    AT4040 Cardioid Condenser Microphone 4.3 5 4 4
    this mic sounds amazing when i got it i thought "can be better than my neumann tlm102" well i was wrong sounds 50 times better than my neunann i love it. December 15, 2013
    Semi Versatile 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. December 7, 2013
    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. December 4, 2011
    Solid Performer at Any Price 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!

    Am i getting the right idea?

    Hey, I'm new to this whole audio recording thing. If i were to get an AT4040 mic and an M-AUDIO fast track pro interface, along with my laptop with garageband and imovie, i can start recording? Do those go together? Would i need another piece of hardware? What would you recommend? I would be recording acoustic guitar and vocals. Thanks for any help.

    Answer: 
    The short answer is yes and the long answer is what are you recording. There are really only 4 things you need to start making digital recordings:
    1 - Sound source worth recording. (Hardest thing to find)
    2 - A decent microphone. (AT4040 is a great choice for lots of things.)
    3 - A audio interface. (This has two functions: to act as an A/D converter for the signal coming from the microphone and a mic pre amp, which provides the juice to make the mic work.)
    4 - Software to record with. (Garageband works well for very basic recordings.)

    Really the only other things you need to ensure are:
    Drivers for MAC OSX for your M-AUDIO device.
    Some research on how to properly attach, power, place, and use your mic. (Trust me the first 100 recordings you do will be failures just simply cause you place the mic in the wrong spot.)
    You will also need the boring accesories that go along with recording: mic cables, headphones, mic stand, studio monitors(your macs built in speakers are like cell phone speakers so at least get a great pair of headphone. PS Audio-Technica makes some excellent ones.)

    Hope this all helps.

    Answer: 
    The AT4040 requires 48V of phantom power. If the interface provides 48V of phantom power and you use a good quality XLRM to XLRF microphone cable this should work ok.

    Answers

    Answer: 
    Phantom power is a term that denotes a boost in the amount of electricity that is passed from the mic pre amp to the microphone. The 48V that you often hear said with phantom power stands for 48 Volts which is what a condenser mic like the AT4040 requires to operate. Just think of these mics as having little computers in them that require an external power source to run. If your recorder does not have button for 48V or Phantom Power on it chances are it will not have this function and you will have to get an external power supply. You cannot run a condenser mic without phantom power. PS just to note many ribbon mics can actually be damaged by phantom power so be careful about just switching it on without knowing something about your mic.

    Answer: 
    Thank you for your inquiry. Phantom power is DC voltage sent down the microphone cable to power the preamplifier of a condenser mic capsule.

    A balanced mic cable has three conductors; Pin 1 is ground, Pin 2 is audio positive, and Pin 3 is audio negative. Most microphones produce a positive voltage on Pin 2 when sound pressure is applied to the diaphragm.

    Phantom power is 9 - 52VDC applied across Pin 1 and Pin 2 - and at the same time applied across Pin 1 and Pin 3. The term 'phantom power' was assigned because if you take a measurement across the two audio lines - Pin 2 and Pin 3 - you find 0 Volts DC. The voltage does not affect the mic signal.

    If your recorder does not provide phantom power you neeed to use an external phantom power supply, such as our AT8801.

    Answer: 
    There are plenty of preamps and interfaces that one could use with an AT4040. The right one depends on what you would like to do. Because of this, the BEST thing to do would be to contact an Authorized Audio-Technica Dealer for a recommendation. There is a Dealer Locator on the A-T homepage, www.audio-technica.com.

    I am not using the usb port on my mac (with FCP 7). I am using the single jack. I can't get a strong signal even with the gain turned up to 150. Do I need a USB or Firewire adapter for the mic? Or do I need some other audio interface between the mic and computer? Still confused.

    Answer: 
    Thank you for your inquiry. This will not work for two reasons. First, the input on Macs is line level verses microphone level and secondly, the microphone requires 48V of phantom power to operate. This connection does not provide phantom power. You will need a USB or Firewire audio interface to use this mic with your Mac.

    I've had this 4040 for several years, but haven't used it for the last 3-4 years, now trying to bring it back into service it seems to not put out very well. Am I doing something wrong? Or is it malfunctioning. It is plugged into phantom power.

    Answers

    Answer: 
    A few things you could do to troubleshoot your AT4040 are:
    1. Try with a different cable
    2. Try with a different input (make sure you adjust the preamp of your input device, properly).
    3. Try on a completely different input device that will send 48v of phantom power to the microphone.
    4. Make sure you are address the microphone from the front; not the top, or back.

    If nothing helps, Service will be recommended. For more information on obtaining Service with ATUS, please visit www.audio-technica.com/service.
