Amplifier | Infrared Microphone Receiver | Audio Mixer

The low cost VoiceLink™ Plus is an essential complement to the interactive whiteboard system. While the whiteboard provides a visual for students, the VoiceLink™ Plus reinforces the instructor’s voice and amplifies media sources. The system features a single channel wireless microphone receiver and two 10-watt amplifiers (20 watts total) to power two or four speakers. When paired with our Sapphire&trade pendant microphone, the teacher’s voice will be clearly heard throughout the room with ease. And the auxiliary input on the front panel allows for the input of a smart phone, computer, or DVD to supplement the instructional program.
