Digging In to Atmosphere
The KAM Atmosphere is a small-diaphragm condenser microphone sharing an exterior with the KAM RT1, a dynamic vocal microphone previously reviewed here. The interior circuitry is comprised of an advantage 4-transistor FET preamp section.

While the Atmosphere is built like a tank, the true test of this stellar microphone is sound quality. Used on instruments, the KAM Atmosphere has an absolutely silky smooth sound signature. I've tried the KAM Atmosphere on high-hat, overheads, guitar cabs, and on percussion, and I've been very surprised every time. Cymbals come through with a brilliant presence; percussion cuts and displays both body and attack; on guitars, it sounds best with warmer blues-style amps, but when matched with the right amp, the sound is phenomenal.
Performance on instruments aside, the KAM Atmosphere shines on vocals, especially female. The mids are present but not over-pronounced, low end tight yet airy and natural, and the highs present but not brittle. On male vocals, the Atmosphere worked incredibly, although I tended to prefer it better for female vocalists.
The KAM Atmosphere is available now, and can be ordered directly from KAM Instruments' Website, or ordered from their eBay store. It's retail price is $159.
