Attenuator pads as shown above can be used for any signal, audio, video, RF.
In the Pi network, Rp1 and Rp2 will have the same value
In the T network, Rs1 and Rs2 will have the same value.
For any given line impedance Z (more correctly Zo = Characteristic impedance)
the values selected for the 3 resistors will give xx dB of attenuation.
A number of www sites have online attenuator calculators
