It's a sony meter I have a feeling it's from an old Sony betacam deck.

An audio signal generator?

 

Hello,

Yes, eric is right.
You can test and calibrate it with a known signal from an audio signal generator.

I have 2 signal generators

Whirlwind Qbox

and a Shure one

Both are XLR how can I wire it?

That's the first thing I tried hooking it up to my Qbox but nothing.

 

Hello,

Do you have the manual of the Qbox ?
It says the signal comes from 1 and 2 of the XRL plug.

And pin 1 is return or ground but still nothing not even at +4db
