The CS 2 is the ideal solution for venues where no sound engineer is available permanently such as meeting rooms, town halls, etc. The central Base Unit controls microphone channels and a priority button allows one or more chairpersons to call the meeting to order. Two types of Microphone Units are available, the Chair Unit with a priority button (any number of Chair Units can be used in a system) and the Delegate Unit. Providing two loudspeakers, two headphone outputs, and a "Voice Zoom” function, each version can be used by two persons.
For permanent flush mounting e.g. in a tabletop an optional mounting frame CS 5 MF is available.
The CS 2 uses AKG's famous Modular Series capsules that connect to the Microphone Units via a GN 30 CS (approx. 12 in./30 cm) or GN 50 CS (approx. 20 in./50 cm) gooseneck. A rugged, threaded TRS mini jack with gold plated contacts ensures a firm, wobble-free mechanical joint and excellent electrical contact. Five different ready-to-use cables in standard lengths between 4 ft. (1.25 m) and 66 ft. (20 m) are available for connecting the individual Microphone Units together. This does not only save time but increases the reliability of the system. A range of optional accessories will solve any installation problem. With its wide variety of options, the CS 2 is more flexible than many "fully digital” systems. Plus, the AKG brand name stands for excellent sound and high reliability.
Bottom panel dip switches and pots on each Microphone Unit allow many functions to be adjusted individually.

The CS 5 DU is the basic microphone station for use in discussion systems.
Like all other CS 5 microphone stations, the CS 5 DU provides maximum acoustic flexibility. Choose from two goosenecks of different lengths and five microphones with different polar patterns to meet every requirement of any type of conference system.
In addition to the usual PTT key, this microphone station offers two advanced features previously found on more expensive conferencing equipment only: A bank of dip switches allows each headphone output to be assigned independently to either the floor channel or one of three interpreted language channels. The PTT key also provides a simple yes/no voting function.
Gooseneck, capsule and connecting cable are not included.
It shall have a built-in microphone and loudspeaker, which allow the forwarding of the voice of the speaker towards the other units of the system. The CS 5 DU shall be capable for 1 step voting from the unit with the help of the speech button.
The CS 5 DU is suitable for taking over maximum 3 interpreted languages and the room voice as well, which may be selected via a set of DIP switches on the bottom of the unit. The unit shall operate for 2 persons simultaneously, with independent adjustable languages for each of the 2 x 3,5mm stereo jack headphone sockets.
