Yep, that's it. The resistor and capacitor in that circuit are not

you would just connect your source directly into the + input of the

R and L are the subwoofer outputs of your crossover.
The fancy way would replace the two 1kOhm resistors with, say, 47kOhm,
and insert an active buffer circuit between the Y and the subwoof

and allows you to present a higher (more friendly) load impedance to
your preamp.

Hi Andy,
Would you be willing to share the script you are using to do a batch

If jitter at the data input of a circuit influences the timing of the
output data, then something is corrupting the clock -- excessive
impedance in the power and ground planes, bad signal routing, poor
