        Hi Steve,

        No, I am all out of circuit boards for the Delta 44 interface module and probably will not order any additional boards.  I could change my mind if I see there is enough interest in the kit.

        73,

          I've made a couple (without the filtering) using old sound cards.
          They usually have a 15 pin socket and 4 stereo sockets.
          I removed the 15 pin socket, cut the board square around the 4 sockets, removing any components then drilled it for refitting the 15
          pin opposite the stereo sockets. Then wired them together with self-fluxing enamelled wire, spare from a Softrock kit.
          They look very much like Tony's.
          Well.... you probably think I'm crazy!

                Sid, We are talking about Tony's replacement for the D44 breakout box which has eight 1/4 inch jacks.
                The interface is here http://groups.yahoo.com/group/softrock40/files/%27A1%20Delta%2044%20interface%20module/ The filtering is LC.
                If one is reproducing Tony's box it not a bad idea to include this, it could be done with discrete components. I did not include
                filtering, I do not TX much, it is not included in the original box and does not seem to be a feature of other cards. Of course,
                none are specified for use with a TX!
                My crazy comment was to acknowledge that many on the group would not wish to use my crude technique because they want their work to
                look as good as it performs!

                  Alan et all, I received my brand new Delta 44 PCI card and matching Break out box from my local store in Newcastle yesterday but have not had a chance to install it yet. Although I already have one of Tony's Breakout boxes which I will eventually use, I have two questions which I hope someone out there might be able to answer.

                  Firstly, when I opened up and looked inside the supplied M Audio Delta 44 Breakout Box I noticed that if a 1/4 inch mono jackplug is inserted in any of the four outputs then the tip of each is individually decoupled to its sleeve via 130 ohm resistors in series with 22 uF electrolytic capacitors, also the four inputs are likewise decoupled with 10 Kilohm reistors in series with 22 uF capacitors. But what I found was strange was that the Positive lead of each electrolytic fitted had been wired to sleeve (ground). Whilst presumably no DC voltages should ever be present in service and hence no need to observe convention, I nevertheless wondered why they are wired this way, other than by mistake, or does anyone no different.

                  Secondly, on my PCI card marked M-AUDIO DELTA Revision D, date of manufacture week 37, year 2008, I noticed that near to where the Xtals are mounted and the ICEnsemble codec is situated there are pads for a resistor marked R6 which in my board has not been fitted. This if fitted would have resistively connected pin 52 of the codec chip to ground, so again I am wondering why this is so ?
                  If anyone out there who has a board can take a look at theirs and satisfy my curiosity and eliminate any fears about my board's integrity before I install it I would be obliged.

                  Many thanks es 73 de Charles G3OTH

                    I realise these components are to make the input (appear?) balanced but would like someone to explain how. As you say the +ve of the
                    capacitors is grounded. These are not relevant if the input is unbalanced.

                    The board is probably used for other applications where this is inserted. Many electronic assemblies are designed to facilitate
                    various features. A computer or satellite receiver, for example, may have a large number of "missing" components.
                    I have a vandalised breakout box but all my D44s are installed but I doubt there is any reason for you to worry.

                      Alan thanks for getting back to me.

                      On closer examination having looked inside the Breakout box again I realise that I should have said that the capacitor and resistor networks act as series AC coupling between the sleeve of each jack and common of each pair of channels, rather than as decoupling as I had implied. They are actually brought into circuit using the ring connectors of the Stereo Jack sockets utilised in the Breakout box which make contact to the sleeves of the Mono Jack plugs when inserted. I had confused the tip for the ring in my previous message. It still does not explain however why the positive of the electrolytics are wired to the commons.

                      As far as the "missing" R6 is concerned on my Delta 44 PCI board is concerned, I singled this out as it seemed to me to be intended to be to do with the codec as everything else in this immediate area is populated. Admittedly there are other large areas of the pcb where other IC, capacitor and resistor legends are not populated, these presumably are intended for other applications for this board, but as these were not part of the immediate circuitry surrounding the codec I ignored them.

                      I wonder if anyone knows if a schematic of the Delta 44, or for that matter, any sound card, exists in the public domain to which I could refer, for the purpose of general interest and as to how they function?

                        I have acquired a Delta-44 sound card and would like to have an interface module as supplied by Tony. After writing to Tony to see if he was going to have more (they are still listed on his site) I found his answer from last August, saying were not available at that time.

                        If Tony is going to produce more I would wait for him. Otherwise,
                        does anyone have one for sale?

                        I would pay using PayPal if reasonably priced.

                          Hello Group

                          I have acquired a Delta-44 sound card and would like to have an interface module as supplied by Tony. After writing to Tony to see if he was going to have more (they are still listed on his site) I found his answer from last August, saying were not available at that time.

                          If Tony is going to produce more I would wait for him. Otherwise,
                          does anyone have one for sale?

                          I would pay using PayPal if reasonably priced.
