AKG C12VR Large Diaphragm Tube Condenser Microphone

Production of the legendary C 12 ceased in 1963, and over the years, it became a highly sought-after collector’s item and prized recording instrument because of its exquisite sound. The new C 12 VR is a reincarnation of this spectacular microphone. The new C 12VR is true to the original C 12’s acoustical specifications with subtle refinements made possible by modern electronics and manufacturing technology. These refinements actually lower susceptibility to hum and noise as well as improve its ruggedness. The two 1-inch capsules are identical in performance to the original design with the famous AKG “voice-friendly” sound. The electronics section uses the same rare 6072 vacuum tube as the original to ensure the C 12 VR will deliver the trademark warmth, clarity and presence that characterized the original model. Nine different polar patterns are remotely selectable from the N 12 VR power supply. Other features include two bass roll-off filters (also remotely selectable), switchable pre-attenuation pads and an internally selectable +10 dB input sensitivity switch. The large core-section output transformer minimizes low-frequency distortion and special shock-mounting protects the circuitry and provides acoustic isolation. The C 12 VR comes in a special hard-shell metal case housing the microphone, its power supply, the shock mount, windscreen and a 10 m (33 ft) connecting cable. A copy of the frequency response graph is included along with the three-year warranty. Add magic to your sound with the AKG C 12 VR.
