Profile the additional gadget, then de-convolve its properties from the overall properties with gadget and device-under-test.

Of the amplifier you need!

Amplifying 5 to 50V is very different from amplifying 0.5V to 5V even though the gain is the same.

The DUT input impedance is important because it determines the power you need on the amplifier output (apart from the signal level).

Edit: spelling it out

I would probably need a maximum of 10db of gain so something like 7Vrms to 24Vrms I suppose

Well, the point is to be able to test various DUTs, isn't it?   :) Pro audio gear Input impedance can range from 200Ohm all the way to 1Mohm with 600, 10K and 100K being some of the most common values.

Ideally, I was hoping to find an off the shelf solution.

Because I could not find such a thing, I built one.

What are you using it with? QA403?
