  • Overview

    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).

        Comments about Audio-Technica AT5045 Cardioid Condenser Instrument Microphone:

        When my church commissioned me and my company to design, install and maintain new audio, video and lighting systems for our two campuses, I was told to do what I think is best. I have experience with just about every microphone there is on piano. I chose to use these mics, ear unheard, because of the recommendation of my rep Michael Canning and a couple of people who had heard the beta units. We did a shoot out with several other mics AKG, DPA, Earthworks, Shure and Neumann. These mics worked best, In fact, we use no EQ whatsoever on the piano. We were able to place the mics where they needed to be. The mounts are stellar. I would highly recommend these mics for recording as well.

        • Q:

          I Wonder if you believe the AT5045 would be suitable in a small Acoustic live setting for an audience of around 30 people. The setting is only me flatpicking a Marting D-28 and singing. Seperate vocal mic and AT5045 for the guitar going through two seperate channels into a high end acpustic amp. Any thoughts?

            Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this. Each setup may be different and I would say if your sound system is tuned and not prone to feedback, you may be able to use the AT5045 in a live setting.

        • Q:

          Frequency curve

          Why does the website show a peak at 3.6k and the data sheet showson more like 6k? If I were to spend over a thousand dollars on a mic that would make a significat difference. What is the real curve?

            Thanks for pointing this out. Both the Polar Pattern and the Frequency Response plots on the website are incorrect. The plots on the data sheet are correct.
