Default 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.

....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.

Arny,

Do you have any experience with running longer cables from the PCI
card to the breakout box?

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.

card to the breakout box?


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.

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.

Why? Why don't you look for one that has the cable? Every one that
M-Audio sells comes with the cable. Where's the cable for the one you
want to buy? Still at the studio the computer was stolen from perhaps?
I'd be careful about buying an incomplete product that's still in
production and selling new.

Any ideas on how to build this? I am looking for a pin-out diagram or
some method to find out using basic audio tools.


If you really want to know, contact M-Audio. Ask them how much it
costs to buy one, and if the cost of the cable plus whatever you can
buy the card for is more than a new 1010LT (or more than you want to
pay for one) then pass it up and wait for a better deal.

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.


That's actually not a bad idea. If you had the origial cable, you
could trace it out and make a patchbay equivalent. But if you have
found one to buy without the cable, I'd be careful for reasons other
than that you don't know how to connect it to the real world.
