I have the Eumig Mark-S 710D and wondered about the plugs. There's a two pin in the main speaker and a din plug in the projector. Are these all the same on all Eumig sound projectors. Does anyone know where to get such plugs?

Thank you

Posted by Maurizio Di Cintio (Member # 144) on November 24, 2012, 02:29 AM:

Well... They are usually availale in stores selling electronic components, at least here in Italy. Are they so hard to come by in Norway?

Posted by Vidar Olavesen (Member # 3354) on November 24, 2012, 02:43 AM:

I think so, old stuff just doesn't get kept here.

Any chance of picking up a couple for me? Would be nice with two pairs and also for the Elmo ST-800

I'd pay all shipping costs and all and you tell me what you want for the trouble?

Thanks

Vidar.
You can buy them off Amazon and need to look for

'2 Pin DIN Speaker Plug'

Ok, thanks, what about the output plug from the Eumig?

Posted by Vidar Olavesen (Member # 3354) on November 24, 2012, 05:22 AM:

Super, but that's the 2 pin only ... I do need the Eumig plug too and hopefully the schematics is available?

Posted by Maurice Leakey (Member # 916) on November 24, 2012, 06:00 AM:

Are you referring to the 3 pin plug?

Posted by Vidar Olavesen (Member # 3354) on November 24, 2012, 11:22 AM:

Probably ... Will check my projector and see. Thanks for the links

Nope, checked and it look like 5 pin, anyone know for sure? Eumig Mark-S 710D

Anyone have the pin outs? It seems like 5 pins, but maybe only three connected ... What is the third for, if it's two in the speaker only?

Posted by Maurizio Di Cintio (Member # 144) on November 24, 2012, 12:36 PM:

Indeed usually only three are connected.
Glad to supply you all you need but first check out as suggested.

Good luck

Posted by Vidar Olavesen (Member # 3354) on November 24, 2012, 12:53 PM:

I can't be 100% sure, there are five holes, but looks like only three connected. Would that mean the right 3 are the ones from the link above? What pin does what? I thought you only needed ground and (I don't know this in english, but the other one with the signal on it). What is the 3rd for? And which is which?

Posted by Martin Jones (Member # 1163) on November 24, 2012, 01:58 PM:

Yes, it's right, you only need a 3 pin one. A 3 pin DIN plug will fit in a 5 pin socket, but not a 5 pin into a 3 pin!.
The centre pin is "ground". The other two are for INPUT and OUTPUT, equivalent to LINE IN and LINE OUT with RCA sockets on amplifiers: if you haven't got the instruction book you find out which is which by trial and error.

Posted by Vidar Olavesen (Member # 3354) on November 24, 2012, 02:13 PM:

No chaance of killing the projector completely if I try?

I understand that three pins would it, but are they in the right pin holes? I will try this, thank you ...

Posted by Martin Jones (Member # 1163) on November 24, 2012, 04:54 PM:

They will only fit one way... and no danger to the projector at all
(unless you try to put mains in there instead of at the back!).

Hate those DIN plugs. My GS1200 uses them for the speakers. One flat one round. Cheap and nasty in my opinion. Just like the scart for video crap [Big Grin]

Deutsches Institut für Normung e.V. (DIN; in English, the German Institute for Standardization). Standardisation is OK in some ways I suppose, but when the committees try to make a standard the best may not be the one that wins.

The 3 pin ones must be for mono in/out, 5 pin for stereo in/out. I hated to wire them. RCA were a lot better I think?

You could try Maplin or Farnell for them too.

Posted by Maurizio Di Cintio (Member # 144) on November 25, 2012, 02:52 AM:

I'm not 100% positive your DIN socket is for both input and output: I have an 804 with a three pin DIN socket: the center one is the ground and the other two are for mic or line input. But this is easy to cjeck: put the DIN plug "naked", i.e. without sleeves, shield etc and solder the ground; then switch on the projector and put it in rec mode; link the other end of the cable you are building into any audio source (keep the volume low) and use either one the two pins to check if you are getting any sound in the projector: once you can hear a good quality sound, without excessive leve (distotorted) then that's the pin you want.

If you just want to connect a loudspeaker you only need to use the DIN socket at the rear of the projector, this uses the two pinned plug, one pin is round, the other is flat.

If you want to feed out a signal to an amplifier you need to connect to the right-hand side DIN socket. This is a 5 pin socket but will accept a 3 pin plug. Only two connections are used.

See my new posting about DIN plugs and connections for Eumig.

If you do not have an instruction book, this Forum has a free down load for the Eumig 810. Whilst this is a later projector than yours it will give you some very useful information.

Posted by Vidar Olavesen (Member # 3354) on November 25, 2012, 04:51 AM:

Thank you. There's no such plug on the rear of my projector, it has a mini jack though ... Same?

I'll give it a go and order a couple of them ... I only want to connect for now, to the speaker case following the projector to get the sound from the front instead of behind me ...

Thanks again guys

Posted by Maurice Leakey (Member # 916) on November 25, 2012, 06:24 AM:

I have no data on your model, but I have a Eumig 709.

Just looked at the projector and see that it has a mini jack socket in the middle of the rear panel (near the speaker), this however, is the earphone socket.

The speaker socket on my 709 is over to the right as you look at the projector facing the speaker.

Damn, tried ordering the two pin speaker connectors, but they won't ship to Norway :-(

Bought the 3 pin ones though

Try this ebay seller who will ship to Norway for £2.49.

I have about three black DIN two pin speaker plugs. they are brand new...let me know if you are interested...

Posted by Vidar Olavesen (Member # 3354) on November 25, 2012, 03:23 PM:

Maurice, thanks, already done it :-) I searched eBay for 2 pin speaker and that particular item came up ... Thanks though

I want to connect my Eumig 810D to external speakers. Will this 5-pin DIN to mini jack work? http://www.ebay.com/itm/5-Pin-Din-Plug-To-3-5mm-Jack-Stereo-Plug-Audio-Cable-/190718066187?pt=US_Audio_Cables_Adapters&hash=item2c67aebe0b

Posted by Jean-Marc Toussaint (Member # 270) on March 20, 2013, 06:44 AM:

Janice, the two 5-pin din sockets at the front are for "aux. in" (near the record level button) and "aux. out" (near the front of the machine). You will need to find a cable/adapter to connect the "aux. out" to a phono line in (usually RCA connectors) of an amplifier, to which your speaker will be connected.
If you just need an extra speaker, use the two pin (one flat, one round) socket at the back of the projector with a plug similar to the one described by Maurice in the above post.

Posted by Maurice Leakey (Member # 916) on March 21, 2013, 03:35 AM:

Janice

Have you got an Instruction Manual for the Eumig 810D? If not, you can download a copy from the Film-Tech site.

The "External Speaker Socket" is shown at position "11" on the rear panel.

You will need a "DIN" speaker plug. This has two pins, one small round and a larger flat, i.e., it will only fit one way.

Posted by Janice Glesser (Member # 2758) on March 21, 2013, 02:17 PM:

Yes, I have the manual Maurice and I've located the socket on the back. It's more a matter of getting the correct 2-DIN plug with attached cord. I've only been able to locate the plug itself with no cord attached. The link I referenced above is a 5-DIN plug that I can connect to the AUX-OUT on the front and it has a mini plug connector which with plug adapters would work for me....but will this channel the audio out to a peripheral device like a recorder or speaker? ...or is the 2 pin DIN on the back the only viable source?

my eumig came with this 3 prong adaptor

Posted by Janice Glesser (Member # 2758) on March 21, 2013, 07:19 PM:

Thanks Jim for the photo...I couldn't find a 3-pin DIN to RCA cable..but I found a 5 pin...will this work?

Hi Janice,

My experience with Eumigs and amplifiers is they aren't grounded very well and can produce some spectacular hum when connected to an external amp.

If you plug yours in, stick a meter on the case and measure like a volt AC to house ground, you have one of these!

Posted by Maurice Leakey (Member # 916) on March 22, 2013, 04:08 AM:

Janice

Do you want to connect direct to a speaker? Or do you want to connect to an amplifier for ultimate output to its speaker/s?

The earlier Eumigs are prone to hum, and as Steve said the latter idea will only amplify the hum. It's best to go direct from the external speaker socket as I said before.

Most DIN speaker plugs are usually sold just as the plug, the idea is that the user will connect a suitable lead. Here is a link to a UK seller who will sell to the US. The tags have a screw connection for the wires. The plugs simply pull apart to make the connections.

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=190815204645

If you refer to page 15 of the manual you will see details of connecting to item 28 (Line Output). Note that the socket is five pin, however a three pin plug will connect OK. 3-pin were used for mono connections, and 5-pin had the added pins for stereo.

If you wish to consider using the Line Output I suggest you use the following:

http://www.ebay.com/itm/1-2m-5-Pin-Male-Din-Plug-4-x-RCA-Phono-Male-Plugs-Audio-Cable-006109-/200832692802?pt=US_Audio_Cables_Adapters&hash=item2ec28fb242

A little trial and error will produce the required result. The end connections may not fit your amplifier, but no doubt you could provide suitable plugs. But, as previously said, such a connection may increase the hum.

By the time the 900 series were produced Eumig did seem to have sorted out their hum problem.

Janice, I have a Eumig 810D and the external Speaker socket is on the back of the projector and is a 2pin DIN speaker socket as already described so you need a 2 pin DIN speaker plug connected to the speaker lead. I prefer to use the Line Out Socket which is the 5pin DIN socket at the bottom right hand corner of the front operating side of the projector marked with a triangle, and feed the signal into a spare channel of my Yamaha AV amplifier.

Posted by Bruce Wright (Member # 2793) on March 25, 2013, 09:58 PM:

Here's my take on the audio output. I have an ELMO ST-1200HD
and a EUMIG MARK S 810D. The ELMO came with the sc-002 adapter
cable. It's about 7 inches long with a small flat pin / round
pin on one end and a 1/4 female plug on the other. This cable
fits both projectors. Went to Radio Shack, got a 1\4 inch male/
female Y adapter. Plus two 1/4 male plugs and 32 ft. of speaker wire. Split the wire apart, attached the plugs, connected the
other ends to a pair of 8 ohm speakers. THE SOUND OF MUSIC
