BidirectionalPearl Microphone Laboratory CB 22

Bidirectional Condenser Microphone

The CB 22 is a FET condenser microphone with Pearl’s Model 2800 rectangular dual-diaphragm capsule, configured for a figure-of-8 pickup pattern.

The Model 2800 capsule uses a thin polyester diaphragm measuring 14x29mm, on a 17x35mm rectangular frame. Read more about the characteristics of rectangular condenser capsules.

Although the mic’s advertised frequency response is 20Hz–25kHz, the -3dB points are closer to 45Hz and 14kHz.

The microphone name is engraved into the body, and painted pink to distinguish the CB22 from the CC22 (gold) and CO22 (white).

The CB22 can be paired with the cardioid CC22 for Mid-Side stereo applications, or with a second CB22 for Blumlein recording.

The mic ships in a padded aluminum flight case (p/n AC01). Two models of shockmount are available separately:

  • Model 1927 - essentially a rubber-lined mic clip
  • Model 1928 - a traditional elastic shockmount

The Pearl Microphone Laboratory CB 22 is also known as: CB22.
