"The level of the channel that is not being turned down does not change."
That's some pretty good magic!
A voltage divider with 250k as the series resistor and 500k as the shunt resistor will have 2/3 of the input voltage at the output. A voltage divider with 250k as the series resistor and 750k as the shunt resistor will have 3/4 of the input voltage at the output.
