Creative Audigy 2 AD_EXT pin assignment

**dj_stick** · Jul 26, 2004, 03:38 PM

yes this is what it does…
im sure you can buy them from somewhere - but they would be bulky, not designed for internal use in a computer case, and expensive - i would build one if i were you - www.electricstart.de has some electronics for building an analogue to digital converter, for extra inputs

Trace three wires from 3.5mm jack to J1 connector pins...
You can see pin 1 on J1 connector, it's marked with small arrow, look at right side...

I'm sure someone could make a simple DAC converter for the Audigy2 and sell them, I'd buy one but then I'm not very good at soldering. LOL

Here is a picture of the rear of the I/O Board. I believe you will find the pins you are looking for and the route they take. I am not sure how to decipher which pins belong to what on the Audio Port. The J1 connector on the Audigy 2 connect to the row of pins circled in red.

To Josh_Hayes:

This picture alone, is not much help. What i need is another picture, another side of this add-on card, including connector & cable (where i can see wich wire colors are connected to add-on module & Audigy2 card too)...

Shamelessy ripped from elsewhere, ymmv, supposedly J1 pinouts are :-

1 - Analog Ground
2 - Analog Headphone Out Left
3 - Audio Backpanel Mute -- short to ground to mute the backpanel (when headphones are plugged in)
4 - Analog Headphone Out Right
5 - same as #3
6 - Mic input from front panel
7 - key pin (shouldn't be there)
8 - VREF out -- voltage reference for Mic
9 - MIC IN MUTE -- ground when mic isn't plugged in, +12VDC when mic is plugged in
10 - Audio cable detect -- will be ground when headphones are plugged in (not normally used)

headphones & mic connections :-

FROM WHEREEEE???

**dj_stick** · Aug 2, 2004, 04:05 AM

Samir: Pin 36 on the AD_EXT - could that be a S/PDIF input? or have the dodged it away and left only 2 S/PDIF ins on the A2 cards?

Why you think pin 36 might be SPDIF input? When i traced it, it lead to J1 connector

, pin 10, which is, according to cybadog, 'Audio cable detect'. It's for headphones detection, i think... I really have no clue about where third SPDIF input might be...

Hi!

Very much thanks for the Audigy 2 Pinout. I waited a long time for this and I'm very happy find it here. Now I have good news for you. I have connected the Audigy 2 card to the Audigy 1 drive - and it works fine. IR-option, headphone, coaxial & optical SPDIF I/Os and MIDI I/Os works fine, only the microphone2/line-in2 , aux2 doesn't work. I think the problem are the pins ADCSDO2(p31), ADCSDO1(p33) and ADSCDO0(p35) (I2S audio data output) on the Drive. I tried to connect to the Audigy2 Pins I2S input Aux2(p19) and I2S input Line-in2/Mic2(p21) but the Signals are very noisy. Why do I have 3 Outputs (on the Audigy1 Drive) for A/D-Input and only 2 A/D-Inputs on the Audigy2. How can I connect these three Pins to the two on the Audigy2.

Another question. Why must I connect the p34 (Audigy2) to TAD, and why I must connect p36 to p10@J1? Which signals are on these pins?

On the drive i have 2 Outputs for SPDIF In, but only 1 Input on the Audigy 2. How can I solve this? Now i connected both of these outputs on the 1 on the Audigy2.

Thanks Offshore

Excuse me for my bad english language

**dj_stick** · Aug 3, 2004, 02:55 PM

try using CD_SPDIF for the second s/pdif signal

as for the I2S signals, make sure you connect the clock signal pins to the audigy drive

Offshore · Aug 3, 2004, 03:05 PM

I've connected the clock pins to the drive. I have a mic-signal but there is also noise on it.

That would be a solution, but why is there only one digital in on the Audigy 2?

**dj_stick** · Aug 3, 2004, 03:10 PM

i don't know the answer to the second question, you have to ask creative,

perhaps the noise is because the p16v (24/96) chip is upsampling the signal from the ADC's on the drive, which are 16/48, whereas the audigy 2 drive ADCs are 24/96

Offshore · Aug 3, 2004, 03:21 PM

Is there a possibility to change these ADC's on the Drive?

**dj_stick** · Aug 3, 2004, 04:29 PM

i don't think so

1: I'm very glad it worked! The reason why Audigy2 has only 2 I2S inputs is that third I2S input is used for onboard LineIn input, PHILIPS ADC... You can use this for 24/96 recording, just search this forum for the info how to bypass AC97 codec and get separate input trough AC97 2 - wich is onboard PHILIPS ADC... Reason because you get noise on Aux2 LineIn2 is, most probbably, 48Khz ADCs found on Audigy1 drive... Audigy2 expects 96Khz signals...

2: You don't have to connect these pins at all! Recently i've found out that p36 has 'headphones detect' function...

3: Unfortunately, AD_EXT/SPDIF_IO found on Audigy2 cards has only one SPDIF input! This IS strange, but you can always use CD_SPDIF input...

I have another question for you: Have you used setup like this???

Code:

              purpose:    Audigy2 pins:    AudigyDrive pins:
                  +5V:         1 ------------- 1 or 2, no difference...
                  GND:         3 ------------- 3
                  GND:         7 ------------- 7
                  GND:         8 ------------- 8
                  GND:        14 ------------- 14
                  GND:        16 ------------- 16
                  GND:        18 ------------- 18
                  GND:        20 ------------- 20
                  GND:        28 ------------- 28
                  GND:        32 ------------- 32
                  GND:        38 ------------- 38

             MIDI out:        37 ------------> 25
              MIDI in:        39 <------------ 27
           SPDIF0 out:         9 ------------> 17
           SPDIF1 out:        29 ------------> 19
           SPDIF2 out:        31 ------------> 22
           SPDIF3 out:        27 ------------> 9
             SPDIF in:         5 <------------ 15 (if doesn't work try 6 instead of 15)
 AC97CLK/P16V 24.5MHz:        13 ------------> 4
          I2S1 (Aux2):        19 <------------ 33
 I2S2(ALine-in2/Mic2):        21 <------------ 31
                 GPI0:        35 <------------ 23 
                 GPI1:        33 <------------ 24   
                 GPO0:        25 ------------> 13    
                 GPO1:        23 ------------> 10   
                 GPO2:        24 ------------> 11

Please make a similar drawing of cable you made to connect every pin, and post it here for other users...

Thank you!

spdif_io on audigy 2 zs (SB0350)

spdif_io and ad_ext looks same as on the picture, unfortunatelly if i connect coax out from external dvd to pins 5-6 nothing happen. if i connect it to cd digital in it works.
is there any difference in spdif_io between audigy2 and audigy2 zs ?

**dj_stick** · Aug 9, 2004, 10:02 PM

external COAX is not of TTL levels, which are required by the AD_EXT and SPDIF_IO headers on the audigy 2, use the CD_SPDIF header for this purpose

exorcism · Aug 10, 2004, 07:30 PM

So I bought this Audigy 2 ZS sound card and found out that the digital output on the back is not really "SPDIF" or something, certantly only outputs stereo to my nice surround receiver.

I called and asked them about this and they said I'll only get surround with dvd's with the rear output, and that if I got the Platinum the SPDIF/Toslink out on the front-panel would allow me to play all my games in surround over the digital connection.

I'm wondering if this is true or not, and if so is it possible to use the spdif pinouts on the board to do this rather than buying the Platinum?

Big problem here is the Audigy 2 ZS has almost no low-end to it's analog outputs and the bass boost they so proudly advertise only works in 4.x/2.x mode (not 5.1+ mode) so that further causes problems to my sound. The analog sound from the card just isn't that good, and certantly doesn't come close to my external receiver. It's very disapointing really.

it is S/PDIF and definately not surround
here is why

tay714man · Aug 13, 2004, 06:20 PM

Hi, I have a cooler master cavalier case with front headphone/microphone jacks. I'm trying to get my audigy 2 to connect to them. I had the front connections working fine on my onboard sound, but the connectors I have are too big for the pins on the white J1 connector on the card. Does anyone know if there is a way I can connect the jacks without just cutting ends off and connecting the wires directly to the pins? Is there a place I can get one of those white connectors?

CVNet1 · Aug 22, 2004, 01:05 AM

Hey all, I'm new to the forums (joined so I could post here), so if this has been covered somewhere else, please just direct me there. I was looking at connecting the front panel audio to my Audigy1 card and from reading everywhere I understand that its not possible to do with the pinouts on the card as they are a digital connection vs the analog. However I noticed on the back of the soundcard where your audio out connectors are, there are very short pins which stick out from the audio headers and are sauldered at their base to
