5 pin Din plug to 2XRCA

I built one like the title says, but the signal is so weak that it is only moderately loud, not pounding like the deck & radio. I have the iPod volume turned all the way up, and the Tele, too. I got the pin-out from a European parts house's web page. With the cast mark on the plug at the top like it should be, the pins are arrayed along the bottom of the plug left to right as follows:

3,5,2,4,1

pin 3,right RCA in +
pin 5, left RCA in +
pin 2, Grd
pin 4, line out, not used
pin 1, line out, not used

Both RCA shells are grounded to pin 2

Before I troubleshoot the circuit in the radio, have done something stupid first that was really simple? I ask this because the pin-out in the Telefunken schematics is drawn different it seems. With the cast at the top, the pins are ordered 1,4,2,5,3. In other words, backwards from the way I thought it should be. Am I just looking at it reversed (view from behind) or is the first one wrong? :huh: The socket number is BU 302 in the schematics.

It's been a long day. Screwing up is easy to do. :bang:

Maybe our European members can slap me upside the head here for a little bit of percussion maintenance. :blush: Which is right? Or are they both right, just different views? I did some searching on line and it seems the first is what I run into, but sometimes with a little capacitance or resistance thrown in to grd. That doesn't work for me.

Sure sounds sweet, just not as loud as I would like it. :rock:

Hold on, your DIN plug goes into TWO RCA's? So then you must have to connect that to another cable with 2 female RCA's that merge into a single RCA for your iPod.

You should get a DIN plug that simply goes into one RCA, like I have, which works great.

Everytime I need cables like this, I buy them from Ebay member lazerwave. Here is an example:

Actually, the second cable is a 2X female RCA that with a 1/8 in plug on the other end for the iPod. I just needed a 5 pin din to 2X male RCA.

I used to make these for tape to tape recording years ago when the only box I had was my OG GF-9090 from Europe. This should work & I didn't want to wait for one to be shipped to me for 15$-next-week-delivery.

Works great. Just not loud enough.

Thanks for the link. Just ordered w/ free shipping and Mon. delivery

This pos should still work.

Yes, I believe you are piggy backing off of the outputs & have it reversed. If you plug an Ipod or any source into the outputs, you will still get a muted signal to the pre-stage of the blaster. Most work this way & the sound will be much lower & have a smaller dynamic range & freq. response too, sometimes...

Try the other 2 pins & I bet it'll kick in good...


Or you could buy a proper DIN to RCA adapter cable that is pro made & well shielded & performs better than anytning you could fab at home....

I always find that the sensitivity of 5 Din units is much lower than the RCA versions. My Hitachi TRK-5140E with 5 Din inputs sounds very quiet on line in compared with my Hitachi TRK-5150 with RCA inputs.

I purchased two of these 5 DIN to RCA adapters but only my Sanyo M4500K with 5 DIN inputs has a sufficiently sensitive circuit to make it usable with an MP3 players. I tend to avoid 5 DIN boxes for this reason.

I have an AIWA 990 & am waiting for a din cable to arrive so I can test line-in. If what you say is true, that kind of sucks. That would mean the gain on the pre-in side is lower for DIN than RCA standards?

Man, I hope your 990 rocks the house down when your cable arrives.

I know the sensitivity issue doesn't seem to affect every model but a European M90 I recently heard with a 5 DIN input was super quiet (useless) when hooked up to an MP3 player. We had to use the phono inputs with an attenuator to get some volume happening.

:hmmm:
Excuse the obvious comment here, but why not just buy a DIN to 1/8" stereo headphone lead and use that? I do this to play stuff from my HOX on the Hackers and other radios I have with no RCA connections and it works fine. As a comparison, I tested the DIN lead against the RCA-to-1/8" one that I also use, using the JVC PC-5 because it has both RCA and DIN I/O sockets. Level is comparable between the two standards as it should be, there being a good 2mV of overlap in the specs. ;-)

@ James: The M70 that I recently rebuilt for a member had the same problem as you described, but there's more than enough adjustment at the relevant VRs on the I/O board's preamp so I'd hazard a guess that the M90 is the same that way.

Hmmmm..... That's good to know. Any chance of a pic of the VRs to adjust?

The box is currently with a colleague of mine who's delivering it by hand to the owner when she goes home to France for the Christmas break, she's based at the Mother campus and I'm rarely there but I'll see what I can do, worst case scenario; I'll point the VRs out on the circuit diagram and post that here when I have a few minutes to myself. :-)

But bear in mind that this is an M70 and I have no way of knowing whether the M90 is the same in this respect, though I do think it's reasonable to assume that it should be.

You hit the nail right on the head. Switched 'em up and everything rocks. :rock: Thanks for the nice slap upside the head, everybody. I couldn't have this radio rockin' without the chime-ins from all the members that make this such a great place.

I did order one at a great price from Hans' link, with free shipping. Like I said earlier, I saw the price at another place w/ next week delivery & didn't want to wait. Took 10 minutes to build & a couple to fix. eBay wouldn't take my PayPal info last night and It took 3 tries to get it ordered, so it took me about the same amount of time to order as it did to build a nice long one.

I was tired last night. When I get tired, I get impatient.

Can't wait to get home after work tonight and play with the Tele some more.

Now, everything works. Now while I have it open, I'll start troubleshooting the other one. Maybe if Scott kept and want's to trade or sell his parts, hmmmmm, twins! Either way, I'll have a second, too.

I found out which pin corresponds to which line, when I made a DIN to 4 RCA (In and Out lines).

I traced the ground pin from the Schematic and then connected all other 4 pins to 4 RCA sockets with common ground. Then traced which is Left/Right and In/Out by trial and error with a very low level signal playing! No guess work and positive result!

Good to know of this source. I still use the split to rca ends. The 3.5mm right angle looks more effective.
