Planned to develop analogue input modules for 10k1 and 10k2 cards

Mac Daddy · Mar 10, 2009, 11:45 PM

I agree with the front panel hookups that's the reason we bought the Aud 1 back in the day for the studio .. the live drive

On jacks 1/4 inch and RCA's here as well but I have adapters for everything here so I am flexible.

I would also vote for front mounting.

Projects like this I would mount in an old CD ROM drive with the guts taken out...

This is a nifty little idea Tyrsonswood. I must have 2 or 3 old CD-ROM drives that I have pulled out of computers because they started going south.

I also have leftover mounting trays from old 5-1/4" floppy drives that could be modified to house the project.

1/4 jacks sounds good.

TravelRec. · Mar 11, 2009, 07:35 AM

Okay,

so I think 1/4" jacks are quite big in size - in the best case your card has 3x I2S, then you will need 6 of them in a row or 3 pairs in two rows. This makes the design of the single A/D modules a bit harder and the PCBs are much bigger then. I doubt they all can fit in an old CD_ROM or a drive slot. Additionally: each A/D module has a complete stereo converter, so 2 jacks must be mounted or wired on/to each module. Hmm - first I thought, stereo 1/8" (3.5mm) sockets would be fine since they are very small, common for soundcards and available with a fixing screw, so the socket can hold the complete A/D-module on the front plate, so no other fixing is necessary. And it is possible to combine the A/D-modules with optical interfaces for SPDIF I/O, that can also be conected to the header adapter pcb on the soundcard. So you can mix all the different inputs/outputs you need and that are available on AUD_EXT // AD_EXT.

And for the analogue shielded cable wiring inside the computer: I would say 'NO'.

Mac Daddy · Mar 11, 2009, 10:49 AM

Well considering the space concerns on the front panel 1/8 inch jacks can easily be adapted to 1/4 inch anyway (and RCA) ... both adapters are quite common.

very nice travelrec. to give a comment to case- solution: i would prefer an external breakout- box, which can placed everywhere.

you shurely have some practice in doing pcb boards. lightning, timing, etching.. is a trying task. it's been a long time since i have done this. could you doing such pcb board(s) for a fair price? soldering, also the smd, is no problem (for me).

Hi all,

have done some prototyping. On the pics you can see a hub, that routes the AUD_EXT signals to 10 different headers, 3x SPDIF in / 3x SPDIF out / 3x I2S in / MIDI#2 I/O. The hub pcb has also a spare AUD_EXT 1:1 wired through. The hub fits directly on the cards AUD_EXT header. On the pics you can also see a single SPDIF input module with an optical receiver, connected via 6-pole flat ribbon cable to one of the hub headers.

To stylus02: PCB etching and drilling is no problem - since you are located in germany I can send you pcbs. For the breakout box I think, this will be more tricky than some internal modules, since the high frequency digital signals have to go over longer distances and so some (differential) drivers must be used to stabilize the signals. I don´t say that it´s impossible, but it will be a harder piece of work.

Mac Daddy · Mar 13, 2009, 12:59 AM

Nice work and too stylus02 I agree on the difficulties with the breakout box.

Looking good here and in Canada so can't offer any direct help but have done all the things aforementioned.

Hi,

short report: 3 independent ADC-modules are running successfully on the CT4760, turning it into a real 8 analogue input card including Line in

. Some fine-tuning with the components and the routing card has to be done, then all will be fine. MIDI is working too. Etched SPDIF-modules are the next step, TORX/TOTX 178/179 optical devices are used first. Other devices with different pinouts follow later.

Cool stuff man keep us posted

Doug W · Mar 18, 2009, 11:54 PM

Go TravelRec Go!!!!!

TravelRec. · Mar 19, 2009, 06:48 PM

Okay here I go

All modules that can be connected to the CT4760 are running now, 2x SPDIF_in and 3x SPDIF_out, so 12x input in summary and 10x out - all fully accessible via ProFX. I think, this is the limit with the 11y old soundcard. I will post final layouts and pictures within next week.

This is what I was talking about, Dj ..... the cable connector is there for the IO module you mentioned, marked digital I/O. But next to the AUD_EXT connector is an AUD_EXT_2 connector. My Audigy drive has the pads there, un-populated, but this live drive SB0010C I just got in has the pins and looks fully populated. Documentation only says "future expansion" ...... I can't find anything else on the net about what they planned for this.

Not meaning to steal the thread, TravelRec, but it did come up here.

For your information: the schematics, layouts and some documentations and pictures are updated as often as I have time on kX-project support site by TravelRec. -> Electronics. Questions and suggestions are welcome.

Tyrsonswood · Apr 7, 2009, 05:50 PM

Nice work, did you take down your other electronics projects? I just see the new one.

TravelRec. · Apr 9, 2009, 07:31 AM

Yes, the other projects are a bit outdated and the site will be updated with newer stuff.
