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. The rear panel of the AL2450 has all of the connections and adjustments needed to set up the Atlas Learn system to maximize it efficacy in any size classroom. The AL2450 can support up to three infrared (IR) domes that receive the signal from the wireless microphones and transmit that signal back to the amplifier for playing through the speakers in the classroom. Additionally the AL2450 has equalization adjustments for the microphones to optimize their sound quality, a priority page input that allows the local audio to be overridden when a page is initiated by the administration, and a line output for connection to an external amplifier, recording device, or hearing assistance system based on the classroom requirements. The versatility of the AL2450 receiver / amplifier is what sets it apart from other classroom amplification systems.
