This document describes the features and usage of the CM15P and CM20P miniature cardioid gooseneck microphones produced by Samson Technologies Corp. These microphones have a flexible gooseneck design and cardioid pickup pattern, suitable for podium speeches and other scenarios.
The Samson CM15P (15-inch) and CM20P (20-inch) are miniature gooseneck condenser microphones designed for podium or table-top use. They feature a permanently charged element with a cardioid pickup pattern, providing good off-axis response while maintaining high feedback rejection. The units include an onboard 100Hz high-pass filter to attenuate low-frequency noise and come equipped with a standard XLR connector and a dual-stage windscreen.

No, they are condenser microphones that operate using a standard phantom power supply of 9 through 52 volts.
It attenuates low frequency response to help remove background noise, stage rumble, and mechanical noise.
The cardioid pattern rejects signal coming from behind or the side of the microphone, minimizing feedback problems when placed near loudspeakers.
