Introduction
AUDIO ENHANCEMENT has been creating
technologically advanced products that
exceed expectations for over 25 years.
Designed by caring professionals for those
who teach the future leaders of America,
your infrared (IR) classroom amplication
system is an important step in improving the
learning environment.
Your infrared classroom system represents
a breakthrough in classroom amplication.
It assures you the clarity and interference
free performance you expect, even with
large numbers of systems at use in the same
building.
Please read through this manual before
installing and using your IR system, and refer
to it often. Our sta is available to answer
any questions that may arise at 1-800-383-
9362.
When asked to rank the importance of nine dierent types of equipment used in classroom instruction,
• 34% of teachers in general education ranked classroom amplication most important. This
ranks it above the overhead projector, which came in second at 18%, and the computer at 16%.
• 75% of a child’s school day is spent engaged in listening activities.
• 90% of a young child’s knowledge is attributed to incidental reception of a conversation around

“F” Function
Setting the Function Channel on
the Teacher microphone
1. Remove the battery cover of the
microphone. Press down on the
battery cover with both thumbs and
pull down, in the direction of the arrow.
2. Set the transmitting channel and assign
function F1 or F2 with the channel
select control. To set the transmitting
channels and assign functions to the
function button, use the small channel
setting screwdriver (microphone’s
accessory) to turn the channel select
switch until it clicks into place.
3. Set the channel selector switch to the
desired channel. F2 is the Security Alert
function and F1 is the momentary
activation function. For normal use,
set the switch to CH1 in the F2 (white
background) area of the switch.

Amplier Function Output
Connections
Function Outputs are opto-isolated and
are the equivalent of an Open Collector
NPN transistor that can handle a maximum
of 30 V DC at 20 mA. The CNT terminal is
the collector and the COM is the emitter.
Function Activation
F1 Function - The F1 Function activation provides for a momentary (300 ms) activation of the
F1 CNT and COM terminals every time the Function button is pressed. If the Function button is
pressed and held in F1 Function, it will provide a 300 ms activation every 600 ms. A 300 ms ON
followed by a 300 ms OFF, repeating until the Function button is released.
F2 Function - The F2 Function activation will cause the F2, CNT and COM terminals to activate
and remain activated until the receiver is powered OFF or the receiver does not receive an F2
signal from the microphone for three minutes.
The F2 transmission from a microphone can only be terminated by turning the microphone
power OFF.
