Overview
The LES 780iR Infrared Classroom
Amplification System includes the LES
780iR receiver/amplifier, LT-70 Light Mic™
microphone/transmitter, SR-70 infrared
sensor and speaker package. This system
allows teachers to speak at a normal conver-
sational level while being heard clearly by
every student in the classroom.
The LES 780iR is a two-channel receiver/
amplifier that allows the use of two micro-
phones and up to four audio input sources.
In addition, up to six speakers can be con-
nected to the LES 780iR, ensuring that no
matter the size or shape of the room, every
child hears every word—every time.
The LT-70 LightMic is a wireless, pendent-
style microphone/transmitter. This two-
channel, rechargeable microphone
is clipped to a lavaliere cord and worn
around the neck or held like a
