Need small simple mike-to-line preamp
Hi;
I just bought a Sony Discman audio recorder, then discovered my electret mike does not have enough voltage output do effectively record live music. It only has line inputs. I ran around to various electronic stores and music stores but could not find a mike preamp. Probably 20 db voltage gain would be sufficient. The only thing I could find was a prepackaged phone to line level converter, which is NOT suffiicient, since it has the RIAA EQ curve. I need something with a FLAT response. They do have those monster rack-mountable preamps that take an XLR balanced input, but those are overkill, considering that they cost $500-600. Ideally, what I would like is a little box about the size of a deck of playing cards, perhaps battery powered, that will give me a stereo voltage gain of 20 db or more. Adjustable input gain would be nice. Have any of you seen something resembling that? Otherwise I could buy an audio IC and fudge up something in my garage, but I'd rather plunk down some $$$ and save myself the labor. Thanks for any suggestions; Bill Sinclair |

Thanks for any suggestions; Bill Sinclair Radio Design Labs makes a line of "Stick-Ons", little boxes that do a single job. One of those boxes is a mic preamp (STM-1). Find the whole line at Markertek.com he http://www.markertek.com/MTStore/lis...io+Design+Labs Another source. Look he http://www.denecke.com/prod04.htm |
