Which type of attenuator (L, T, Pi) and resistor values ...
https://www.diyaudio.com/community/threads/which-type-of-attenuator-l-t-pi-and-resistor-values.343158/
I am looking for a 12 - 16db level of attenuation. Which type of attenuator should I use, L, T or Pi? What values of resistors should I use for 12b and 16db. I would prefer the attenuator to go between the dac and preamp so that when using headphones I can still turn up the preamp/headphone amp past 10 o'clock.

The table in the figure below lists resistor values for the T and Π attenuators to match a 50 Ω source/ load, as is the usual requirement in radio frequency work. Telephone utility and other audio work often requires matching to 600 Ω. Multiply all R values by the ratio (600/50) to correct for 600 Ω matching. Multiplying by 75/50 would ...
