There is only one logical way to connect the first two resistors, and

the point of including the third 10k resistor?



To provide some attenuation to get the 2V rms output closer to the 0.5V
rms input requirement.


If the idea is to prevent overload of the amplifier then the shunt resistor
should be a lot lower, 1.67k to be exact.

David.



The idea is not to prevent overload but rather to get the power amp volume control in more user
friendly region.
