Title: Cheap preamp solution for core sound cardioids?
Post by: smat on June 15, 2008, 03:13:18 PM

I wanted to re visit getting a preamp to boost the base and presence of these little mics.  I just want a simple boost.  Any suggestions on what would be the cheapest and best way to go here??

I ran a Denecke AD-20 in front of my Core Sound Binaurals for a little while and I liked the results very much.  You should be able to find a good condition used one for not a whole lot of money.  I think I paid like $250 or $300 for mine new about 10 years ago.

Maybe try a Church Audio ST-9100?  Sounds good and it's pretty inexpensive.  I have never used it with the Core Sound mics, though.

Line transformers like these two provide cheap gain... I've run the MIT-156 before and recall it sounding pretty good and adding in the 10-15 db range (can't remember the exact amount it increased).

AFAIK a XFMR is passive impedance matcher, No gain is produced, but loss can be minimized.

I'm leaning towards the church audio.  What's the difference between the 9000, 9100 and the 20B?

when I owned some of these mics, I went Core Sound Cards > cs bb > SP-PREAMP > deck, and got fine results.

of course substituting the Church pre in that chain can also be done.

FWIW, the SP-PREAMP is just a tad smaller then the Church pre's

Simply put: the ST-9100 is the latest version, best Church preamp. I love mine. ;)

I'm sure Chris will chime in, but I believe the 9100 has variable gain up to +20db while the 9000 has only three gain settings, +10db(?), 0 and -10db.  I think  8)

I may be wrong, but I think the ST-9000 has gain settings of 0, +10 dB, and +30 dB.  And output level control...I don't know anything about the 20B.
