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.
If your system includes two REDMIKEs, we recommend using Channel B (student 
mike) to amplify the external audio equipment so the teacher’s volume on the 
Channel A (teacher mike) does not have to be adjusted. 
To determine which REDMIKE is set to Channel B, you can look at the switch on 
the back of the mike or speak into one of the mics and watch which set of LED’s 
glow on the front panel of the REDCAT (A Volume or B Volume correspond to 
Channels A or B).
1.  Plug your external audio 
equipment (for example, laptop), 
into the input on the REDMIKE 
labeled “INPUT” using a 3.5mm 
patch cable.
