Creative Audigy 2 AD_EXT pin assignment

londonloonie

Hi

I went ahead and built my audigy 2 ZS to CT4660 cable and used PIN 15 on the CT4660 as the SPDIF IN.

All features of the CT4660 work fine with the audigy 2 zs card, which are midi i/o spdif in/out, and the multichannel digital din out.

For reference here is the wiring to perform (all info gathered from this site):

AUDIGY CT4660

(1) <- 5v -> (1)
(3) <- GND -> (3)
(5) <- SPDIF IN -> (15)
(9) <- SPDIF OUT 0 -> (17)
(27) <- SPDIF OUT 3 -> (9)
(29) <- SPDIF OUT 1 -> (19)
(31) <- SPDIF OUT 2 -> (22)
(37) <- MIDI OUT -> (25)
(39) <- MIDI IN -> (27)

AUDIGY AUDIGY
(25) <- IO DETECT -> (35)

Here is an image of the cable:

Many thanks to all those who helped discover the pin assignments on the audigy card, and good luck to any others who try this.

good news, thanks for the report

Samir

Very good job londonloonie! I hope this will encourage rest of people to try to achieve similar thing...

Keep up the good work!

hello

Somebody can give me th epin assignment of the rack live drive II because I want to connect it to my audigy 2.

Are there some hardware modifications do to ? (like change some resistors ...)

Vincent87

I've made an exel document with the connectins between an audigy 2 and a rack with Aud ext connector.


Can you tell me if it's right.

I put things i'm not sure in red.

Thanks

Man ! from where did you get that CT4660 ???

Samir

Ok, Vincent, i revised & PMed that Pins.xls file to you... If you're using Live!DriveII you'll need some hardware modifications! Check out THIS post in this very same thread...

good luck & keep us informed about what you've done so far...

It came with the SBLive! (CT4620) which I bought back in 98 (probably).

If you find someone with an original SBLive they may have one unused as all the original SBLives! came with a CT4660 (plus two midi adapter cables).

The first generation of SBLive!'s had the SBLive! with the extra card and the SBLive! Value without. (only know this for Europe). In the second generation there was a Platinum version, with a LiveDrive, in Europe LivedriveII (including optical in and out). I first bought the SBLive! then the Platinum version, so I have both the io-card and the LivedriveII. I had them both chained in my computer for a couple of years, even had them working on my Audigy1. Because I want to record some music I bought the A2ZS (24/96 ASIO2). Didn't like the fact that creative changed the pins from A1 to A2. Should have done more research.

I build a cable as londonloonie described and it works, will try connecting the other pins and using the LivedriveII this weekend, hope it works.

I've found another electrical diagram for coax-TTL converter :
http://www.fet.uni-hannover.de/~purnhage/dat/spdif.txt

It uses 74HCU04 insted of 74HC04

"The "U" in "74HCU04" means "Unbuffered" and is rather important
in this circuit. Using a 74HCU04, the input circuit will give a
clean logical low at the output if no input signal is present.
When using a 74HC04 instead, the input circuit will oscillate
when no input signal is present."

Maybe that's explain what do I have interuptions in sound. I'll build this one during this weekend

I connected all the wires as mentioned on this forum and connected both LiveDriveII and the io-card.

spdif out always works on the IO card but is only works on the LD when is is set to 48, at 96 it goes mute, (the io card doesn't)

the headphone out doesn't work
the line2/mic2 doesn't work.
the aux 2 can be heard on the line2/mic2 input on the asio drivers but is distorted

when changig the jumper from out2 to out0 the headphone works, but everything else stays the same.

Cosmo q:

- LiveDriveII doesn't support 96kHz without modification!
- In order to enable Aux2 & Line2/Mic2 you'll need to do some hardware modifications to your LiveDriveII, check some older posts in this thread...

good luck!

Cosmo q

Don't know about the soldering. I found a 2nd-hand Audigy2ZS Platinum on an internet site for €100 (~$132). I hope I'll get a response from the guy soon.

Someone posted everything works on his A2->Livedrive by changing the jumper so I wanted to give a detailed description of what works with my setup. I actually think he only tested his headphone-out.

This is a phenomenal thread. I am also trying to connect my Audigy Drive to my new Audigy2ZS card. What is most important to me is headphone out. Line2 in, and mic in. I don't do any SPDIF or optical at the moment. I also don't use the remote.

No one seems to have posted an authoritative Pin Mapping between AD_EXT and AUD_EXT on this thread. Please forgive me and PM me if I missed it. (I looked at the pins.xls file above, but Samir seems to imply that it needs correction?)

Here is my best guess at the mapping. There are a couple of AUD_EXT pins that I don't know what to do with--see notes.

AUD -- AD
1 ----- 1
2 ----- 2
3 ----- 3
4 ----- 13
5 ----- 4
6 ----- ???
7 ----- 7
8 ----- 8
9 ----- 27
10 ----- 23
11 ----- 24
12 ----- 6
13 ----- 25
14 ----- 14
15 ----- ????
16 ----- 16
17 ----- 9
18 ----- 18
19 ----- 29
20 ----- 20
21 ----- 22
22 ----- 31
23 ----- 35
24 ----- 33
25 ----- 37
26 ----- 26
27 ----- 39
28 ----- 28
29 ----- ???
30 ----- ???
31 ----- ??? 19??
32 ----- 32
33 ----- ??? 21??
34 ----- 30
35 ----- ???
36 ----- 38
37 ----- 17
38 ----- 38
39 ----- 15
40 ----- 38


Notes:

I had to tie several grounds together there at the end.

I am at a loss for how to map these AUD_EXT names to AD_EXT:
SPDIF IN #2
SPDIF IN #1
KEY
KEY
ADCSD02
ADCSD01 (I2S input line2/mic2????)
ADCSD00 (I2S Input Aux2???)

The last two are the most important to me

StainlessSteel

One more thing, what's the best way to go about building the cable? Should I shred and solder (like is shown by one poster), or can I change the punchdown on the connector?

Thanks!

mrcharliebrown

I have an Audigy SB0090 card and Audigy 2 SB0250 Drive. Any one know if / how I can connect the two?

Thanks a mill!

Samir

Funny that you aked, usually people wants to connect Audigy2s to Audigy1 drives... But yes, this should be possible...

mrcharliebrown

Do I follow the same pinouts contained in this forum?

Samir

Yes, follow AUD_EXT pinout for SB0090, and AD_EXT pinout for SB0250... You don't have to connect unused pins. It would be best to make your own cable... Nobody tried to connect OLDER card to NEWER drive, so your attemp might be very interesting...

good luck!

Hi

Bridgeing pins 25 and 35 ... what is this actually for.
I have Audigy 2 (SB0244) cadr. Can I benefit of it if do bridge them?

jii

Samir

Bridging 25 to 35 is nesessary for Creative driver to enable AD_EXT S/PDIF & I2S inputs & outpust. IT FAKES Creative's driver, on the way it assumes that Audigy2Drive IS PHISYICALY CONNECTED...

jiiteepee

Hi

Since i'm after 24-bit ASIO on Audigy 2 (neither Zs nor Platinum with ext. unit), I'm interested if this bridging fakes setup program to 'see' my card as a Platinum eX -model when I do the 'software mod' (install A2 Zs software) and so allows 24-bit ASIO mode.

Or, I'm I just waiting too much when trying to get my card working with 24-bit ASIO?

Hmmm, i'm not sure this is possible, due to Creative driver... You can get REAL & clean 96kHz/24bit input only if using Audigy2drive, or PlatinumDrive (Aux2 and/or LinIn2 on these expensive expansion front panels for Audigy2, i'm not sure how do they call them anymore...)

It's a kind of pysichal limitation...

Hi all,

First thanks for the information contained in this thread, it has already allowed me to use my existing coax connector with by OEM ZS card without having to make up another cable!

Now onto my question (apologies if this has already been covered but I have been through the post and haven't seen anything specific). I have recently replaced my PC with a Dell containing a SB Audigy 2 ZS OEM (SB0350) and because it didn't have optical outputs (like my previous PC) thought I'd buy a Audigy 2 Pro external box (SB0290) off ebay. However as you'll no doubt know and I've just found out, the two don't go together...

So the question is, can I use the AD_EXT and SPDIF_IO to connect to the AD_Link 1 port on the ext. box if I make up a suitable cable, and if so any ideas of the pinout mapping to that AD_Link 1 connector?

Quite happy to experiment with this box as at the moment it's totally useless - i've already had it apart with my meter on it, but I think I need a few pointers

Cheers,

Ian

Well, i've read every post in the forum, and made the cable. Problem is, it partially worked. I did hear a lot of loud hiss, and in the background i heard the audio from my DVD player coming in through the SPDIF input of my Live Drive 2 unit. But that's it. Not sure what happened. I spent 4 hours making the cable. (Only because i was taking my time with the 40 wire cable, making sure there were no errors made.)

So, since something is wrong, i don't know what to do. I am using an Audigy 2 ZS card with an Live Drive 2 unit. And the home made cable. Has anyone else with this setup actually got it working? If so, could i possibly buy one from you? I really don't feel like making yet another and finding out i'm still doing something wrong somehow.

If anything, maybe i could just wire a coaxial input/output (spdif in/out) to one of the pins on the Audigy 2 itself. I went ahead and through the Audigy 1 (using pax Newyear2005 package) back in so i'm using both cards now. So i can still use my keyboard (MIDI) using the Audigy 1 card with midi input on front of Live Drive2 unit, along with Headphones i use here and there.

Hopefully someone has a little insite on what up with this. Thanx again guys. I've been reading so much, my head is hurting. And a big headache from spending so much time wiring a new cable, and then only to find it's not working still. Eghh!! Thanx for any help.

Hi

I'm have just a Audigy 2ZS and a Audigy (not 2 just audigy) drive/frontpanel and am planning on creating a cable. Thus I have 3 questions:

1. Has anyone any refinements to StainlessSteel pinout (on page 13 in this thread) for this cable. Im wondering cause of all the ?? marks in it.

2. About the power connector. I noted that creative is supplying such, but I aint got one. I do got a matching connector coming from my ATX power supply that from left to right, seen from the audigy drive power connector pin directon p.o.v. with the aud_ext to left of it, would connect yellow, black,black, red into the audigy drive power pins. Is that correct?

3. Will I be able to use soundblasters supplied drivers as is? Will there be some noticable incompabilities (as to use a real audigy 2 drive/frontpanel)?

Would be really glad to get feedback on this.

PM me your e-mail adress i'll send you changed xls file. If someone can host & post this changed file please do...

There is only ONE SPDIF_IN at AD_EXT so you'll have to choo
