      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:

        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

          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.

        Would the 2021 work well for tuba in live reinforcement?

        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.

      • Q:

        Will this microphone pick up vocals along with an acoustic guitar at the same time with the same quality?
        Asked on 8/30/2011 by Chase from Grove City

        2 answers

        • A:

          The simple answer is no. Most likely the guitar will over power the voice in the recording or if the mic is too close to your mouth, the mic will not pick up the guitar. You are far better off with a mic on the guitar and a mic for your voice. Small condenser mics are a little harsh on voice since they tend to down play the low parts of the voice and bring out high sounds. I would suggest a traditional hand held vocal mic on a stand or a large diaphragm condenser for that purpose. AT2021 will work good for the guitar though.

        • A:

          Thank you for your inquiry. You ask an interesting question and the answer is: "It depends". Many performers, as well as those making recordings will use a single microphone for both vocals and acoustic guitar, but it can take some work to get the sound you want. Positioning the microphone may be a challenge to find the perfect volume level for both vocals and guitar. Feedback may also be an issue because neither your mouth nor the instrument is very close to the microphone. This brings the inverse square law into play meaning that every time you double the distance of the sound source from the microphone you decrease the volume by half. This means you will need to up the volume on your mixer, which could lead to feedback. Another possible issue is EQ. For the best sound, you may want to EQ the microphone differently for vocals than you would for guitar. If you use a single microphone you will need to split the difference. By all means, try using just one AT2021 and see if it meets your need. If not, you can always add a vocal mic and use the AT2021 on guitar alone.

        AT2041 Studio Microphone Package

        Are both microphones being sold on Amazon as the AT2041 Studio Microphone Package USB connectors? I have the AT2020 here at home which is USB but I am unsure if both of the mics in the AT2041 Studio Microphone Package are USB.
        Asked on 8/19/2011 by TA101 from USA

        • A:

          Probably not. If it does not actually say USB on the mic chances are it is not a USB mic. Most of the time the packages are for conventional XLR Plugs.

        • A:

          Thank you for your inquiry. Neither microphone in the AT2041 Studio Pack has a USB connector. We do offer the AT2020 as a stand alone USB version (AT2020USB).
