The CK-6 Classic in its normal stock version uses high grade Polystyrene and Metalized Polypropylene capacitors in the audio path. This represents our commitment to quality as these normally are the type of "upgrade" components that are implemented by microphone modders/hot-rodders! Any studio can proudly offer the CK-6 Classic for instrumental and vocal miking. It exudes class visually as well as sonically. Manufactured using the finest materials yielding a very solid feel, superb structural integrity and rugged reliability. The versatile CK-6 Classic mic is able to produce professional results with a clean sonic character. The included Custom Retro Shockmount is superb in allowing a precise positioning of the mic while inhibiting the transfer of unwanted vibrations up into the mic. This isolation allows for superior professional results. The CK-6 Classic has separate -10 dB pad & 80 Hz LF roll off switches....The -10dB attenuation switch can be engaged when miking very high SPL sources to keep from overloading the electronics. The 80Hz high-pass filter switch can be engaged to reduce rumble and to keep unwanted low frequencies from "muddying up" the track.
