Power Inlet
The Coda Audio DNC260 unit should be connected to a suitable mains electricity supply
using the cable supplied. The processor has a switch mode power supply that is capable of
operating with a nominal mains voltage of 85V to 240V, 50/60Hz without re-configuration.
Network Expansion Port
When fitted with a network option, the network connections will be here.
Audio Input Connectors
All audio connections are fully balanced and wired pin-1 ground, pin-2 hot & pin-3 cold. The
two inputs have pin-1 connected directly to the chassis and feed the signal processing
chains. If an unbalanced source is used, a connection should be made between the pin-3
‘cold’ signal and the ground connection of the unbalanced source.
Audio Output Connectors
The processed outputs are impedance balanced, and wired pin-1 ground, pin-2 hot and pin-
3 cold. An unbalanced input may be driven by connecting pin-3 ‘cold’ signal to the ground
connection of the unbalanced destination input. Note that output pin-
1’s are ground lifted
at audio frequencies but connected to ground at RF for good EMC performance. The
intention being that the amplifiers the processor is driving should be responsible for the
grounding of their input cable shields.
