4. While speaking in a normal voice, increase the CH. B VOLUME on the REDCAT level until your voice is barely audible. REMEMBER: This equipment is designed to supplement and distribute the user’s voice so they are able to speak in a conversational tone. Having the volume set too high will result in feedback and listener fatigue. 5. Warranty, Safety & Specifications 4. Troublshooting 3. Grip the barrel in the center section. Avoid covering the infrared emitters just below the microphone grille.
5. Warranty, Safety & Specifications 1. Turn off the second microphone. The iR Media Connector uses the same channel (channel B) as the optional second microphone (REDMIKE, LT-71, or REDMIKE Share). As a result, they cannot be used simultaneously. If you have a second microphone, turn it off before transmitting audio from the iRMC. NOTE: If you adjust the CH B volume on the classroom audio system, you will also be changing the volume for your second microphone.
