Audix TR40 Test and Measurement MicrophoneThe Audix TR40 Test and Measurement 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.

Measurement and Calibration
Because the TR-40 combines phase coherency with an extremely linear frequency response, it’s perfect for use as a cost-effective measurement or calibration microphone for many of today’s real-time room analyzers, automated equalizers, and software driven measurement programs.
Recording Techniques
Many recording engineers use the TR-40 as a creative tool to naturally blend the sound of an acoustic instrument with the room. This provides a unique character and dimension to a recording which cannot be achieved any other way. Instruments such as piano, acoustic guitar, percussion, saxophone, and percussion all lend themselves to this creative process.
Live Sound
The TR-40 can be used successfully for a variety of applications from choir miking to overhead drum miking. The most interesting and original use of the TR-40 will be as a room mic providing a real time mix for performers equipped with in-ear monitor systems.
Broadcast Application
A series of TR-40's can be strategically placed over the audience in order to create the live feeling of the event.
