Cat cable

For using CAT wiring intended for Ethernet to carry Balanced Analog instead

this really is a completely different discussion from AoIP protocols, much less generic Ethernet networking

the use of standard Cat6A ScTP (Shielded Twisted Pair) cable allows for one pair to carry each analog audio channel, the shielding being in common, thus 4x balanced audio channels per RJ45 connector.

This is standardized as AES-72 (type 1, "audio-over-CAT") wiring.

What I'm after is a reasonably priced pre-wired adapter module pigtail and/or Neutrik D-size cutouts in a grounded rack patch panel

that converts a pair of RJ45 to DB-25 TASCAM pinout (AES59) wiring for 8x balanced analog.

I believe the same scheme can carry AES/EBU digital

Can anyone suggest Reasonably Priced mfg brands and / or supply sources?

@Kal Rubinson
I use Thomann ssSnake and StudioHub devices but I have not used any that are DB25 <-> RJ45 because I need the breakouts.
 
ASR has a rep out there for being BRUTAL. That is not something to be proud of...
If that rep is for being BRUTAL to people trying to push subjective audiophile nonsense, then it very much is something to be proud of.
 
When we (me/wife/dog) had our new home built in 2008, I had 48 runs of cat 5E laid...so I have a structured wiring layout where all runs terminate in a patch panel in my office.

This was needed as I was a home based enterprise software developer with twenty unix/linux servers that I used for dev/test and compilations (aix, hpux, solaris, redhat, ubuntu, suse etc). I was a global tech lead (retired in 2020) for a computer company with 400,000+ employees worldwide to frame what "enterprise software" means. Also note that the software developed was predicated on the use of tcp/ip sockets so I have some understanding of tcp/ip, ethernet and networking.

Testing involved destructive use of database images (oracle, db2, sybase, informix, teradata, postgres, mysql etc) and so I would need to copy between servers > 100gb to refresh a database image.

With servers in different zones in the house (dev/test/prod/backup), this meant the copies occurred over long runs of cat 5e (say 30m inbound, 30m outbound via my patch panel and through an enterprise switch) and I would get (still do) 110-112 MBYTES of data per second (i.e. the max a 1000mbit ethernet card can support).

Note the above description is not a "look at me" thing but to note that my use of ethernet in my home was critical/fundamental to my job (and my customers) and not for a non-critical thing like home audio.

I raise this (long) description because stupid/gullible people believe CAT6/CAT7/CAT8, for example, provide some advantage in a home situation. No home audio gear needs 10gbit/sec throughput... plain old 1gbit cat 5E has 50 to 100 times the throughput needed (as per my real world example above) for an audio stream.

These stupid/gullible people might also believe that CAT7/CAT8 cables have some magic sauce that reduces noise and while this can be true in an ENTERPISE situation (depends on the CAT topology/terminations used), plugging in a CAT8 cable into a 1gbit ethernet port (I.e. what consumer level gear has in it) won't magically impart reduced noise... this is without discussing the fact that even lower spec ethernet cabling/transceivers are designed/implemented with robust noise reduction.

And lets not get into why stupid/gullible people believe that a fancy $$$$$ reclocking network switch is needed for a non-serial, async transfer protocol based on a store and forward topology (and where every network device in the chain reclocks the packets anyway)

If you are paranoid, spend less than $100 on a pair of TPLINK MC200 media convertors (and an optical fibre cable) placed in front of your DAC/streamer and be done.

Nurse...Nurse,,, where are my pills!!!

PS. In the decades prior to this home build, me and the servers lived "happily" together in a large room in the old house so I was very happy they were given special rooms away from me!!!

And as the years went on, servers supporting say DG/UX and Sequent Dynix/PTX would be retired as well as newer hardware introduced to support current versions of Unix.
