AKG CK 1 and CK 8



Description and Applications

This microphone considers new and future oriented technologies. The microphone meets the highest technical standards and will withstand rough handling in studio applications. Special attention has been paid with these microphones to the complete linear transfer characteristics of all transmission parameters. The low inherent self-noise and the high overload point guarantee a dynamic range of these microphones in the order of 120 dB, which is substantially more than figures found in conventional microphones and other associated equipment. The outstanding technical performance is also achieved with all practical loading conditions of different input circuits of associated equipment including the often necessary long cable runs.

Product Features

  • Ultra low noise figure (14 dB-A ENL)
  • Extremely low distortion (from 30 Hz to 20,000 Hz)
  • Low power consumption (less than 1 mA)
  • ∼15mm active diaphragm diameter for a good balance between low self-noise and the acoustic properties
  • Smooth roll-off at both ends of the audio range for good phase response
  • Carefully designed output stage for driving any load right down to almost “zero impedance” of long cable runs without detectable deterioration of the output signal
  • Constant output impedance over the entire audio range
  • To be powered from any standard phantom powering source (acc. to DIN 45596)

Description and Applications

The AKG CK 8 is a short shotgun of highly stable performance. As a result of combining the gradient and interference principles, it has a frequency-independent characteristic and features a narrow angle of acceptance. Its medium-distance reach makes for a clear emphasis on the desired sound sources.

Together with FET preamplifier C 451 or C 452, the CK 8 is highly suitable for television and film soundtrack recording, for stage use, reporting and field work as well as for multi-track recording studios where good instrument separation is desired without acoustical screening of performers.

Since the distance between the diaphragm and the sound entrance is relatively great in the CK 8, vocalists on stage can use it rather close to the mouth without creating pop effects.
