Okay, so I'm not an electrical engineer. Listed below is an accurate accounting of my stupidity. Please help. I am trying to create a line in/line out device with faders for the purpose of attenuation of an incoming signal. Kind of like a mixer, but without any extraneous stuff such as Pres, sends, returns, etc. Simply line in --> Attenuation --> Line out. So, is it this simple?: Hook the three-pole input jack up to a Penny + Giles Fader (or rotary attenuator) using hot and neutral (the faders are only 2 pole) and then pass the output of the hot and neutral out to the output connector along with the straight wire from the cold from the input? If it's really that easy, I'll be making it real soon. Input anyone??
