4-wire talkback can be installed on all units in the Direkt series and provides bidirectional mono channels for control room and studio sound. An example of use is when a photographer communicates with the master control room on one channel, while the reporter talks to the studio/gets program feed on the other channel. Another usecase is when several locations are connected with each other and/or the control room.
Multiple devices can be included in the same group and the user easily chooses who should be able to talk to each other through ISS. All communication takes place with low latency and high audio quality.
