CONGRATULATIONS!
Congratulations on your purchase of the 850iR Classroom Audio
System! This simple, yet powerful technology provides crystal-clear sound
throughout the classroom, allowing every child to hear every word
every time.
As the teacher speaks into the REDMIKE™ classroom microphone, his
or her voice is transmitted to the 850iR and then amplied through the
loudspeaker(s). The standard system includes the 850iR infrared receiver/
amplier, REDMIKE classroom microphone, SR-70F infrared sensor and
speaker package.
The 850iR is a two-channel receiver amplier 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 REDMIKE is a wireless, pendant-style transmitter. This
two-channel, 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.

PageFirst: Emergency Page Priority
This optional feature interfaces with an independent classroom paging
system. When the page is broadcast, the system is muted, ensuring important
and emergency school-wide messages are never missed.
How it works:
1. PageFirst sensor clip is hung around the lead wires attached to the in-room
paging speaker.
2. The clip is hard-wired to the 850iR.
3. As a page is broadcast, the sensor clip detects the audio signal though
induction and immediately mutes the 850iR.
4. When the page is over, the audio to the 850iR returns to normal.
(For full installation instructions refer to the install sheet included with the
optional PageFirst sensor.)

850iR will mute as an announcement
is made through the school PA
system, ensuring important
messages are never missed.
10. 8-BAND GRAPHIC EQUALIZER: The
sliding controls adjust the levels of
the various audio frequencies. This
allows the installer to properly
equalize the system to produce
optimum sound quality.
11. SENSOR INPUT: The IR sensor cable
connects to either of these two
inputs. Connect additional sensors
to the 850iR to cover large or
