Hi!
I want to make stepped mic pre input pad using bridge T attenuator. Seems to be a good idea. But what kind?
This type of attenuators are used in many classic amplifiers like Sta-level, UA176... 1176 uses this type of attenuator at the input before the input transformer. But all of these devices use a bridge T attenuator. But bridge T attenuator is an unbalanced attenuator, if it's right to say. So attenuation became only on hot wire, right? Is it so unfundamentally?
Where it could be more suitable to use bridge T and where Balanced Bridge T attenuators?
