How do I do that?Could you measure the gain of both channels?
How do I do that?
Not sure it is exactly correct, but I do this way:
Input - 1kHz sine wave. Output - 8Ohm resistor, about 2.83VAC. Compare input AC voltage to output AC voltage and you will have gain at 1kHz, 1W.
simple programs , free from net , will do that
all you need is any sort of computer with even crudest sound card
quality isn't important

This one seems to work but has no sweep function:
