volume controller scheme for computer output

[papacharly1963]

I need a simple diagram of a volume controller, using a double sliding potentiometer. I need to connect the headphone output of a computer to its input. It is important that the output is balanced, to be connected to 2 active speakers with XLR input.
I don't know if it is possible to make this circuit in passive mode. This would be perfect.

Thank you. Passive volume control with a quality transformer requires a high price. I think the option will be active. But you would need a complete balanced output circuit.
