What type of power do the various Crown mic models require?

All Crown microphones are the condenser type (see above) and require power to operate. Most operate on standard 12- to 48-volt phantom power only, with the following exceptions:

  • The Sound Grabber II only works with the internal AAA-type battery. Be sure it is new, otherwise the mic level might be low.
  • The PZM-185 works with the internal AAA-type battery or external phantom power.
  • The head-worn CM-311A and CM-312A mics will work with the internal 9V battery or phantom power.
  • The PZM-10LL is powered by 12 to 24 VDC.
  • The PZM-11LL and PZM-11LLWR are powered by 12 to 24 VDC or phantom power.
  • Crown mics designed for wireless transmitter use only (CM-311AE, CM-312AE and GLM-100E) use the bias voltage supplied by the transmitter.
