The TR40 microphone is the first in a series of test and recording microphones specially designed by Audix. The TR40 features a quarter-inch diameter pre-polarized condenser capsule with omnidirectional polar pattern. It delivers the extremely linear frequency response characteristics that Audix microphones are known for worldwide. Frequency response is 20 Hz to 19 kHz (+/- 1dB).

Many engineers prefer the phase coherent response that a mic such as the TR40 delivers. Its omnidirectional capsule is ideal for certain studio and live recording applications, such as piano, musical ensembles, and choirs. Another application in which the TR40 excels is ambient tracks frequently recorded by engineers to "open up" or add dimension to a track or a mix. Because of its flat frequency response, the TR40 can be positioned easily in any room to capture the room’s natural sound.

"Engineers have been using test and measurement mics in the recording studio for a number of years due to their smooth, linear frequency response," says Cliff Castle, Audix Vice President of Sales. "The TR40 will knock out engineers who are looking for a flat, smooth-sounding omnidirectional microphone. The mic can easily withstand very high SPL of more than 140 dB, making it an ideal choice for close miking a variety of instruments in studio or live recording applications," Castle says. Because of its flat linear response, the TR40 is a cost-effective solution as a test and measurement mic. The Audix TR40 is made of rugged machined aluminum and features a gold-plated XLR connector at the base.
