Guest Da5id Posted August 28, 2003 Report Share Posted August 28, 2003 OK, just tried the tarballed version of eagle, and it worked.Got the files opened, and shit, I can't wait to get started!Kind of drives me nuts in a way, this interfacing seems so simple once I look at it, but I just didn't know how to do it on my own!I really need to study some EE (Electrical Engineering) and really get a grasp on these things, I love all of it, I need to truly undersand it.Thanks again!

pilo Posted August 28, 2003 Report Share Posted August 28, 2003 hehe ;)the PCB is simple! except the Small SO package :-/I think when we finished the design of the board, I can make some board with the pcm solder on it, this way it will be easier!

LO Posted August 29, 2003 Report Share Posted August 29, 2003 if the optical out is and SPDIF, then it's "easy" to make a spdif input to your amp! see this link : http://sound.westhost.com/project85.htmThanks for this tip however it is only to Stereo & not 5.1There is a mention of modifing it to work with DTS but thats probably a bit beyond me :'(Thanks againLO Quote Link to comment Share on other sites More sharing options...
uclaros Posted August 29, 2003 Author Report Share Posted August 29, 2003 I know it's quite newbee question, but how can I connect an unbalanced output (mono) to the balanced input provided by the ADC?? Quote Link to comment Share on other sites More sharing options...
pilo Posted August 29, 2003 Report Share Posted August 29, 2003 you can put the -input and GND togehter, and the +input with the signal of the unbalenced :) I make this to test the board and it's work ;) Quote Link to comment Share on other sites More sharing options...
drumwide Posted August 31, 2003 Report Share Posted August 31, 2003 hey you guys are awesome, I've been researching parts and stuff to build a cheap adc possibly to adat interface.And I check in on the midibox site and its been here all along.Anyway I was wondering if you all could let me know where to get the eagle files talked about earlier in this thread. And any text info I can dl.I am not a programmer or an engineer but only a musician on a budget, with a will to learn.Any thing I might can help you all with let me know. Testing or anything. I am purchasing Sblive cards as I am writing this via ebay.So can I get 8 dig. i/o per card or 16? Also is the highest resolution 16/44.1 or 24/96?Thanks and I look forward to (hopefully) contributing something to this project. ;D ;D ;D ;D :-X Quote Link to comment Share on other sites More sharing options...
pilo Posted August 31, 2003 Report Share Posted August 31, 2003 I'm going to work on the website this afternood! so I will put the eagle file on it!FOr the quality, I read that the emu10k1 can handle 24bit/48kHz data... I don't know how this is handle on the driver side...There is 14 mono inputs, but we will use only 8. And I think 14 outputs (1 I2S, 4 SPDIF...have to check this) ;) Quote Link to comment Share on other sites More sharing options...
drumwide Posted August 31, 2003 Report Share Posted August 31, 2003 great...be sure and post the web address asap...oh yeah...What is I2S? Quote Link to comment Share on other sites More sharing options...

drumwide Posted September 2, 2003 Report Share Posted September 2, 2003 Thanks so much, gillesdeshays. I appreciate you guys taking time to answer my, newbie, questions.You all have helped me so much too understand more about electronics,programming,analog and digital audio. I hope someday I can return the favor.keep up the good work ;D Quote Link to comment Share on other sites More sharing options...

d2k Posted September 3, 2003 Report Share Posted September 3, 2003 heyhey...A little update, i etched the quad ADC brd Pilo and Smash put together and I stuffed 2 of the 4 PCM chips. Needless to say they work :)Great work fellaz, this is gonna expand into one mighty project I can see :)I wonder if we could ever get near to apogee conversion quality somehow - obviously not with these 10k chips but mebbe sum1 has a few tricks up they're sleeve :PBestDan Quote Link to comment Share on other sites More sharing options...
Frank Posted September 4, 2003 Report Share Posted September 4, 2003 Here's a link to a supplier of TOSLINK tx and rx modules for ADAT lightpipehttp://www.sysconcept.ca/product_info.php?cPath=34&products_id=157peaceFrank Quote Link to comment Share on other sites More sharing options...
drumwide Posted September 4, 2003 Report Share Posted September 4, 2003 Hey Dan, where did you get the scematics and layouts for the quad adc. I'm dying to have a go at it, and my sb live will be here in a few days. 8) Quote Link to comment Share on other sites More sharing options...
pilo Posted September 4, 2003 Report Share Posted September 4, 2003 I can send you the file, but I think before more people make it, dan should test it with 4 ADC, and see if everything is fine. I'm going to make mine soon, so I can test it too ;) Quote Link to comment Share on other sites More sharing options...
drumwide Posted September 4, 2003 Report Share Posted September 4, 2003 hey thanks pilo, go ahead and send it ot me so I can start getting parts ready and when I see everything is ok I'll build.I will send you a private message with my email addresss.thanks again.Maybe i can help test it.

d2k Posted September 4, 2003 Report Share Posted September 4, 2003 Hey ppl....3rd PCM added and working :) I dont have any more to test with now tho :/...BTW, for toslink connectors I got a cpl from this place:http://www.cooltronix.com/shop/index.htmlBestDan Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted September 4, 2003 Report Share Posted September 4, 2003 Hey D2K !make some picture of the quad ADC ! ;DPilo : what about ya website ? 8)I had an idea for the "Octo ADC DAC" .... something modular ... in a little rack .....with internal power supply or external .... and some modules (1*2 Ch ADC, 1*2 Ch DAC, ADAT, SPDIF converter .....What do you think about that ?Personal message: Sorry i have many problems with my internet connexion since 1 week ..... but you can reach me by mail ........

pilo Posted September 4, 2003 Report Share Posted September 4, 2003 hehe GREAT!!!nice to see you back Gilles!!!!!look at the RME ADI converter... maybe we can have something like that (have to work on the s/mux thing, but I know how we can make that with cheap component... need to read some book)... Well... if anyone wants to help with the web site, no problem :) Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted September 5, 2003 Report Share Posted September 5, 2003 Well... if anyone wants to help with the web site, no problem :)i'm here Pilo ! ;)We have to see if my modular idea can be interresting enough ! My idea is to create a simple rack which can be upgrade with some modules ... For all : please gimme your felling about that ..... Quote Link to comment Share on other sites More sharing options...
d2k Posted September 5, 2003 Report Share Posted September 5, 2003 Hey Gilles!yeah, i'm down with the modular idea :) so we can use an external rackmount box and connect it to the sblive via a 25pin D type cable...PeeshDan Quote Link to comment Share on other sites More sharing options...
pilo Posted September 5, 2003 Report Share Posted September 5, 2003 yes!!! modules!!!! hehe!!! I think it will be the more interesting way for every body!!!! :)yes I know, I should be sleeping... :D Quote Link to comment Share on other sites More sharing options...
Guest Da5id Posted September 5, 2003 Report Share Posted September 5, 2003 For the external rack, what were you thinking for interconnect? Going to try something with ADAT format lightpipe, or 4x i2c lines, or what? Quote Link to comment Share on other sites More sharing options...
pilo Posted September 5, 2003 Report Share Posted September 5, 2003 for the external Rack : ADAT lightpipe and CAT5 (RJ45) cable ;) this is an idea from SmashTV and I think it may be a very interesting one! But you can have both adat lighpipe and CAT5 cable :)Maybe other output like TDIF?and analog ouput :) we have to work on the DAC board :)But any idea are welcome!I think the only thing important here is that we many people intersted in it! can't do this alone!! :)thanks all!! :D Quote Link to comment Share on other sites More sharing options...
gillesdeshays Posted September 6, 2003 Report Share Posted September 6, 2003 exactly Pilo !all of you are invited to give us idea !for the Boox to PC connexion I was thinking of a SUD 25 ...the cheaper solution ! but i have to make some test to see if it's ok with spdif + i²s in a simple multiwire + shield cable ......Other think .....i think it's better to use i²S outputs the the SPDIF .... so priority to I²S ... post here ALL your suggestions ... even if it seems to be crazy .... ;) Quote Link to comment Share on other sites More sharing options...
