Audix TR40 Omnidirectional Condenser Microphone for Measurement
The Audix TR40 is a test and measurement microphone that employs a 1/4" pre-polarized condenser capsule with an omni-directional polar pattern. You get an ultra-smooth, linear frequency response from 20Hz to 20kHz. The flat linear response enables the TR40 mic to successfully capture the "room effect" without the need to resort to electronic processing. This, along with the ease at which the Audix TR40 handles high SPL's of over 140dB, makes it an ideal testing mic for both studio and live recording of pianos, musical groups, choirs, and room acoustics.
