  • Overview


    The classic edition of the legendary AT4033 microphone, the side-address AT4033/CL offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the AT4033/CL cardioid studio condenser is the microphone that broke the US$1000-barrier in its class. A strong up-front presence characterizes the sonic signature of this 40 Series pro-audio classic. The AT4033/CLís 80Hz high-pass filter easily switches between flat frequency response and a low-end roll-off that diminishes ambient noise and popping with closely-miked vocals.

    AT4033/CL Cardioid Condenser Microphone 4.5 5 2 2
    Just as good as the expensive mics I've been using this mic for 20 years, to record self-improvement albums. I wanted something that made my voice sound like those great radio and television announcers - intimate, powerful, great presence, warmth, power. With a little EQ and some compression in post (post production) it does exactly that. In 1990 we had an opportunity to record an album for Nightingale Conant, and I spent a lot of time talking with their recording engineer. We used an AKG 414C, which is supposed to be one of the best mics for recording a male voice. When I got home, I compared the recordings I made in the Nightingale studio with the recordings in my home studio and to me they sound equally good. The only difference I could hear - they leave more bass than I do. I EQ'd it out because we were still delivering the product on audio cassettes, and the sound was more clear when there was less bass. I've done a lot of recording with this mic, in my home studio, and it has always come through for me. I recommend it highly. July 23, 2013
    Excellent mic for the money... I've had one fo these in the cabinet for about 15 years (?!) now. It was my "go to" mic for quite a while, now it's simply for secondary use, ambient and the like. Noise floor is a little bit high, but you have to spend twice the $ to do much better. If you use a good mic-pre, you'll be all set (avoid the pre's that are built in to many mixers, but a stand alone, it's worth the $). For primary vocals, it has a bit of a bump in the 4-5k range, so you get some "up front" presence. Good for lead vocals. The only improvement I might make is to sell it at a lower price. HA!

    Answer: 
    Yes and No. The AT4033 is a classic mic that Audio-Technica has made for years. The letter after it the name represent the different changes they have made over the years to essentially the same mic. The CL is the newest version which stands for CLASSIC. If you have heard a AT4033CL and love it and are buying a AT4033a to try and match it, chances are you will probably hear small differences since it will be older and have small variations in parts, materials, and years of service. They are going to be very similar since they are both essentially the same mic, but the just won't be exactly the same.

    Answer: 
    Thank you for your inquiry. The AT4033/CL is really an AT4033a, but with the AT8449 Shock Mount. The AT4033a used the AT8441 Shock Mount. Also, the current AT4033/CL does not contain lead in the solder (in compliance with RoHS, the European directive for the Restriction of the Use of Certain Hazardous Substances in electrical and electronic equipment). Sonically, they are the same.

    Answer: 
    Thank you for your inquiry. It's not what one would normally consider to be a large diaphragm, but on the other hand it is not a small diaphragm either. it is somewhere in between.

    11.5 millimeter is the actual diaphragm size

    15.4 millimeters is the size including the baffle the diaphragm is mounted to.

    Thank you for your inquiry. The AT4030 was never sold by Audio-technica, U.S., so I have no specs for this microphone. I believe the AT4030 was exclusive to Europe.

    I am wanting to use the AT4033 as a ham radio microphone. I have a 48 volt external phantom power supply to operate the AT 4033.The ham radio supplies 8 volts to the mic and has to be between 250 and 600 ohms impedance. I have a 600 ohm in-line impedance matching transformer, so i believe i have the impedance covered. I'm really concerned about any voltage back to the ham radio from the microphone/phantom power supply. My radio is a TS 2000 Kenwood.

    Answer: 
    Thank you for your inquiry. If the external phantom power supply is designed properly it should flow only toward the microphone. Out AT8801 external phantom power supply works that way.

    My Audiogram 6 interface is supplying 48v to the AT4033/CL. I usually leave the computer, the interface and the microphone connected when performing other computer duties. Should I turn off the 48v. Should I disconnect the mic? Is it proper to shut off the 48v supply prior to pulling a connector? I love the microphone and just want to prolong it's useful life.

    Answer: 
    Thank you for your inquiry. Although, it should not harm the microphone it is always a good idea to shut down phantom power or at least mute the channel to keep the system form creating a very loud "poping" sound.
