VoiceLink™ I Teacher Voice Lift System Description

The VoiceLink™ I allows you to add a wireless microphone to your existing classroom sound amplification system. Simply connect the output port of the VoiceLink™ I  to an audio input port of the existing classroom system. A ceiling sensor connects to the VoiceLink™ I so that the microphone transmission is sent through the VoiceLink™ I  into the audio system and out the speakers.

With a VoiceLink™ I infrared wireless microphone system, the teacher’s voice will be clearly heard throughout the room with ease. And the auxiliary input on the front panel allows the input of a smart phone, computer, or DVD to supplement the instructional program.
