When you need for a powerful sound-field system package for classroom presentation, The IRV-6150 VoiceLink III Sapphire system from Teach Logic is the answer. This system includes two channel infrared wireless receiver, one front panel line input, one rear panel line input, one front panel line output (IR-255), Sapphire transmitter/microphone with Lithium battery (IRT-55), battery charger (BRC-15) and Ceiling dome sensor with 50' plenum-rated cable (ICS-55).
The VoiceLink III system is a two-channel infrared wireless microphone system that can be an addition to any existing sound system whether in a classroom, conference room, banquet room, or district courtroom. The VoiceLink III features a two-channel infrared wireless microphone receiver for the simultaneous use of two wireless microphones: no messy cables and you have total freedom of movement throughout the room. An Aux/Comp input and front panel output for Lesson Capture. The line level output, balanced (phoenix 3-pin) or unbalanced (1/4″ phone), is connected to an existing sound system. It provides excellent vocal quality and reliable connectivity in excess of 30-foot radius to a central ceiling sensor. Interference-free transmission with 100% program material security (infrared will not transmit through walls).
The Sapphire transmitter / microphone (IRT-55) is a stylish new lightweight classroom microphone. So small, it’s hardly noticeable to wear. It can be worn with a lanyard or clipped directly to your neckline collar. In performance, the Sapphire’s vocal clarity is unsurpassed. It boasts high level output, reliable connectivity and exceptional definition. With a built-in breath filter, the Sapphire can function as a pass-around hand mic. It includes Lithium battery.
The ceiling sensor (ICS-55) is the preferred infrared sensor for optimum performance. It comes standard with Forum, Maxim III, Spectrum II, VoiceLink I, VoiceLink Plus, VoiceLink III and VoiceLink IV packages. This unit needs to be installed on the ceiling at least 3′-0″ from the video projector. It comes with a mounting/support bracket and 50 feet of plenum rated cable with RCA connector on each end. The ideal location for the dome sensor would be 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 360° coverage and will minimize the transmission distance for more reliable performance. It collects the infrared transmission signal via 6 large detecting diodes. The sensor is connected to the mixer/amplifier via a plenum rated cable terminated with RCA connectors. The mixer/amplifier supplies the power to the sensor.
The package also includes a plug-in type battery charger (BRC-15) used for IRT-55 transmitter / microphone.
