C 747


  • Slim design
  • Extended bass and high-end response
  • Hypercardioid polar pattern
  • High SPL capability

    • The C 747 is a tiny shotgun microphone designed for exacting orchestral, choir, podium, and boardroom applications. Flat, extended frequency response makes it suitable for high quality live music recording, while the frequency-independent pattern provides consistent off-axis rejection to control ambient noise and feedback in acoustically difficult environments. A switchable LF rolloff filter suppresses mechanical noise. The low-impedance transformerless preamp operates on 9 to 52 V phantom power. Standard accessories include a shock mount/adapter, mini gooseneck, stand adapter, mounting clamp, thread link, and windscreen.
