TeachLogic IRV-1150 Voice Link I Infrared Wireless Microphone System

The TeachLogic IRV-1150 Voice Link I Infrared Wireless Microphone System includes the IRT-55 Sapphire Transmitter Microphone, IR-100 Receiver, ICS-55 Ceiling Sensor, BRC-15 Drop-In Charger for the microphone, and 50’ plenum rated cable. The handheld microphone enables voice transmission to the ceiling sensor that sends the signal to the receiver. The receiver processes the signal and produces an analog signal of your voice for input to an amplified sound system (not included).

This infrared wireless microphone system can be a supplement to an existing multimedia system to expand it’s utilization to provide voice reinforcement. The wireless function permits 360° connectivity throughout the classroom regardless of body position or orientation.

The VoiceLink I system will expand your multi-media sound system to include voice reinforcement via an infrared wireless microphone. The VoiceLink I is a preamp-only receiver and is designed to be plugged into an existing power amplifier or the input of a multi-media sound system. 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 an iPod™, computer, or DVD to supplement the instructional program.
