pico itx question

chris350 · 06-09-2009, 07:29 PM

ok, so im still working on my set up and I have a pico itx system. Now i've seen that the pico can do 4 channel audio output as well as 5.1 or more..I would like to know where can i get the cables to get at least 4 channel audio. cause everything on a pico board is connected by pin headers. I got the manual and understand it somewhat, but where do I get the pin header cables, its an aritgo kit thats doing 2 channel sounds now

so my two questions are
Where do i get that pin header cable?
and
is it worth to do 4 channel audio or just split the two channels into 4 cause im am going to use an amplified system set up.?

on VIA Arena site they have kit with enclosure and it has all calbes you need for extra $200, or otherwise go to Mouser Electronix and get yourself 3mm pin connectors ( i think thats 3 mm)

as to aydio thats all depand on ur amp
if ur amp is 2 channels thaen u need stereo source if its 4 ch thehn u do w/ 4 sources

Thanks. I will check both out. My amp is a 4 channel amp.

then go w/ 4 ch
also ast to pins just take a ruler and measure the distance between pins and thats tipe of connector u need.

thanks. I will have to check the pins. does anyone know what the difference is when connection the cables? which is ground..AGN or the other one?

whats your model #?
You can go to Via Arena site and find all info about your board

chris350 · 07-02-2009, 07:33 PM

its the pico itx 10000...the 1GHZ version.

i have the manual that describes all of it. but there is two grounds that i can see...one is AGND and the other is just GND

tempgp · 07-02-2009, 07:46 PM

i cant find that model

under pico
but for 700 model here is a linnk, u need User Manual - Pin Assigment document

ok on the page u have me click downloads and at the bottom u will se User Manual, go to page #23. There us a pinout for your Audio and manual is self explanatory. If u use 4ch then u use Line out L/R connected to GRD and Suround L/R each connected to ground

u may also want to use ferrite rig to reduce noice is you are not using spdif

@chris350
How did you go ?

I'm doing a pico system now with dual 2-channel amps (Front L/R + Rear L/R) and also wanting to find header cables for the 4-channel output.
I'll actually configure the system for 5.1 so I will have the sub channel ready for later.

My understanding is that the AGND is used for the audio channels and the GND is used for the spdif.

The correct socket pitch for VIA Nano/Pico boards is 2mm not 3. Standard headers are 2.54mm

Thanks, already know that.
What I am trying to find is any ready-made header cables for the 16pin audio connector.
I can get the separate plug and crimped cores, but they are industrial quantities, not singles.

out of my memory go to viaarea website, go to pico section then somweher is the link on redistributor who sales casings, they also have all type of premade cables
