Building your own DB-25 to audio cable
Hello everyone,
considering buying a soundcard (Delta 1010) without the breakout cable. As far as I know, this DB-25 pin connector on the back of the Delta is standard M-Audio, and wiring my own up to RCA or even my own choice of unbalanced connector shouldn't be difficult at all. Anyone have any links to help? I can't find any for the life of me. Help! |

It may be the same as used by Digidesign for their 192.. if so download the
manual for the 192 from their web site.. it has a wiring diagram. Rail -- Recording Engineer/Software Developer Rail Jon Rogut Software http://www.railjonrogut.com "Al" wrote in message m...

m considering buying a soundcard (Delta 1010) without the breakout cable. ....but hopefully with the interface box. The 1010 card is pretty useless without the interface box because the converters are in the interface box. OTOH, if you are talking 1010LT, then that cable is passive. But the 101LT cable connector has a lot more than 25 pins - more like 44 (rough count). As far as I know, this DB-25 pin connector on the back of the Delta is standard M-Audio, I wasn't aware that M-Audio had a standard for this kind of cable. If they do, its probably straight-through. But, I don't know what the pairing is, off-hand. Even straight-though cables aren't necessarily generic or standard. and wiring my own up to RCA or even my own choice of unbalanced connector shouldn't be difficult at all. AFAIK, the connection between a Delta 1010 interface box and the sound card is 100% digital. I don't know how balanced or unbalanced would relate to that. Anyone have any links to help? I can't find any for the life of me. I have a 1010 if that is any help, but its at a remote site. |

Last time I checked it wasn't a DB25 connector. However the proper connector is available if you look hard enough, and I can't see any reason not to make your own rather than use extension leads with the original. TonyP. |

I think M-Audio says a max of around 12 feet, I've got about a 15 footer with no problems, but I relocated the rack the breakout box was in and to get the cable out of the way I'd really need to run about 20 feet.

Sorry, no. I suspect that the cable is transmitting an internal interface that is TTL-based, so capacitance is probably more of an issue than resistance. Both can be managed if you can select the cable wiring carefully. Of course, few who have ever done so, actually want to go out of their way to solder up the cable for themselves. 25 and even 50 foot cables have worked for PC printers which also have a TTL interface, but that is probably a far slower signal. I think M-Audio says a max of around 12 feet, I've got about a 15 footer with no problems, but I relocated the rack the breakout box was in and to get the cable out of the way I'd really need to run about 20 feet. Were it up to me, I'd just run a longer analog snake from the interface box to the console or wherever the mic preamps are. I see no special joy in having the interface box near the source. It's basically a set-and-forget thingie, anyhow. BTW I just picked up a 1010LT to expand from 12 to 16 channels by replacing my Delta 66. The Delta 66's unbalanced inputs seem to be working well, so why not? In this case there's nothing but analog to extend, and my plan is to cut 4 12' RS "Gold" RCAs in half, and solder on TRS plugs wired to bridge the inserts on the host SR-32. If you haven't noticed, M-Audio has a pretty good discount sale going on most of the Delta series, including both flavors of the 1010. |

om Sorry all for not being more precise. I'm looking at buying a 1010LT (the one with RCA connectors) but it doesn't come with the connector cable. http://m-audio.com/images/en/callout...ta_1010_lt.jpg Looks like some custom stuff for the analog connector about 46 pins. I suspect its some kind of standard DB connector. I count two rows of 15 pins and one row of 14 pins, but I'm a lousy counter. The digital is a DB-15, though I don't really care about the wordclock I/O just MIDI. Hope you're getting one whale of a cheap price, because current retail for a 1010T is about $215 Any ideas on how to build this? 2 appropriate DB connectors, an audio generator or other stable analog signal source (e.g. a CD player playing a CD-R with test tones) and a scope or at least a meter. I am looking for a pin-out diagram or some method to find out using basic audio tools. Signal negative lines should be easy since almost nothing is balanced on the 1010LT. They are all ground but the two balanced inputs. Outputs can be done with a scope and any program that sends a known signal out the outputs. The "Audio Rightmark" test program seems to be a reasonable piece of highly flexible freeware for activating outputs. Analog inputs can be done with an appropriate analog signal source and an appropriate program that records. You can even use one of the analog outputs as a signal source. The only lines that even take much thought is the MIDI and the digital input. You're going to need a separate SP/DIF signal to confirm the digital input. It would probabaly be best to use real world MIDI hardware to confirm the MIDI I/O. OTOH, MIDI outputs are pretty distinctive on a 'scope. In a pinch, you could even meter it. I'm really determined to do this as I would build a little patchbay as an external plate for the soundcard instead of re-creating 16 RCA connectors. Or, a break out box. You could populate it with TRS jacks and impedance-matched outputs and then you would have a Delta 88. ;-) |

I don't think I'd want to build my own - fat fingers and feeble eyes don't work well with sub-subminiature contacts. True, but I don't particularly like the idea of all those short leads with RCA sockets, followed by more leads with RCA to phone plugs that I require. Then again it may be quite a problem getting 16 cables or a multicore into a D25 shell too. TonyP. |
