I've plugged the NT4, with the dual XLR cable, into my
Edirol FA66 with phantom power on, and messed with the
gain etc but nothing much is happening. I only get an
extremely quiet and bad quality signal from it with the
gain on full.

Maybe my FA66 is quiet? With gain half way up, speaking
at normal volume about 6 inches away from a Neumann
TLM103 the levels read somewhere around -24 on average.

"Gain half way up" is kind of arbitrary, but I'd expect
that this is about normal sensitivity for a TLM103 at an
unknown gain setting. I would expect sensitivity of the
NT4 to be in the same ballpark. If the TLM103 works, that
means you're getting phantom power.

I've never worked with *any* Neumann, but the NT4 sensitivity is in the same
range as most SD condenser mics. The NT4 is mostly just 2 NT5 cardioid
capsules packaged together with a built-inoptional battery box.

First thing I'd do is verify that the NT4 actually works.

Ditto for the FA66.

Find a mixer or another mic preamp that you can test it
with. You didn't blow up the mic by pugging it in with
the gain up, and if the TLM103 still works, you didn't
damage the input of the FA66.

Agreed.

One possibility is that the FA66 isn't supplying
sufficient phantom power for the mic.

Unlikely. I've used a NT4 with a Microtrack, and I've used it with the
Behringer mixer with optional battery power (on batteries). My take is that
the 9 volt built-in optional battery is all the NT4 needs. IOW, a NT4 might
work well with even 12 volt phantom. I know it works with the 24-ish volts
from the little Behr mixer.
