Hello, I noticed there has been some updating of the Cracks FAQ one of the things that caught my eye was a change in recommendation on how to attenuate the signal to the Cracks pot from the 270k resistors placed inline at the L&R RCA inputs end to a new method that switches to resistors at the pot end.
I am curious to gain a better understanding of advantages the new method of attenuation compared to the old solution?
If anyone can spare a couple off minutes to shed a little light on this it would be appreciated.
Thanks,
Jamie

The old method would drop the voltage at the RCA inputs and then a lower voltage would travel through the braided wire to the volume control. The new method leaves the full signal traveling through the braided wire and drops the voltage at the volume control.
The signal is less susceptible to noise going through the braided wire at a higher signal level.
At least that is the way I see it.
