      Comments about Audio-Technica AT2021 Cardioid Condenser Microphone:

      A pair of this microphone delivers the spatial perspective that I want and still place them in an unobtrusive manner. What is surprising is the fact that the more cost effective AT2021 has a brigther sound, suggesting a wider frequency response than the darker sounding and similar looking PRO37.

      • Q:

        Would this mic be effective for broadcasting a lecturer for a live web conference? There would be no post-processing. Thank you

          A:

          As with many things with audio; it depends. In the proper setup, yes the AT2021 would have a positive audio pickup.

      • Q:

        I am thinking of purchasing 6 of these to mic up a hand bell choir but am wondering what you think of the lower end of the choir, if these mics will pick that up as well as the top end of the choir?

      • Q:

        I'm looking to record marimba and vibraphone as well as reinforce sound for live performance. Will this mic reasonably fill both requirements? What placement would you recommend - one mic per instrument, two mics, above the bars, below the resonators, etc?
        Thanks in advance.

          A:

          Microphone placement is always subjective and I always recommend setting up wherever the microphones sound best.

      • Q:

        2021 vs pro37

        Hi Folks,

        They look similar, both high SPL, both almost flat response, but different price.

        So what do you recommend for low budget for horns or violins?

      • Q:

        Would the AT 2021 microphone benefit from a shock mount?

        I am getting a throbbing hum from my 2021 on a particular church altar. Some have suggested it is the lack of a shock mount. I notice that there is no shock mount designed for this microphone. I that because a mike that is so light does not need shock mounting?

      • Q:

        Can this mic take 18v phantom as supplied by MX34c?

        Yes, I read the specs that say it takes 48v phantom, but many microphones can support voltages less than that, and I would like to know if this one can do so without distortion. Thanks

        • A:

          Thank you for your inquiry. The microphone may work, but not to spec. I suspect that Max SPL. sensitivity and the signal to noise ratio would be off. It is designed to work with 48V.

      • Q:

        Would the 2021 work well for tuba in live reinforcement?
        Asked on 2/10/2013 by squeezekeys

        1 answer

        • A:

          Thank you for your inquiry. Yes, the frequency range and Maximum Sound Pressure Level (SPL) are all within that produced by a tuba. I would keep the mic 6" to 12" and slightly off axis from the bell for best sound.
