1 AES/EBU DIGITAL OUTPUT
This output provides the digital audio signal (DAS) via cables equipped
with XLR-type connectors to the digital audio processor.
This input conforms to the Audio Engineering Society/European Broadcast
Union (AES/EBU) professional digital audio standard, which calls for a 110Ω
transmission of the DAS. Use a digital interconnecting cable specifically de-
signed for the 110Ω AES/EBU standard, such as Madrigal MDC-1 cable,
when using this input, with pin assignments as indicated below:

Pin 1: Chassis ground
Pin 2: non-inverted digital
Pin 3: inverted digital
Connector ground lug: chassis ground
It has been Madrigal’s experience that the AES/EBU interconnection stan-
dard offers the best quality of all digital transmission interfaces when fully
optimized, and we recommend its use wherever possible between Proceed
components.
However, optimizing any digital interface completely represents a significant
engineering challenge. It is entirely possible that a different type of input
may actually outperform a less-than-optimized AES/EBU implementation on
some brands of digital processors. For this reason, we have gone to great
lengths to fully optimize all four of the digital outputs on the CDD. If you
are using you CDD with a different brand of processor, we recommend ex-
perimenting to determine which type of input on that processor results in
the best audible performance.
