Does anyone have the iPhone LOD pinout? - Page 17

So...noob question but I knew that the sound gods here could answer this question:

When using a shielded cable (Like a Mogami or a Canare starquad) are you soldering the shield at both ends, ie. Dock Connector and 3.5mm plug, or leaving one floating?

The reason I ask is because common procedure is to leave the shield floating at the amp end, but I didn't know if it makes much difference for the length of this cable and it's application.

You terminate the shield at one end when making unbalanced connections, but in balanced TRS connections, the shield also carries audio information (on the gnd wire) so you definitely want that soldered at either end as well.

Does the line-in (pins 5,6) work this way?

I have an old FM transmitter for my iPod that I have used for, oh, the last six years or so. The connector needs replacement, and I have finally gotten the replacement part in from SparkFun. The transmitter is sufficiently old that it does not work for iPads and iPhones, so in the process I will be attempting an upgrade with the 68k resistor on P21.

 

Will post back with photos when finished.

I would be curious if this same configuration would work for the iPods as well (e.g. if you make for the iPhone it works for both, but not if you make just for iPod)

I was wondering the same thing a kojl. If these pins work and we short them with the ground we could make the smae remote as on the headphones. Also does this cable allow you to take phone calls

I ordered some 1/8 watt 68k's will they work? I've seen a lot of people running around with large resistors and I'm not sure if I have enough wattage on mine.

Don't worry. It's enough.

Awesome. Is 3.5mm large compared to the pins on a LOD? I was hopping I could make it fit between pins 11 and 21 rather than making it bend back around.
