Left/Right Channel balancer

[JoeB83]

Hi all,

I'm wondering how one would go about making a left/right channel balancer. I have about 10% hearing loss in my right ear which makes listening with headphones rather difficult, if not annoying. I currently use an O2 amp, Shure SRH840 cans, and either an iPod with line out or connected to my computer via an ODAC. The only way I can realistically change this with the equipment I have now is if I change the balance through the 'sound mixer menu' on the computer. I was thinking a 1K ohm trim pot on each channel would do the trick, would that work well enough?

How are the O2's gain resistors configured? You could increase the gain for your right ear to get a perceptual balance. The gain pushbutton could then be an "equal balance" or "compensated" switch.

That's a wonderful idea, it never would have crossed my mind! I'm using the default values for the gain resistors (1K & 274R). How would I calculate which values I should use? Or should I just start changing the resistors about 10R at a time until I reach the balance I want?

Yes, trial and error substitution would be the best way. Use of the gain resistor sockets is a real help here. It might be a good idea to give a relatively lengthy audition to each change to make sure you get a comfortable long-term fix.
