Retro Look, Modern Circuitry
The A77Bk is a faithful recreation of the classic Astatic A77, with the same timeless style of the original, except for an elegant midnight black finish. CAD chose to update the circuitry for it's 65th anniversary, including a high gauss neodymium magnet and a TrueFlex diaphragm. The update brings modern performance and results in a hot and articulate acoustic profile.
Ideal Applications
With a high max SPL of 150 dB, the A77Bk can be used on loud sound sources without worry, and the high sensitivity makes it quite effective for recording voices whether for talking or singing. Some of the primary applications in which this microphone has been designed for include:

  • Live vocals
  • Studio vocals
  • Acoustic guitar
  • Percussion instruments
  • Voiceovers
  • Broadcast/Podcast

The CAD A77Bk Large-Diaphragm Dynamic Microphone not only looks great but also sounds fantastic. It's an excellent addition for any live performer. Kudos to B&H for delivering the mic on time as promised. I’m impressed with the CAD mic and equally satisfied with B&H’s reliable service. Both are solid and trustworthy!
