a brief word about infrared IR transmission The IR transmitter transmits directly to the sensor. However; due to the strength of the IR transmitter, the infrared signal will bounce off the walls, ceiling and floor for reception thus providing continuous connectivity throughout the room. Benefit: total freedom of movement within the room with no restriction of orientation.
VoiceLink owner’s manual product description The VoiceLink PLUS is a complete classroom sound system. It includes an infrared wireless microphone/ transmitter receiver and a 20 watt power amplifier. A ceiling sensor senses the infrared signal emitted from the microphone/transmitter and sends the voice signal to the receiver. The receiver can also accept an input from another audio source such as an iPod™, Computer, DVD, or video projector.
VoiceLink plus system The VoiceLink PLUS system is comprised of a microphone/transmitter, either the Sapphire (IRT55) or Handheld (for voice transmission to a ceiling sensor (ICS-55). The sensor sends the signal to the receiver/mixer (IMA-100). The receiver processes the signal and produces an analog signal which is fed to the power amplifier. The output of the amplifier is fed to the speakers (SP-628, SP-628L or SP-2000).
VoiceLink owner’s manual infrared microphone/transmitters The infrared microphone/transmitter is comprised of a microphone input, signal processing circuits and several emitting diodes that transmit the vocal signal to the sensor. The microphone/transmitter can be the Sapphire or Handheld. The rechargeable batteries will provide 6–8 hours of service per charge. Place the microphone/transmitter in the charger for overnight charge and it will be ready for another day’s use.

installation of ICS-55 ceiling sensor The ideal location for the ceiling sensor is in the center of the ceiling. This will provide a clear signal path for the IR transmission from the transmitter to the dome sensor without obstruction. In addition, you will have 360º coverage and will minimize the transmission distance for more reliable performance.
