I have the stepped attenuator shown in the attached images.
It is my understanding that I could create a passive level control with it, with some connectors, wiring, a box and a knob.
Is that true?
If so, how would the wiring be done?
Thanks,
Bruce

if i'm not mistaken, thats a four channel elma attenuator with smd resistors, a great piece, what application are planning it for?

The topic of the thread is about the idea of using it to create a passive level line-level control.... Is it simple, and how can it be done?

I apologize if I offended thee.
I am just wanting to confirm if it is even possible to add a few parts to make a simple monitor controller.
Not sure what else to say to describe the "application".

Monitor controller, well, that would be the "application". There could be several other uses for a line level attenuator, e.g. between a pre and following gear to drive the pre into saturation and several other tasks...
So, in principle, yes, just wire it up with the connectors and put it in a nice box. Depending on which resistor values have been used, you can change the attenuation characteristics also with parallel or serial resistors (resistor network rules)...

...thats a four channel elma attenuator... Makes me wonder why the Equinox needed a four channel vs a 2 channel attenuator. I suppose that for my purpose, I'll only use 2 of the channels. Any ideas on how to make best use of the other two? btw... I ran across this, which seems to spell out fairly well what the wiring would be like: I figure I might just get a nice 2U panel to build this on, instead of a "table-top", unless you guyz have a source for nice boxes with wood ends? |

4 ch attenuater = 2 ch balanced attenuater.

Beware that they place a significant demand on the line amp that is driving them and its power supply.

So, I'm thinking if I don't build something with that switch, I might sell it -- any idea what they might be worth?
