An important note: Digidesign uses a DB25-to-XLR harness for AES/EBU I/O on their new ProTools
HD system, but the pinout is different. They put four AES/EBU sources and four AES/EBU
destinations on a single DB25-to-XLR cable. We put either eight AES/EBU sources or eight AES/EBU
destinations on a single DB25-to-XLR cable. We can supply you with ProTools HD-to-Digital
Detangler Pro adapter harnesses.
Also note that the naming convention in Figure 2 is based on stereo pairs. For example, pins 1G, 1+,
and 1- would connect to the three pins of an XLR connector for AES/EBU, and this connector carries
two channels of digital audio. Thus, a single DB25 connector carries eight stereo pairs of digital
audio.
Furthermore, the naming of the various models references how many stereo pairs of digital audio
are supported. For example, the z-32.32r has 32 stereo pairs in and 32 stereo pairs out. The units
can not cross-route different halves of a stereo pair; all routing must be done on a stereo-pair basis.
You will want female XLRs on the source harnesses and male XLRs on the destination
harnesses. If in doubt, or if you wish to make your own cable assemblies, Figure 2 shows the
proper pin-out for both the source and destination connectors.

The configuration of the Digital Detangler Pro is defined by a set of "to/from" pairs. Each
"to" can have only one "from" sent to it at a time (to do otherwise would require a digital mixer).
