Crown PZM-185 Pressure Zone Microphone

Excellent kick drum boundary microphone!

The PZM185 is a Pressure Zone Microphone for general-purpose use. The PZM185 is powered either by an internal AAA 1.5V battery or 12-48 volt phantom power. The boundary “paddle” can be detached so the mic will fit in your pocket. Attached to the mic is an 8-foot (2.438-m) cable leading to a tubular power module.

Its electret condenser capsule provides a wide, smooth frequency response from 50 Hz to 16 kHz . The mic’s hemispherical polar pattern allows clear pickup of everyone surrounding the microphone.

The PZM185 is protected against static and RFI. The output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. Like other Pressure Zone Microphones, the PZM185 uses a miniature mic capsule

mounted very near a sound-reflecting plate or boundary in the Pressure Zone.
