Installation considerations for SMART Audio 400
classroom amplification system
l
SMART provides cables that should be long enough to wire a classroom. If the installation
requires longer cables, choose good quality cables.
l
Do not mount the receiver in an enclosed space (such as within a cabinet or the teacher's
desk or the space above the acoustic tiles in a ceiling).
If the receiver is installed in a confined space, the signal can be weakened when it passes
metal or walls, potentially leading to interruptions of the audio.
Installation considerations for the speakers
l
SMART recommends installing up to four 8Ω speakers.
o
Install any number of speakers as long as the total impedance is 4–8 Ohms.
o
Installing more speakers doesn’t make the sound louder but it does spread the sound
throughout the room.
l
Make sure there is at least 6' (1.8 m) between the wall speakers and interactive display or
interactive flat panel. The closer the teacher microphone is to the speakers, the more likely
audio feedback can occur.
l
Make sure the speakers are installed at least 6' (1.8 m) above the ground. The installation
height should align with height of the interactive display or interactive flat panel typically.
