I was going to build an adapter and realized I didn't know which resistors to use, does anyone have suggestions which and where to get them? I think I want 75 ohms. I just connect one on each signal channel correct?

I did the same thing with my Freqshow, soldering the 75ohm resistors onto my cable and terminated it with a neutrik plug. I used 1/4w resistors, that is all I could find here in Hong Kong, 1/8w(even smaller) will work as well. The 1/4w was a perfect fit inside the right angle Neutrik.

 

[AudioNoob]

so is there a polarity to the resistors for this?

 

[QQQ]

^^no.
Regarding wattage, use the biggest you can fit into plug or wherever you're outting them into.

Considering that the sensitivity of the ER4s is 106 dB @ 1mW, you'll be bleeding from your ears before you get to 1/8 W. I doubt that there are many headphones that draw more that 1/4 W and for the few that do, you won't need an impedance adapter.

Not at all. Unless you're OCD like me and line up all the colors across several resistors.

I probably am

, oh and I was getting it for my superfreqs to use with laptop and while flying overseas, those airline amps pack a punch

.

So Is there an online store that I can get them from with envelope shipping? I'm looking for metal film resistors 1/8-1/4W 75ohm correct?

I'd just go to Radio Shack and buy an inexpensive DMM and more than 2 resistors while you're at it. You'll need to match the resistors no matter where you get them from, unless you spend a lot of money to buy very high tolerance resistors.

Yep, metal film resistors in 1/8 or 1/4wattage. I'm actually using 100ohm resistors in my Freqshows right now, eliminates all noise from my Blackberry Bold(noisiest thing ever).

If you're still in Rochester (Mass right?) I'd try Mouser or Digikey if you want an online store.

Radioshack is just as good but you want the DMM to match resistors no matter where you buy them from.
