AKG Acoustics C 12VR User Manual

C 12 VR

Tube Condenser Microphone

Description

The AKG C 12 VR (Vintage Reissue) is the modern
equivalent to the classic C 12 produced beginning in 1953.
The C 12 VR continues to set the standard for quality,
providing its famed warmth and presence, which are direct
results of its unique tube (6072), diaphragm and transformer
design. Internal microphone switching is provided for pre­attenuation of -10 dB, -20 dB, and +10 dB boost. The
available pick up patterns include omnidirectional, cardioid,
and figure-eight with six intermediate patterns. The nine
remotely selectable pickup patterns make the C 12 VR a
necessity not only for vocals, but for instrumental solo
recording, as well.

The C 12 VR comes with its own professional flight case,
power supply (N 12 VR), elastic suspension (H 15/T), 30 ft.
multi-conductor connecting cable (MK 12 VR), and foam
windscreen (W 42).
