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

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.

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.
