Avantone Pro CK-6 Series Transformer-less Condenser Microphone

CK-6 is a cardioid true condenser built on a transformer-less circuit with a single-sided 30 mm center-terminated gold-sputtered Mylar capsule. Frequency response runs 35 Hz to 20 kHz +/- 3.5 dB, with an 80 Hz high-pass filter and -10 dB attenuation switch handling close-miked and loud sources up to 136 dB SPL.

CK-6 Plus swaps in a larger 32 mm capsule and adds a retro shockmount, a carrying pouch, a foam-lined steel mic case, and a wooden storage box, all in a white foam gift box, over the Classic's included accessories. Both take standard 48 V phantom power at 5 mA and output on a 3-pin male XLR.
