AL2430 Pendant IR Transmitter
The versatile and ergonomic AL 2430 pendant / handheld microphone transmitter
allows both teachers and students freedom of movement without bulky electronics or
cumbersome wires. The dual mode transmit ter allows teachers to control microphone
volume, overall system volume and mute settings via side mounted soft touch controls.
In addition, when “PANIC” and “MODE” controls are pressed simultaneously for 3
seconds a contact closure is triggered on the AL 2430 receiver. This contact closure
may be integrated with most any intercom or IP based notification system to signal an
emergency condition in the classroom. When transmitter is configured for “student”
mode operation, all controls are bypassed restricting the device’s functionality for use
as a wireless microphone only.

The compact, ergonomically designed AL2430 receiver/amplifier provides intuitive control of all system
components, visual indication of system status and interface for “panic” condition feedback to secondary
securit y systems. With inputs included to accommodate most any multimedia source, dedicated AV
systems are no longer needed saving valuable space in the classroom.

Bring all your students to the head of the class…
The Atlas Learn AL 2430 system is an in-classroom sound reinforcement solution designed for use in K-12 and higher education
facilities or where a room constrained public address system is required. This complete audio enrichment package consists of
amplifier / receiver, wireless microphones, and docking station designed to allow the teacher and students to walk freely around the
room with the infrared microphones/system control units and project their voices through installed speakers.
Classrooms equipped with sound reinforcement benefit teachers, students, and the education system as a whole. With even sound
distribution, lessons are easily heard no matter where students are seated. Attention and concentration are raised, especially
in the back of the room, through this added involvement. Teachers no longer strain their voice and they can easily integrate with
multimedia teaching tools such as computers and DVD players by controlling audio from a single source. And with priorit y paging
and emergency notification to inform another location of the need for outside assistance, Atlas Learn fulfills the needs of any
education facility.
