About TeachLogic IRS-8650

Spectrum III

The optimum sound-field system for large rooms
The Spectrum III is the optimum sound-field system with 100 watts of power for large rooms or rooms with high ambient sounds levels. Create a good intelligible learning environment over a large area with up to eight ceiling speakers.

The four auxiliary inputs provide multimedia integration with even distribution of sound for all audio in the classroom. RS-232 wall panel control of the line inputs, Fire alarm connection (AC or DC), remote Teacher Security Alert, teacher priority with instant attenuation of the line levels via Sapphire IRT-60 pendant and Digital Feedback Guard (DFG) and switchable computer anti-hum circuit on computer input. The Spectrum III is a four-channel receiver/amplifier with four auxiliary inputs, page pass through and 4ea 25 watt amplifiers for 100 watts of power.

- SP-2000 Wall Mount Speaker -
The TeachLogic SP-2000 is a full range 2-way compact wall mount/shelf mount speaker, providing low distortion and a smoother frequency response ideal for articulate vocal clarity for more even coverage. The included wall-mount bracket enables the unit to be secured against a wall or other flat surface.

Intended use
Indoor environment, mounted securely against a wall or other flat surface.

- ICS-55 Infrared Dome Sensor -
The ceiling sensor 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 deg. 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.

- IRT-60: Sapphire Handsfree Microphone -

A Jewel of a microphone
The Sapphire is our flagship infrared microphone. Handsfree, lightweight and hardly noticeable when worn on a lanyard or clipped directly to your neckline collar.

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 also function as a pass-around hand mic.

Function
Hold for 1 second to power ON. The "TL" light will glow blue. With a tap on the power button, the mic mutes (blinking blue light) for private conversation - tap again to restore to normal operation. The auxiliary input allows wireless playback of an audio device like a music player. A three-position slide switch provides selection of HIGH, MID or LOW (Normal, -3dB or -6dB) microphone volume level.

Safety
The IRT-60 features: Security Alert, holding down the priority button for five seconds activates a contact closure.

- IRH-35 Handheld Microphone Transmitter -
For use with all TeachLogic infrared sound systems. The handheld microphone/transmitter is primarily used by students for interactive class participation. The ergonomic design renders user comfort and very low handling noise. The unidirectional condenser microphone reproduces excellent vocal quality and the windscreen prevents breath pops. The emitting diodes are located around the top and bottom end of the handle for 360 deg. transmission and assured connectivity throughout the classroom.
