2.2 HARDWARE CONNECTIVITY
All connections to the DDRC-88A are made on the rear panel.
2.2.1 Analog input and output
Up to eight channels can be connected to the DDRC-88A. Be sure to take careful note of the channel numbering:
On the input side, it is very strongly recommended that all connections be of the same type – i.e. balanced or
unbalanced. The Dirac Live algorithm equalizes levels on all channels, and a mixture of balanced and unbalanced
connections on the input side will require special gain adjustment steps after Dirac Live calibration.
On the output side, a mixture of balanced and unbalanced connections can be used if desired. Doing so may
necessitate additional work to check and adjust system gain structure. For more information on gain structure,
see Gain structure starting on page 38.
Unbalanced connections are made directly
to the RCA jacks.
Balanced connections are made by
connecting bare wire ends to the push-in
Phoenix terminal blocks. For advice on
using these, see Balanced wiring tips on
page 48.
