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.

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 front panel of the 850iR.

2. Plug your laptop, MP3	AUDIO

Helpful Hint

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.
