SAFETY SYMBOLS
Labeling on products and the
Installation Instructions &
User Manual
may use safety related graphical symbols
as shown below to note safety requirements.
Lightning Bolt:
The lightning flash with
arrowhead symbol, within an equilateral triangle,
WARNING symbol, is intended to alert the user to
the presence of un-insulated
dangerous voltage
within the product’s enclosure that may be
sufficient in magnitude to constitute a risk of
electric shock to persons or domestic animals.
Exclamation Point:
The exclamation point
within an equilateral triangle, CAUTION symbol,
is in-tended to alert the user to the presence of
important operating and maintenance (servicing)
instructions, or a hazard that can damage equip-

until you have understood the hazardous condition and
have taken appropriate steps.
INTRODUCTION
The LC372SR is a classroom sound reinforcement module designed for use in the IED LANcom SCS. The LC372SR
utilizes wireless infrared microphones with an integrated receiver-audio mixer/amplifier to provide audio amplification
in small to medium-sized applications like classrooms, libraries, lecture halls, small gymnasiums and auditoriums. The
LC372SR has a line-level output to feed external devices such as hearing assistant systems, audio recorders or larger
power amplifiers if it is used in a larger room such as a gymnasium. The Sound Reinforcement Module comes complete
with 30 watt amplifier/receiver, infrared microphone, infrared sensor and charging station. It is controlled using a web-
based interface for simplified configuration and use. It features no external knobs or switches to eliminate tampering or
inadvertent system changes. All adjustments are made through IED’s LANcom SCS Software (LC300SWP) that allows
teachers and end users to easily manage program source selection, individual component volume, muting and other
functions after the installing contractor sets levels for emergency messages, bells and paging audio.
Classroom sound reinforcement benefits teachers, guest lecturers, students and the education system as a whole. With
even sound distribution, lessons are heard no matter where students are seated. Attention and concentration are raised,
especially in the back of the room, through this added involvement. Teachers no longer strain their voice when using a
wireless microphone and they can easily integrate with multimedia teaching tools such as computers and DVD players
by controlling audio from a single source. With intercom, priority paging and emergency notification to inform another
location of the need for outside assistance, IED LANcom SCS fulfills the needs of any education or large multifaceted
facility.
The LANcom SCS is a full system solution to meet the needs of all school districts. The flexible and wide array of prod-
ucts is designed to provide all the audio support needed no matter the application.
The integrated receiver of the LC372SR is a 30W amplifier with a 25V speaker line. It features two (2) RJ45 connectors
for use with LC11CS or LC12DCS wall plate call switches and LC372M remote intercom microphone. These standard
call switches provide four logic input functions as normal call, emergency call, lockdown acknowledge, and contractor
defined (i.e. CCTV or relay control). Four (4) relays are included; Relays 1 and 2 are for analog clock and time display
synchronization and two (2) are for contractor defined relay for ancillary system integration via Phoenix/Euro block con-
nector.
The Sound Reinforcement Module also features four (4) auxiliary inputs; one (1) balanced input with mono summing on
the back of the receiver through Phoenix/Euro block connector and three (3) via RJ45 connector on the LC372AI audio
input plate- one (1) balanced XLR mic/line switchable, one (1) unbalanced stereo 3.5mm input with mono summing, and
one (1) unbalanced stereo RCA input with mono summing. A separate RJ45 is included for connection to an intercom
handset. A balanced, line level output is provided for connection to external audio amplifiers, hearing assistance sys-
tems or recording devices.
Three infrared receivers can be connected to the amplifier to guarantee reliable connection and full coverage from the
wireless IR microphone.
