Congratulations on your purchase
of the 880iR 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
880iR and then amplified through the
loudspeaker(s). The standard system
includes the 880iR infrared receiver/
amplifier, LT-71 LightMic
™
transmit-
ter, SR-70 infrared sensor and speaker
package.
The 880iR is a two-channel receiver
amplifier that allows the use of up
to two microphones simultaneously
and up to four 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 pro-
vide 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.
