Default Balance control

BOSOZ:

I would like a balance control. However my skills in electronics are poor, and I'm not sure if I can manage to implement this circuit at output p4 without risk of higher output impedance:
http://sound.westhost.com/project01.htm
...so I though off using an alternative (my Bosoz is unbalanced only):

1. Use my two-channel attenuator 5K @P4 as master volume.
2. Use two one-channel 10K pots @P1 as input gain, thus being able to adjust balance.

The reason for this is that I prefer only one master volume control (P4).

Please comment.

I use 10K linear pots with resitor as you showed in the link to get 5K in the output.

promitheus, thanks for the info :-)
You use 10K linear as bal and 10K linear as vol?
Which value for R did you use to get 5K total?
Did you use the switch?

I only have volume control. The problem is i forgot what resistor I used and itīs not so easy to see anymore.
I will take a look later and tell you.
To make it balanced I use a system I bought from www.thel.de to control 2 stereo pots with mechanical junction.

For output P4 with balance control I've decided to make the above circuit using:

Volumen: 5K log stepped attenuator
Balance: 10K lin pot
R = 0,47 * 5K ~ 2K32
