      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.

        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..)

          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

              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.

                        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!

                              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.

                                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.

                              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

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

                              OK I just bought At4040 for commentary in gaming and I am using a PC and Audacity + Focusrite Scarlet 2i2 and the sound I am recording is very low. Should the mic be placed in some direction.

                                Being a condenser microphone, make certain you are plugging the microphone into the XLR input of the interface and engage the phantom power. Additionally, the AT4040 is a side address microphone and be certain to speak into the front of the diaphragm.

                                It appears the listed audio interface will provide +48v of phantom power which is sufficient for the AT4040 microphone.

                              I have an acoustic amp (Acoustic Model AG120S) that works fine with my condenser mike (CAC Model M177). The CAC mike accepts a wide range of phantom power. I have a second mike that happens to be your model AT4040. The AT4040 mike will not work at all with my AG120S amp. Is there a device that I can put between the amp (AG120S) and your model AT4040 that would serve to boost the phantom power to the 48v level.

                              Hi,I have an AT4040 and have been using it for many,many years with great success.I have used it in pre-amps and it's worked great.However,I just plugged it into a Behringer Xenyx Q502 USB Mix-amp and it works for a half-second then fades into some annoying static.The Mix-Amp seems to work with other microphones just fine (I also have a Blue Yeti Pro that I've had working with it) but,for some reason,it doesn't agree with the AT4040.Is there a compatibility issue here or am I missing something?

                                A:

                                Some higher end microphones such as some in our 40 Series require the full 48v of voltage to operate and some preamps (even that state they offer 48v) don't. The voltage is just under and really allows the mic to work, but not properly. This is sometimes found in preamps that are modeled after the older API. While great sounding preamps, some of the electronics consume some voltage. If the microphone works fine on other preamps, I would say this is what is happening.
