The CS3 BU is the base unit for the CS3 conference system and provides all the necessary inputs and outputs to manage a conference for up to 60 microphone stations. It is the interface to all audio devices in a meeting room and offers a RS232 interface to connect an optional camera control system. On the Base Unit you can select one of four conference modes:
The NOM button sets the number of mics allowed to be active simultaneously (1,2,4,6 delegates). The final 3 buttons control the bass, treble and master volume.
The CS3 CU (Chairman Unit) is a microphone station with two operating modes. In priority call mode, the user can manually mute all connected delegate stations. In next in line mode the CS3 CU automatically activates the next delegate station in the waiting list.
The CS3 DU (Delegate Unit) microphone station is the basic delegate unit for the CS3 conference systems. Depending on the selected operating mode, the Push To Talk key enables the speaker to directly switch on their microphone or to enter the system waiting list.
Both stations provide a built-in speaker and 2 x 3.5 mm stereo jacks to connect headphones for up to two delegates. The detachable microphone comes in two choices - the CS321 cardioid condenser capsule on a 30 cm long gooseneck and the 50 cm long CS521.
