Help asked for Elma A47 attenuator mono's instalation!

[simsalabim]

Hi Folks,

hope you can help me!

Some time ago i bought Glasshouse attenuator mono from Hificollective, which is the Elma A47.
I opted for the 0,25w carbon takman and Zfoil.

they came pre installed, however i do not understand why the 'in' is not used..

So this is how it is hooked up:

ground: to ground
out: a z foil resistor and the output signal.
now the part i find odd:
on the out is also the z foil resistor and then the input.

So the input signal goes through the z foil to the output of the A47 and the output (attenuated) is also on the output...

is this because of some reason? a mod e.g.?
got me baffled, strange thing is, it does work this way.

help and or clarification would be much appreciated!!!

So i.e. only the out is used for signal.. i still find this strange, espescially as it seems to work...
What is going on here... 😉

I figured it out, it is correct as this is in shunt config!
