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. “What’s said in the room, stays in the room”.
VoiceLink III owner’s manual product description The VoiceLink III is an infrared wireless microphone system that can be added to any sound system. It can be a supplement to an existing multi-media system to expand it's utilization to provide voice reinforcement.
VoiceLink III system The VoiceLink III system is comprised of a microphone / transmitter, either the Sapphire (IRT55), or Handheld (IRH-35) for voice transmission to a ceiling sensor (ICS-55) that sends the signal to the receiver / mixer (IR-255). The receiver processes the signal and produces an analog signal of your voice for input to an amplified sound system.

Location of the sensor and routing of the sensor cable is a more critical issue. location and Installation of receiver Since the VoiceLink III is a supplement to an existing power amplifier system, you will want to locate the receiver near the power amplifier to minimize audio cable length from receiver to sound system.
VoiceLink III owner’s manual 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.
