CONGRATULATIONS!
Congratulations on your purchase of the REDCAT™ All-in-One
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 REDCAT and then amplied through the
built-in at panel speaker. The REDCAT system is fully integrated and
includes a receiver/amplier, infrared sensors, at panel speaker and the
REDMIKE classroom microphone.
The REDCAT is a two-channel receiver/amplier that allows the use of up
to two microphones simultaneously and two audio input sources such as
TV, VCR, DVD, CD, MP3, etc.
The REDMIKE is an infrared classroom microphone. This pendant-style
microphone is clipped to a lavaliere cord and worn around the teacher’s
neck. It can also be used as a standard handheld microphone for student
interaction and class participation.

OUTPUT TO ASSISTIVE LISTENING DEVICE (ALD)
1. Turn the ALD (Assistive
Listening Device) volume
control all way the down.
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 3.5mm
to 3.5mm patch cable
(part# CA-MMC3535, not
included).
3. Connect a patch
cable from the ALD’s
microphone jack or AUX
input to the 3.5mm
audio jack labeled
“ALD OUT” on the side
of the REDCAT.
4. Adjust the volume
control on the ALD’s
receiver to maximum
output. NOTE: This is
to set the maximum
allowable signal from
the REDCAT.
5. With the REDCAT and
ALD turned on, speak
into the REDMIKE and
slowly adjust the ALD
volume control until the
appropriate audio level is
attained in the ALD’s
receiver headphones.

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.
LT-71
The optional LT-71 can also amplify external
audio. Simply plug the 3.5mm patch cable
from the audio source into the input labeled
“AUX IN” and adjust the volume of the
source to the desired sound level.
Helpful Hint
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 side of the REDCAT.
2. Plug your laptop,
MP3 player or other
audio source into
the input on the
REDMIKE labeled
“INPUT” using a
3.5mm patch cable.

TROUBLESHOOTING GUIDE
If you review these instructions and still have questions, write down the serial
number and model number of your system and call Lightspeed Technical Services at
800.732.8999, 5 a.m. – 5 p.m. PST.
NOTE: Most problems are directly related to low battery power. Please run through the
“Battery Check” items rst. For remaining troubleshooting, use known good, fully-charged
batteries.
Battery Check
• Conrm batteries are charged
each night.
• Conrm proper batteries are used.
The REDMIKE requires the Lightspeed
BA-NH2A27 rechargeable sensing
battery for proper charging. The LT-71
& HM-70 require NiMH AA rechargeable
batteries.
• Make sure the REDMIKE is turned off
while charging so that it will attain a full
charge. Full charge will last eight hours.
• Inspect the battery contacts. Clean and
adjust if necessary.
Hearing Static
• Ensure sensor is in optimum location
(refer to sensor placement in manual).
A single sensor will cover a 1600 sq. ft.
enclosed classroom.
• Ensure that no other REDMIKE/LT71/
HM70 is operating on the same channel.
• If an external microphone is in use,
try another REDMIKE that is known to
be working (if available) to isolate the
problem. If static persists with “known
good” microphone, the REDMIKE input
jack will need service.
Low Volume or Feedback
•
Ensure microphone is positioned
appropriately, just below the collar
bone.
• Check volume level on the amplier. If
the volume is too high, feedback WILL
occur. Adjust accordingly.
No Sound From Speaker
• Turn the REDCAT on. Conrm that the
POWER light located on the front panel
switch is on.
• Conrm signal is being received at
the REDCAT. The IR signal light will
be GREEN indicating a signal is being
received.
• Conrm that REDMIKE is turned on.
There will be a BLUE LED on
the microphone to indicate it is
powered on.

around your neck. Adjust the neck
strap so the top of the microphone
rests just below your collarbone.
Place the REDMIKE back into the
charging cradle to recharge at the
end of the day.

TIPS ON CLASSROOM AUDIO
Avoid wearing jewelry that may rub or bump against
the microphone.
Turn the REDMIKE off during private conversations with a student,
parent, or other classroom visitor. You can also cover the LED
lens on the REDMIKE to block the signal.
Recharge batteries each night. When recharged nightly, operating
time (actual usage) for the microphones will last through a typical
school day.

Speak
in a natural voice. A normal conversational speech level
will provide an adequate signal. It is not necessary to increase
the intensity of your voice—the audio system provides
adequate amplication (approximately 5 – 10 dB) above
ambient room noises.

will handle all your repair/replacement needs.
