Hardware Overview

3. 

Mic Out:  This jack sends the headset microphone audio out to any device.  Most commonly, teachers will connect 

 

the Mic Out to a computer’s Audio Input or Mic In so students can record their voice into audio software such as 

 

Audacity.  Using an 3.5mm TS male to 3.5mm TS male cable, connect one end into the Mic Out jack on the Student 

 

Interface and connect the other to your computer’s audio input (see Fig. 8).  If you are using an audio interface to 

 

cable the microphone audio, you will likely need a 3.5mm TS male (to Student Interface) to 1/4” TS male (to audio 

 

interface) cable (see Fig. 9).

4. 

Network:  This all-important jack connects each Student Interface Unit to the main Teacher Unit at the teacher

 

station.  Use a CAT5 cable to make this connection.

TIP:

  Since each Student Interface Unit is hard-wired to the Teacher Unit, it is important to plan the layout of the room 

prior to installation.  It is difficult to move stations more than a few feet after installation and it could require you to 
re-cable individual stations.  I would also suggest working with your janitorial staff so they know not to move stations 
from their current location.  If you ever need to move a station, label each CAT5 cable with the name of the station and 
unplug it from the Student Interface Unit before moving.
