It's unfortunate but true - a lesson might be lost on students if they have trouble hearing the instructor. With the Trulink Audio Amplifier for classrooms students will remain attentive and better informed during class - no more disengaged learners.

With maximum sound amplification, this cutting-edge system ensures consistent levels of audio through the classroom whether from the instructor, video or other multimedia source. Connects easily to classroom A/V equipment such asprojectors, microphones, laptops or DVD players and ensures that each student has a quality learning experience. The Trulink Audio Amplifier is powerful enough to overcome background noise, poor room acoustics and even mild hearing loss in students.
