  • Overview


    The latest edition of the legendary AT4033 microphone, the side-address AT4033a offers low-noise, symmetrical, transformerless circuitry that results in exceptional transient response and clean output signals. A studio classic and bluegrass favorite, the AT4033 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 AT4033as 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. Includes the AT8449a shock mount for superior isolation.

    *The AT4033a is the same microphone as the AT4033/CL. The AT4033a comes equipped with the AT8449a shock mount whereas the AT4033/CL included the AT8449 shock mount.*
  • Features


    • Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients

    • Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity

    • The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use

    • Floating-construction capsule assembly provides isolation from noise and vibration

    • Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections

    • State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards

    • Custom shock mount provides superior isolation

        Comments about Audio-Technica AT4033/CL Cardioid Condenser Microphone:

        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.

            Comments about Audio-Technica AT4033/CL Cardioid Condenser Microphone:

            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!

                Thank you for your inquiry. I would recommend going with the AT4033/CL. That mic has been used/recommended for lead vocals for the last 15-20 years I'm sure it will work well for you!

            • Q:

              Is it a good idea to use two of the 4033/cl mics side by side in a live bluegrass stage performance.? I have tried to do this with no success. I just get terrible "howling" and feedback. What are the two switches on this unit and what are some examples of when and how they they should be used.? Is there a instruction manual and/or user guide for this unit? Where can I find it? Many thanks for these answers!!

            • Q:

              Our AT4033 mic has suddenly gone real quiet. In testing it out, I note that when I engage the pad switch to either O or -10db the volume shoots back up to where I think it should be and then within 5-10 seconds, it fades to a very low output level.

              Hi,
              I have three of these great microphones. 1 at4033 and two at4033A's.
              One of the 4033As is 3.5dB quieter than the others but similar sound, perhaps not quite as deep.
              Is this a fault? (it was bought second hand)
              Kind Regards

                A:

                This mic is great to record a guitar amp with! But if you are trying to plug the mic directly into the amp via a XLR-1/4'' cable, it won't work as this type of cable cannot distribute Phantom Power, which is needed to power the mic.

                A:

                Absolutely it will! This mic would operate best on more clean-type performances. This mic is transformerless which allows it to have excellent transience. This mic also has an 80 Hz high-pass filter so it can best adapt to whatever recording situation you are in!
