CS 1
Conference System
Description
The AKG Model CS 1 is an extremely flexible and sophisticated
A single CS BU 1 base unit will handle 100 user microphone units in four
1.Input level controls: active microphones, line, and auxiliary. The line input can accommodate additional signal inputs, such as wireless microphones; the auxiliary input accommodates an external stereo audio source.
2.NOM (number of microphones) setting; determines the maximum number of microphones that may be open at one time; useful in maintaining orderly discussions. Up to five simultaneous microphones inputs may be on at a given time.
3.Loudspeaker level control. Sets level of output signal which is fed back to the nearfield loudspeakers located in each individual user station.
4.Line output control. Sets level sent to local sound reinforcement facilities.
5.Recording output. Determines the level of the stereo output signal intended for recording program proceedings.
The CS DU “delegate” user station provides management via
1.Microphone sensitivity adjustment (high or low)
2.Automatic muting after long pauses (on or off)
3.Muting time setting (long or short)
4.NOM, on or off (allows distinguished participants to speak, even when NOM limit has been reached)
5.Voice/pushbutton activation (allows distinguished participants to speak without using pushbutton); when a user station is activated, its internal loudspeaker is muted in order to avoid feedback.
The CS CU “chairman” user station is designated for chairman and
On all user stations a bright red LED ring just below the microphone capsule lights up when that microphone is actuated.
Figure 1 shows a typical setup using a single base unit, and Figure 2 shows as typical setup using a single base unit plus an expansion unit.
