Audix TR-40A Reference Microphone

Audix TR-40A

 is a 6 mm pre-polarized condenser microphone used for test and measurement applications. The TR-40A is known for its linearity, accurate response, consistency, ease of use and affordability.

Characterized with a uniformly controlled omni-directional polar pattern, the TR-40A is designed to capture acoustical measurements for room analysis software programs, real time analyzers, and other sound control devices. With a wide frequency range of 20 Hz - 19 kHz, Audix TR-40A is an excellent tool for sound engineers and sound companies.

Requiring 9 - 52 Volts phantom power for operation, the TR-40A features a brass body with black e-coat finish and includes a mic clip and carrying pouch.

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.
