Creative Audigy 2 AD_EXT pin assignment

**dj_stick** · Jul 26, 2004, 04:38 PM

yes this is what it doesâ€¦
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 :-

thanks for this information, this will help some users greatly

FROM WHEREEEE???

**dj_stick** · Aug 2, 2004, 05:05 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

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, 04:05 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, 04:10 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
