Are there passive attenuators that don't zero volume and only offer one input ?


I am not sure how many people would like those features, but its worth asking in case someone would try to sell such a thing.

Which is to say it is essential I should think  to be able to zero volume, and have more than one input, do you agree ?

Rectification can then be achieved with thyristors, and jfets
¿Que?

Thyristor is a gated diode. What earthly advantage is there over a 1N400x diode?

 Look inside the plugpack  , it explains why they are 10 a penny.

"A thyristor is a semiconductor device which can be used to switch current on and off. When used in rectifier circuits, thyristors allow current to be controlled more accurately than diodes, which can only be ON or OFF. A thyristor can be triggered to allow current to pass in a graduated manner, by firing (switching on the thyristor) at a precise time, therefore controlling the conduction angle."

What about using those keyboard fingers instead, to design your product so that it can have more than one input, and can have silence at zero volume, ... a far better use of your time I should think.
