Congratulations on your purchase of the 850iR Classroom Amplifica- tion System! This simple, yet power- ful technology provides crystal-clear sound throughout the classroom, allowing every child to hear every word every time.

As the teacher speaks into the LightMic pendant-style transmitter, his or her voice is transmitted to the 850iR and then amplified through the loudspeaker(s). The standard system includes the 850iR infrared receiver/ amplifier, LT-71 LightMic™ transmit- ter, SR-70 infrared sensor and speaker package.

The 850iR is a two-channel receiver amplifier that allows the use of up to two microphones simultaneously and up to three additional audio input sources (such as TV, VCR, DVD, CD, MP3, etc.). In addition, LightSPEED offers various speaker options that are included with your system to provide optimal sound in rooms of all shapes and sizes.

The LT-71 LightMic is a wireless, pen- dant-style transmitter. This two-chan- nel, rechargeable unit is clipped to a lavaliere cord and worn around the neck for teacher use, or it can be used like a standard handheld microphone for the students to pass around when speaking.
