The Apple diyMod: My Take on the Famous iMod [56k killer] Featuring 3G, 4G, 5G and nano 1G! - Page 188

post #2806 of 3003

 

I have one 5.5 with faulty amp. Using direct out with z caps removed - Lod is clean.

But headphone out has crosstalk and noise. Is there a way to completely disable internal headphone amp? Which components have to be removed? Signal route...

This may be a longshot, but I have a question on diymodding an iriver h120 and h320.

 

I want to mod the line out on both, and would prefer to use external coupling capacitors for the sake of easy experimentation with different caps. With the internal circuitry of the irivers, is it a viable option to short the pads for the stock capacitors and use capacitors after the 3.5mm line out?

 

The reason I ask is because I don't know if there's internal circuitry after the capacitors that depends on DC offset being blocked. I will likely find out once I open my players for inspection but wanted to throw this out there.

Should be shipping with the ALO LOD. biggrin.gif biggrin.gif Can't wait to hear it. Should be here in two weeks. Going to be pairing it with my Fiio E17 and DT 880 250ohm cans biggrin.gif

I had also modded the iMod with the CF adaptor, 128GB SD card, new battery, (highest capacity I could find) and a clear front faceplate.

Should definitely be a unique iPod/setup. biggrin.gif That email just made my day.

Would love to see pictures and impressions.

I'm planning to sell most of my Imods. Too many...

Long time since I've been on here...

 

Don't forget guys that with certain designs of amp you can DC couple your amp/iMod without using caps

Especially on a portable rig that uses separate batteries.

I had mine running that way for over a year but installed caps so I could use it on other devices.

Do you mean that certain amps have coupling capacitors on their analog inputs? This is definitely true for some amps. The amps I have (RSA Tomahawk and Meier 2move) do not, so I'll need to use caps no matter what.

 

Though if your portable amp already has them, by all means it's better to not add anything additional in the chain.

I did all my imods this way. Have used caps in lod cables (not always easy to fit).

Hi buddy

Yes and No ....

Yes, if your amp has input caps you can omit them in the iMod but you can also couple certain amps by putting the negative rail at the same DC potential to prevent it from flowing down the signal path.. Look at the datasheet of the DAC for DC Coupling schematic.

I'm hosting a sale today at RetroSonicFidelity, for those of you that don't want to build the diyMods yourself.  I have a 3G touchwheel, a couple minis, and some standard (non-modded) minis.

 

I'll be doing another sale on Black Friday weekend, but I figured I'd let you folks know about today's sale, if you don't want to go buy a soldering iron, caps, wire, etc.

Any pointers to a micro electronics repair shop on london that might help me with this? I have experinece with things like this but this one is really small for my eyes!

Don't get me wrong, it's all about ability and finance...... but this is a DIY thread ;-)

 

... and I'm going to comment on 'that' level of modification... sorry, can't hold myself back

A simple (and not very tidy) bypass rewire for that price is utterly ridiculous.

I would (and did for some time) supply fully bypassed modifications (DAC to Pins) for a fraction of the price.

And that included internal caps..

 

Huge apologies for my outburst

Standing down off my soapbox

 

Bye
