Can I tweak L-R balance by differntial biasing?

I've found that the best way to do accomplish this without a balance control is to move the speakers. You can very accurately, and in whatever incriment you desire, shift the balance just by moving the desired channel either closer or further away. Image is a little shifted right, just move the right speaker 1/2 to an inch further way from you. Try it. You might be surprised how well it works.

I'll tell you what Dennis Had told me: "Move your chair", but that is easier said than done, especially if you don't have a dedicated listening room.

I agree with the Almarg....

Depending on how "desperate" you are I see four possibilities.

1) Try Rrog's ideal of changing your room. (Probably the hardest to do if a relationship is involved).

2) Add a preamp with balance control. (Probably the hardest on the finances).

3) Add a voltage divider network just before the volume control on the channel that you wish to lower. (Probably the most time consuming).

4) Have your integrated modified to have either left and right volume controls or adding a balance pot. (Definitely the most trouble to restore to original operation).

Practically speaking, kiss channel balance goodbye if you want to use bias as a 'balance' control as you've described it. By rendering channels 'unequal' in regards to signal level, all you will accomplish is the destruction of the stereo image, ie: point source imaging, depth, extension, and low level resolution. You will have the exact same issue you started with, only worse, much worse. A balance control is an attenuator, not a signal reduction.

Mezmo- Great idea. It works!!!
