Introduction
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 includes 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.
