TeachLogic IRS-8655 Spectrum III Wireless Microphone System, WM-4 Wall Speakers

The TeachLogic IRS-8655 Spectrum III Wireless Microphone System with WM-4 Wall Mount Speakers 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. The addition of a Spectrum III system to your multi-media system will transform your classroom sound system into a totally hands free voice re-enforcement system, resulting in reduced voice fatigue, enhanced student listening and improved student learning. The wireless function permits 360deg. connectivity throughout the classroom regardless of body position or orientation. The system is comprised of an infrared detecting sensors installed in the ceiling. The sensor collects the IR wireless signal from the microphone/ transmitter and sends a composite signal to the receiver. The receiver transforms the composite signal into an analog audio signal which is fed to the multi-media amplifier. The amplifier powers the speakers for even voice reinforcement throughout the room. The microphone / transmitter can be the Sapphire or Handheld. The rechargeable batteries will provide 6 - 8 hours of service per charge. The drop- in charger will recharge the batteries overnight, ready for another day's use. IRT-60 Sapphire Transmitter The Sapphire's vocal clarity is unsurpassed. Its high level output is achieved by the unidirectional (Cardioid) microphone and a unique free air suspension system. With a built-in breath filter, the Sapphire can function as a pass around hand mic. The strategic alignment of the emitting diodes assures reliable connectivity throughout the room without static or drop out. With a tap on the power button, the microphone is muted for private conversation-tap again to restore to normal operation. The auxiliary input allows wireless playback of your iPod through the Sapphire. A three position slide switch provides selection of low, medium or high microphone sensitivity. 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. ICS-55 Ceiling Sensor The ceiling sensor is the preferred infrared sensor for optimum performance. This is the unit that needs to be installed on the ceiling. It comes with a mounting/support bracket and 50 feet of plenum rated cable with an 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 360deg. coverage and will minimize the transmission distance for more reliable performance. It collects the infrared transmission signal via 6 large detecting diodes. An additional sensor and cable can be added for larger rooms. Locate and install the two sensors for optimum IR reception, install an RCA "Y" at the first sensor, run the cable to the second sensor and connect. Maximum distance from Foam to last sensor should not exceed 150'. WM-4 Wall Mount Speakers This is two-way speaker with a 5" woofer and a high frequency Mylar dome tweeter housed in a port tuned enclosure. It gives extended bass response for full rich sound.
