Topic: Transformer preference... Audio Technica CP8201 vs Hosa MIT 176?

oops Chris, your last posting was 'empty', quotes only

just got a reply from the 'boss',

I don't think a transformer is going to be a solution.  The best place
to use a transformer is between the microphone and the pre amp. This
way you get gain without increase in noise.  Unfortunately this circuit has a low input impedance around 600 ohms.
The article states that you could use a 1:1 transformer but this will not help the gain.  I would have
recommended our type 4935 but this has to feed a high impedance e.g.30 K ohms. It will not work
feeding into a 600 ohm load.

I am sure there are other pre amps you could make which could be used
with 4935

aarrgh...

What type of preamp are you using? if its high impedance then you can use a transformer if its low impedance you need a low impedance transformer.

well, it's my DIY preamp http://sound.westhost.com/project13.htm resp. http://taperssection.com/index.php?topic=71782.0;all

I just received my much delayed SP-CMC4s and hurray, the level is with them is much higher than with my AT822, so there is no more need for more gain!

( though I'd have loved to make a mixer to mix both mics, using a second of the same preamp to have the same preamp for all 4 channels, but then I'd have to lower the gain of the SP-CMC4s to the - 'unsatisfactory level' of the AT822. Therefore I'll still try to improove to preamp, there are some ideas, if successful I'll report at my DIY preamp thread )
