The
SMART Audio 240 system amplifies the teacher’s voice so that students who sit in the
back of your classroom hear you as clearly
as those who sit in the front. The audio system
makes speaking to the class more
comfortable because you don’t need to strain your voice to
get your students’ attention.
Your SMART Audio 240 system includes the following items:
•
one receiver
•
one power supply
•
one teacher microphone with
lanyard (lanyard not shown)
•
one handheld student microphone
•
two microphone chargers
•
four rechargeable batteries (not shown)
•
one ceiling infrared sensor
•
four wall or ceiling speakers
Receiver
Your SMART Audio receiver has two
microphone channels so that you can use the
teacher microphone and the handheld student
microphone at the same time. It has two audio
line inputs that allow you to connect an external
audio device like a CD player, DVD player,
computer, TV or VCR. You can record audio on
your computer or other devices.
Each microphone channel and external audio device line has a
volume control so that you can blend softer and louder speaking
voices with audio from external
devices. You can change the
audio tonal quality by adjusting the tone dial on the receiver.
There’s an infrared sensor on the front of the receiver that detects
the microphones’ infrared signal. You can use either the infrared
sensor on the receiver or up
to three external ceiling sensors.
Microphones
Your SMART Audio system inclu
des a teacher microphone and
a handheld student microphone. You can attach the included
lanyard to the teacher microphone and wear it around your
neck. You can use the handheld student microphone when
team teaching, or you can pass it to students and allow them to
participate in lesson activities.
These microphones have power and channel selector switches.
The battery indicator light glows green when the batteries are
fresh and glows red when the batteries need to be recharged or
replaced.
There are transmitters on the microphones that transmit an infrared signal. To ensure optimal
performance, don’t cover or block the infrared
transmitters. There must be a clear line of sight
between the microphones and the infrared sensor in order for the audio system to work
properly.
Microphone Chargers
If you use the included rechargeable batteries, you can
recharge the microphones by connecting a microphone charger
when the battery indicator light changes from green to red.
Fully charged batteries last approximately eight hours in the
teacher microphone. For the handheld student microphone,
fully charged batteries last ap
proximately six hours when you
set it to
High
and approximately nine and a half hours when you
set it to
Low
. It takes approximately eight hours to fully recharge
the batteries.
Infrared Sensors
Infrared sensors detect microphone signals and send them to
the receiver. You can use either the infrared sensor on the
front of the receiver
or the infrared sensor for the ceiling.
Ensure that there is a clear line of sight between the infrared
sensor and the infrared transmitter on the microphones.
Speakers
Your SMART Audio system co
mes with four wall or ceiling
speakers. The speake
rs mute if the signal from the
microphones is blocked or weak. This prevents unwanted
static and noise from occurring.
