The unit also controls the chairman and delegate unit microphones, as well as providing connections for audio inputs and outputs.\u003cbr\u003e \u003cbr\u003e CCS‑CU Control Unit\u003cbr\u003e \u003c\/p\u003e\u003cul\u003e \u003cli\u003eDigital Acoustic Feedback Suppression\u003c\/li\u003e \u003cli\u003e\u003cfont face=\"Arial\" size=\"2\"\u003eDiscussion control without operator\u003c\/font\u003e\u003c\/li\u003e \u003cli\u003eControls up to 150 contribution devices\u003c\/li\u003e \u003cli\u003eBuilt-in monitor loudspeaker\u003c\/li\u003e \u003c\/ul\u003e \u003cstrong\u003eDigital acoustic feedback suppression\u003c\/strong\u003e\u003cbr\u003e \u003cbr\u003e The digital acoustic feedback suppression facility automatically eliminates acoustic feedback (also known as ‘howling’ or ‘Larsen effect’). This gives better speech intelligibility by allowing the speaker volume to be turned up as loud as required without any risk of feedback. \u003cstrong\u003eDiscussion control without operator\u003c\/strong\u003e The CU can be setup to operate standalone without the need for an operator. The following 5 modes can be chosen using a rotary control on the unit’s top panel:  \u003cul\u003e \u003cli\u003eOpen mode – allows selection of one to four microphones (excluded chairmen microphones) which can be simultaneously active\u003c\/li\u003e \u003cli\u003eOpen mode with auto-switch-off – allows selection of one to four microphones (excluded chairmen microphones) which can be simultaneously active.
