( MADE IN JAPAN ) The BMB IR-A Dual Wireless Microphone is the 2MHz version (3MHz IR-B Model also available) of BMB's professional system. Dual IR sensors are used to create a full coverage area to use the microphones within. One IR sensor is preinstalled on the microphone receiver but can be relocated if needed. You'll then need to select the best spot for the second IR sensor depending on your environment. This provides better coverage than other wireless systems where you need a clear line of site from the microphone to the receiver. With this system, you may have an IR sensor capturing your voice in front and behind the microphone so obstructions have less of chance of interrupting your performance. You can keep microphones charged up and ready for use simply by placing them in the charging base.  Rechargeable batteries are included.
