    Want that "high end sound" for a low end price?

    5

    I've had this mic for about 4 years and it still sounds incredible. I've paired it with better pre-amps over time and it shines even better in it's performance.

    Great value.

    I've had this mic for years. It's a good vocal mic. Sax, piano and acoustic guitar are especially favored I do not use this with electric guitar as there is too much break up on the low-end, tone is affected. (Get out the 58's..)

    Best for under $800

    Product is amazing for this price. Well thought out. Great for voiceovers and recording. I am a live streamer on Twitch and I use this as my daily driver for my weekly streams. I have never had a problem with it. Bass is great, and all other sound sounds crisp and clear. A LOT better than my previous, clip-on mic. Top of the line for under $500 - $800 I would say

    Go-To Vocal mic

    This has become my favorite mic in it's price range, for sure. I started using this for vocals and haven't looked back. The response is very crispy, a great high-mid responsiveness and it's high-end is a makes it sound just the perfect amount of airy. If you don't like that, you can always dial back the the highs using an EQ. All-in-all it makes a great vocals vocal mic. If you get a pair, it makes for a great spaced pair set for the drums or even piano. It captures the low-end nicely, as well. Versatile mic. Recommend for any studio.

    The build quality of this microphone seems very sturdy and solid. For sound quality, on the good side, this microphone works very well for high pitched instruments / bright formants. It adds more body to the lows and helps high instruments have more dynamic range. If you were just recording high pitched sources, then this is a great option. On the down side, this microphone does not handle low instruments / low formants at all. That low boost it gives will ruin the sound for low instruments. It's rough sounding and adjusting the microphone angle doesn't seem to help anything. So in all, this microphone is good for certain applications but definitely not low pitched sources.

    Excellent utility mics. Great to have a pair lying around.

    This microphone is one of those go anywhere do anything mics. It sounds good on lots of sound sources and also does an excellent job. I have used this mic for my sax recordings on albums, flutes, clarinets, guitar amps, pianos, and much more. It has a very even clean sound that is very easy to work with. It is not particularly colored or weighted mic, but it does have a slightly brighter sound than the at4047, which is also an excellent mic. So this mic tends to respond better to sound sources where clarity and bright sounds are preffered. (Strings, Piano, Room Micing, Cymbals) All in all this is a great all around studio mic that works great in a wide variety of applications. And the price is very good to boot.

    I have had my 4040s (2) for 3 years and have been very pleased with their solid performance rugged build and sonic quality. I use them in x/y and ORTF stereo configuration and have been very pleased with the sound stage these produce. What's amazing is a demo a fellow engineer showed when he tested a random pair of 4040s and 4050s and their response was with in 2dB of each other along the entire curve. WOW - exceptional!

  • Q & A

    I'd like to buy one AT4040 Microphone, and i'd like to know which desk stand should i use. And do i still need any connecting devices.

    Catherine

    Thank you for your inquiry. A shock mount is provided. Something like a broadcast arm would be a nice mount. If connecting to a computer you need an audio interface with 48V phantom power.

    Rick

    Does this AT 4040 condenser mic includes a shock mount?

    Aaron

    Yes, the AT4040 includes the AT8449a Shock Mount. http://www.audio-technica.com/cms/windscreens_mounts/444456a4a3b0804c/index.html

    I have a PreAmp (ART Pro MPA II) that has a setting for impedance and it goes from 150 all the way up to 3K. What is a typically good way to decide where to set this when using the AT4050 for vocals?

    Billy

    In order to transfer the maximum amount of voltage from the microphone to the preamp, set the preamp to the highest setting of 3000 ohms.

    sshaw

    Is this a lxr mic or usb mic?

    mr.diamondsword

    Thank you for your inquiry. This is an XLR connector, not USB.

    I am looking for a microphone to record lead trumpet with and I am curious if this would be the right microphone for me?

    TrumpetTown

    Thank you for your inquiry. Yes, this would be a great microphone for trumpet. Please see the video at this link for micing a trumpet. https://www.youtube.com/watch?v=4xt1SJoU6Us Please note in the video we are using an AT4050, which is another good microphone for this application.

    AudioSolutionsManager

    Is there a separately purchaseable windscreen for the AT4040?

    Alan

    The AT8137 will work with the AT4040. http://www.audio-technica.com/cms/windscreens_mounts/c16baec744cb808a/index.html

    I'm having trouble with getting my mic to work. I have an xlr to usb adapter that connects to my Lenovo 570 laptop. I've gone into the settings and made sure that the mic is enabled and all that stuff. As far as I can see there is no on/off button on the mic. I'm not very good with this stuff, so forgive my ignorance, but is there any way to get this mic to work that I haven't tried yet.

    Austin

    The AT4040, being a condenser microphone requires phantom power and an XLR to USB cable will not provide that. You may find helpful information on this subject here: http://blog.audio-technica.com/audio-solutions-question-of-the-week-can-the-at2020-microphone-be-used-to-record-into-a-computer/ Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at audio-solutions@atus.com for additional assistance with this.

    What kind of connecting cable should I use to connect the mic with my interface?

    Cindy

    Being a condenser microphone, you will need to provide phantom power to the microphone and you may use an inline audio interface. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at audio-solutions@atus.com for additional assistance with this.

    What size screw secures the body to the base of the AT4040? I am missing 2 of the 3 screws on one of my AT 4040 and need to replace them.

    I want to buy the AT 4040 and use it with a Zoom h5 digital recorder. Should i be worried about problems with phantom? The Zoom recorder has a setting for 48v phantom

    Gon

    You may plug the AT4040 microphone via an XLR cable into an XLR MIC level input with +48v of phantom power.
