TVC is better but is limited in the number of steps and is very difficult to make. 
Everyone wanted more steps in the volume control so for the Libra we chose resistors but they are AFTER the gain stage so we do not loose any of the input signal!!

On Libra ALL attenuation is after the gain stage! 
It is labeled input or output just so you can have a meaningful reference to what you are doing.

Input level attenuation is used so you get more or less the same usable volume levels among your sources. Output level is to compensate for the power amplifier gain again so you have more or less the same settings for different equipment.

Input level attenuation is used so that you get more or less the same usable volume levels across your sources. The output level is used to re-compensate the gain of the power amplifier so that you have more or less the same settings for different equipment

Hello Rumen,

thank you for the answer.

I understand that the attenuation of each input is done to balance the different sources
For optimum rendering: Do I understand that there is no preference between strongly attenuating the source or rather attenuating in the Libra 300?

Patrick

No preference it is the same. It is up to you for user convenience
