Abstract: Conference Systems are commonly used in meeting rooms or plenary halls to support the discussion of a plurality of participants. Such Conference Systems may comprise more than 50 or 100 microphone equipped delegate units, whereby each delegate unit can be assigned to a participant of the discussion. A delegate unit 1 for a Conference System is proposed, the delegate unit comprises a base body 2, a microphone stem body 3 comprising a microphone head 10 and a stem 11, whereby the microphone head 10 is arranged on the stem 11 and whereby the microphone stem body 3 is arranged on the base body 2, whereby the microphone head 10 has a directional microphone characteristic.

Abstract: The discussion unit (10) for use in a conference system is disclosed, which is adapted to be connected to at least one second discussion unit (10). The discussion unit (10) comprises an essentially closed casing (410) and at least one exchangeable portion (420). The at least one exchangeable portion (420) is removably mounted to the casing (410) and at least partially covers at least one outside part (424, 412) of the casing (410). The invention allows for an easy first installation of the exchangeable portion (420). Nevertheless, after installation, the exchangeable portion (420) is difficult to remove by a user (preventing unintended removal or removal by vandalism or “play instinct”), but allowing for an easy exchange of the exchangeable portion (420) by an installer and/or a service technician.

Abstract: A microphone has at least one non-conductive component with at least one side covered by a metal layer which in turn is covered by a protective layer, and the microphone can be a component of a delegate unit of a conference system or a congress system.
