This ANNY® Receiver Module allows retrofitting of an ANNY® wireless microphone by installing it in a free receiver module slot of the ANNY® loudspeaker. It receives with the frequency band B6 the frequency range of 655 - 679 MHz. A volume control on the module allows you to set the volume level to suit your needs, while a mute level control effectively eliminates noise and interference caused by weak signals. Radio signals can be received up to 80 meters using the supplied antenna with a TNC connector. The receiver is easily and conveniently synchronized via infrared with the matching ANNY® bodypack transmitter or wireless handheld microphone.
