The Brähler Automic system includes the AMic delegates microphone unit, which features a button that functions either as an on/off switch or for sending a request to speak. The unit is also equipped with a loudspeaker for decentralized sound reinforcement. One ACen central control unit can support up to 100 AMic units.

Both microphones feature a frequency response of 50Hz to 18kHz.
The PolarChoice Satellite from Electro-Voice is designed to accept Telex and Electro-Voice bodypack transmitters hidden in the base of the microphone. The on/off switch can be programmed to function as a latching on/off or push-to-mute switch. The mic features selectable polar patterns: omnidirectional, cardioid, supercardioid, and hypercardioid. Available gooseneck lengths include 5in, 12in., or 18in.
