE loudspeakers are explosion-proof compression driver/horn assemblies engineered for high-efficiency voice and electronic signal communication in hazardous areas. Drivers, which are protected within a rugged die-cast aluminum housing, are available in 60-watt (HLE Series) and 30-watt (MLE Series) power handling versions. Models with Tsuf- fix include a factory-installed, internally mounted transformer (Note: To meet ULrequirements transformer must be factory installed). All models are equipped with 1.2" conduit access and an adjustable mounting bracket.
