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.

- 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.

- 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.
