CONGRATULATIONS!
Congratulations on your purchase of the 800iX Infrared Wireless
Microphone System! This simple, yet powerful technology provides the
ability to add the benets of infrared microphone technology to existing
ampliers or to Lightspeed’s popular 880iR and 850iR systems to create
up to a four-channel solution for the classroom.
The 800iX is a two-channel receiver that allows the use of up to two
additional microphones simultaneously. A standard IR sensor can provide
high quality reception in rooms up to 1600 square feet. By connecting
additional infrared sensors to the receiver, the coverage area can be
expanded to provide optimal reception in varying room sizes
and congurations.
The REDMIKE is a two-channel, rechargeable classroom microphone that
is clipped to a lavaliere cord and worn around the neck for teacher use, or
it can be used as a standard handheld microphone for students to pass
around when speaking.

2. LOCATION OF THE RECEIVER
800iX User Manual
• Before running wires to the 800iX
or plugging in, nd a suitable,
stable location for the amplier.
Ideally, the teacher should have
ready access and an electrical
outlet should be within
six feet. The best
possible location
for the 800iX is in a
media cabinet with
any existing audio/
video equipment.
• Wires should be routed back directly to the
amplier, so select a location that is free from
obstructions that may make routing wire
difcult.
(Example: placing the 800iX near
a whiteboard or bulletin board
would require the wiring
to be run an extra
distance in
order to reach
the amplier.)
Best
• A good location would be on any
stable bookcase or shelf within
6 feet of an electrical outlet. The
optional Lightspeed wall shelf (part
#AC-800WB) is specically designed
to support the 800iX.

USING THE REDMIKE TO AMPLIFY EXTERNAL AUDIO EQUIPMENT
The REDMIKE includes a 3.5mm audio input jack to connect to an audio source like
a laptop or MP3 player. The REDMIKE will transmit the audio signal to be played
through the system.
1. If your system includes two
REDMIKEs, use the student
microphone (already set to
Channel B). NOTE: This feature
works on both channels but we recommend using Channel B so the teacher’s
volume on the CH A does not have to be adjusted. REMEMBER: It’s easy to
determine which REDMIKE is set to Channel B by speaking into the mic and
watching which set of LED’s glow on the front panel of the 800iX.
