Glensound GDC 6432 dCU/3 Digital Commentators' Unit
Description
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.
There are 8 inputs and 8 outputs on the dCU/3. Not all of these are pre-assigned and are available as auxiliary IO. On the rear panel there are analogue and AES inputs and outputs.
The dCU/3 is powered via the link to the dCCU using coax or copper Ethernet. If the fibre link is used the dCU/3 is powered via an external DC supply.
Digital Link
The link between the dCU/3 and the dCCU carries 8 channels of bi-directional audio at 24bit 48 kHz. There are 3 options on the type of link; 1) Coax, giving a 400m range and carrying audio and the power for the dCU3, 2) Copper Ethernet, giving a 100m range and carrying audio and power for the dCU3, or 3) Fibre Ethernet, giving kilometres of range with the dCU3 being powered locally.
Ethernet Remote Control
You can remote control and monitor, levels and audio via any Ethernet connected PC. The remote control facility operates within a PC browser as a Java application and connects to the GDC 6432s internal web browser via IP. The visual mixer representation shows real time settings of the dCU3 and the dCCU, allowing engineers to see the commentators pot positions, monitor and adjust mic gain levels, turn on or off mic phantom power, monitor any input into the dCU3, and adjust the output mix level, for example. Whats more an engineer is an active participant in the system, as the remote link also carries uncompressed audio (2mb sec), allowing the engineer to talkback on any of the 4 circuits, talkback to any commentator, or record the line idents, for example. This is suitable for remote control inside an OB truck, or via a high capacity WAN back to an International Broadcast Centre (IBC). Using an ISDN or IP codec, this remote audio link could easily be transmitted worldwide.
