• TV/VCR: Accepts stereo signal
from TV/VCR via RCA cable.
• CD/DVD: Accepts stereo signal
from CD/DVD player via RCA cable.
8. 800iX INPUT: This input jack allows
for interface with the LightSPEED
800iX wireless microphone system,
which adds up to additional two
microphone channels.
9. PAGING INPUT and ADJ:
When the optional PageFirst sensor
is connected to this input, the audio
being amplified through the 850iR
will mute as an announcement is
made through the school PA
system, ensuring important
messages are never missed.

0. 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.
1. SENSOR INPUT: The IR sensor cable
connects to either of these two
inputs. Connect additional sensors
to the 850iR to cover large or odd-
shaped classrooms.
2. SENSOR SHORT: This LED glows red
when there is a short in the sensor
or cable.

2. Determine the size and type of audio input
jack on the device as many manufacturers’
products differ in connector size and
shape. The LightSPEED LES-370 Personal
FM System requires a 3.5 mm to 3.5 mm
patch cable (part# CA-MMC3535, not included).
5. With the 850iR and ALD turned on, speak into the
LightMic and slowly adjust the corresponding “ADJ”
volume control until the appropriate audio level is
attained in the ALD’s receiver headphones.
1. Turn the ALD (Assistive Listening Device) volume control on
the back panel all the way down (fully counterclockwise).
3. Connect a patch cable from the ALD’s microphone
jack or AUX input to the 3.5 mm audio jack labeled
“ALD OUT” on the back of the 850iR.
4. Adjust the volume control on the ALD’s receiver
to maximum output. NOTE! This is to set the
maximum allowable signal from the 850iR.
