The DIGICALL® SPECTRUM is a unique mobile lab that uses reliable and convenient radio frequency technology to add interaction to the language learning experience. It lets you turn any room into a learning center in a matter of minutes without wiring, special furniture or floor plan limitations. Just choose the subject and location, wheel in the mobile console, distribute the wireless student units, and begin teaching. It's that simple. And you do not have to be a technician to teach with DIGICALL® SPECTRUM, because the controls are easy to understand and simple to operate. Plus, the learning experience becomes more dynamic and encourages participation without inhibition. The results are increased interaction, immediate feedback, and more effective monitoring. The portable system facilitates student learning in the four basic skill groups: listening, speaking, reading, and writing. Students have equal opportunity to listen or speak with privacy, while the instructor can work with individual students without interruption from other students. The system's intercom and recording functions give instant access to student work in progress, offering instructors the ability to work with, monitor, and record individuals, pairs, or groups of students. The instructor can also monitor selected students without their knowledge and provide private instruction as necessary. Secured in the mobile console are lesson sources and a digital control panel with simple buttons and displays to manage all of the wireless audio functions (e.g., lesson source output, intercom, student monitoring/recording, etc.

Each student would be equipped with a multi-channel radio transceiver in a compact case that includes a comfortable lightweight headset with microphone.
