Quote from: alancarl on August 05, 2023, 06:34:36 AMI'm getting ready to Connect my 13 pin Godin to the GKC-AD to the GM 800 and of course nobody seems to have this TRS digital audio-data cable from Roland in stock.So I'm thinking I will roll my own. Ive got the wire requirements-basically like AES/EBU cable.My question is the Roland cable has fancy 24 karat gold TRS connectors. I looked inside the GKC-AD and those pins do not look like gold to me.I have been in the practice of not mixing gold and nickel plated as this will cause oxidation and a dielectric between the two dissimilar metals.Does anybody know if the jacks for the Roland GK serial interface actually have gold plated pins?(i don't feel like opening up one of the boxes to investigate as that might void my warranty or negate my unlikely return of the merchandise)ThanksAl

Quote from: Wonks on August 05, 2023, 07:37:24 AMI really wouldn't worry about it. You need an ionic liquid, e.g. I expect you'll be plugging in your cables just as much as you'd plug in a guitar cable, and the mechanical action will help remove any slight oxidation on the non-gold contacts.

Quote from: jackeb77 on August 15, 2023, 02:58:24 PMHi. I'm new to all this.I'm looking to get a cable made.Should I be using 1 pair or 2 pair cable.In the UK I'm looking at this cable. Has foil shielding. Is it suitable?https://www.van-damme.com/vandamme_product/van-damme-super-green-series-digi-grade-enhanced-aesebu-110-ohm-pre-jacketed-cable/#1537534704632-c472e6a0-7e3824df-956f152f-d9c11 pair 268-431-050: Conductors 7 x 0.25 mm bare ultra-pure oxygen-free copperConductor size 7 x 0.25 mm, 0.34 mm2, AWG 22/7Insulation Foam Skin PolyethyleneScreen type 24 µm Aluminium/Polyester Foil >150% coverageDrain wire 19 x 0.12 mm bare ultra-pure oxygen-free copperOverall jacket Flexible PVC composite Leaf Green RAL 6002Overall diameter 4.80 ± 0.15 mmBend Radius 10 x overall diameter
Quote from: Elantric on August 15, 2023, 03:10:29 PMOne TWISTED pair cable , with foil shield drain wire , wired 1:1 at both TRS ends TIP = WHITE = TIPRING = BLACK = RINGSLEEVE = SHEILD DRAIN =SLEEVE I just order this twisted pair + foil shield AES/EBU cable and cut off the XLR plugs and solder my own TRS plugs
Quote from: jackeb77 on August 15, 2023, 03:14:45 PMThanks.Is the van damme cable I quoted above twisted pair ? Thanks for your helpEdit It says.. Van Damme Super Green enhanced AES/EBU cable is a foil screen overall braid multicore and a PVC jacketed one pair cable
Quote from: Elantric on August 15, 2023, 03:20:36 PMShould work fineJust avoid common microphone cable or TRS audio patch cables that do not have the important foil shield - else you may experience high frequency noise invading adjacent 13pin cables The SERIAL GK cable could be prone to become a high frequency noise source if use TRS cables without that important foil shield
Quote from: jackeb77 on August 15, 2023, 04:11:23 PMOK that's great to know.The mogami 3080 cable I've seen mentioned on here.. I can't find anything about it having a foil shield. It has twisted pair and sheilded but can't find anything on net that tells me if it foil sheild.https://mogamicable.com/category/bulk/dig_interface/aes_ebu/
Quote from: Elantric on August 15, 2023, 05:48:04 PMIf the twisted pair AES/EBU cable under consideration does not mention Foil Shield and Drain Wire - avoid that type Twisted pair and braided Shield alone ( no foil shield) is not suitable for SERIAL GK Id not recommend Mogami 3080 cable - no foil shield https://www.markertek.com/product/mg-3080/mogami-w3080-2-cond-110ohm-aes-ebu-digital-audio-cable-black-per-foot
