The AL2450 coordinates all of the functions of the Atlas Learn system and brings all of the features together for a single unit control center. The AL2450 is loaded with features that not only enhance the quality of audio generated by the system but that are also easy to use and understand. Physically the AL2450 is very compact making it easy to install on a desk or in a small rack. The unit features Atlas Sound’s patent pending through chassis design which allows the unit to be mounted to a pole in conjunction with a projector or other equipment if security is a concern. The front of the unit features a main power switch as well as volume controls for two microphones (A and B), as well as four other external audio sources like Computer, TV, CD, or Auxiliary audio.
