Studio Instrument Microphone
Available as a single mic or as a stereo pair, the AT5045 is Audio-Technica’s premier condenser instrument microphone, offering the performance of a large-diaphragm, side-address condenser in a convenient, stick-type body. In fact, despite the space limitations imposed by its housing, the AT5045 boasts Audio-Technica’s largest single diaphragm. The instrument microphone’s circuitry has been honed to the essentials, allowing the AT5045 to achieve an unprecedented dynamic range that’s one of the widest of any microphone on the market.

100% quality control
Every AT5045 is hand assembled and individually inspected for 100% quality control. Each microphone is enclosed in an elegant housing of aluminum and brass with a high-quality gray finish for durability and low reflectivity.

Discrete components have been selected for optimized performance. The circuitry and capsule assembly are mounted as a single block within a floating internal shock mount, effectively decoupling the capsule from the microphone body for excellent vibration isolation. In fact, every aspect of the microphone has been carefully considered to minimize any negative effects on the audio signal.

The AT5045 instrument mic comes with Audio-Technica’s innovative AT8481 isolation clamp, an AT8165 windscreen and a protective carrying case that holds a single AT5045 microphone or a stereo pair of AT5045 microphones.

Available as a single microphone (AT5045) or as a stereo pair (AT5045P).
