USING THE REDMIKE TO AMPLIFY EXTERNAL AUDIO EQUIPMENT
The REDMIKE includes a 3.5mm audio input jack to connect to an audio source like 
a laptop or MP3 player. The REDMIKE will transmit the audio signal to be played 
through the system.
LT-71
The optional LT-71 can also amplify external 
audio. Simply plug the 3.5mm patch cable 
from the audio source into the input labeled 
“AUX IN” and adjust the volume of the 
source to the desired sound level.
Helpful Hint
1. If your system includes two REDMIKEs, use 
the student microphone (already set to 
Channel B). NOTE: This feature works on 
both channels but we recommend using 
Channel B so the teacher’s volume on 
the CH A does not have to be adjusted. 
REMEMBER: It’s easy to determine which 
REDMIKE is set to Channel B by speaking 
into the mic and watching which set of LED’s 
glow on the side of the REDCAT.
2. Plug your laptop, 
MP3 player or other 
audio source into 
the input on the 
REDMIKE labeled 
“INPUT” using a 
3.5mm patch cable.
