  • Audio Out for Eumig 824 Sonomatic

    Hi all.

    I'd like to connect a Eumig 824 to an amplifier/speaker setup like I have for my Elmos. Unfortunately, Eumig used a less conventional connection (see photo; audio in is on the left and audio out is on the right). I've also included photo of the specs for the audio out section.
    Do any of you more tech-minded folks have a suggestion for an adaptor that can plug into this and connect to one of the more standard audio inputs (1/4" line in, 3.5mm, even XLR)?

    Thanks in advance for any advice.

    Ethan, those are standard DIN plugs. You can make your own DIN patch cord.

      Hi Ethan,

      I have exactly what you are looking for, but only because I made it myself. I bought a cable with the correct DIN plug to mate with the projector and on the other end I soldered a 1/4" TRS plug (-usually called a "stereo phono plug") in a balanced connection to plug into my mixer.

      Where this gets tricky is the Eumig's line level output has about 50,000 Ohms impedance compared to the Elmo's 600 Ohms. When you plug this 50,000 ohms into your 10,000 Ohm amplifier input, you lose a lot of signal strength (down to 1/6 of what you started with, actually). My mixer's balanced inputs are something like 24000 Ohms, so even though I'm still losing most of the signal, it's not so weak I can't compensate with the volume knob.

        This what you need. You can connect your own wiring.

          Thanks all. I'm a neophyte when it comes to creating my own wiring. Are DIN 5-pin all the same or do I need to look for something with specific terminal connections? I imagine this is probably far easier in reality than in theory, but I want to be sure I'm getting the proper materials before I start cutting and soldering.

            Hi Ethan. I suspect this will give you what you need. It certainly works with my Bauer 610.

              The diagram you have in your post shows which pins go to which wire. The DIN's are all the same, but can be wired differantly, depending on the application. Pay attention to polarity.

                INACCURATE!
                Dins ARE NOT all the same. There are many variations of Din plug. 2 3 4 5 6 7 8 pins in a variety of configurations. The one you need as used on the Eumig is a 5 pin Din 180° which is quite common. There is also a 5 pin Din 240° which you DO NOT want. If you Google 5 pin Din 180° wiring you will see the pin config numbers.
                You can get pre wired breakouts, like the one Stuart posted and then you simply work out which of the two phonos you need. If you are really not up to making one maybe one of your US colleagues can come to your rescue.

                  Hi!
                  David is correct: There are many different „DIN plugs“. That’s because DIN is the German equivalent to ANSI, ISO, … (DIN = Deutsche IndustrieNorm = German Industry Standard). E.g. a piece of paper that is only a little bit larger than „letter size“ is „DIN A4“.
                  If you need more information: https://en.wikipedia.org/wiki/DIN_connector

                  Even though the numeration of the pins and the dimensions of the plug are standardized, the usage of the pins isn’t standardized. The most common layout for „audio out“ is:
                  Pin 2 = Ground
                  Pin 3 = left channel (or mono)
                  Pin 5 = right channel (unused when mono)
                  Pins 1 and 4 are usually unused.
                  But there’s no warranty for this, especially when it’s an Austrian projector.

                    There is a schematic within the Eumig 810 manual in the FilmTech warehouse that confirms Pin 3 as signal "hot" and Pin 2 as chassis ground. I'd be really surprised if the 824 was any different. This is what I went by when I made my cable and it's fine.

                    See .pdf page 23

                      Guys, please read all the posts before commenting on a single post. The first response I posted (#2) included a link to the detailed wiki on DIN plug types.

                        Pins 2 and 3 are confirmed by Ethan's enclosure of part of the instructions for line output.

                          True, but for some reason Eumig didn't state the hot and ground. Being that there is a 50,000 Ohm impedance in the way it's not going to blow up anything, but if you swapped them into a grounded input the signal would disappear.

                            Thanks again everyone. Two followup questions--
                            1) Terminals 2 and 3 are what I would connect wiring to. Based on Joerg and Steve's posts, it looks like terminal 3 carries the audio but only Left channel/mono. Does that mean there would be no output from the balance stripe on Super 8 if it's a stereo print? (Disclaimer--I only use this projector for Standard 8, but I figure it doesn't hurt to understand the techie side for future reference.)
                            2) Steve--if I understand your first post correctly (with the info provided by others), you bought a cable with a 5 pin DIN 180 already wired to terminals 2 and 3. Then you soldered that to a 1/4" TRS plug. Is that correct? Also, any advice on shielding that area at the end of the cable where it gets attached to the 1/4"?

                              So why then confuse the o/p by stating "Din's are all the same" ? Given that he was less than familiar with them, it was at best misleading.
