pls help..............................

hi, i just found an old inear stuff, philips SHN2500, in a box left in my storeroom. It still works well but i see that It doest have portability with a small size amplifier sticking with the cable. I want to separate the amplifier by taking out the plug and headfone wires and solder some female...

does it affect sound quality since no resistor added ? im wondering how i can add a mic line in through that, im using ipod touch G1

hi bro, wat is the function of a resistor there for ? reducing noise?

  Quote: but for 1 driver, there re 2 wires out + and - label, which one is considered the signal wire to be added resistors ??

yea...the result now is 60 ohms.....haha..my drivers have not gone wrong yet........................

Quote: yes i did bro, using FLUKE 117 to measure numbers............both sides are 32 ohms so what does it say ???

  Quote: hi bro......the value of left driver was shown at 32 ohms, same as right driver value of 32 ohms..... can I conclude that the left driver does not have any problem ???

  Quote: hi.... been searching but seen now repose of how to make a DIY piece of impedane adapter 100 Ohm....plz give me some instruction

thx bro....any further recommendation plz.....

1.hi, just as a new DIYer, I want  my new porta pro to be improved in sound quality by adding series of 75 Ohm high quality resistors but facing several questions :   _ how many resistors should i add in ( using ipod touch and ipod video to play ) ? _ how should i solder those resistors to...

thx bro.....finally done after 3 hours........never soldered b4,great result...

hi, my new porta pro standard plug was just broken out and I already bought a new Neutrik angel plug ready for soldering....but I am not sure about sequence of wires in both channels, what wire should go for what pole........right channel cable : 3 wires of green, blue, little blue   vs left...
