The GDC 6432 is a 2 part digital commentary system, consisting of a 3 commentator/producer unit (dCU3) and a 1u 19inch base unit(dCCU).
dCU/3 digital Commentators' Unit
The dCU/3 has complete facilities for 3 separate commentators. Each commentator can connect dynamic, ribbon, or condenser microphones (48v switchable), and connect a pair of headphones via 6.35mm sockets.
Each commentator has 8 independently adjustable level feeds to create their own preference of headphone mix. These inputs typically include, programme, feedback, international sound, co-ordinator, and technician - for example, although they can of course be anything. Each input can be placed at the preference of the commentator, to either or both ears. There are also 4 talkback circuits selectable per commentator.
There is an additional line level input on the front panel that has its own on/off and is switchable onto the talkback circuits.
Operation of all dCU/3 switches is configurable using the Switches software.
