Conference System
DCN-FCS Headphones level reduction
When you use a Concentus delegate unit with a DCN-FCS Channel Selector, you must connect
pin 1 and 5 of the RJ45 socket to the level reduction plug of the channel selector. This
prevents acoustic feedback.
Figure 6.21: Channel selector, connection
When the microphone that is connected to the Concentus delegate unit is enabled, the
channel selector automatically decreases the volume level of the signal that is sent to the
headphones of the channel selector.
