Ah, a xformer! If it is not a 1:1 ratio (used merely for isolation), I
hope the *low* side of the given ratio of your device is used at the
*mic* end (ergo it steps up into channel i/p). So if it's about 1:3.2,
can we rename it a 10dB Dab?

If it is a transformer, I'd guess it's for matching a high impedance
dynamic mic (Shure make these) to a low impedance input.

Or, indeed, the other way round.

Something like 7:1.
