Default Is my LT44 transformer suitable for audio (de)coupling?

One more thing - the Neve mic pre has a pretty poor noise performance.
At -128dBu equivalent at the input, that is about 6dB above pure
thermal noise. That is 4 or 5 dB more noise than they should be
achieving.


Please do your sums properly Don before making gaffes like that !


Thank you! I did make a gaffe.



** A *****ing stupid* one.

Like hundreds of others and another one, right now !


The actual figure for the Neve noise
figure is about 3dB.



** The published curve shows it is typically less than 2 dB.


That is still unforgivably poor for high end kit
- it is in fact no better than my little Behringer.



** It is SFA additional noise in practice.

PLUS none at all when a typical condenser mic is used, as is the norm.



Ten years ago I
was designing satellite receivers working up at 12GHz.



** Who gives a rat's **** ?

Go stick you irrelevant & erroneous RF ****e up you ****ing ARSE !

You are NOTHING but a trouble making, posturing, pommy

ARROGANT PIG - Don Pearce.



The last audio preamp I made had a noise figure of about 0.5dB,



** Bet the ASININE ****WIT matched the source and load impedances.

Then miscalculated the **REAL** noise figure.

ROTFLMAO !!!
