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”.
Spectrum III owner’s manual product description The Spectrum 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.
Spectrum III system The Spectrum III system is comprised of a microphone / transmitter, either the Sapphire (IRT-60), or Handheld (IRH-35) for voice transmission to a ceiling sensor (ICS-55) that sends the signal to the receiver / amplifier (IMA820). The receiver/amplifier processes the signal and produces an analog signal of your voice for output to the sound field speaker system.
Spectrum III 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.
IRT-60 remote control features 1. Moving the priority switch Up/Down will control the volume of the line inputs. 2. A momentary tap of the priority switch will duck down the line inputs 15dB. The receiver front panel power switch changes to a blinking PURPLE. A second tap will restore line input back to normal. 3. Hold in priority switch for 5 seconds closes the contact closure on the Security Alert output. The receivers front panel power switch changes to binking GREEN.
Spectrum III owner’s manual BRC-55 drop-in battery charger This stylish desktop drop-in charging station makes it convenient and easy to recharge both Sapphire Pendant and Handheld Microphones. Charge one IRH-35 handheld transmitter and up to two IRT-60 Sapphire transmitters simultaneously. Charging indicator lights illuminate Red when charging, and Green when fully charged. The “TL” logo illuminates Blue when plugged in.
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.
Spectrum III owner’s manual installation of speakers Two wall mount or ceiling speakers can be powered by the receiver/amplifier. It has two amplifiers (25 watts ea.). One speaker will be connected to each amplifier. Optional: Two additional speakers can be powered by the amplifier. Connect two speakers in parallel. Then bring a cable from each pair to the amplifier. Connect one pair to each amplifier. installing two SP-628 ceiling speakers • Determine the listening area.

Spectrum III owner’s transmitter manual page over-ride/page pass through The page over-ride feature allows you to connect the TeachLogic amplifier to the school paging/intercom system for muting purposes.
fire alarm input blank page The 2 pin orange Phoenix connector labelled Fire Alarm, was designed to provide an emergency mute of the TeachLogic amplifier. When interfaced to the fire alarm relay contact output, all audio devices (microphones, dvd, etc.) will turn SILENT. In the event of a fire, this will help to lower the overall decibel levels and help students and staff hear the audible fire alarm tones/instruction within the classroom. This feature only requires a 5-24 volt AC or DC source.
Spectrum III owner’s transmitter manual RS-232 features blank page The RS-232 feature allows the user to remotely operate the line level media inputs via a convenient wall panel controller. Audio levels very often need to be adjusted when switching from computer audio to DVD players and other audio sources. Such operations as level UP, DOWN and MUTE are easily accomplished via a typical eight button controller, as shown here.
security alert features The security Alert features allows the teacher/ presenter to send a silent wireless electronic signal with a simple press of a button, in the event of an in-classroom security incident. The signal is easily generated by the teacher who is wearing Sapphire wireless pendant microphone. This same microphone transmitter which is used for in-room amplification, has a special button (labelled PRIORITY) on the side for initiating the Security Alert.
