Mods for the AT2020

  • Microphone PartsMicrophone Parts
    MicParts’ upgrade kit for the AT2020 replaces 100% of the microphone’s internal parts: capsule, circuit, and wiring. The new capsule is 50% larger. The new circuit gives the mic cleaner transient response, superior bass response, and lower distortion.

Cardioid Condenser Microphone

The AT2020 is an inexpensive condenser microphone with a fixed Cardioid polar pattern.

The capsule is an electret, officially described as a “fixed-charge back plate, permanently polarized condenser”. In simpler terms, this means the mic circuit does not need to provide polarization voltage to the capsule.

AT2020 CircuitThe circuit is very simple, and uses surface-mount electronics. The mic also incorporates the smallest transformer we have ever seen.

AT2020 InternalsThe entire audio circuit and transformer fit on a 44mm diameter PCB that also supports the capsule mounting post. The lower half of the mic body is empty, save for a die-cut foam insert that presumably serves to eliminate body resonance.

The mic’s self-noise is somewhat high at 20dBA. With its moderate sensitivity (14.1 mV/Pa), this mic is likely better suited to loud sources than to distant miking or quiet acoustic instruments.

The AT2035 retains the same tonal characteristics [as the AT2020] while improving on its technical performance, by offering a flatter low-end response and significantly lower noise.

What is the AT2041SP “Studio miking essentials” Pack?

The AT2020 is bundled with a second small-diaphragm mic, the AT2021, in the AT2041SP “Studio Pack.” The AT2041SP bundle includes two stand mounts, two storage pouches, and a copy of SONAR LE recording software.

Resolution, 2005

[In] some ways it is more honest than some of its competitors in that its sound is obvious and apparent right out of the box, instead of having aspects of its response masked by electronic tuning which sometimes means that shortcomings are hidden until it’s too late…

[It] does a reasonable job of everything that you throw at it.
